&lt;p&gt;&lt;strong&gt;&amp;quot;Le dernier bar avant la fin du monde&amp;quot;&lt;br /&gt;
19 avenue Victoire&lt;br /&gt;
75001 Paris&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;&lt;a href="https://pintofscience.fr/"&gt;Registration&lt;/a&gt; opens on 13 April 2026&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;&amp;nbsp;&lt;/p&gt;

&lt;h2&gt;Programme&lt;/h2&gt;

&lt;p&gt;In 2026, we will welcome six scientists, including researchers and doctoral students. Maria Gutierrez (PhD) will also support the FC3R in her role as facilitator.&lt;/p&gt;

&lt;h2&gt;&lt;span style="color:#f07f5e"&gt;Monday 18 May - From gut to chip&lt;/span&gt;&lt;/h2&gt;

&lt;p&gt;Intestines grown in the laboratory to understand inflammation and cancer, and kidneys on a chip to study kidney disease. Two research projects that recreate our organs in miniature to better observe and understand what happens inside the body and devise new treatments.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Intestinal organoids need immunity&lt;/strong&gt;&lt;br /&gt;
&lt;span style="color:#57b1db"&gt;Lionel Le Bouris &amp;ndash; Researcher, Inserm&lt;/span&gt;&lt;br /&gt;
What happens in our intestines when they become inflamed? Why don&amp;#39;t colon cancers respond well to the new immunotherapies that have changed how other cancers are treated? Are animal models the best way to answer these questions? Lionel Le Bouris develops organoids from patient samples and then studies how these structures interact with the immune cells of those same patients. His goal is to reduce the activation of immune cells in inflammatory diseases, but increase it against cancers.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;It&amp;#39;s nothing, sweetheart!&lt;/strong&gt;&lt;br /&gt;
&lt;span style="color:#57b1db"&gt;Aliz&amp;eacute;e Fernandes Pereira &amp;ndash; PhD student, Sorbonne University&lt;/span&gt;&lt;br /&gt;
What if a kidney (or almost) could fit in the palm of your hand? During this futuristic evening, Aliz&amp;eacute;e Fernandez Pereira will guide you through her thesis work. The agenda includes miniature kidneys on a chip, human cells and sensors. The idea? To better understand kidney disease and find new ways to treat it. Research that&amp;#39;s close to science fiction... but within reach - and you won&amp;#39;t even have to leave the bar!&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;&lt;/p&gt;

&lt;h2&gt;&lt;span style="color:#f07f5e"&gt;Tuesday 19 May - Tomorrow&amp;#39;s healthcare: AI and mini-tumours&lt;/span&gt;&lt;/h2&gt;

&lt;p&gt;What if medicines were designed by AI, and tumours were grown on chips rather than in mice? Between algorithms and mini-cancers in the lab, discover how research is reinventing the way we test and create the treatments of tomorrow.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;ChatGPT, make me a medicine!&lt;/strong&gt;&lt;br /&gt;
&lt;span style="color:#57b1db"&gt;Luigi Ranieri &amp;ndash; PhD student, Paris Cit&amp;eacute; University. Inserm&lt;/span&gt;&lt;br /&gt;
What if the next medicine you took had been designed using artificial intelligence? Today, developing a treatment takes 15 to 20 years, costs billions of euros, and involves several animal tests. Artificial intelligence is changing the game. Thanks to machines that analyse large amounts of biological data, we can now predict which compounds are most likely to become medicines. This reduces animal testing and minimizes failures. Come and find out if AI could replace chemists like Luigi Raneiri! (Spoiler: no.)&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Minion chips to grow mini-tumours in the laboratory&lt;/strong&gt;&lt;br /&gt;
&lt;span style="color:#57b1db"&gt;Anna Schreiber &amp;ndash; PhD student, Paris Cit&amp;eacute; University&lt;/span&gt;&lt;br /&gt;
Colorectal cancer is one of the most common cancers, and developing new treatments requires numerous tests, which are often carried out on mice. To limit this practice, Anna Schreiber has developed a small, ingenious Minion chip (resembling Bob) that can reproduce key aspects of colorectal cancer in vitro. The chip can be used to grow tumour spheroids -small balls of cancerous or malignant cells - providing a more ethical, rapid and relevant model for testing new treatments.&lt;/p&gt;

&lt;h2&gt;&lt;span style="color:#f07f5e"&gt;Wednesday 20 May &amp;ndash; The private life of microbes&lt;/span&gt;&lt;/h2&gt;

&lt;p&gt;Microbes lead much more eventful lives than we realise. This evening event reveals their most intimate secrets, from a parasite with a secret love life to bacteria that have evolved from being a threat to becoming a food source.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;The hidden sex life of the Leishmania parasite&lt;/strong&gt;&lt;br /&gt;
&lt;span style="color:#57b1db"&gt;Marcela Fuentes &amp;ndash; PhD student, Institut Pasteur&lt;/span&gt;&lt;br /&gt;
Even microorganisms have a love life! Leishmania, a parasite transmitted by insects called sandflies, can cause the serious disease leishmaniasis. For a long time, it was thought that it only divided in order to multiply, until it was discovered that it also led a well-hidden sex life. In her project, Marcela Fuentes is studying a protein called Gex1, which is essential for Leishmania to reproduce. Want to delve into the secrets of seduction on a microscopic scale? Come and find out how this parasite finds &amp;mdash; or loses &amp;mdash; love!&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Did you know that yoghurt used to be sold in pharmacies?&lt;/strong&gt;&lt;br /&gt;
&lt;span style="color:#57b1db"&gt;Anne Hiol &amp;ndash; Postdoctoral researcher, INRAe&lt;/span&gt;&lt;br /&gt;
In the past, bacteria were feared: they were accused of poisoning us from within. Today, we eat them for breakfast without hesitation. So what happened in between?&lt;br /&gt;
In her talk, Anne Hiol recounts how yoghurt went from being a remedy sold in pharmacies to becoming a popular food, thanks to the efforts of scientists and Nobel Prize winners, as well as a few lactic ferments. You&amp;#39;ll never look at yoghurt in the same way again afterwards!&lt;/p&gt;]]></content><enclosure url="https://www.fc3r.com/actualites/d/122-vignettepintofscience.jpg"  type="image/jpeg" lenght="960" /><image><title>Illustration</title><link>https://www.fc3r.com/actualites/d/122-vignettepintofscience.jpg</link><url>https://www.fc3r.com/actualites/d/122-vignettepintofscience.jpg</url><width>960</width></image></item><item><title>Clémence Deligne, winner of the FC3R 2025 3Rs Research Award</title><link>https://www.fc3r.com/actualites/fc3r-2025-3rs-research-award-120.html</link><pubDate>05 Mar 2026</pubDate><description><![CDATA[The FC3R has awarded its 2025 3Rs Research Prize to Clémence Deligne for her publication on the development of an organoid biobank for the study and treatment of paediatric brain cancers.]]></description><content><![CDATA[&lt;h2&gt;FC3R: Can you introduce yourself and tell us about your background?&lt;/h2&gt;

&lt;p&gt;I am a postdoctoral researcher at &lt;a href="https://www.crcl.fr/" target="_blank"&gt;the Lyon Cancer Research Centre&lt;/a&gt; (CRCL), at the L&amp;eacute;on B&amp;eacute;rard Centre, in the &amp;quot;&lt;a href="https://www.crcl.fr/equipes-de-recherche/mort-cellulaire-et-cancers-de-lenfant/" target="_blank"&gt;Cell States and Childhood Cancers&lt;/a&gt;&amp;quot; team, co-led by Dr Marie Castets and Prof. Jean-Yves Blay. We work specifically on paediatric cancers, especially sarcomas and brain tumours.&lt;/p&gt;

&lt;p&gt;During my PhD at &lt;a href="http://lbhe.univ-artois.fr/" target="_blank"&gt;the Blood-Brain Barrier Laboratory&lt;/a&gt; in Lens, I developed 2D multicellular in vitro models to study interactions between blood-brain barrier cells and infiltrating glioma cells in Diffuse Intrinsic Pontine Glioma (DIPG), a highly aggressive pediatric brainstem cancer. I then wanted to take my modelling of paediatric brain tumours a step further by joining Dr Laura Broutier&amp;#39;s group at CRCL for my postdoctoral research. Since then, I have been working on the development of 3D tumour organoid models, also known as tumoroids, of high-grade paediatric gliomas, including DIPG.&lt;/p&gt;

&lt;p&gt;These tumoroid models allow us to apply the 3Rs principle, as we do not use animals to model and study these particular tumours.&lt;/p&gt;

&lt;h2&gt;FC3R: Can you tell us about the award-winning work?&lt;/h2&gt;

&lt;p&gt;Childhood cancers are rare, accounting for only about 1-2% of all cancers. However, they remain the leading cause of disease-related death in children. Although up to 80% of children with cancer can now be successfully treated, some cancers, such as high-grade gliomas and posterior fossa ependymomas, remain extremely difficult to cure.&lt;/p&gt;

&lt;p&gt;One reason for this is partly due to the heterogeneity of these tumours. There are several subtypes of high-grade gliomas, which is known as inter-tumour heterogeneity. There is also intra-tumour heterogeneity, meaning that there are several cell populations coexist within the same tumour, and some of these populations will&amp;nbsp;be resistant to treatment.&lt;/p&gt;

&lt;p&gt;It is&amp;nbsp;in this context, under the leadership of Laura Broutier and Arthur Tourbez, that we have developed tumoroid models of the deadliest paediatric glial tumours, i.e. high-grade paediatric gliomas, including DIPG and posterior fossa ependymomas. Tumoroids are miniature versions&amp;nbsp;of tumours that we generate in vitro in the laboratory. These models accurately represent the heterogeneity of the original tumours and allow us to identify which treatments, or combinations of treatments, are most effective.&lt;/p&gt;

&lt;p&gt;I would also like to emphasise that this work is the result of a team effort, and I would like to thank everyone involved.&lt;/p&gt;

&lt;p&gt;&lt;img alt="" src="https://www.fc3r.com/actualites/d/120-actuprixrec2025.jpg" style="width:100%" /&gt;&lt;/p&gt;

&lt;h2&gt;FC3R: How are these organoid models generated? From biopsies or from human embryonic stem cells?&lt;/h2&gt;

&lt;p&gt;We collaborate with surgeons and pathologists at &lt;a href="https://www.chu-lyon.fr/" target="_blank"&gt;the Hospices Civils de Lyon,&lt;/a&gt; who give us access to biopsy samples and surgical resections. Even from small tumour fragments, we are able to establish &amp;nbsp;tumoroid cultures using the protocols we have developed, thereby expanding the starting material. These models can be cultured stably for months, or even years, and can be frozen and thawed as needed for our projects.&lt;/p&gt;

&lt;h2&gt;FC3R: It is often said that organoids are not as &amp;quot;mature&amp;quot; as the original tissues in adults. Is this also the case for your tumoroids?&lt;/h2&gt;

&lt;p&gt;We carried out a very comprehensive characterisation of our tumoroid models at the histological, transcriptomic, genomic, epigenomic and functional levels. This exhaustive characterisation has enabled us to demonstrate that our tumoroid models faithfully reproduce the characteristics of the original tumours.&lt;/p&gt;

&lt;h2&gt;FC3R: It is often reported that tumours are not homogeneous from a cellular and even genetic point of view.&lt;/h2&gt;

&lt;p&gt;Indeed, tumours are not made up of a single cell population, but of several cell populations that may differ genetically, in particular through genetic mutations that can drive resistance. We demonstrated through targeted DNA sequencing and bioinformatic analyses that the same clonal mutations were found in our models as those found in the original tumours, and in similar proportions. We also confirmed the presence of the different cellular states found in biopsies of high-grade gliomas using the single-cell RNA sequencing technique. This is one of the key strengths of our study, because intra-tumour heterogeneity is a major source of treatment resistance. So reproducing this diversity in our models is therefore essential if we want to reflect the same resistance mechanisms found in patients.&lt;/p&gt;

&lt;h2&gt;FC3R: In vitro models based on human cells, including organoids, are relevant for humans, but are they also clinically relevant?&lt;/h2&gt;

&lt;p&gt;Indeed, &amp;quot;clinical relevance&amp;quot; is an essential criterion for models used in translational research in order to generate robust results that can be transferred &amp;quot;from bench to bedside&amp;quot;.&lt;/p&gt;

&lt;p&gt;In our study, we established tumoroid models before and after chemotherapy in two patients. We then exposed these tumouroid models to the same treatment received by the patient and observed an in vitro response that mirrored the clinical response. This allowed us to demonstrate the predictive, and therefore clinically relevant potential, of our models, which is a major strength of our study and allows us to move towards the promising prospects for personalised medicine.&lt;/p&gt;

&lt;h2&gt;FC3R: How do you apply the 3Rs principle in your research?&lt;/h2&gt;

&lt;p&gt;The ability of our tumoroid models to generate sufficiently clinically relevant results allows them to replace, at least partially, animal models in key preclinical studies, such as evaluating drug response or identifying resistance mechanisms. In addition, by enabling in vitro selection of the most promising therapeutic combinations prior to in vivo validation, our models improve animal welfare by limiting their exposure to ineffective or invasive experimental protocols.&lt;/p&gt;

&lt;h2&gt;FC3R: Do you use a &amp;quot;seeding and amplification&amp;quot; step in immunodeficient mice?&lt;/h2&gt;

&lt;p&gt;No, this step is not necessary. Thanks to the work we have done to develop the tumour tissue dissociation and culture medium protocol, we are able to obtain sufficient viable cells that proliferate directly in vitro and retain their original characteristics. This direct in vitro expansion method allows us to avoid contaminating human material with murine cells, which can occur during xenotransplantation in mice.&lt;/p&gt;

&lt;h2&gt;FC3R: How do you share these advances?&lt;/h2&gt;

&lt;p&gt;We support open and collaborative science, which helps to accelerate research in paediatric oncology.&lt;/p&gt;

&lt;p&gt;All our transcriptomic and genomic data are available in open access on the Neuro-Oncology journal website. Our omic data will also be accessible via the &lt;a href="https://www.ihope.fr/la-recherche/share4kids-un-entrepot-de-donnees-unique-en-france-sur-les-cancers-pediatriques/" target="_blank"&gt;Share4Kids platform&lt;/a&gt;, a multi-omic data repository in paediatric oncology shared with the entire scientific community. This project was launched by Dr Marie Castets in 2018 and awarded the Unicancer prize in 2023.&lt;/p&gt;

&lt;p&gt;Our models are available via Model4Kids, in the form of academic and industrial collaborations, in order to advance the discovery of more effective and less toxic drugs or therapeutic combinations.&lt;/p&gt;

&lt;h2&gt;FC3R: What about the future?&lt;/h2&gt;

&lt;p&gt;We want to move towards personalised medicine, in collaboration with Dr Pierre Leblond, a paediatric oncologist at &lt;a href="https://www.ihope.fr/" target="_blank"&gt;IHOPe&lt;/a&gt;. In parallel with the molecular profiling routinely carried out when treating a child with a brain tumour, we will culture tumour cells in the laboratory and test different drugs within two weeks to find out which ones are most effective in vitro. This will quickly provide us with a personalised map of therapeutic sensitivities that tells clinicians which drugs are most likely to work for each child, particularly if the first treatment fails. This approach would also help rule out treatments that are prescribed out of habit and would be completely ineffective for the patient, thus avoiding exposure to &amp;quot;unnecessary&amp;quot; toxicities.&lt;/p&gt;

&lt;h2&gt;FC3R: What does this 3Rs Research Award mean to you?&lt;/h2&gt;

&lt;p&gt;I have never worked with animals myself, either during my PhD or my postdoctoral studies. I have always been committed to contributing to the development of increasingly complex in vitro models, and I remain fascinated by the technological advances made in better representing healthy and tumour tissues in vitro by incorporating their microenvironments. Building this bridge between animal models and organoid models is important. I am not saying that we will be able to completely replace animal models, but we can limit their use considerably by reserving them for later-stage preclinical studies. This 3Rs Award therefore recognises these efforts to develop more ethical and potentially more predictive preclinical models to accelerate the discovery of more effective and less toxic treatments in paediatric oncology.&lt;/p&gt;]]></content><enclosure url="https://www.fc3r.com/actualites/d/120-actuprixrec2025.jpg"  type="image/jpeg" lenght="960" /><image><title>Illustration</title><link>https://www.fc3r.com/actualites/d/120-actuprixrec2025.jpg</link><url>https://www.fc3r.com/actualites/d/120-actuprixrec2025.jpg</url><width>960</width></image></item><item><title>Festival Pint of Science : rencontrez les chercheurs en dehors de leur laboratoire</title><link>https://www.fc3r.com/actualites/festival-pint-of-science-2026-121.html</link><pubDate>05 Mar 2026</pubDate><description><![CDATA[Le FC3R vous invite à rencontrer des scientifiques ayant appliqué le principe des 3R du 18 au 20 mai 2026 à Paris.]]></description><content><![CDATA[&lt;p&gt;&lt;strong&gt;Du lundi 18 au mercredi 20 mai, de 19 &amp;agrave; 22h, nous vous donnons rendez-vous au bar&amp;nbsp;:&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;&amp;laquo;&amp;nbsp;Le dernier bar avant la fin du monde&amp;nbsp;&amp;raquo;&lt;br /&gt;
19 avenue Victoire&lt;br /&gt;
75001 Paris&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;&lt;a href="https://pintofscience.fr/" target="_blank"&gt;Sur inscription&lt;/a&gt; &amp;agrave; partir du 13 avril 2026&lt;/strong&gt;&lt;/p&gt;

&lt;h2&gt;&amp;nbsp;&lt;/h2&gt;

&lt;h2&gt;Programme&lt;/h2&gt;

&lt;p&gt;En 2026, six scientifiques &amp;mdash; chercheurs et doctorants &amp;mdash; participeront &amp;agrave; l&amp;rsquo;&amp;eacute;v&amp;eacute;nement. Le FC3R pourra &amp;eacute;galement compter sur l&amp;rsquo;appui de Maria Gutierrez (PhD) pour assurer l&amp;rsquo;animation des rencontres.&lt;/p&gt;

&lt;h2&gt;&lt;span style="color:#f07f5e"&gt;Lundi 18 mai : Du bide &amp;agrave; la puce&lt;/span&gt;&lt;/h2&gt;

&lt;p&gt;Des intestins cultiv&amp;eacute;s en laboratoire pour comprendre l&amp;rsquo;inflammation et le cancer, et des reins sur puce pour &amp;eacute;tudier les maladies r&amp;eacute;nales. Deux projets de recherche qui recr&amp;eacute;ent nos organes en miniature pour mieux observer et comprendre ce qui se passe &amp;agrave; l&amp;rsquo;int&amp;eacute;rieur du corps et imaginer de nouveaux traitements.&lt;/p&gt;

&lt;p&gt;&lt;span style="font-size:22px"&gt;&lt;strong&gt;Les organoides d&amp;#39;intestin demande l&amp;#39;immunit&amp;eacute;&lt;/strong&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style="color:#57b1db"&gt;Lionel Le Bouris &amp;ndash; Chercheur, Inserm&lt;/span&gt;&lt;br /&gt;
Que se passe-t-il dans notre intestin lorsque celui-ci d&amp;eacute;veloppe une maladie inflammatoire ? Pourquoi les cancers du c&amp;ocirc;lon r&amp;eacute;pondent-ils peu aux nouvelles immunoth&amp;eacute;rapies qui ont r&amp;eacute;volutionn&amp;eacute; le traitement des autres cancers ? Pour r&amp;eacute;pondre &amp;agrave; ces questions, les mod&amp;egrave;les animaux sont-ils pertinents et suffisants ? Lionel Le Bouris d&amp;eacute;veloppe des organo&amp;iuml;des &amp;agrave; partir de pr&amp;eacute;l&amp;egrave;vements de patients et &amp;eacute;tudie ensuite comment ces structures interagissent avec les cellules immunitaires des ces m&amp;ecirc;mes patients. Son objectif : r&amp;eacute;duire l&amp;rsquo;activation des cellulaires immunitaire dans les maladies inflammatoires, mais l&amp;rsquo;augmenter contre les cancers.&lt;/p&gt;

&lt;p&gt;&lt;span style="font-size:22px"&gt;&lt;strong&gt;Ce n&amp;#39;est rein ma puce&amp;nbsp;!&lt;/strong&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style="color:#57b1db"&gt;Aliz&amp;eacute;e Fernandes Pereira &amp;ndash; Doctorante, Sorbonne Universit&amp;eacute;&lt;/span&gt;&lt;br /&gt;
Et si un rein (ou presque) tenait dans la paume de la main ? Lors de cette soir&amp;eacute;e futuriste, Aliz&amp;eacute;e Fernandez Pereira vous embarquera dans des travaux de sa th&amp;egrave;se. Au programme : reins miniatures sur puce, cellules humaines et capteurs. L&amp;rsquo;id&amp;eacute;e ? Mieux comprendre les maladies r&amp;eacute;nales et trouver de nouvelles pistes pour les traiter. Une recherche proche de la science-fiction&amp;hellip; mais &amp;agrave; port&amp;eacute;e de main (et sans quitter le bar).&lt;/p&gt;

&lt;h2&gt;&lt;span style="color:#f07f5e"&gt;Mardi 19 mai :&amp;nbsp;Soigner demain autrement : IA et mini-tumeurs&lt;/span&gt;&lt;/h2&gt;

&lt;p&gt;Et si les m&amp;eacute;dicaments &amp;eacute;taient con&amp;ccedil;us par une IA, et les tumeurs cultiv&amp;eacute;es sur puce plut&amp;ocirc;t que sur des souris ? Entre algorithmes et mini-cancers en labo, d&amp;eacute;couvrez comment la recherche r&amp;eacute;invente la mani&amp;egrave;re de tester et cr&amp;eacute;er les traitements de demain.&lt;/p&gt;

&lt;p&gt;&lt;span style="font-size:22px"&gt;&lt;strong&gt;ChatGPT, fais-moi un m&amp;eacute;dicament !&lt;/strong&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style="color:#57b1db"&gt;Luigi Ranieri &amp;ndash; Doctorant, Universit&amp;eacute; Paris Cit&amp;eacute;. Inserm&lt;/span&gt;&lt;br /&gt;
Et si le prochain m&amp;eacute;dicament que vous prendrez avait &amp;eacute;t&amp;eacute; con&amp;ccedil;u par une intelligence artificielle ? Aujourd&amp;rsquo;hui, d&amp;eacute;velopper un traitement prend 15 &amp;agrave; 20 ans, co&amp;ucirc;te des milliards d&amp;rsquo;euros et demande plusieurs tests sur des animaux. Derni&amp;egrave;rement, l&amp;rsquo;intelligence artificielle change la donne : gr&amp;acirc;ce &amp;agrave; des machines qui analysent une grande quantit&amp;eacute; de donn&amp;eacute;es biologiques, on arrive &amp;agrave; pr&amp;eacute;dire quels compos&amp;eacute;s ont le plus de chances de devenir des m&amp;eacute;dicaments, en r&amp;eacute;duisant l&amp;rsquo;exp&amp;eacute;rimentation animale et les &amp;eacute;checs. Venez donc d&amp;eacute;couvrir si l&amp;rsquo;IA pourra remplacer les chimistes comme Luigi Raneiri ! (Spoiler : non)&lt;/p&gt;

&lt;p&gt;&lt;span style="font-size:22px"&gt;&lt;span style="color:#1d3d91"&gt;&lt;strong&gt;Des puces Minion pour faire pousser des mini-tumeurs en laboratoire&lt;/strong&gt;&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style="color:#57b1db"&gt;Anna Schreiber &amp;nbsp;&amp;ndash; Doctorante, Universit&amp;eacute; Paris Cit&amp;eacute;&lt;/span&gt;&lt;br /&gt;
Le cancer colorectal est l&amp;rsquo;un des cancers les plus fr&amp;eacute;quents, et le d&amp;eacute;veloppement de nouveaux traitements n&amp;eacute;cessite de nombreux tests, souvent r&amp;eacute;alis&amp;eacute;s sur des souris. Pour limiter ce recours, Anna Schreiber a d&amp;eacute;velopp&amp;eacute; une puce Minion, petite, maligne, (et qui ressemble un peu &amp;agrave; Bob), capable de reproduire des aspects cl&amp;eacute;s du cancer colorectal in vitro. Cette puce permet notamment de faire pousser des sph&amp;eacute;ro&amp;iuml;des tumoraux, c&amp;rsquo;est-&amp;agrave;-dire de petites sortes de boules de cellules canc&amp;eacute;reuses/malignes, offrant un mod&amp;egrave;le plus &amp;eacute;thique, rapide et pertinent pour tester de nouveaux traitements.&lt;/p&gt;

&lt;h2&gt;&lt;span style="color:#f07f5e"&gt;Mercredi 20 mai :&amp;nbsp;La vie priv&amp;eacute;e des microbes&lt;/span&gt;&lt;/h2&gt;

&lt;p&gt;Les microbes ont une vie bien plus mouvement&amp;eacute;e qu&amp;rsquo;on ne l&amp;rsquo;imagine. Entre un parasite qui cache une vraie vie amoureuse et des bact&amp;eacute;ries pass&amp;eacute;es de menace &amp;agrave; aliment, cette soir&amp;eacute;e d&amp;eacute;voile leurs secrets les plus intimes.&lt;/p&gt;

&lt;p&gt;&lt;span style="font-size:22px"&gt;&lt;strong&gt;La vie sexuelle cach&amp;eacute;e du parasite Leishmania&lt;/strong&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style="color:#57b1db"&gt;Marcela Fuentes - Doctorante, Institut Pasteur&lt;/span&gt;&lt;br /&gt;
M&amp;ecirc;me les micro-organismes ont une vie amoureuse ! Leishmania, un parasite transmis par des insectes appel&amp;eacute;s phl&amp;eacute;botomes, peut provoquer une maladie grave appel&amp;eacute;e leishmaniose. Longtemps, on pensait qu&amp;rsquo;il ne faisait que se diviser pour se multiplier&amp;hellip; jusqu&amp;rsquo;&amp;agrave; ce qu&amp;rsquo;on d&amp;eacute;couvre qu&amp;rsquo;il menait aussi une vie sexuelle bien cach&amp;eacute;e. Dans son projet, Marcela Fuentes &amp;eacute;tudie une prot&amp;eacute;ine nomm&amp;eacute;e Gex1 sans laquelle Leishmania est incapable de se reproduire. Envie de plonger dans les secrets de la s&amp;eacute;duction &amp;agrave; l&amp;rsquo;&amp;eacute;chelle microscopique&amp;#8239;? Vennez d&amp;eacute;couvrir comment ce parasite trouve (ou perd) l&amp;rsquo;amour&amp;#8239;!&lt;/p&gt;

&lt;p&gt;&lt;span style="font-size:22px"&gt;&lt;strong&gt;Savez-vous que le yaourt &amp;eacute;tait autrefois vendu en pharmacie ?&lt;/strong&gt;&lt;/span&gt;&lt;br /&gt;

Autrefois, les bact&amp;eacute;ries faisaient peur : on les accusait de nous empoisonner de l&amp;rsquo;int&amp;eacute;rieur. Aujourd&amp;rsquo;hui, on les mange sans h&amp;eacute;siter au petit-d&amp;eacute;jeuner. Que s&amp;rsquo;est-il pass&amp;eacute; entre les deux ?&lt;br /&gt;
Le talk d&amp;rsquo;Anne Hiol raconte comment le yaourt est pass&amp;eacute; du statut de rem&amp;egrave;de vendu en pharmacie &amp;agrave; celui d&amp;rsquo;aliment star, gr&amp;acirc;ce &amp;agrave; des scientifiques, des prix Nobel et quelques ferments lactiques. Apr&amp;egrave;s &amp;ccedil;a, vous ne regarderez plus jamais votre yaourt de la m&amp;ecirc;me fa&amp;ccedil;on&amp;hellip;.&lt;/p&gt;

Six intervenants ont anim&amp;eacute; ces rencontres autour de th&amp;eacute;matiques vari&amp;eacute;es telles que le cerveau, les tumeurs, les organes-sur-puce, le rein, le VIH, les organes perdus ou encore les cellules cili&amp;eacute;es.

Pr&amp;egrave;s de 120 participants ont assist&amp;eacute; aux pr&amp;eacute;sentations, rythm&amp;eacute;es par des quiz et m&amp;ecirc;me une chanson, dans une ambiance conviviale. L&amp;rsquo;&amp;eacute;valuation du public a &amp;eacute;t&amp;eacute; tr&amp;egrave;s positive, ce qui nous a encourag&amp;eacute;s &amp;agrave; renouveler l&amp;rsquo;exp&amp;eacute;rience en 2026.&lt;/p&gt;]]></content><enclosure url="https://www.fc3r.com/actualites/d/121-vignettepintofscience.jpg"  type="image/jpeg" lenght="960" /><image><title>Illustration</title><link>https://www.fc3r.com/actualites/d/121-vignettepintofscience.jpg</link><url>https://www.fc3r.com/actualites/d/121-vignettepintofscience.jpg</url><width>960</width></image></item><item><title>Clémence Deligne, lauréate du prix 3R « Recherche » 2025 du FC3R</title><link>https://www.fc3r.com/actualites/prix-3r-recherche-2025-fc3r-119.html</link><pubDate>05 Mar 2026</pubDate><description><![CDATA[Le FC3R a décerné le prix 3R Recherche 2025 à Clémence Deligne pour le développement d’une biobanque d’organoïdes destinée à l’étude et au traitement des cancers pédiatriques du cerveau.]]></description><content><![CDATA[&lt;h2&gt;FC3R&amp;nbsp;: Pouvez-vous vous pr&amp;eacute;senter&amp;nbsp;et nous parler de votre parcours&amp;nbsp;?&lt;/h2&gt;

&lt;p&gt;Je suis chercheuse post-doctorante au &lt;a href="https://www.crcl.fr/" target="_blank"&gt;Centre de Recherche en Canc&amp;eacute;rologie de Lyon&lt;/a&gt; (CRCL), sur le site du Centre L&amp;eacute;on B&amp;eacute;rard, dans l&amp;#39;&amp;eacute;quipe &amp;laquo;&amp;nbsp;&lt;a href="https://www.crcl.fr/equipes-de-recherche/mort-cellulaire-et-cancers-de-lenfant/" target="_blank"&gt;&amp;Eacute;tats cellulaires et cancers de l&amp;#39;enfant&amp;nbsp;&lt;/a&gt;&amp;raquo; codirig&amp;eacute;e par le Dr Marie Castets et le Pr Jean-Yves Blay. Nous travaillons sp&amp;eacute;cifiquement sur les cancers p&amp;eacute;diatriques, notamment les sarcomes et les tumeurs c&amp;eacute;r&amp;eacute;brales.&lt;/p&gt;

&lt;p&gt;Lors de mon doctorat au &lt;a href="http://lbhe.univ-artois.fr/" target="_blank"&gt;Laboratoire de la Barri&amp;egrave;re H&amp;eacute;mato-Enc&amp;eacute;phalique&lt;/a&gt; &amp;agrave; Lens, j&amp;rsquo;ai d&amp;eacute;velopp&amp;eacute; des mod&amp;egrave;les in vitro multicellulaires en 2D pour &amp;eacute;tudier les interactions entre les cellules de la barri&amp;egrave;re h&amp;eacute;mato-enc&amp;eacute;phalique et les cellules de gliome infiltrant du tronc c&amp;eacute;r&amp;eacute;bral, un cancer p&amp;eacute;diatrique tr&amp;egrave;s agressif plus commun&amp;eacute;ment appel&amp;eacute; par son acronyme anglais &amp;laquo;&amp;nbsp;DIPG&amp;nbsp;&amp;raquo;. J&amp;rsquo;ai ensuite voulu aller plus loin dans la mod&amp;eacute;lisation des tumeurs c&amp;eacute;r&amp;eacute;brales p&amp;eacute;diatriques en rejoignant le groupe du Dr Laura Broutier au CRCL pour mon postdoctorat. Je travaille depuis sur le d&amp;eacute;veloppement de mod&amp;egrave;les organo&amp;iuml;des tumoraux en 3D, aussi appel&amp;eacute;s tumoro&amp;iuml;des, de gliomes p&amp;eacute;diatriques de haut grade incluant les DIPG.&lt;/p&gt;

&lt;p&gt;Ces mod&amp;egrave;les tumoro&amp;iuml;des nous permettent d&amp;#39;appliquer le principe des 3R puisque nous n&amp;rsquo;utilisons pas l&amp;rsquo;animal pour mod&amp;eacute;liser et &amp;eacute;tudier ces tumeurs particuli&amp;egrave;res.&lt;/p&gt;

&lt;h2&gt;FC3R&amp;nbsp;: Pouvez-vous nous parler des travaux r&amp;eacute;compens&amp;eacute;s&amp;nbsp;?&lt;/h2&gt;

&lt;p&gt;Les cancers de l&amp;rsquo;enfant sont des tumeurs rares, environ 1 &amp;agrave; 2% seulement de tous les cancers. Ils repr&amp;eacute;sentent n&amp;eacute;anmoins la premi&amp;egrave;re cause de mortalit&amp;eacute; par maladie chez les enfants. Bien qu&amp;rsquo;on soigne d&amp;eacute;sormais jusqu&amp;rsquo;&amp;agrave; 80% des enfants atteints d&amp;rsquo;un cancer, soit quatre enfants sur cinq, certains cancers comme les gliomes de haut grade et les &amp;eacute;pendymomes de la fosse post&amp;eacute;rieure restent tr&amp;egrave;s difficiles &amp;agrave; &amp;eacute;radiquer.&lt;/p&gt;

&lt;p&gt;Cet &amp;eacute;chec th&amp;eacute;rapeutique provient en partie de l&amp;rsquo;h&amp;eacute;t&amp;eacute;rog&amp;eacute;n&amp;eacute;it&amp;eacute; de ces tumeurs. Il existe de multiples sous-types de gliomes de haut grade&amp;nbsp;: on parle d&amp;rsquo;h&amp;eacute;t&amp;eacute;rog&amp;eacute;n&amp;eacute;it&amp;eacute; inter-tumorale. Il existe de plus une h&amp;eacute;t&amp;eacute;rog&amp;eacute;n&amp;eacute;it&amp;eacute; dite intra-tumorale, c&amp;rsquo;est-&amp;agrave;-dire qu&amp;rsquo;il y a plusieurs populations de cellules &amp;agrave; l&amp;rsquo;int&amp;eacute;rieur m&amp;ecirc;me de la tumeur, et certaines populations vont &amp;ecirc;tre r&amp;eacute;sistantes aux traitements.&lt;/p&gt;

&lt;p&gt;C&amp;rsquo;est dans ce contexte, et sous l&amp;rsquo;impulsion de Laura Broutier et Arthur Tourbez, que nous avons d&amp;eacute;velopp&amp;eacute; des mod&amp;egrave;les tumoro&amp;iuml;des des tumeurs gliales p&amp;eacute;diatriques les plus l&amp;eacute;tales, c&amp;rsquo;est-&amp;agrave;-dire les gliomes p&amp;eacute;diatriques de haut grade, incluant les DIPG, et les &amp;eacute;pendymomes de la fosse post&amp;eacute;rieure. Les tumoro&amp;iuml;des sont des mini-r&amp;eacute;pliques&amp;nbsp;des tumeurs que nous g&amp;eacute;n&amp;eacute;rons in vitro en laboratoire. Ces mod&amp;egrave;les repr&amp;eacute;sentent fid&amp;egrave;lement l&amp;rsquo;h&amp;eacute;t&amp;eacute;rog&amp;eacute;n&amp;eacute;it&amp;eacute; des tumeurs d&amp;rsquo;origine, et nous permettent d&amp;rsquo;identifier quels traitements ou quelles combinaisons de traitements sont les plus efficaces contre ces tumeurs.&lt;/p&gt;

&lt;p&gt;J&amp;rsquo;en profite pour pr&amp;eacute;ciser que ces travaux repr&amp;eacute;sentent la collaboration de toute une &amp;eacute;quipe que je tiens &amp;agrave; remercier.&lt;/p&gt;

&lt;p&gt;&lt;img alt="" src="https://www.fc3r.com/actualites/d/119-actuprixrec2025.jpg" style="width:100%" /&gt;&lt;/p&gt;

&lt;h2&gt;FC3R&amp;nbsp;: Comment sont g&amp;eacute;n&amp;eacute;r&amp;eacute;s ces mod&amp;egrave;les organo&amp;iuml;des ? A partir de biopsies ou &amp;agrave; partir de cellules souches embryonnaires humaines&amp;nbsp;?&lt;/h2&gt;

&lt;p&gt;Nous collaborons avec des chirurgiens et des anatomopathologistes des &lt;a href="https://www.chu-lyon.fr/" target="_blank"&gt;Hospices Civils de Lyon&lt;/a&gt; qui nous donnent acc&amp;egrave;s &amp;agrave; des &amp;eacute;chantillons de biopsies et de r&amp;eacute;sections chirurgicales. M&amp;ecirc;me &amp;agrave; partir de petits fragments de tumeurs, nous r&amp;eacute;ussissons &amp;agrave; mettre en culture des mod&amp;egrave;les tumoro&amp;iuml;des gr&amp;acirc;ce aux protocoles que nous avons mis au point, et ainsi &amp;agrave; amplifier le mat&amp;eacute;riel de d&amp;eacute;part. Ces mod&amp;egrave;les peuvent &amp;ecirc;tre cultiv&amp;eacute;s de fa&amp;ccedil;on stable pendant des mois, voire des ann&amp;eacute;es, et peuvent &amp;ecirc;tre congel&amp;eacute;s et d&amp;eacute;congel&amp;eacute;s au besoin de nos projets.&lt;/p&gt;

&lt;h2&gt;FC3R&amp;nbsp;: On dit souvent que les organo&amp;iuml;des ne sont pas &amp;laquo;&amp;nbsp;matures&amp;nbsp;&amp;raquo; par rapport aux tissus d&amp;rsquo;origine chez l&amp;#39;adulte. Est-ce le cas de vos tumoro&amp;iuml;des&amp;nbsp;?&lt;/h2&gt;

&lt;p&gt;Nous avons fait une caract&amp;eacute;risation tr&amp;egrave;s compl&amp;egrave;te de nos mod&amp;egrave;les tumoro&amp;iuml;des au niveau histologique, transcriptomique, g&amp;eacute;nomique, &amp;eacute;pig&amp;eacute;nomique et fonctionnel. Cette caract&amp;eacute;risation exhaustive nous a permis de d&amp;eacute;montrer que nos mod&amp;egrave;les tumoro&amp;iuml;des reproduisaient fid&amp;egrave;lement les caract&amp;eacute;ristiques des tumeurs d&amp;rsquo;origine.&lt;/p&gt;

&lt;h2&gt;FC3R&amp;nbsp;: Il est souvent rapport&amp;eacute; que les tumeurs ne sont pas homog&amp;egrave;nes d&amp;rsquo;un point de vue cellulaire et m&amp;ecirc;me au niveau g&amp;eacute;n&amp;eacute;tique.&lt;/h2&gt;

&lt;p&gt;Effectivement les tumeurs ne sont pas constitu&amp;eacute;es d&amp;rsquo;une seule population de cellules mais de plusieurs populations cellulaires qui peuvent avoir des contenus g&amp;eacute;n&amp;eacute;tiques diff&amp;eacute;rents, en particulier des mutations g&amp;eacute;n&amp;eacute;tiques qui peuvent induire des r&amp;eacute;sistances. Nous avons d&amp;eacute;montr&amp;eacute; par targeted DNAseq et &amp;agrave; l&amp;rsquo;aide d&amp;rsquo;analyses bio-informatiques que l&amp;rsquo;on retrouvait bien les m&amp;ecirc;mes mutations clonales dans nos mod&amp;egrave;les que celles retrouv&amp;eacute;es dans les tumeurs d&amp;#39;origine, et ce dans des proportions similaires. Nous avons aussi v&amp;eacute;rifi&amp;eacute; la pr&amp;eacute;sence des diff&amp;eacute;rents &amp;eacute;tats cellulaires retrouv&amp;eacute;s dans des biopsies de gliomes de haut grade, gr&amp;acirc;ce &amp;agrave; la technique de single-cell RNAseq. C&amp;rsquo;est vraiment un des points forts de notre &amp;eacute;tude car l&amp;rsquo;h&amp;eacute;t&amp;eacute;rog&amp;eacute;n&amp;eacute;it&amp;eacute; intra-tumorale est source de r&amp;eacute;sistances aux traitements, il est donc essentiel de reproduire cette diversit&amp;eacute; dans nos mod&amp;egrave;les pour repr&amp;eacute;senter les m&amp;ecirc;mes m&amp;eacute;canismes de r&amp;eacute;sistance retrouv&amp;eacute;s chez les patients.&lt;/p&gt;

&lt;h2&gt;FC3R&amp;nbsp;: Les mod&amp;egrave;les in vitro &amp;agrave; partir de cellules humaines, organo&amp;iuml;des inclus, sont pertinents pour l&amp;rsquo;homme mais le sont-ils &amp;eacute;galement au niveau clinique ?&lt;/h2&gt;

&lt;p&gt;Effectivement le &amp;laquo;&amp;nbsp;clinically relevant&amp;nbsp;&amp;raquo; est un crit&amp;egrave;re essentiel pour les mod&amp;egrave;les utilis&amp;eacute;s en recherche translationnelle, afin de g&amp;eacute;n&amp;eacute;rer des r&amp;eacute;sultats robustes et transf&amp;eacute;rables &amp;laquo;&amp;nbsp;from bench to bedside&amp;nbsp;&amp;raquo;.&lt;/p&gt;

&lt;p&gt;Dans notre &amp;eacute;tude, nous avons &amp;eacute;tabli des mod&amp;egrave;les tumoro&amp;iuml;des avant et apr&amp;egrave;s la chimioth&amp;eacute;rapie chez deux patients. Nous avons ensuite expos&amp;eacute; ces tumoro&amp;iuml;des au m&amp;ecirc;me traitement re&amp;ccedil;u par le patient, et nous avons observ&amp;eacute; une r&amp;eacute;ponse in vitro qui reproduit la r&amp;eacute;ponse clinique. Nous avons ainsi pu d&amp;eacute;montrer le potentiel pr&amp;eacute;dictif et donc &amp;laquo;&amp;nbsp;clinically relevant&amp;nbsp;&amp;raquo; de nos mod&amp;egrave;les, qui est un grand point fort de notre &amp;eacute;tude et nous permet d&amp;rsquo;aller vers des perspectives de m&amp;eacute;decine personnalis&amp;eacute;e.&lt;/p&gt;

&lt;h2&gt;FC3R&amp;nbsp;: Comment appliquez-vous le principe des 3R dans vos recherches&amp;nbsp;?&lt;/h2&gt;

&lt;p&gt;La capacit&amp;eacute; de nos mod&amp;egrave;les tumoro&amp;iuml;des &amp;agrave; g&amp;eacute;n&amp;eacute;rer des r&amp;eacute;sultats suffisamment pertinents d&amp;rsquo;un point de vue clinique leur permettent de remplacer, au moins partiellement, les mod&amp;egrave;les animaux pour des &amp;eacute;tudes pr&amp;eacute;cliniques critiques, comme l&amp;rsquo;&amp;eacute;valuation de la r&amp;eacute;ponse aux m&amp;eacute;dicaments ou l&amp;rsquo;identification de m&amp;eacute;canismes de r&amp;eacute;sistance. De plus, en permettant une s&amp;eacute;lection in vitro des combinaisons th&amp;eacute;rapeutiques les plus prometteuses avant toute validation in vivo, nos mod&amp;egrave;les am&amp;eacute;liorent le bien-&amp;ecirc;tre animal en limitant leur exposition &amp;agrave; des protocoles exp&amp;eacute;rimentaux inefficaces ou invasifs.&lt;/p&gt;

&lt;h2&gt;FC3R&amp;nbsp;: Utilisez-vous une &amp;eacute;tape de &amp;laquo;&amp;nbsp;repiquage et amplification&amp;nbsp;&amp;raquo; chez des souris immunod&amp;eacute;ficientes&amp;nbsp;?&lt;/h2&gt;

&lt;p&gt;Nous, nous n&amp;rsquo;avons pas besoin de passer par cette &amp;eacute;tape. Gr&amp;acirc;ce au travail de mise au point du protocole de dissociation du tissu tumoral et du milieu de culture, nous r&amp;eacute;ussissons &amp;agrave; obtenir suffisamment de cellules viables qui prolif&amp;egrave;rent directement in vitro et conservent leurs caract&amp;eacute;ristiques d&amp;rsquo;origine. Cette m&amp;eacute;thode d&amp;rsquo;amplification directement in vitro nous permet d&amp;rsquo;&amp;eacute;viter de contaminer le mat&amp;eacute;riel humain avec des cellules murines, ce qui peut arriver lors de x&amp;eacute;nogreffes chez la souris.&lt;/p&gt;

&lt;h2&gt;FC3R&amp;nbsp;: Comment partagez-vous ces avanc&amp;eacute;es&amp;nbsp;?&lt;/h2&gt;

&lt;p&gt;Nous sommes en faveur d&amp;rsquo;une science ouverte et collaborative, permettant d&amp;rsquo;acc&amp;eacute;l&amp;eacute;rer la recherche en canc&amp;eacute;rologie p&amp;eacute;diatrique.&lt;/p&gt;

&lt;p&gt;Toutes nos donn&amp;eacute;es transcriptomiques et g&amp;eacute;nomiques sont disponibles en&amp;nbsp;&amp;laquo;&amp;nbsp;open access&amp;nbsp;&amp;raquo; sur le site du journal Neuro-Oncology. Nos donn&amp;eacute;es -omiques seront &amp;eacute;galement accessibles via la &lt;a href="https://www.ihope.fr/la-recherche/share4kids-un-entrepot-de-donnees-unique-en-france-sur-les-cancers-pediatriques/" target="_blank"&gt;plateforme Share4Kids&lt;/a&gt;, un entrep&amp;ocirc;t de donn&amp;eacute;es multi-omiques en canc&amp;eacute;rologie p&amp;eacute;diatrique partag&amp;eacute;es &amp;agrave; l&amp;rsquo;ensemble de la communaut&amp;eacute; scientifique Ce projet a &amp;eacute;t&amp;eacute; lanc&amp;eacute; par le Dr Marie Castets en 2018 et r&amp;eacute;compens&amp;eacute; par le prix Unicancer en 2023.&lt;/p&gt;

&lt;p&gt;Nos mod&amp;egrave;les sont aussi disponibles via Model4Kids, sous la forme de collaborations acad&amp;eacute;miques et industrielles, afin d&amp;rsquo;avancer dans la d&amp;eacute;couverte de m&amp;eacute;dicaments ou de combinaisons th&amp;eacute;rapeutiques plus efficaces et moins toxiques.&lt;/p&gt;

&lt;h2&gt;FC3R&amp;nbsp;: Et le futur&amp;nbsp;?&lt;/h2&gt;

&lt;p&gt;Nous souhaitons nous diriger vers la m&amp;eacute;decine personnalis&amp;eacute;e, en collaboration avec le Dr Pierre Leblond qui est m&amp;eacute;decin oncop&amp;eacute;diatre &amp;agrave; l&amp;rsquo;&lt;a href="https://www.ihope.fr/" target="_blank"&gt;IHOPe&lt;/a&gt;. En parall&amp;egrave;le du profilage mol&amp;eacute;culaire r&amp;eacute;alis&amp;eacute; en routine lors de la prise en charge d&amp;rsquo;un enfant atteint d&amp;rsquo;une tumeur c&amp;eacute;r&amp;eacute;brale, nous allons mettre en culture les cellules tumorales en laboratoire et tester diff&amp;eacute;rents m&amp;eacute;dicaments dans un d&amp;eacute;lai de 2 semaines pour savoir lesquels sont les plus efficaces in vitro. Nous obtenons ainsi rapidement une carte personnalis&amp;eacute;e des sensibilit&amp;eacute;s th&amp;eacute;rapeutiques qui indique au clinicien quels m&amp;eacute;dicaments ont le plus de chances de fonctionner pour chaque enfant, notamment en cas d&amp;#39;&amp;eacute;chec du premier traitement. Cette perspective permettrait &amp;eacute;galement d&amp;rsquo;&amp;eacute;liminer des traitements prescrits par habitude et qui seraient totalement inefficaces chez le patient, et ainsi lui &amp;eacute;viter d&amp;rsquo;&amp;ecirc;tre expos&amp;eacute; &amp;agrave; des toxicit&amp;eacute;s &amp;laquo;&amp;nbsp;inutiles&amp;nbsp;&amp;raquo;.&lt;/p&gt;

&lt;h2&gt;FC3R&amp;nbsp;: Que repr&amp;eacute;sente pour vous ce prix 3R &amp;laquo;&amp;nbsp;Recherche&amp;nbsp;&amp;raquo;&amp;nbsp;?&lt;/h2&gt;

&lt;p&gt;Je n&amp;rsquo;ai jamais travaill&amp;eacute; moi-m&amp;ecirc;me sur l&amp;rsquo;animal, que ce soit au cours de ma th&amp;egrave;se ou de mon postdoctorat. J&amp;rsquo;ai toujours eu &amp;agrave; c&amp;oelig;ur de contribuer au d&amp;eacute;veloppement de mod&amp;egrave;les in vitro de plus en plus complexes, et je reste fascin&amp;eacute;e des progr&amp;egrave;s technologiques r&amp;eacute;alis&amp;eacute;s pour repr&amp;eacute;senter de mieux en mieux les tissus sains et tumoraux in vitro en incorporant leurs microenvironnements. Cr&amp;eacute;er ce pont entre les mod&amp;egrave;les animaux et les mod&amp;egrave;les organo&amp;iuml;des est important. Je ne dis pas que l&amp;#39;on pourra totalement remplacer les mod&amp;egrave;les animaux, mais nous pouvons les limiter consid&amp;eacute;rablement en les r&amp;eacute;servant &amp;agrave; des &amp;eacute;tudes pr&amp;eacute;cliniques plus tardives. Ce prix 3R repr&amp;eacute;sente donc une reconnaissance de ces efforts pour d&amp;eacute;velopper des mod&amp;egrave;les pr&amp;eacute;cliniques plus &amp;eacute;thiques, et potentiellement plus pr&amp;eacute;dictifs, pour acc&amp;eacute;l&amp;eacute;rer dans la d&amp;eacute;couverte de traitements plus efficaces et moins toxiques en canc&amp;eacute;rologie p&amp;eacute;diatrique.&lt;/p&gt;]]></content><enclosure url="https://www.fc3r.com/actualites/d/119-actuprixrec2025.jpg"  type="image/jpeg" lenght="960" /><image><title>Illustration</title><link>https://www.fc3r.com/actualites/d/119-actuprixrec2025.jpg</link><url>https://www.fc3r.com/actualites/d/119-actuprixrec2025.jpg</url><width>960</width></image></item><item><title>Candice Hackney: winner of the FC3R 2025 3Rs Culture of Care Award</title><link>https://www.fc3r.com/actualites/fc3r-2025-3rs-culture-of-care-award-118.html</link><pubDate>12 Jan 2026</pubDate><description><![CDATA[Candice Hackney was awarded the 2025 'Culture of Care' Prize by the FC3R for her project, 'Impacts of rodent handling techniques on their welfare and reproductive parameters'.]]></description><content><![CDATA[&lt;h2&gt;Could you introduce yourself and tell us about your background?&lt;/h2&gt;

&lt;p&gt;I am an assistant engineer, the head of the or SBEA (Animal Welfare Body) and a member of an Comit&amp;eacute;s d&amp;#39;&amp;eacute;thique en exp&amp;eacute;rimentation animale or CEEA (animal experimentation ethics committees). I co-lead the &amp;#39;Ethics and Welfare&amp;#39; group, and I am also a member of the &amp;#39;Transgenesis&amp;#39; group within &lt;a href="https://celphedia.eu/en/" target="_blank"&gt;the national research infrastructure Celphedia&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;I have over 24 years&amp;#39; experience in animal experimentation. I began my career as a junior employee at the Faculty of Medicine in Rouen. After passing the CNRS external competitive examinations, I worked as a breeding technician at the &lt;a href="https://www.taam.cnrs.fr/" target="_blank"&gt;Animal Model Typing and Archiving Support and Research Unit (UAR TAAM)&lt;/a&gt; in Orl&amp;eacute;ans and at the &lt;a href="https://www.primato.cnrs.fr/" target="_blank"&gt;Rousset primatology station&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Since 2017, I have worked as a technician and subsequently as an assistant engineer at the &lt;a href="https://htag.univ-grenoble-alpes.fr/" target="_blank"&gt;hTAG Support and Research Unit&lt;/a&gt; in Grenoble.&lt;/p&gt;

&lt;p&gt;I have long been committed to the welfare of various animal species, I would like to thank all the organisations and animal facility managers who have enabled me to discover the richness and diversity of this field, and to cultivate my passion for it.&lt;/p&gt;

&lt;h2&gt;Please tell us about the 3Rs and the culture of care in your laboratory on a daily basis?&lt;/h2&gt;

&lt;p&gt;Since becoming an SBEA manager in 2022, I have initiated and supported numerous changes to practices and attitudes, with the aim of promoting a more respectful approach to animal welfare.&lt;/p&gt;

&lt;p&gt;These changes include:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;
	&lt;p&gt;replacing the use of forceps to restrain animals with more humane methods, such as cupping, using tunnels or restraining them by the scruff of their neck when necessary;&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;abandoning phalangectomy in favour of tattooing the phalanges for animal identification;&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;implementing training courses, including those outside my own establishment, to disseminate these good practices.I have also introduced new methods and enrichment activities, including three-finger restraint, creating &amp;quot;play areas&amp;quot; for rats and developing and structuring tickling practices.&lt;/p&gt;
	&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Studies have shown that two-finger restraint creates a longitudinal skin fold, stretching the skin around the throat and trachea. This causes stress to the animal and severe bradyarrhythmias that persist for four minutes after release. In line with &lt;a href="https://norecopa.no/education-training/films-and-slide-shows/refined-technique-for-scruffing-animals" target="_blank"&gt;Norecopa&amp;#39;s&lt;/a&gt; recommendations, we adopted three-finger restraint and introduced this technique across the entire animal facility.&lt;/p&gt;

&lt;p&gt;&lt;img alt="" src="https://www.fc3r.com/actualites/d/118-actuprixsoin25fig2-eng.png" style="width:80%" /&gt;&lt;br /&gt;
&lt;br /&gt;
During playtime and &lt;a href="http://nc3rs.org.uk/3rs-resources/rat-tickling" target="_blank"&gt;tickling sessions&lt;/a&gt;, the rats are placed in a transfer isolator containing various items for them to discover and explore, such as tubes, houses, grids and crimped wire, as well as a cage filled with water. After a few minutes, the animal technician begins to interact with the rats using their hands and proceeds to &amp;#39;tickle&amp;#39; them. This technique comprises three main elements: &amp;#39;dorsal contact&amp;#39; on the rat&amp;#39;s neck; a &amp;#39;pinch&amp;#39; on the rat&amp;#39;s belly; and &amp;#39;tickling&amp;#39;. In the Panksepp method, 15 seconds of hand contact is alternated with 15 seconds of no contact, for a total of two minutes.&lt;/p&gt;

&lt;p&gt;&lt;img alt="" src="https://www.fc3r.com/actualites/d/118-actuprixsoin25fig2-2-eng.png" style="width:100%" /&gt;&lt;/p&gt;

&lt;p&gt;My commitment is unwavering. I am always thinking of new ways to improve the application of the 3Rs, enhance animal welfare, and develop enrichment practices within teams.&lt;/p&gt;

&lt;h2&gt;How can these advances be shared with the scientific community?&lt;/h2&gt;

&lt;p&gt;I recently gave a presentation on best practices in animal experimentation to medical students, together with our organisation&amp;#39;s veterinary consultant, Mr Bertrand Favier.&lt;/p&gt;

&lt;p&gt;In 2024, I provided tattooing training to several teams at various animal facilities in Grenoble, and delivered a presentation on rodent handling methods as part of the Designer-level training course.&lt;/p&gt;

&lt;p&gt;Although I am rather reserved by nature, I am nevertheless committed to changing attitudes. With this in mind, I joined the Celphedia working group, where I met other professionals who were eager to discuss innovative techniques.&lt;/p&gt;

&lt;p&gt;In 2025, I presented the &amp;#39;Tickling&amp;#39; method at the AFSTAL conference. Eager to maintain this momentum, I am fully committed to my ethics and animal welfare working group. We responded to a call for tenders and obtained Celphedia&amp;#39;s support for the &amp;#39;Tickling&amp;#39; project. I am currently awaiting the results of the FC3R Refinement call for tenders, for which I submitted a project.&lt;/p&gt;

&lt;p&gt;I have also been asked to write an article for the STAL scientific journal in 2026. I plan to submit a short paper to AFSTAL 2026, and I have also been invited to present my work at the Grenoble Animal Facilities Group conference.&lt;/p&gt;

&lt;p&gt;My main goal is to disseminate these techniques on a national scale and make a lasting impression on the people I have met while working in the field of animal welfare. The positive feedback I receive is a real source of motivation and satisfaction.&lt;/p&gt;

&lt;h2&gt;What does the 3R &amp;#39;Culture of Care&amp;#39; Award mean to you?&lt;/h2&gt;

&lt;p&gt;Winning this award would strongly recognise my daily commitment to animal welfare and the culture of care. Despite the constant involvement it requires, this work is still too often invisible and insufficiently valued.&lt;/p&gt;

&lt;p&gt;For several years, I have been thinking constantly about how to make concrete improvements at the grassroots level to change practices and attitudes. My drive for continuous improvement is deeply ingrained.&lt;/p&gt;

&lt;p&gt;As a former high-level competitor, I developed discipline and mental strength, and these qualities have always accompanied me, driving me to strive for excellence and achieve my goals. This is particularly true with regard to the evolution of professional practices and the dissemination of a demanding yet respectful culture of care.&lt;/p&gt;

&lt;p&gt;I am deeply passionate about my work and animal behaviour, particularly that of non-human primates. I would like to thank the managers and colleagues who have supported me throughout my career, during which time I have remained driven by my passion and desire to progress and share my knowledge.&lt;/p&gt;]]></content><enclosure url="https://www.fc3r.com/actualites/d/118-actuprixsoin25fig2-eng.png"  type="image/jpeg" lenght="960" /><image><title>Illustration</title><link>https://www.fc3r.com/actualites/d/118-actuprixsoin25fig2-eng.png</link><url>https://www.fc3r.com/actualites/d/118-actuprixsoin25fig2-eng.png</url><width>960</width></image></item><item><title>Ethi.3R: A national project that aims to harmonise the expertise of members of animal experimentation ethics committees</title><link>https://www.fc3r.com/actualites/ethi.3r-harmonising-the-expertise-of-members-of-117.html</link><pubDate>12 Jan 2026</pubDate><description><![CDATA[Ethi3R, national training project for members of animal experimentation ethics committees, has been a marked success since its first sessions.]]></description><content><![CDATA[&lt;p&gt;The first FC3R call for projects, &amp;quot;&lt;a href="https://www.fc3r.com/en/laureates-3R-in-France-1-2022.html" target="_blank"&gt;The 3Rs in France: Collective Initiatives and Sharing Tools&lt;/a&gt;&amp;quot;, aimed to fund projects to reduce, replace or refine the use of animals in laboratories by developing collaborative and structured tools. This call generated considerable interest, with 51 projects being submitted. &lt;a href="https://prelude.unicaen.fr/course/index.php?categoryid=52&amp;amp;lang=en" target="_blank"&gt;&lt;strong&gt;Ethi.3R &lt;/strong&gt;&lt;/a&gt;was one of the seven winning projects, standing out for the clarity of its approach to harmonising the training of members of Comit&amp;eacute;s d&amp;#39;&amp;eacute;thique en exp&amp;eacute;rimentation animale or CEEAs (animal experimentation ethics committees)&lt;/p&gt;

&lt;h2&gt;Across the country, and for the soundness of its implementation.&lt;/h2&gt;

&lt;p&gt;The CEAs play a central role as regulatory bodies, reviewing scientific projects involving the use of animals and ensuring compliance with regulations and adherence to the 3Rs principle (Replace, Reduce, Refine). Currently, &lt;a href="http://www.enseignementsup-recherche.gouv.fr/sites/default/files/2025-07/bilan-annuel-national-d-activit-des-comit-s-d-thique-en-exp-rimentation-animale-ceea-ann-e-2024--37548.pdf" target="_blank"&gt;76 ethics committees&lt;/a&gt; operating across France in various scientific, institutional and organisational contexts. Given this diversity, the need for national harmonisation of practices has become apparent over the years. To address this collective challenge, the committees have formed a &lt;a href="http://sbea-c2ea.fr/c2ea/le-reseau/" target="_blank"&gt;national network&lt;/a&gt; dedicated to sharing best practice and pooling assessment tools.&lt;/p&gt;

&lt;table border="0" cellpadding="10" cellspacing="1" style="width:100%"&gt;
	&lt;tbody&gt;
		&lt;tr&gt;
			&lt;td&gt;
			&lt;p&gt;The Ethi.3R project aimed &lt;strong&gt;to reinforce this dynamic&lt;/strong&gt; by proposing a significant advancement in the &lt;strong&gt;harmonisation of CEEA member training&lt;/strong&gt;: the development of a free SPOC accessible to all CEEAs members. This original initiative was led by three members with complementary profiles: Valentine Bouet (university professor at UniCaen and chair of ethics committee No. 54), Laura Barrot (Inserm research engineer and member of ethics committees Nos. 10 and 42), and Laurent Chazalviel (CNRS research engineer and deputy chair of ethics committee No. 54).&lt;/p&gt;
			&lt;/td&gt;
			&lt;td style="width:50%"&gt;
			&lt;p&gt;&lt;img alt="" src="https://www.fc3r.com/actualites/d/115-actuethi3r.jpg" style="margin-left:2px;margin-right:2px;width:100%" /&gt;&lt;/p&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
	&lt;/tbody&gt;
&lt;/table&gt;

&lt;p&gt;Thanks to &amp;euro;45,576 in funding from FC3R in 2022, the Ethi.3R project has developed &lt;strong&gt;a training course comprising four complementary modules&lt;/strong&gt;.&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;
	&lt;p&gt;&lt;strong&gt;Ethical considerations&amp;nbsp;&lt;/strong&gt;(Module 1 compulsory).&lt;strong&gt;&amp;nbsp;&lt;/strong&gt;This module covers the relationship between researchers and animals, the history of animal protection, the practical application of ethical principles, communication on animal research and limit points.&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;&lt;strong&gt;The regulatory framework &lt;/strong&gt;(Module 2 compulsory). This focuses on legal obligations, experimental procedures, the severity of procedures, and retrospective assessments.&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;&lt;strong&gt;How to Evaluate a Project Authorisation Request &lt;/strong&gt;(Module 3, Optional).&amp;nbsp;This module focuses on the practical application of ethical evaluation, which is a key stage in the work of the committees.&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;&lt;strong&gt;Statistics &lt;/strong&gt;(Module 4 non-compulsory)&lt;strong&gt;&amp;nbsp;&lt;/strong&gt;aimed at strengthening understanding of statistical tests and experimental design.&lt;br /&gt;
	&amp;nbsp;&lt;/p&gt;
	&lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;A first positive assessment&lt;/h2&gt;

&lt;p&gt;The first training session, held between May and August 2025, attracted 587 participants. At the end of the session, 404 certificates of completion were issued, representing around 18% of C2EA members who have been trained at a national level. Participation and quiz completion rates were high, and the level of satisfaction among participants was high.&lt;/p&gt;

&lt;p&gt;A second session, organised from October to December 2025, saw 606 participants register, confirming this enthusiasm. This new session introduced several improvements, including simplified access to the platform, improved quiz questions, downloadable documents and clearer information on certificates.&lt;/p&gt;

&lt;p&gt;To date, Ethi.3R has trained almost 34% of the 2,200 members of ethics committees.&lt;/p&gt;

&lt;h2&gt;The Future of Ethi.3R&lt;/h2&gt;

&lt;p&gt;For its developers, the greatest success for Ethi.3R in five years&amp;#39; time would be if all members of French ethics committees had completed this training, and if all new members were trained on Ethi.3R in addition to the other available training courses (Gircor, Charles River and e-thiX) as soon as they joined a committee. The AfiS unit could then include these figures in committee audits and promote them to the European Commission. The developers also hope that the training programme will expand, particularly in other French-speaking European countries that could benefit from it.&lt;/p&gt;]]></content><enclosure url="https://www.fc3r.com/actualites/d/117-vignetteethi3r2.png"  type="image/jpeg" lenght="960" /><image><title>Illustration</title><link>https://www.fc3r.com/actualites/d/117-vignetteethi3r2.png</link><url>https://www.fc3r.com/actualites/d/117-vignetteethi3r2.png</url><width>960</width></image></item><item><title>Candice Hackney, lauréate du prix 3R "Culture du soin" 2025 du FC3R</title><link>https://www.fc3r.com/actualites/prix-3r-culture-soin-2025-fc3r-116.html</link><pubDate>08 Jan 2026</pubDate><description><![CDATA[Le FC3R a remis le prix 3R "Culture du soin" 2025 à Candice Hackney pour son projet « Impacts des techniques de manipulation des rongeurs sur leur bien-être et les paramètres de reproduction ».]]></description><content><![CDATA[&lt;h2&gt;Pouvez-vous vous pr&amp;eacute;senter et nous parler de votre parcours ?&lt;/h2&gt;

&lt;p&gt;Je suis assistante ing&amp;eacute;nieure et responsable SBEA (Structure charg&amp;eacute;e du Bien-&amp;Ecirc;tre Animal), ainsi que membre d&amp;rsquo;un comit&amp;eacute; d&amp;rsquo;&amp;eacute;thique. Je co-pilote &amp;eacute;galement le groupe &amp;laquo; &amp;Eacute;thique et bien-&amp;ecirc;tre &amp;raquo; et je suis membre du groupe &amp;laquo; Transg&amp;eacute;n&amp;egrave;se &amp;raquo; de &lt;a href="https://celphedia.eu/en/" target="_blank"&gt;l&amp;rsquo;infrastructure nationale de recherche Celphedia&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Avec plus de 24 ans d&amp;rsquo;exp&amp;eacute;rience dans le domaine de l&amp;rsquo;exp&amp;eacute;rimentation animale, j&amp;rsquo;ai d&amp;eacute;but&amp;eacute; comme emploi jeune &amp;agrave; la facult&amp;eacute; de m&amp;eacute;decine de Rouen. J&amp;rsquo;ai ensuite r&amp;eacute;ussi les concours externes du CNRS et exerc&amp;eacute; en tant que technicienne en &amp;eacute;levage au sein de &lt;a href="https://www.taam.cnrs.fr/" target="_blank"&gt;l&amp;rsquo;Unit&amp;eacute; d&amp;rsquo;Appui et de Recherche Typage et Archivage d&amp;#39;Animaux Mod&amp;egrave;les d&amp;rsquo;Orl&amp;eacute;ans&lt;/a&gt; (UAR TAAM), puis &amp;agrave; la &lt;a href="https://www.primato.cnrs.fr/" target="_blank"&gt;station de primatologie de Rousset&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Depuis 2017, j&amp;rsquo;exerce en tant que technicienne puis assistante ing&amp;eacute;nieure au sein de &lt;a href="https://htag.univ-grenoble-alpes.fr/" target="_blank"&gt;l&amp;rsquo;Unit&amp;eacute; d&amp;rsquo;Appui et de Recherche hTAG de Grenoble&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Engag&amp;eacute;e de longue date en faveur du bien-&amp;ecirc;tre animal aupr&amp;egrave;s de diverses esp&amp;egrave;ces, je tiens &amp;agrave; remercier l&amp;rsquo;ensemble des structures et responsables d&amp;rsquo;animalerie qui m&amp;rsquo;ont permis de d&amp;eacute;couvrir la richesse et la diversit&amp;eacute; de ce domaine et de cultiver cette passion.&lt;/p&gt;

&lt;h2&gt;Parlez-nous des 3R et de la culture du soin au quotidien dans votre laboratoire&amp;nbsp;?&lt;/h2&gt;

&lt;p&gt;Depuis que je suis responsable SBEA en 2022, j&amp;rsquo;ai initi&amp;eacute; et accompagn&amp;eacute; de nombreux changements de pratiques et de mentalit&amp;eacute;s pour promouvoir une approche plus respectueuse du bien-&amp;ecirc;tre animal.&lt;br /&gt;
&lt;br /&gt;
Parmi ces &amp;eacute;volutions, on peut citer :&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;
	&lt;p&gt;le remplacement de la prise des animaux &amp;agrave; la pince par des m&amp;eacute;thodes plus respectueuses telles que le &amp;laquo;&amp;nbsp;cupping&amp;nbsp;&amp;raquo;, l&amp;rsquo;utilisation de tunnels ou, lorsque n&amp;eacute;cessaire, la prise par la peau du cou ;&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;l&amp;rsquo;abandon de la phalangectomie au profit du tatouage des phalanges pour l&amp;rsquo;identification des animaux;&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;la mise en place de formations, y compris en dehors de mon &amp;eacute;tablissement, afin de diffuser ces&amp;nbsp;bonnes pratiques.&lt;/p&gt;
	&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;br /&gt;
J&amp;rsquo;ai aussi introduit de nouvelles m&amp;eacute;thodes et enrichissements, notamment : la contention &amp;agrave; trois doigts, la mise en place de &amp;laquo; cours de r&amp;eacute;cr&amp;eacute;ation &amp;raquo; pour les rats, le d&amp;eacute;veloppement et la structuration de la pratique du tickling.&lt;/p&gt;

&lt;p&gt;Pour la contention, des &amp;eacute;tudes ont montr&amp;eacute;s que la contention &amp;agrave; deux doigts, cela a tendance &amp;agrave; cr&amp;eacute;er un pli cutan&amp;eacute; longitudinal qui peut tendre la peau au niveau de la gorge et de la trach&amp;eacute;e, provoquant ainsi du stress chez l&amp;rsquo;animal, des bradyarythmies s&amp;eacute;v&amp;egrave;res qui ont persist&amp;eacute; 4 minutes apr&amp;egrave;s la lib&amp;eacute;ration des souris. Nous avons suivi les recommandations de &lt;a href="https://norecopa.no/education-training/films-and-slide-shows/refined-technique-for-scruffing-animals" target="_blank"&gt;Norecopa&lt;/a&gt; en utilisant une contention &amp;agrave; trois doigts, et mis en place cette technique dans toutes les zones de l&amp;rsquo;animalerie.&lt;/p&gt;

&lt;p&gt;&lt;img alt="" src="https://www.fc3r.com/actualites/d/116-actuprixsoin25fig1-2.png" style="width:80%" /&gt;&lt;/p&gt;

&lt;p&gt;Pour la cour de r&amp;eacute;cr&amp;eacute;ation et &lt;a href="https://nc3rs.org.uk/3rs-resources/rat-tickling" target="_blank"&gt;le tickling des rats&lt;/a&gt;, les animaux sont plac&amp;eacute;s dans un isolateur de transfert contenant diff&amp;eacute;rents &amp;eacute;l&amp;eacute;ments &amp;agrave; d&amp;eacute;couvrir, explorer (tube, maisons, grille, frisure, cage remplie d&amp;#39;eau). Apr&amp;egrave;s quelques minutes, le zootechnicien commence aussi quelques mouvements d&amp;rsquo;interaction avec les animaux en utilisant ses mains, puis proc&amp;egrave;de &amp;agrave; un &amp;laquo; tickling &amp;raquo; (chatouillement). La technique comprend trois &amp;eacute;l&amp;eacute;ments principaux, un &amp;laquo; contact dorsal &amp;raquo; sur le cou du rat et une &amp;laquo; &amp;eacute;pingle &amp;raquo; sur le ventre du rat puis des &amp;laquo; chatouillements &amp;raquo;. Nous alternons 15 secondes de contact de la main et 15 sec de sortie de contact pour un total de 2 minutes (m&amp;eacute;thode Panksepp).&lt;/p&gt;

&lt;p&gt;&lt;img alt="" src="https://www.fc3r.com/actualites/d/116-actuprixsoin25fig2-2.png" style="width:100%" /&gt;&lt;/p&gt;

&lt;p&gt;Mon engagement est constant : je r&amp;eacute;fl&amp;eacute;chis en permanence &amp;agrave; de nouvelles pistes pour am&amp;eacute;liorer l&amp;rsquo;application des 3R, renforcer le bien-&amp;ecirc;tre animal et faire &amp;eacute;voluer les enrichissements et les pratiques au sein des &amp;eacute;quipes.&lt;/p&gt;

&lt;h2&gt;Comment partagez-vous ces avanc&amp;eacute;es&amp;nbsp;avec la communaut&amp;eacute; scientifique&amp;nbsp;?&lt;/h2&gt;

&lt;p&gt;Je suis intervenue, avec le v&amp;eacute;t&amp;eacute;rinaire r&amp;eacute;f&amp;eacute;rent de notre structure, M. Bertrand Favier, aupr&amp;egrave;s d&amp;rsquo;&amp;eacute;tudiants en m&amp;eacute;decine afin de leur pr&amp;eacute;senter les bonnes pratiques en exp&amp;eacute;rimentation animale.&lt;/p&gt;

&lt;p&gt;En 2024, j&amp;rsquo;ai form&amp;eacute; plusieurs &amp;eacute;quipes au tatouage dans diff&amp;eacute;rentes animaleries grenobloises, puis j&amp;rsquo;ai r&amp;eacute;alis&amp;eacute; une pr&amp;eacute;sentation sur les m&amp;eacute;thodes de manipulation des rongeurs dans le cadre de la formation niveau Concepteur.&lt;/p&gt;

&lt;p&gt;De nature plut&amp;ocirc;t r&amp;eacute;serv&amp;eacute;e, j&amp;rsquo;ai n&amp;eacute;anmoins &amp;agrave; c&amp;oelig;ur de faire &amp;eacute;voluer les mentalit&amp;eacute;s. C&amp;rsquo;est dans cette optique que je me suis engag&amp;eacute;e dans l&amp;rsquo;aventure du groupe de travail Celphedia, qui m&amp;rsquo;a permis de rencontrer d&amp;rsquo;autres professionnels motiv&amp;eacute;s et d&amp;eacute;sireux d&amp;rsquo;&amp;eacute;changer autour de techniques innovantes.&lt;/p&gt;

&lt;p&gt;Toujours en 2025, j&amp;rsquo;ai pr&amp;eacute;sent&amp;eacute; la m&amp;eacute;thode du &amp;laquo;&amp;nbsp;Tickling&amp;nbsp;&amp;raquo; lors du colloque AFSTAL. Souhaitant poursuivre cette dynamique, je m&amp;rsquo;investis pleinement au sein de mon groupe de travail &amp;eacute;thique et bien-&amp;ecirc;tre animal. Nous avons r&amp;eacute;pondu &amp;agrave; un appel d&amp;rsquo;offres et obtenu le soutien de Celphedia pour le projet Tickling.&lt;/p&gt;

&lt;p&gt;Je suis actuellement en attente des r&amp;eacute;sultats de l&amp;rsquo;appel d&amp;rsquo;offres Raffinement du FC3R pour lequel j&amp;rsquo;ai d&amp;eacute;pos&amp;eacute; un projet.&lt;br /&gt;
Pour 2026, j&amp;rsquo;ai &amp;eacute;t&amp;eacute; sollicit&amp;eacute;e pour r&amp;eacute;diger un article dans la revue scientifique STAL. Je pr&amp;eacute;vois &amp;eacute;galement de proposer une communication courte pour l&amp;rsquo;AFSTAL 2026, et j&amp;rsquo;ai &amp;eacute;t&amp;eacute; invit&amp;eacute;e &amp;agrave; pr&amp;eacute;senter mes travaux lors du colloque du Groupement des Animaleries de Grenoble.&lt;br /&gt;
&lt;br /&gt;
Mon objectif est avant tout de diffuser ces techniques &amp;agrave; l&amp;rsquo;&amp;eacute;chelle nationale et de laisser, aupr&amp;egrave;s des personnes que j&amp;rsquo;ai rencontr&amp;eacute;es, une empreinte durable au service du bien-&amp;ecirc;tre animal. Les retours positifs que je re&amp;ccedil;ois sont une v&amp;eacute;ritable source de motivation et de satisfaction.&lt;/p&gt;

&lt;h2&gt;Que repr&amp;eacute;sente pour vous ce prix 3R Culture du soin&amp;nbsp;?&lt;/h2&gt;

&lt;p&gt;L&amp;rsquo;obtention de ce prix est avant tout une reconnaissance forte de mon engagement quotidien en faveur du bien-&amp;ecirc;tre animal et de la culture du soin, un travail qui reste encore trop souvent peu visible et insuffisamment valoris&amp;eacute; malgr&amp;eacute; l&amp;rsquo;implication constante qu&amp;rsquo;il exige.&lt;br /&gt;
&lt;br /&gt;
Depuis plusieurs ann&amp;eacute;es, je ne me lasse pas de r&amp;eacute;fl&amp;eacute;chir &amp;agrave; des am&amp;eacute;liorations concr&amp;egrave;tes, men&amp;eacute;es au plus pr&amp;egrave;s du terrain, afin de faire &amp;eacute;voluer les pratiques et les mentalit&amp;eacute;s. Cette dynamique d&amp;rsquo;am&amp;eacute;lioration continue est profond&amp;eacute;ment ancr&amp;eacute;e en moi.&lt;br /&gt;
&lt;br /&gt;
Ancienne comp&amp;eacute;titrice de haut niveau, j&amp;rsquo;ai d&amp;eacute;velopp&amp;eacute; une rigueur et une force mentale qui m&amp;rsquo;ont toujours accompagn&amp;eacute;e et qui me poussent encore aujourd&amp;rsquo;hui &amp;agrave; donner le meilleur de moi-m&amp;ecirc;me pour atteindre mes objectifs, notamment en ce qui concerne l&amp;rsquo;&amp;eacute;volution des pratiques professionnelles et la diffusion d&amp;rsquo;une culture du soin exigeante et respectueuse.&lt;br /&gt;
&lt;br /&gt;
Je suis profond&amp;eacute;ment passionn&amp;eacute;e par mon m&amp;eacute;tier, par le comportement animal et plus particuli&amp;egrave;rement par les primates non humains. Je remercie sinc&amp;egrave;rement les responsables et coll&amp;egrave;gues qui m&amp;rsquo;ont accompagn&amp;eacute;e et soutenue tout au long de ce parcours, tout en restant anim&amp;eacute;e par cette passion et cette volont&amp;eacute; constante de progresser et de transmettre.&lt;/p&gt;]]></content><enclosure url="https://www.fc3r.com/actualites/d/116-actuprixsoin25fig2-2.png"  type="image/jpeg" lenght="960" /><image><title>Illustration</title><link>https://www.fc3r.com/actualites/d/116-actuprixsoin25fig2-2.png</link><url>https://www.fc3r.com/actualites/d/116-actuprixsoin25fig2-2.png</url><width>960</width></image></item><item><title>Ethi.3R : projet national pour harmoniser l’expertise des membres des comités d’éthique en expérimentation animale</title><link>https://www.fc3r.com/actualites/ethi.3r-harmoniser-expertise-membres-comites-d-ethique-115.html</link><pubDate>30 Dec 2025</pubDate><description><![CDATA[Ethi3R, projet national de formation des membres de comités d’éthique en expérimentation animale, connaît un succès marqué dès ses premières sessions.]]></description><content><![CDATA[&lt;p&gt;Ce premier appel &amp;agrave; projets du FC3R, &amp;laquo; &lt;a href="https://www.fc3r.com/laureats-3R-en-France-1-2022.html" target="_blank"&gt;Les 3R en France : Initiatives collectives et outils de partage&lt;/a&gt; &amp;raquo;, destin&amp;eacute; &amp;agrave; financer des actions visant &amp;agrave; r&amp;eacute;duire, remplacer ou raffiner l&amp;rsquo;utilisation des animaux dans les laboratoires gr&amp;acirc;ce au d&amp;eacute;veloppement d&amp;rsquo;outils structurants et collaboratifs, avait suscit&amp;eacute; un vif engouement, avec 51 projets soumis.

&lt;h2&gt;Ethi.3R : harmoniser&amp;nbsp;l&amp;rsquo;&amp;eacute;thique, &amp;agrave; l&amp;rsquo;&amp;eacute;chelle nationale&lt;/h2&gt;

&lt;p&gt;Les CEEA jouent un r&amp;ocirc;le central : structures r&amp;eacute;glementaires, ils sont charg&amp;eacute;s d&amp;rsquo;examiner les projets scientifiques n&amp;eacute;cessitant le recours aux animaux, en veillant &amp;agrave; la conformit&amp;eacute; r&amp;eacute;glementaire et au respect du principe des 3R (Remplacer, R&amp;eacute;duire, Raffiner). Aujourd&amp;rsquo;hui, la France compte&lt;a href="https://www.enseignementsup-recherche.gouv.fr/sites/default/files/2025-07/bilan-annuel-national-d-activit-des-comit-s-d-thique-en-exp-rimentation-animale-ceea-ann-e-2024--37548.pdf" target="_blank"&gt; 76 comit&amp;eacute;s d&amp;rsquo;&amp;eacute;thique&lt;/a&gt;, r&amp;eacute;partis sur l&amp;rsquo;ensemble du territoire et intervenant dans des contextes scientifiques, institutionnels et organisationnels divers.

Pour r&amp;eacute;pondre &amp;agrave; cet enjeu collectif, les comit&amp;eacute;s ont cr&amp;eacute;&amp;eacute; le &lt;a href="https://sbea-c2ea.fr/c2ea/le-reseau/" target="_blank"&gt;r&amp;eacute;seau national des comit&amp;eacute;s d&amp;rsquo;&amp;eacute;thique CEEA&lt;/a&gt;, d&amp;eacute;di&amp;eacute; au partage des bonnes pratiques et &amp;agrave; la mutualisation d&amp;rsquo;outils d&amp;rsquo;&amp;eacute;valuation.&lt;/p&gt;

			&lt;p&gt;Le projet Ethi.3R avait pour objectif de &lt;strong&gt;renforcer cette dynamique&lt;/strong&gt; en proposant une avanc&amp;eacute;e majeure pour &lt;strong&gt;&amp;laquo;&amp;nbsp;harmoniser&amp;nbsp;&amp;raquo; la formation des membres des CEEA&lt;/strong&gt; : le d&amp;eacute;veloppement d&amp;rsquo;un SPOC gratuit et accessible &amp;agrave; tous les membres des CEEA. Cette initiative originale a &amp;eacute;t&amp;eacute; port&amp;eacute;e par trois membres aux profils compl&amp;eacute;mentaires - Valentine Bouet (Professeure des universit&amp;eacute;s, UniCaen, pr&amp;eacute;sidente du comit&amp;eacute; &amp;eacute;thique n&amp;deg;54), Laura Barrot (Ing&amp;eacute;nieure d&amp;rsquo;&amp;eacute;tudes Inserm, membre des comit&amp;eacute;s &amp;eacute;thiques n&amp;deg;10 et n&amp;deg;42) et Laurent Chazalviel (Ing&amp;eacute;nieur d&amp;rsquo;&amp;eacute;tudes CNRS, adjoint du comit&amp;eacute; &amp;eacute;thique n&amp;deg;54).&lt;/p&gt;

&lt;p&gt;Gr&amp;acirc;ce au financement de 45 576 &amp;euro; attribu&amp;eacute; par le FC3R en 2022, Ethi.3R a con&amp;ccedil;u &lt;strong&gt;un parcours de formation structur&amp;eacute; autour de quatre modules compl&amp;eacute;mentaires&amp;nbsp;&lt;/strong&gt;:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;
	&lt;p&gt;&lt;strong&gt;Les consid&amp;eacute;rations &amp;eacute;thiques&lt;/strong&gt;&amp;nbsp;(Module 1 obligatoire). Aborde notamment la relation chercheur-animal, l&amp;rsquo;historique de la protection animale, la mise en pratique des principes &amp;eacute;thiques, la communication sur la recherche animale et la notion de points limites.&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;&lt;strong&gt;Le cadre r&amp;eacute;glementaire &lt;/strong&gt;(Module 2 obligatoire). Consacr&amp;eacute; aux obligations l&amp;eacute;gales, aux proc&amp;eacute;dures exp&amp;eacute;rimentales, &amp;agrave; la gravit&amp;eacute; des proc&amp;eacute;dures et aux appr&amp;eacute;ciations r&amp;eacute;trospectives.&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;&lt;strong&gt;Comment &amp;eacute;valuer une demande d&amp;rsquo;autorisation de projet&amp;nbsp;&amp;nbsp;&lt;/strong&gt;(Module 3 facultatif). Etape cl&amp;eacute; du travail des comit&amp;eacute;s, avec un focus sur la pratique concr&amp;egrave;te de l&amp;rsquo;&amp;eacute;valuation &amp;eacute;thique.&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;&lt;strong&gt;Les statistiques &lt;/strong&gt;- (Module 4 non obligatoire). Vise&amp;nbsp;&amp;agrave; renforcer la compr&amp;eacute;hension des tests statistiques et du dimensionnement exp&amp;eacute;rimental.&lt;br /&gt;
	&amp;nbsp;&lt;/p&gt;
	&lt;/li&gt;
&lt;/ul&gt;

&lt;h2&gt;Un premier bilan positif&lt;/h2&gt;

&lt;p&gt;La premi&amp;egrave;re session de formation, organis&amp;eacute;e entre mai et ao&amp;ucirc;t 2025, a rassembl&amp;eacute; 587 participants. &amp;Agrave; l&amp;rsquo;issue de cette session, 409 attestations de r&amp;eacute;ussite ont &amp;eacute;t&amp;eacute; d&amp;eacute;livr&amp;eacute;es, repr&amp;eacute;sentant environ 18 % des membres de C2EA form&amp;eacute;s au niveau national. Les taux de participation et de r&amp;eacute;ussite aux quiz sont &amp;eacute;lev&amp;eacute;s, avec une grande satisfaction&amp;nbsp;des participants.&lt;/p&gt;

&lt;p&gt;Une deuxi&amp;egrave;me session, organis&amp;eacute;e d&amp;rsquo;octobre &amp;agrave; d&amp;eacute;cembre 2025, confirme cet engouement avec 606 participants inscrits et 348 attestations de r&amp;eacute;ussite d&amp;eacute;livr&amp;eacute;es. Cette nouvelle session a permis d&amp;rsquo;apporter plusieurs am&amp;eacute;liorations : la simplification des acc&amp;egrave;s &amp;agrave; la plateforme, l&amp;rsquo;am&amp;eacute;lioration des questions de quiz, la mise &amp;agrave; disposition de la majorit&amp;eacute; des documents en t&amp;eacute;l&amp;eacute;chargement et la clarification des informations figurant sur les attestations.&lt;/p&gt;

&lt;p&gt;Au total, pr&amp;egrave;s de 34 % des 2200 membres des comit&amp;eacute;s d&amp;#39;&amp;eacute;thique ont d&amp;eacute;sormais &amp;eacute;t&amp;eacute; form&amp;eacute;s form&amp;eacute;s gr&amp;acirc;ce &amp;agrave; Ethi.3R.&lt;/p&gt;

&lt;h2&gt;L&amp;rsquo;avenir d&amp;rsquo;Ethi.3R&lt;/h2&gt;

&lt;p&gt;Pour ses d&amp;eacute;veloppeurs, la plus belle r&amp;eacute;ussite d&amp;rsquo;Ethi.3R dans cinq ans serait que l&amp;rsquo;ensemble des membres des comit&amp;eacute;s d&amp;rsquo;&amp;eacute;thique fran&amp;ccedil;ais ait suivi cette formation et que tous les nouveaux membres se forment &amp;agrave; Ethi.3R en compl&amp;eacute;ment des &amp;nbsp;autres formations disponibles (Gircor, Charles River, e-thiX) d&amp;egrave;s leur entr&amp;eacute;e dans un comit&amp;eacute;. La cellule AfiS pourrait ainsi int&amp;eacute;grer ces chiffres dans les audits de comit&amp;eacute; et les valoriser aupr&amp;egrave;s de la Commission europ&amp;eacute;enne. Leur souhait est &amp;eacute;galement que la formation puisse prendre de l&amp;rsquo;ampleur, notamment dans les pays francophones europ&amp;eacute;ens qui pourraient en b&amp;eacute;n&amp;eacute;ficier.&lt;/p&gt;]]></content><enclosure url="https://www.fc3r.com/actualites/d/115-actuethi3r.jpg"  type="image/jpeg" lenght="960" /><image><title>Illustration</title><link>https://www.fc3r.com/actualites/d/115-actuethi3r.jpg</link><url>https://www.fc3r.com/actualites/d/115-actuethi3r.jpg</url><width>960</width></image></item><item><title>Louis Schweitzer: his work on behalf of laboratory animals and animal ethics</title><link>https://www.fc3r.com/actualites/louis-schweitzer-his-work-on-animal-ethics-113.html</link><pubDate>17 Nov 2025</pubDate><description><![CDATA[A humanist and unifier, Louis Schweitzer was renowned for his commitment to the animal cause and his involvement in the FC3R to promote the 3Rs.]]></description><content><![CDATA[&lt;p&gt;Present since the creation of the FC3R in 2021, Louis Schweitzer was appointed president of the COR ( or &lt;a href="https://www.fc3r.com/en/FC3R-structure-and-team.php" target="_blank"&gt;Advisory and Reflection Council&lt;/a&gt;) in 2022, a role he enthusiastically fulfilled until 2025, providing constant, benevolent and unifying support. His method consisted of consulting and analyzing different points of view in order to arrive at a synthesis or compromise. Defining himself as a reformer, he advocated sharing, dialogue and diplomacy to advance the cause of laboratory animals and the 3Rs.&lt;/p&gt;

&lt;p&gt;He constantly sought to gain a detailed understanding of the legal framework for animal experimentation and the application of the 3Rs, engaging in dialogue with the various stakeholders involved in animal experimentation in France: ministerial departments, ethical review bodies, animal experimentation ethics committees, and professional associations. Drawing on his leadership experience, he has brought a pragmatic vision, based on data analysis and comparison at the European level, in order to identify avenues for progress.&lt;/p&gt;

&lt;p&gt;He helped FC3R get established and set up, and played a part in defining its future direction. Convinced of the value of supporting FC3R in conducting high-quality research that is less dependent on animals and focused on progress, he tirelessly promoted FC3R and its work to various audiences, including the press, conferences attendees and government departments. He was a constant ambassador for our centre and its activities, as well as a staunch defender of the cause of laboratory animals. Concerned about the sustainability of the FC3R, he supported and advised it on its future developments, particularly with a view to expanding to encompass all sectors of public and private research.&lt;/p&gt;

&lt;p&gt;Under his chairmanship, the COR was structured into several thematic working groups dedicated in particular to the analysis of severe procedures in France, the identification of indicators for monitoring and evaluating the success of 3R policies, education and training programmes in animal ethics and alternative methods, and standards and guides for good practice in animal experimentation.&lt;/p&gt;

&lt;p&gt;At the inaugural AFSTAL conference on 12 June 2024, entitled &amp;quot;Science and society: the challenges&amp;quot;, Louis Schweitzer publicly presented his vision. Recognizing the acceleration of scientific knowledge , the growing acknowledgement of animal sensitivity and the slight reduction in the use of animals in France, as well as the high severity of procedures, he advocated for ethical and societal advancements in animal experimentation, which he believes are essential for medical progress. According to him: &amp;ldquo;the obstacle is not science, but habit and a failure to question practices&amp;rdquo;.&lt;/p&gt;

&lt;p&gt;To remedy this situation, he put forward several proposals that resulted in concrete actions by the COR working groups and the FC3R operational team.&lt;/p&gt;

&lt;p&gt;He promoted a comparative study of European practices in order to identify ways of improving animal experimentation, particularly with a view to better understanding the reasons for the high proportion of severe procedures reported in France.&lt;/p&gt;

&lt;p&gt;He emphasized the importance to improve the quality and reliability of annual statistics on the use of animals for scientific purposes, in order to enable the comparison with other countries and monitor progress. To harmonize the assessment of procedure severity and consolidate statistical data, the COR&amp;#39;s severity working group has drawn up a &amp;quot;&lt;a href="https://www.fc3r.com/bib/2025-06-30_1751282238-234cc7.pdf" target="_blank"&gt;Guide to assessing actual severity&lt;/a&gt;&amp;quot;, available to the scientific community.&lt;/p&gt;

&lt;p&gt;He reiterated that ethics committees overseeing animal experimentation play a crucial role, but that their effectiveness could be improved by reducing their number, standardizing their practices, and allocating them greater resources.&lt;/p&gt;

&lt;p&gt;He emphasized the importance of implementing the 3Rs principle, with a particular focus on replacement as a means of progress, and the need for substantial funding and a coordinating structure, such as the FC3R.&lt;/p&gt;

&lt;p&gt;He has often highlighted the importance of providing training and support for individuals involved in animal experimentation &amp;mdash; researchers, veterinarians, technicians and members of ethics committees &amp;mdash; in order to strengthen the ethical and scientific culture of the 3Rs within institutions. This involves setting up a directory of alternative methods (AREA) and a catalogue listing guides and benchmarks for good practice (BAFiS) to facilitate access to information.&lt;/p&gt;

&lt;p&gt;In conclusion, we endorse and perpetuate Louis Schweitzer&amp;#39;s observation that medical science and animal welfare initiatives converge in their efforts to alleviate suffering and enhance the quality of life of those affected. We must reduce the number of cases in which improving human welfare involves animal suffering:&amp;quot;One health frames science and ethics&amp;quot;.&lt;/p&gt;]]></content><enclosure url="https://www.fc3r.com/actualites/d/113-vignettels.png"  type="image/jpeg" lenght="960" /><image><title>Illustration</title><link>https://www.fc3r.com/actualites/d/113-vignettels.png</link><url>https://www.fc3r.com/actualites/d/113-vignettels.png</url><width>960</width></image></item><item><title>The "Replacement Checklist": a practical tool for research project designers and reviewers</title><link>https://www.fc3r.com/actualites/replacement-checklist-guiding-funders-and-reviewers-114.html</link><pubDate>17 Nov 2025</pubDate><description><![CDATA[The Replacement Checklist is a tool designed for researchers and reviewers to structure and assess the replacement process.]]></description><content><![CDATA[&lt;p&gt;In 2023, the &lt;a href="https://nc3rs.org.uk/role-review-and-regulatory-approvals-processes-animal-research-supporting-implementation-3rs-2023" target="_blank"&gt;NC3Rs published a report&lt;/a&gt; evaluating calls for projects involving animals in terms of their consideration of the 3Rs principle (Replace, Reduce, Refine). The report made several recommendations to funders, evaluators, and ethics committee members. The main finding was that the &amp;quot;Replacement&amp;quot; principle was the most difficult to apply and did not appear to be taken into account in project review processes. In fact, members of animal welfare and ethical review bodies (AWERB) and members of animal science regulatory unit&amp;nbsp;(&lt;a href="https://www.gov.uk/government/collections/animals-in-science-regulation-unit#about-asru" target="_blank"&gt;ASRU)&lt;/a&gt; rarely recommend replacements.&lt;/p&gt;

&lt;p&gt;To strengthen consideration of the &amp;quot;Replacement&amp;quot; principle, the British NGO &amp;quot;&lt;a href="https://replacinganimalresearch.org.uk/" target="_blank"&gt;Replacing Animal Research&lt;/a&gt; &amp;quot; developed the &amp;quot;&lt;a href="https://replacinganimalresearch.org.uk/resources/replacement-checklist/" target="_blank"&gt;Replacement Checklist&lt;/a&gt;&amp;quot; in 2025. The checklist is intended for those who evaluate funding applications or project authorization requests (PARs) involving the use of animals for scientific purposes. Although the checklist is intended for the British public, its principles apply to all European Union countries.&lt;/p&gt;

&lt;p&gt;This tool addresses the challenge evaluators and researchers face in identifying alternatives to animal models due to a lack of labeling systems, interdisciplinary collaboration, and clear methodological guidelines. Furthermore, many of the existing guidelines, including &lt;a href="https://norecopa.no/PREPARE" target="_blank"&gt;PREPARE&lt;/a&gt; and &lt;a href="https://arriveguidelines.org/" target="_blank"&gt;ARRIVE&lt;/a&gt;, concentrate on reduction and refinement.&lt;/p&gt;

&lt;h2&gt;Six key questions to guide project design and presentation&lt;/h2&gt;

&lt;p&gt;The checklist is divided into six themes&amp;mdash;What, Where, How, When, Who, and Why&amp;mdash; and proposes a series of questions to promote a structured approach shared by all stakeholders, including non-specialists. Project leaders should ask themselves these questions during their bibliographic research, and include answers when completing funding applications, project authorization and transparency documents.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Which areas were covered by the literature review(s)?&lt;/strong&gt;&lt;br /&gt;
Non-animal technologies are often poorly referenced because publications on them do not use standard terms such as: 3Rs (replace, reduce and refine), non-animal methods, NAMs, among others. This underscores the importance of broadening and diversifying the keywords used and adapting them to the relevant discipline. If the results are unsatisfactory, the relevance of the research methodology used should be questioned.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Where was the information obtained?&lt;/strong&gt;&lt;br /&gt;
It is essential to use specialized databases, some of which are unknown to the scientific community, as well as gray literature, such as preprints, reports and &lt;a href="https://www.fc3r.com/short-notes-library-FC3R.php" target="_blank"&gt;ShortNotes&lt;/a&gt;. The FC3R via &lt;a href="https://www.fc3r.com/fria/autres-ressources.php" target="_blank"&gt;FRIA&lt;/a&gt; provides access to the primary English-language databases (see Table 1), and &lt;a href="https://norecopa.no/search?fq=type:%22Databases%22&amp;amp;sort=name_s%20asc&amp;amp;q=*&amp;amp;facet.limit=125" target="_blank"&gt;Norecopa&lt;/a&gt; offers an extensive directory.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;How was the information search conducted?&lt;/strong&gt;&lt;br /&gt;
Specific keywords adapted to each database must be used.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;When was the information published and when was the research conducted?&lt;/strong&gt;&lt;br /&gt;
The cited publications should reflect the latest scientific advances.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Who was consulted for advice?&lt;/strong&gt;&lt;br /&gt;
Sources of information can include individuals, networks, or communities of experts, such as the &lt;a href="https://www.fc3r.com/area/"&gt;AREA&lt;/a&gt; directory, &lt;a href="https://gdr-organoides.cnrs.fr/"&gt;GDR Organoids&lt;/a&gt;, &lt;a href="https://www.gdrmicrofluidique.com/"&gt;GDR Nano, and Microfluidics&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Why were the alternative methods identified not selected or deemed insufficient to replace animal testing?&lt;/strong&gt;&lt;br /&gt;
Results from bibliographic and other research may be rejected if they do not meet the project&amp;rsquo;s scientific requirements, lack validated data, or have technical limitations that prevent their direct application to the intended research context.&lt;/p&gt;

&lt;h2&gt;A simple, integrated tool to improve evaluation and scientific quality&lt;/h2&gt;

&lt;p&gt;The checklist can be integrated directly into funding application forms or used by researchers as a self-assessment tool. No long or complex report is required&amp;nbsp;; simply indicate the databases consulted, the date of the research, the models explored, and the contacts made with specialized organizations.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;The benefits are numerous:&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;
	&lt;p&gt;For funders, it standardizes evaluations, improves scientific quality, and optimizes the allocation of funds.&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;For research organizations and the private sector, it reinforces ethics, social responsibility, and brand image while stimulating innovation (NAMs).&lt;/p&gt;
	&lt;/li&gt;
	&lt;li&gt;
	&lt;p&gt;For charitable organizations, it reinforces ethical considerations and transparency, thereby reassuring the public and donors that resources are being used responsibly.&lt;/p&gt;
	&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Additionally, it is crucial to encourage researchers and evaluators to take advantage of the free training courses offered to support the implementation of alternative methods. In particular, they should take the EU-52 ETPLAS (Education &amp;amp; Training Platform for Laboratory Animal Science) module &amp;quot;&lt;a href="https://learn.etplas.eu/courses/eu-52/" target="_blank"&gt;Searching for (existing) alternatives without the use of animal experimentation&lt;/a&gt;&amp;quot; (takes a minimum of one hour to complete).&lt;/p&gt;

&lt;p&gt;In conclusion, the &amp;quot;Replacement Checklist&amp;quot; is a tool that organizes the search for alternatives to animal testing to harmonize and improve the design and evaluation of research projects.&lt;span style="font-size:12pt"&gt; &lt;/span&gt;&lt;/p&gt;]]></content><enclosure url="https://www.fc3r.com/actualites/d/114-actucheck-list-en.png"  type="image/jpeg" lenght="960" /><image><title>Illustration</title><link>https://www.fc3r.com/actualites/d/114-actucheck-list-en.png</link><url>https://www.fc3r.com/actualites/d/114-actucheck-list-en.png</url><width>960</width></image></item></channel></rss>
