Dear colleagues, positions at CNRS (and INRIA) will (in all probability) be announced this winter. By then it will however be too late to properly prepare an application. Recent PhDs, postdocs etc interested in such positions should get right now in contact with teams who would like to recruit them.

Preprint alert! We combined microfluidics, proteomics, and RNA-seq to map spatiotemporal protein expression during mouse somitogenesis and found a novel regulatory strategy: dynamic antagonistic gradients fine-tune signalling strength. doi.org/10.1101/2025...

Bird’s eye view, literally. 🐦👁️ Glowing quail embryo eye for #FluorescenceFriday, #DevBio 🧪🔬

Hi bsky! Do embryonic tissues have backup plans🔀? Gastruloids (model of body elongation) can build an axis through different cellular mechanisms when on adherent substrates instead of free floating. A case of developmental plasticity! w/ A. Delahaye & ‪@bensteventon.bsky.social‬ shorturl.at/v01DO

(1/10) I am excited to finally share our work on avian left/right symmetry breaking with you. We reveal a tissue-scale active torque dipole generated at the Hensen’s node, thanks to crazy experiments by Julia @juliapfanzelter.bsky.social and some analysis by me. doi.org/10.1101/2025...

What started with many quail eggs and put me on stage in a chicken suit has now resulted in a preprint www.biorxiv.org/content/10.1... Microsurgery with human eye-lashes, laser ablations, great analysis and insightful theory from @neipel.bsky.social told us more about avian L/R symmetry breaking.

Two new preprints from the @arjunraj.bsky.social‬ on #gastruloids. Both excellent. Exploring the relationship between macroscopic reproducibility v microscopic heterogeneity. Stunning experiments and much to think about biorxiv.org/content/earl... biorxiv.org/content/earl...

Birth defects kill twice as many children as cancer. Animal model are crucial; no stem-cell or computer models can yet recapitulate the embryo's complexity. If you support birth defects research tell NIH that animal models are important! Click & scroll below to comment. tinyurl.com/mr3he6bx

Great use of the transgenic quail model to answer very basic and important question in developmental biology !

🚨New preprint Glad to share my postdoc work on the role of the hypoblast in primitive streak induction! Discover how live imaging observations led us to revisit the molecular mechanisms governing embryonic axis induction Thanks to @jeromegros.bsky.social and all co-authors! doi.org/10.1101/2025...

Great work from Arthur Michaut again ! Very cool study on biophysical properties of the very young avian embryo. Congrats to Arthur, and to the teams of Francis and Jérôme !

This time-lapse captures 17 hours of axonal growth from a chicken dorsal root ganglion explant, visualized through the actin cytoskeleton using live confocal imaging. I just submitted this video to the Nikon Small World in Motion competition. Today is the last day to upload yours! 😉 🧪

Birth defects are the #1 cause of death in the first year of life (🧵). Birth defects kill more than twice as many children as cancer. Birth defects are diseases of developmental biology. Here are CDC statistics for 2021. 1/5 wisqars.cdc.gov/pdfs/leading...

This is an experimental project & will be looking for candidates with experience generating reporter lines, live-imaging and experimental embryology. Application deadline: 25th Feb. tinyurl.com/33jbu8fa

Birth defects are diseases of development and are the #1 cause of death in the first year of life. And birth defects kill more than twice as many children as cancer. 4% of ALL hospitalizations (for all ages) are due to birth defects. Economic impact of birth defects is > 22 billion dollars per year.
