Mechanosensitive feedback organizes cell shape and motion during hindbrain neuropore morphogenesis Pérez-Verdugo et al. show that hindbrain neuropore closure is driven by surface ectoderm actomyosin purse-string tension and active migration. These forces create reproducible patterns of cell elongat...

Excited to share our new publication on the mechanics of cranial neural tube closure. A really enjoyable and fruitful collaboration bridging Developmental Biology and biophysical modelling. Take a look here!

Excited to start a new chapter with my team’s relocation to the Pink City, at @cbitoulouse.bsky.social!

Looking forward to new scientific interactions on campus (@laas, LPT, IRIT, ANITI…) at the interface of biology, physics & computational science.

Please check out our new preprint! Using single cell analysis paired with HCR to visualize transcript localization we have identified cell and tissue-specific expression of various genes encoding tubulins, kifs, and dyneins during neural crest development!

Happy to share this work from Carlos Camacho de la Maccora that reveals how rates of posterior progenitor addition and anterior vacuolation are balanced across the notochord. With Alberto Ceccarelli and @osvaldo-chara.bsky.social we present a model of long-range communication to provide robustness.

We‘re looking for a motivated Master student to join our team!

Congratulations Ina !

Excited to share a fantastic PhD opportunity combining interdisciplinary approaches with me, @alexgfletcher.bsky.social and @rorylcooper.bsky.social sky.social! Please share!

📣Our project, “Mechanometabolic Control of Vertebrate Limb Elongation,” has been funded by Wellcome!
Over the next 8 years, we’ll collaborate with @manningresearch.bsky.social and Nathalie Agar’s group to understand the mechanics of ECM-rich mesenchymal tissues! Funded positions available!🎉

Congratulations Ale :) I am glad to read that!

Show time for paper #2 !!!

And another great gut epithelium story from our cool neighbors !!!😎 @cbitoulouse.bsky.social

Robust pan-junctional reinforcement preserves the gut epithelial barrier under mechanical stress Epithelia are specialized tissue barriers that safeguard the organism's internal milieu from the hostile external environment, a function critically dependent on intercellular junctions. In the colon,...

Ever wondered how adult organs preserve epithelial barrier integrity while continuously exposed to mechanical stress? We tackled this question in our new preprint – led by our brilliant PhD student Vishnu Krishnakumar! (1/11)

Congratulations @mtrani.bsky.social and @campaslab.bsky.social @jesseveenvliet.bsky.social labs !!! Looks great 🤩, impressive measurements !!! Looking forward to digging into it! I am curious: Where is the actin cap located in the mouse embryo, surrounding the whole PSM?

Great news! Congratulations !!!

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.

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!

An active torque dipole across tissue layers drives avian left-right symmetry breaking Unlike in mice, frogs, and fish, left-right (L/R) body axis formation in avian embryos does not arise from the chiral beat of cilia. Instead, a counter-clockwise tissue rotation around Hensen′ node, t...

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.

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
