New paper from our lab and @friedrich-group.bsky.social !! Insights into morphogen gradient scaling to regenerate a limb at the appropriate size. #axolotl, #limbregeneration

Specialized signaling centers direct cell fate and spatial organization in a mesodermal organoid model Stem cell–derived mesodermal organoids reveal how signaling centers guide cell fate and tissue organization.

🎉 Our deconstructed, stem-cell–based approach to studying signaling centers and limb-development cell types is out! 🥳 So nice to see it in its final form after the preprint— and huge thanks to the community for all the enthusiasm and interest since then!

Big congratulations to all authors, and heartfelt thanks to our collaborators, and colleagues at @EPFL and at our new home @mpi-bio-fml.bsky.social, and to @snsf.ch NRP79 for generous support!

Cadherins modulate the self-organizing potential of pseudo-embryos Gastruloids derived from ES cells mimic embryonic patterning through robust self-organization. Mayran et al. uncover that this competence depends on a cadherin switch regulated by Snai1-driven E-cadhe...

Happy to present the final version of our Cadherin and gastruloid manuscript, online at @cp-cellreports.bsky.social.

IT'S HAPPENING! 💥 I'm psyched to launch the collaboration between @qedscience.bsky.social & @openrxiv.bsky.social @biorxivpreprint.bsky.social! Preprint + q.e.d = your science is out there, and anyone can appreciate it. Let's care about making discoveries, and not on “getting published” (1/3) 👇

🧪 Looking for candidates with experience in stem cell culture, quantitative image analysis, or modeling — and eager to learn!

🔬 Limb regeneration depends on regenerative signaling center cells — but how do these cells influence others to proliferate, migrate, or differentiate?
We’re recruiting PhD or Postdoc candidates to explore this with our collaborator @osvaldo-chara.bsky.social !

Delighted that Ziqi Dong's PhD paper is out for all to read! Hypoxia is fundamental to normal development, and fascinating! Thanks to all of our co-authors including @jamesnathanlab.bsky.social @jellevda.bsky.social authors.elsevier.com/sd/article/S...

🧠 The Lipid #Brain Atlas is out now! If you think #lipids are boring and membranes are all the same, prepare to be surprised. Led by @lucafusarbassini.bsky.social with Giovanni D'Angelo's lab, we mapped membrane lipids in the mouse brain at high resolution.

Huge congratulations to Cagri and the team! This looks truly revolutionary!

Induction of menstruation in mice reveals the regulation of menstrual shedding During menstruation, an inner layer of the endometrium is selectively shed, while an outer, progenitor-containing layer is preserved to support repeated regeneration. Progress in understanding this co...

I’m thrilled to share my postdoc work and the first paper from the McKinley Lab! 🎉

We built the first transgenic model of menstruation in mice.
We used it to uncover how the endometrium organizes and sheds during menstruation. 🧪

We are building a small expert team within the @bokelab.bsky.social at @crg.eu @prbb.org to investigate fundamental questions in oocyte cell biology, focusing on how proteostasis regulation influences dormancy and fertility.

Mechano-osmotic signals control chromatin state and fate transitions in pluripotent stem cells - Nature Cell Biology McCreery, Stubb et al. show that mechano-osmotic changes in the nucleus induce general transcriptional repression and prime chromatin for cell fate transitions by relieving repression of specific differentiation genes.

How do #stemcells integrate information to coordinate fate decisions? Delighted to finally see our work showing how growth factors regulate the mechano-osmotic state of the #nucleus and #chromatin to control #pluripotency exit out! www.nature.com/articles/s41... see 🧵 👇

Are you interested on how regenerating tissues transit between stages? Am sharing here our work showing that during #Xenopus tail regeneration, tissue stiffening activates a Piezo1-Yap1 mechanosensitive cascade to allow wounded epithelia to transit into regenerative states!
