With @nicolettapetridou.bsky.social we wrote a research briefing on our recent publication!
Nice thread! @laura-rustarazo.bsky.social and @epimechfc.bsky.social
EMBL graduated its biggest class ever at the end of April, celebrating with 60 fellows who submitted or defended their theses over the past 12 months.
Representing 22 different countries, EMBL graduates continued to show a diversity in science as well as background. Congratulations graduates!
Work from our lab to read! Adhesion rules!
💫 Our paper is now published at @natcellbio.nature.com! So excited about this work done during my PhD at @embl.org in the group of @nicolettapetridou.bsky.social along with our great collaborators! 🐟🎉
See you on Thursday! 🐟🔬🖥️
In a collaboration between the Crick and @embl.org, researchers used a mix of experimental work in zebrafish and theoretical modelling to discover a feedback loop between an embryo’s changing material properties, such as its rigidity, and the signalling molecules that guide patterning.
Very happy to announce that I will be joining the Faculty of Biology & @cibss.bsky.social at @uni-freiburg.de as an Emmy-Noether funded group leader.
We will tackle the molecular and genetic basis of developmental timing and size control using diverse Oryzias species. We are hiring at all levels !
Our latest work on shape-programmable tissues is out in @science.org. By positioning topological defects in cellular nematics, we encode frustrated 2D force fields that relax into predictable 3D shapes. Collaboration with Marino Arroyo’s lab, led by @pauguillamat.bsky.social at @ibecbarcelona.eu.
☕ @nicolettapetridou.bsky.social & co report a feedback loop between Nodal signaling and tissue phase transitions in zebrafish #embryos. Nodal alters adhesion, triggering tissue rigidification and reduced porosity, which limits its diffusion and speeds up Lefty expression.

How rigid a tissue is coordinates a crucial period of cell patterning, ensuring that embryos develop the right shape and organise their cell layers correctly at the same time.
How can structures at the vertex of 3 cells have effects at the tissue level?
Join me, @laura-rustarazo.bsky.social, to explore how tricellular junctions (TCJs) act as local tension sensors and regulators of global tissue organization. 🧵⤵️ doi.org/10.1126/scie...
Glad to see this out in its final form!

What changed since the preprint? Wonderful experiments disentangling the effect of receptor binding vs tissue porosity on Nodal diffusion, plus one of the smoothest review experiences! Thanks @natcellbio.nature.com & reviewers 🙏
Join us for the next VGZT, featuring complementary approaches to understanding dynamic tissue organization!

During embryogenesis, morphogen signalling is known to pattern tissues as they remodel. Using genetic and optogenetic perturbations, together with theoretical frameworks of phase transitions and bioch...
⚡ Our paper is now out in @natphys.nature.com !
This version now includes a detailed molecular characterisation of the optogenetic perturbations, new insights on the relevance of tricellular junctions for tissue morphology, and beautiful light-sheet timelapses. 🔬

Tissue phase transitions are key to morphogenesis. Now adhesion-driven rigidification is identified as key to epithelial organization but only if uncoupled from density-driven jamming.
🎉 Excited to share our new work: “Adhesion-driven tissue rigidification triggers epithelial cell polarity”, now on @biorxivpreprint.bsky.social !
A huge thank you to @nicolettapetridou.bsky.social, Bernat, @crisp-c.bsky.social, Adrián, and everyone involved! 🙌
