⚡ 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.
Multinucleate cells challenge deeply-held assumptions about complexity, ecological success and evolution. Postdoc extraordinaire and gifted writer @mrosjac.bsky.social tackles this subject with aplomb - tell us what you think!

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 🙏
Autorino et al. report a feedback loop between Nodal signalling and tissue phase transitions in zebrafish embryos. Nodal alters adhesion, triggering tissue rigidification and reduced porosity, which l...
