What determines how epithelial cells divide when shape cues disappear? Our new work in @natcomms.nature.com shows that divisions follow maximal stress anisotropy — a “principal-stress rule” beyond Hertwig’s long-axis rule. Fantastic work led by @luanger.bsky.social www.nature.com/articles/s41...

First preprint from the lab, led by @gabbov.bsky.social! We identify a metabolic bottleneck that helps set the pace of human development: low levels of the redox enzyme GPD1L limit NADH recycling. Boosting GPD1L mimics mouse cells and accelerates development! www.biorxiv.org/content/10.6...

Happy to share our new preprint! We uncover how local force imbalances drive keratinocyte delamination and upward motion, while neighboring cells close the basal layer below. Amazing work from @andreasschoenit.bsky.social! www.biorxiv.org/content/10.6...

🚨 New preprint alert! 🚨 Choanoflagellates reorganize their global cytoskeletal architecture within seconds to explore confined microspaces. This is the main PhD work of the amazing @maitefreired.bsky.social www.biorxiv.org/content/10.6... A tread 🧵⬇️

Excited to share a new preprint! We address a longstanding question related to stratifying tissues: What are the physical mechanisms that drive epidermal cell delamination? Find out why this👇 traction force pattern emerges and how it is linked to upward cell motion: www.biorxiv.org/content/10.6...

New publication, new insights into left-right patterning in mice. We revisit the role of the node, from a left-right organiser to one biasing factor among others. www.science.org/doi/10.1126/...

Wnt and Nodal asymmetries stratify mouse laterality phenotypes in the absence of node flow
Asymmetry establishment without node flow reveals an alternative symmetry-breaking event in the mesoderm involving WNT signaling.

Really excited to finally show off our work on the specification of neuroblasts. While it has been a long-standing model for lateral inhibition, we show that Notch does not select the NB, but instead reinforces fate decisions. www.cell.com/current-biol... @currentbiology.bsky.social

Positional cues, not Notch, direct neuroblast selection during early neurogenesis in the Drosophila embryo
Using quantitative live imaging, Green et al. show that proneural gene expression is biased by positional cues and that Notch is activated only after neuroblast selection in the Drosophila embryo. Thi...

Happy to share our new review on biophysical principles of cell competition and elimination: www.cell.com/trends/cell-... With @bladoux.bsky.social and @rmmege.bsky.social, we discuss mechanical fitness, how loser cells are removed through various strategies and how forces can effect their fate

I’m pleased to share our latest preprint (my first as 1st-author) from Jérôme Gros’ group (@jeromegros.bsky.social), now on bioRxiv. It reports actin and myosin dynamics during epithelial remodeling in avian gastrulation. (doi: doi.org/10.64898/202...)

How is developmental speed regulated ? 🪰 Happy to share my PhD story from Schweisguth Lab @devstempasteur.bsky.social. Here we show that cellular NAD+ availability and redox constrain developmental speed in the fly eye. www.biorxiv.org/content/10.1... A big thanks to everyone involved!

How can we investigate the mechanical state of cells within a tissue, assessing if they are under compression or tension? @luanger.bsky.social and I highlight methods in a short 🧵 with @epimechfc.bsky.social
