1/ 🎉Excited to share our new preprint @vignjeviclab.bsky.social @davidbrueckner.bsky.social :

"Self-organization of tumor heterogeneity and plasticity"
biorxiv.org/content/10.1...

Tumor heterogeneity and plasticity drive metastasis and relapse. How is tumor patterning coordinated?

Epithelial crowding drives membrane depolarisation by ENaC/Na+ entry which triggers rapid volume loss, piezo activation and live cell extrusion. Importantly, low intracellular ATP primes cells for live extrusion by preventing the restoring of mb polarisation.

We are all super happy and proud to see our work on the function and evolution of the #cephalic #furrow published in @nature.com. Let me say a few things about the background and history of this work on the #Evolution_of_Morphogenesis (1/12)

New preprint out! We show how cellular nematic order can be harnessed to program tissue-wide force fields and guide 3D shape transformations.

The tissue morphogenesis logic, now engineered into living, programmable materials.

Many cells during development are exposed to caspase activation and yet survive. Why some die and not others ? We found out that the memory of previous caspase activation bias significantly later death comitment and bias death distribution and single cell decision

🥳 Thrilled to share our lab's first preprint, led by our talented postdoc Justine Creff! 👩🏻‍🔬 We tackled a fundamental question: how the epithelium withstands mechanical stress at the interface of cells with distinct geometries and mechanics, such as enterocytes (E) and goblet cells (G) (1/9)

How oncogenic clones can eliminate their neighbours to take over space ? There are different ways combining growth and interfacial tension induced compaction. Check out our latest preprint led by Léo Valon and Alexis Matamoro-Vidal to learn more about this 👇
