Why this matters ⬇️
A platform of robust patient-derived leukemia models covering subgroups for which no cell lines exist
Preclinical cancer research requires robust model systems, especially for poor prognosis entities like acute myeloid leukemia (AML), a highly aggressive blood cancer. Here, primary tumor cells from 13...

Happy to share that my PhD has finally taken the shape of a paper! ✨

Huge thanks to all authors, especially @davidbrueckner.bsky.social & @ehannezo.bsky.social for leading the modeling and @raimonsunyer.bsky.social & @xaviertrepat.bsky.social for their invaluable supervision.

How do cells navigate up gradients of adhesive proteins?
🤔

Termed "Haptotaxis", this effect is ubiquitous in cell migration, but it's mechanism was poorly understood

We show that passive friction directs cells & explains complex trajectories on gradients

1/11 In @science.org: A new perspective on how our intestines renew. Cells are not “pushed out” by crowding or die from apoptosis. Instead, cells play a mechanical tug-of-war, where weaker cells extrude, reframing gut renewal as force-regulated. www.science.org/doi/10.1126/...
Epithelial tension controls intestinal cell extrusion
Cell extrusion is essential for homeostatic self-renewal of the intestinal epithelium. Extrusion is thought to be triggered by crowding-induced compression of cells at the intestinal villus tip. In th...
