Not every cell react the same way to caspase activation. In our recent study (led by @tomcumming.bsky.social and initiated by @avillars.bsky.social ), we tried to better understand what explains this difference and outlined a role of past caspase exposure 👇 www.nature.com/articles/s41...

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...

Biophysics of lumen morphogenesis Read this Review from our special issue #DevSIextracellular by Byung Ho Lee, @hiraiwatetsuya.bsky.social, Masaki Sano, Alf Honigmann, Daniel Riveline, @anne-grapin.bsky.social and colleagues. doi.org/10.1242/dev....
Physical principles governing lumen formation and tissue morphology. (A) A lumen surrounded by an epithelial cell layer is shaped by the balance between luminal pressure and mechanical resistance from the tissue and the ECM layers. Ion pumping (Jion) generates a gradient of ions across the monolayer and an osmotic pressure difference (ΔΠ). Water can enter through a flux (Jwater), which generates a hydrostatic pressure difference, ΔP, that can expand the lumen. This hydrostatic pressure is opposed by cortical tensions at the apical, basal and lateral cell surfaces, respectively (γapical, γbasal and γlateral), by cell–cell adhesion, nadh, and by the elastic and viscous properties of both the tissue and the ECM. The detailed inset illustrates how cell division time and tissue osmolarity contribute to the evolving mechanical state of the organoid. Osmotic pressure triggers the generation of hydrostatic pressure, which is faced by the cell monolayer and might, in turn, increase its mass by proliferating. Timescales of increase in luminal volume, cell proliferation, tissue and ECM viscosities contribute to determining the lumen shape. (B) Young–Laplace law applied to the curved epithelial/luminal interface. The pressure difference across the tissue layer depends on cortical tension and curvature according to the Young–Laplace equation (Box 1). Here, R1 and R2 are the two principal radii of curvature of the curved interface. They originate from the fact that a three-dimensional surface can bend along two independent directions. For a spherical lumen, the two radii are equal, whereas for an irregular or elongated lumen, they may differ locally.
