Nice to have you here, and happy to participate to this Inserm Workshop on Organs-on-Chip. Do you think we can perfuse tear gas in a chip? On a minor model of retina, and then, compressing the chip to mimic tonfa hit?

A developmental biologist's guide to mechanics Read this Primer from our special issue #DevSIextracellular by Jialing Cao, @raphclement.bsky.social, @pflenne.bsky.social and colleagues. journals.biologists.com/dev/article/...
Intracellular force-generating mechanisms drive tissue-scale mechanical behaviors. The central schematic provides an overview of the major cellular force-generating mechanisms in developing tissues and serves as the basis for the four surrounding panels, which illustrate how these mechanisms generate distinct tissue-scale mechanical behaviors. It includes actomyosin contractility, actin polymerization, cell–cell adhesion and ion transport through membrane channels. These processes generate and transmit forces within and between cells. (A) ATP-dependent ion transport establishes an osmotic pressure difference (ΔP), driving water influx into the lumen. Black radial arrows indicate the outward mechanical effect of the luminal pressure during lumen expansion. (B) Actin polymerization at the tissue edge generates protrusive forces that drive coordinated, directional collective cell migration. Here, leading edge refers to the advancing front of a moving cell group, featuring specialized lead

The role of geometry in morphogenesis Read this Review from our special issue #DevSIextracellular by Ryan Harrison, Olivier Hamant and @timesaunders.bsky.social. journals.biologists.com/dev/article/...
Role of geometry in shaping tissues. Multiple factors, including cell shape (top left), boundary constraints (top right), topological inputs (bottom left) including from different cell alignment defects (±1/2) and biophysical factors (bottom right) impact how the final tissue form emerges (centre). Centre shows images of a 48 h neuruloid (left; magenta, DAPI; green, actin) and a young Arabidopsis flower (right) treated with oryzalin (depolymerised microtubules) thus showing isotropic growth, but no defect in patterning (organs are still initiated in the right position).
