A principal-stress rule for cell division in epithelia

Lucas Anger, Tianxiang Ma, Fanny Wodrascka, Andreas Schoenit, Kristian Thijssen, Satish Kailasam Mani, Marc-Antoine Fardin, Carine Rossé, René‐Marc Mège, Amin Doostmohammadi, Benoît Ladoux

The paper shows that cell division in epithelia follows a mechanical principal-stress rule rather than a geometric rule, as cells divide along their principal stress axis to relieve anisotropic stress.

Higher-Order Mechanical Neighbourhood Sensing Governs Cell Fate in Complex Tissues

Alphy John, Tianxiang Ma, Duncan J. D. Mackay, Elizabeth C Connolly, Julien Colombani, Amin Doostmohammadi, Ditte S. Andersen

The paper identifies a higher-order mechanical neighbourhood-sensing mechanism in Drosophila midgut that integrates cell identity and mechanics to regulate stem cell fate.

Mechanical Tension Actively Triggers RhoA-Mediated Cell Extrusion

Fanny Wodrascka, Tianxiang Ma, Pablo Gottheil, Robin Durand, Lucas Anger, Andreas Schoenit, Mallica Pandya, M Arnaud, Tien Dang, Siavash Monfared, Guillaume Charras, René‐Marc Mège, Amin Doostmohammadi, Benoît Ladoux, Simon de Beco

This study shows mechanical tension, not just biochemical signals, actively drives cell extrusion via RhoA-mediated contractility in epithelial monolayers.
