1/4 New in Science: Gut renewal is not passive “crowd control.” Instead of being pushed out by crowding or dying from apoptosis, cells compete in a mechanical tug-of-war. Weaker cells are eliminated—reframing intestinal homeostasis as a force-regulated process. 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...
