Frenster et al. utilize mosaic mouse gastruloids as a model of cell fitness and competition, identifying a temporal window between primed pluripotency and early gastrulation during which cell competit...

Spina bifida and anencephaly are neural tube defects caused by failure of embryonic neural tube closure. Successful closure requires elongation and apical constriction of neuroepithelial cells. These ...

Despite progress in probing tissue mechanics, direct long-term measurements in live embryonic epithelia are lacking. This limits our understanding of amniote embryonic morphogenesis, which takes place...
