Mitotic cell rounding
WebActomyosin-dependent mitotic rounding occurs in both cell culture and tissue, where it is involved in cell positioning and epithelial organization. How actomyosin is regulated to mediate mitotic rounding is not well understood. Here we characterize the mechanics of single mitotic cells while imaging actomyosin recruitment to the cell cortex.
