Mitotic cell rounding : ウィキペディア英語版 | Mitotic cell rounding
Mitotic cell rounding is a shape change that occurs in most animal cells that undergo mitosis. Cells abandon the spread or elongated shape characteristic of interphase and contract into a spherical morphology during mitosis. The phenomena is seen both in artificial cultures ''in vitro'' and naturally forming tissue ''in vivo''. ==Early observations== In 1935, one of the first published accounts of mitotic rounding in live tissue described cell rounding in the pseudostratified epithelium of the mammalian neural tube. Sauer noticed that cells in mitosis rounded up to the apical, or luminal, surface of the columnar epithelium before dividing and returning to their elongated morphology.
