Abstract
Nuclear envelope breakdown in metazoan cells is thought to be facilitated by microtubules, which pull on the nuclear membranes. Unexpectedly, an F-actin meshwork helps to tear down the large nucleus of starfish oocytes and to prevent chromosome loss in meiosis.
摘要
真核细胞的核膜崩解被认为是由微管介导的，微管拉动核膜。出乎意料的是，一个 F-actin 网格结构有助于撕裂海星卵母细胞的大细胞核，并防止减数分裂过程中的染色体丢失。
