In animal cells, cytokinesis is mediated by the constriction of a cortical ring. In this issue, Carvalho et al. (2009) show in embryos of the worm Caenorhabditis elegans that the rate of ring constriction during cytokinesis is proportional to the initial cell perimeter, ensuring that the duration of cytokinesis is cell-size independent.
在动物细胞中，胞质分裂由皮质环的收缩介导。在本期中，卡瓦略等人（2009年）在秀丽隐杆线虫的胚胎中表明，胞质分裂期间环收缩的速率与初始细胞周长成正比，确保胞质分裂的持续时间与细胞大小无关。
