In all eukaryotes, cytokinesis is a big deformation process that a mother cell is divided into two daughter cells. It is involved in many mechanical actions, such as active contraction of microfilament, viscous flow of cytoplasm and big deformation of cortical membrane. In order to attain a better understanding of the cytokinesis process and corroborate a mechanical mechanism, various theoretical models were proposed. Recent works of cell mitosis experiments have approved that the site of contractile ring is determined by the biochemical stimulus from asters of the mitotic apparatus, actin and myosin assembly related to the motion of membrane phospholipid, local distribution and arrangement of microfilament cytoskeleton is different with cytokinesis phases.
