WebMay 2, 2012 · Animal cell cytokinesis is initiated during anaphase, when the decline of CDK1 activity leads to a stabilization of microtubules and reorganization of the mitotic spindle. WebIn animal cells, cytokinesis involves the formation of a contractile actomyosin ring (CR) that sits at the base of the ingressing equatorial furrow. Constriction of the CR drives continuous membrane furrowing until only a narrow cytoplasmic bridge separates the two cells.
