WebCytokinesis in animal embryos requires the formation of the contractile ring, an actomyosin network that mediates pinching off of daughter cells after mitosis. One major unsolved problem in embryonic cleavage is why the cytokinetic furrow forms at a particular location, and why the spindles are oriented along particular planes of cleavage. WebSep 28, 2024 · Cytokinesis, the final step in cell division, begins with the formation of an actomyosin contractile ring, positioned midway between the segregated chromosomes. Constriction of the ring with concomitant membrane deposition in a specified spatiotemporal manner generates a cleavage furrow that physically separates the cytoplasm.
