Cytokinetic furrow
WebMay 2, 2012 · Nature Cell Biology - Cytokinesis is the process by which mitotic cells physically split in two following chromosome segregation. Dividing animal cells first … 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.
