WebJul 13, 2024 · Actomyosin cortical contractility drives many cell shape changes including cytokinetic furrowing. While positive regulation of contractility is well characterized, counterbalancing negative regulation … 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. WebThe intercellular canal containing the midbody is one of the most prominent structures in dividing animal cells, yet its function in the completion of cytokinesis by abscission remains largely unknown. This is because of its small size, which makes it difficult to investigate the cytoskeletal and membrane dynamics underlying abscission by standard light microscopy. photo of 3 in one toddler bed
