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. WebApr 23, 2024 · Like during cytokinetic abscission, these two pathways act at different steps and both promote de novo lumen formation at the center of the cyst, around the first cytokinetic bridge. In vivo, a recent study also revealed that CCM-3 plays a role both in promoting furrow contraction to completion and in cell polarity 129, 130. Mutations in …
Abscission proceeds by removal of cytoskeletal structures from the cytokinetic bridge, constriction of the cell cortex, and plasma membrane fission. The intercellular bridge is filled with dense bundles of antiparallel microtubules that derive from the central spindle.
