Midbody abscission
Web5 jul. 2024 · Abscission is the final step of cell division, mediating the physical separation of the two daughter cells. A key player in this process is the microtubule-severing enzyme spastin that localizes at the midbody where its activity is crucial to cut microtubules and culminate the cytokinesis. Recently, … WebCytokinetic abscission: cellular dynamics at the midbody Patrick Steigemann and Daniel W.

Midbody abscission
Did you know?
It was long assumed that the midbody was simply a structural part of cytokinesis, and was totally degraded with the completion of mitosis. However, it is now understood that post-abscission, the midbody is converted into an endosome-like signalling molecule, and can be internalised by nearby cells. This … Meer weergeven The midbody is a transient structure found in mammalian cells and is present near the end of cytokinesis just prior to the complete separation of the dividing cells. The structure was first described by Walther Flemming in … Meer weergeven The midbody structure contains bundles of microtubules derived from the mitotic spindle which compacts during the final stages of cell division.
