WebMar 21, 2024 · Abscission is the final step of cytokinesis and results in the physical separation of two daughter cells. In this study, we conducted a time-resolved series of electron tomographic reconstructions to define the steps required for the first embryonic abscission in Caenorhabditis elegans. WebSep 1, 2024 · We visualize MT bridges connecting pairs of cells and show that the cytokinetic bridge does not undergo stereotypical abscission after cell division. Instead, it serves as scaffold for the accumulation of the MT minus-end–stabilizing protein CAMSAP3 throughout interphase, thereby transforming this structure into a noncentrosomal MTOC.
