Cytokinesis multinucleated
WebTo determine which stage of cytokinesis is affected and to rule out increased cell fusion events, which have been reported for stomatin and can also lead to multinucleated cells, (11) we performed time-lapse microscopy of stomatin-depleted HeLa cells expressing cell division markers GFP-tubulin and mCherry-H2B ( Movies S1 and S2 ). WebJun 1, 2024 · Cycles with absent or incomplete karyokinesis can both yield increased nuclear size and ploidy. Cycles with full nuclear division but incomplete cytokinesis, as well as cell–cell fusion, increase the number of nuclei. Each blue arrow represents a doubling in genome content. Each black arrow represents an incomplete cytokinesis.

WebMay 7, 2024 · Classically, the decision whether to divide further is made after cell division is completed by cytokinesis and can be triggered by intrinsic or extrinsic factors. … WebDec 17, 2013 · Multinucleated Reed-Sternberg (RS) cells are pathognomonic for classical Hodgkin lymphoma (HL), and their presence is essential for diagnosis. How these giant tumor cells develop is controversial, however. It has been postulated that RS cells arise from mononucleated Hodgkin cells via endomitosis.
WebHow could such multinucleated cells be explained? A) The cells underwent repeated cytokinesis but no mitosis. B) The cells had multiple S phases before it entered mitosis. C) The cells did not enter mitosis. D) The cells underwent repeated mitosis, but cytokinesis did not occur. E) The cells underwent repeated mitosis with simultaneous cytokinesis. WebAug 19, 2024 · Karyogamy is the fusion of nuclei and leads to the production of a diploid zygote. The zygote will grow, replicating the nuclei with no cytokinesis, to form the multinucleate plasmodium. A mature plasmodium (multinucleated free-flowing mass of protoplasm) can produce sclerotium (small cells) in a dry habitat. Summary
WebMultinucleated cells could be also induced by 12-O-tetradecanoylphorbol 13-acetate (TPA) in 5F9A cells. This effect was mediated by protein kinase C. Possible mechanisms of multinucleation by TPA were hypothesized to be either karyokinesis without cytokinesis or … WebMar 27, 2024 · Time-lapse microscopy revealed that strong RNA interference (RNAi)-mediated silencing of KIF14 induced cytokinesis failure, causing several rounds of endoreduplication and resulting in multinucleated cells. Additionally, less efficacious KIF14-specific short interfering RNAs (siRNAs) induced multiple phenotypes, all of which …
