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 ). WebFew cells such as the skeletal muscle cells are multinucleated cells because after the process of mitosis, cell division in them stops and the cell does not go through cytokinesis, thus producing more than one nucleus. During cancer or viral diseases, the cell cycle of these cells become unregulated.

WebTo better understand the mechanisms underlying cytokinesis B and C, we introduced mutations into mhcA- cells and isolated clones that consistently gave rise to large, multinucleated cells. One such clone was found to have a disrupted talA gene, which codes for one of two Dictyostelium homologues of talin. WebAug 14, 2012 · To determine whether NAC1 was essential for effective cytokinesis, we reintroduced NAC1 expression in Nac1-null cells to determine whether ectopic NAC1 would prevent the multinucleated phenotype.

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 smart canadians

"Multinucleate cells (also known as multinucleated or polynuclear cells) are eukaryotic cells that have more than one nucleus per cell, i.e., multiple nuclei share one common cytoplasm. Mitosis in multinucleate cells can occur either in a coordinated, synchronous manner where all nuclei divide simultaneously or asynchronously where individual nuclei divide independently in time and space. Certain organisms may have a multinuclear stage of their life cycle. For example, slime molds h… " - Cytokinesis multinucleated
