Cytokinesis multinucleated
Did you know?
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… WebJun 29, 2007 · In this assay, defects in cytokinesis are manifested by the appearance of multinucleated cells. Supporting an essential role in cytokinesis, depletion of Alix resulted in a 14-fold increase in the percentage of multinucleated cells as compared with control cells ( Fig. 2B ).

Some of these multinucleated cells are considered to be neoplastic. The mechanism of neoplastic multinucleation remains unknown, but is considered to be induced by either cell-cell fusion or acytokinetic cell division.
