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… WebJan 21, 2016 · A dramatically increase in cell size resulting in the formation of giant multinucleated trophozoites (polykaryon) was also found.

Syncytia can also form when cells are infected with certain types of viruses, notably HSV-1, HIV, MeV, SARS-CoV-2, and pneumoviruses, e.g. respiratory syncytial virus (RSV). These syncytial formations create distinctive cytopathic effects when seen in permissive cells. Because many cells fuse together, syncytia are also known as multinucleated cells, giant cells, or polykaryocytes… 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.
