• increased centrosome number is likely a consequence of polyploidy caused by cells failing to go through cytokinesis
|
• increased frequency of multinucleation in tamoxifen-treated mouse embryonic fibroblasts due to aborted cytokinesis
|
• tamoxifen-treated mouse embryonic fibroblasts exhibit defects in the organization of the cleavage furrow, increased frequency of multinucleation due to aborted cytokinesis and increased centrosomes number likely a consequence of polyploidy compared with control cells
• however, complementation with the wild-type protein rescues cytokinesis defects
