WebThe centrosomes (centrioles) are organelles responsible for cell division and the assembly of spindle fibers that separate the chromosomes into two sets. When centrosomes are removed, the ability of the cell to divide is impaired. This is one of the reasons why a cancer treatment which stops the cells production of centrosomes works. WebAug 1, 2009 · When cells are exposed to an anti-mitotic agent such as taxol, they arrest in mitosis due to chronic activation of the spindle-assembly checkpoint. They then undergo one of several fates. Cells might die directly in mitosis, or divide unequally to produce aneuploid daughter cells. Alternatively, cells might exit mitosis without undergoing division.
