Anaplasia is defined by the presence of all of the following: multipolar polyploid mitotic figures, marked nuclear enlargement, and hyperchromasia.

(Anaplastic Renal Wilms Tumor, NCI Thesaurus)

Agents that modulate the activity of mitotic enzymes, specifically those that inhibit cytokinesis, may produce an anti-mitotic effect resulting from the aberrant formation of abnormal or polyploid cells and their subsequent exit from mitosis, which triggers apoptosis-an effect unrelated to the classical mitotic arrest described with other anti-mitotic compounds.
