(A) Summary of the evaluation of the mitotic index. In three independent experiments, about 100 cells were counted and the number of mitoses therein was determined after Aurora-A immunofluorescence staining. The table also provides mean and ± standard deviation of the percentage of mitoses. (B) Summary of the evaluation of the index of multipolar mitoses.
