The area provides a reference unit, for example in reference ranges for urine tests. [3]Used for grading of soft tissue tumors: Grading, usually on a scale of I to III, is based on the degree of differentiation, the average number of mitoses per high-power field, cellularity, pleomorphism, and an estimate of the extent of necrosis (presumably a reflection of rate of growth).
An elevated mitotic index indicates more cells are dividing. In cancer cells, the mitotic index may be elevated compared to normal growth of tissues or cellular repair of the site of an injury. [2] The mitotic index is therefore an important prognostic factor predicting both overall survival and response to chemotherapy in most types of cancer ...
Cells in the mitotic phase are identified by the typical appearance of their chromosomes in the cell during the mitotic phase of the cell cycle. [4] Usually the number of mitotic figures is expressed as the total number in a defined number of high power fields, such as 10 mitoses in 10 high power fields.

English: M–Cdk activity promotes the events of early mitosis, resulting in the metaphase alignment of sister chromatids on the spindle. M–Cdk activity also promotes the activation of APCCdc20, which triggers anaphase and mitotic exit by stimulating the destruction of regulatory proteins, such as securin and cyclins, that govern these events.
The Ki-67 protein (also known as MKI67) is a cellular marker for proliferation, [10] and can be used in immunohistochemistry. It is strictly associated with cell proliferation . During interphase , the Ki-67 antigen can be exclusively detected within the cell nucleus , whereas in mitosis most of the protein is relocated to the surface of the ...
