Pertaining to mitosis.
- m. activity — degree to which a cell population is proliferating; used as an index of tumor aggression. Can be quantified by counting the percentage of cells showing mitotic figures, or by flow cytometry.
- m. figure — the condensed chromosomes by which a cell that is undergoing mitosis can be identified.
- m. index — the percentage of cells simultaneously in the process of division, normally calculated after counting 1000 cells. Used in morbid pathology as a measure of the malignancy of a tumor, and in clinical pathology as an index of survival time of a neoplasm.
- m. metaphase chromosomes — chromosomes in metaphase manifesting as mitotic figures.
- m. nondisjunction — failure of proper disjunction of the paired chromosomes during metaphase which results in the chromosomal abnormalities of monosomy or trisomy.
- m. potential — estimate of the cell's potential reproductive capacity.
