the ratio of cells in a tissue that are undergoing mitosis, often expressed as either the number of cells in a specified area of tissue section or as a percentage of the total cell sample.
the number of cells per unit (usually 1000 cells) undergoing mitosis during a given time. The ratio is used primarily as an estimation of the rate of tissue growth.
mitotic indexThe percentage of cells in a population that are actually undergoing MITOSIS. The mitotic index is a measure of the reproductive or growth activity of a tissue.
pertaining to mitosis.
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.
the condensed chromosomes by which a cell that is undergoing mitosis can be identified.
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.
mitotic metaphase chromosomes
chromosomes in metaphase manifesting as mitotic figures.
failure of proper disjunction of the paired chromosomes during metaphase which results in the chromosomal abnormalities of monosomy or trisomy.
estimate of the cell's potential reproductive capacity.
