Mitotic index obtained after 72 h of exposure to the corresponding Biology Diagrams The mitotic index, a fundamental measure in cell biology, provides insights into the growth and proliferation of cells. It quantifies the percentage of cells undergoing active cell division, known as mitosis.
While mitotic index and Ki-67 can both be used to measure cell proliferation, it is important to recognize that Ki-67 positively stains nuclei in G1, G2, or S phase, which is usually considerably longer and more variable than the M phase. Mitotic Index is a calculation that can be done to determine how actively a group of cells is dividing. In order to calculate the Mitotic Index of a sample, you first count the number of cells that are actively dividing (cells that are in Prophase, Metaphase, Anaphase, or Telophase).

Revision notes on Calculation of Mitotic Index for the Edexcel International A Level Biology syllabus, written by the Biology experts at Save My Exams. Spread the loveIntroduction The mitotic index is a vital parameter used to measure the proliferation of cells in a given sample. It represents the percentage of cells undergoing mitosis, providing key insights into cell division and growth. The calculation of the mitotic index is essential for various scientific and clinical studies, such as developing cancer treatments and understanding
The mitotic index is a measure of cellular proliferation. [1] It is defined as the percentage of cells undergoing mitosis in a given population of cells. Mitosis is the division of somatic cells into two daughter cells. Durations of the cell cycle and mitosis vary in different cell types. An elevated mitotic index indicates more cells are dividing. In cancer cells, the mitotic index may be

Moreover, mitotic activity correlates to cellular growth activity. The simplest and classical method to measure mitotic activity (mitotic index (MI)), is the manual counting of mitotic cells among a given cell population of interest. The latter can be accomplished via phase contrast microscope observation.
