  2. Mitotic index - Wikipedia

    en.wikipedia.org/wiki/Mitotic_index

    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.

  3. Proliferative index - Wikipedia

    en.wikipedia.org/wiki/Proliferative_index

    Mitosis in a neuroendocrine tumor. Mitotic indexing is the oldest method of assessing proliferation and is determined by counting the number of mitotic figures (cells undergoing mitosis) through a light microscope on H&E stained sections. It is usually expressed as the number of cells per microscopic field.

  4. Mitotic cell rounding - Wikipedia

    en.wikipedia.org/wiki/Mitotic_cell_rounding

    Thirdly, mitotic rounding has been shown to be important to generate sufficient space and appropriate geometry for proper mitotic spindle function, which is necessary for timely and accurate progression through mitosis. [2] [8] [9] Thus, mitotic cell rounding is involved in tissue organization and homeostasis.

  5. Cell synchronization - Wikipedia

    en.wikipedia.org/wiki/Cell_synchronization

    Mitotic selection is a drug-free procedure for the selection of mitotic cells from a monolayer undergoing exponential growth. [13] During mitosis, cells undergo changes in morphology, and mitotic selection takes advantage of this in adherent cells grown in a monolayer. The cells become more spherical, decreasing the surface area of cell ...

  6. Neuronal cell cycle - Wikipedia

    en.wikipedia.org/wiki/Neuronal_cell_cycle

    Alzheimer diseased neurons rarely exhibit the ability to enter mitosis and, if they don’t undergo rapid mitosis, can survive for long periods of time in a tetraploid state. These neurons are able to enter the S phase and replicate their DNA, however they become blocked in the G2 state.

  8. Cell cortex - Wikipedia

    en.wikipedia.org/wiki/Cell_cortex

    In mitosis, F-actin and myosin II form a highly contractile and uniform cortex to drive mitotic cell rounding. The surface tension produced by the actomyosin cortex activity generates intracellular hydrostatic pressure capable of displacing surrounding objects to facilitate rounding.
