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.
Mitotic trigger waves are waves of Cyclin-dependent kinase 1 activity in cells that originate from pacemaker regions of the nucleus and propagate through the cytoplasm. [1]. Because trigger waves do not decrease in speed or amplitude during their propagation, they are more reliable at conveying molecular information across greater distances ...
W3Schools is a freemium educational website for learning coding online. [1] [2] Initially released in 1998, it derives its name from the World Wide Web but is not affiliated with the W3 Consortium. [3] [4] [unreliable source] W3Schools offers courses covering many aspects of web development. [5] W3Schools also publishes free HTML templates.
In mathematics, the Fox H-function H(x) is a generalization of the Meijer G-function and the Fox–Wright function introduced by Charles Fox . It is defined by a Mellin–Barnes integral H p , q m , n [ z | ( a 1 , A 1 ) ( a 2 , A 2 ) …
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.
The different stages of mitosis altogether define the mitotic phase (M phase) of a cell cycle—the division of the mother cell into two daughter cells genetically identical to each other. [3] The process of mitosis is divided into stages corresponding to the completion of one set of activities and the start of the next.
Mitogens can be either endogenous or exogenous factors. Endogenous mitogens function to control cell division is a normal and necessary part of the life cycle of multicellular organisms. For example, in zebrafish, an endogenous mitogen Nrg1 is produced in response to indications of heart damage. When it is expressed, it causes the outer layers ...
Cell synchronization is a process by which cells in a culture at different stages of the cell cycle are brought to the same phase. Cell synchrony is a vital process in the study of cells progressing through the cell cycle as it allows population-wide data to be collected rather than relying solely on single-cell experiments.
