The formulae that have been used to calculate population growth rates from fractions of cells undergoing mitosis are quite diverse (Table 1) and often of un- clear origin.
Webthe number of cells in mitosis and the total number of cells. •The percentage of cells undergoing mitosis or it is defined as the ratio of no. of cells in the dividing phase to the total number of cells observed. This will help to identify the region of most mitotic activities. Mitotic index help us to quantify the cell division. WebAlthough mitotic rate can be effectively categorized in 3 groups (1/mm2, 1/mm2(-4)/mm2, and > 4/mm2), the optimal way to use mitotic rate remains unclear, and even this simplification requires determining the raw number per square millimeter.
