Mitotic somatic cells taken from aged individuals can often show robust population doubling rates.

Question

Quizplus · Accepted Answer

Mitotic somatic cells from aged individuals can still show robust population doubling rates because their capacity for division is not solely determined by the age of the organism but also by the intrinsic properties of the cells and their environment. Aging can affect the rate of cell division and senescence in a population of cells, but it does not universally halt their ability to divide, especially in controlled laboratory conditions where factors promoting cell division can be optimized.
