Abstract The culture lifetime of epidermal cells of newborn humans is increased from 50 to 150 generations by adding to the medium epidermal growth factor, a polypeptide mitogen. EGF seems to delay senescence of the cells by maintaining them in a state further removed from terminal differentiation. This effect is revealed by a greater ability of the cells to survive subculture and initiate new colonies, but not necessarily by an increased growth rate.
