Summary Introduction
To discuss:
The life history of a keratinocyte by mitosis at the base of the epidermis to the time it exfoliates from the surface.
Introduction:
Epidermis is one of the two layers of skin. It is composed with five types of cells. Stem cells in the basal layer divide and give rise to keratinocytes. Keratinocyte are majority of epidermal cells.
