The first three strata of the epidermis consists of living keratinocytes and the most superficial strata contain dead keratinocytes.
Keratinocytes are the most common cell type in the epidermis, the outermost layer of the skin, accounting for over 90% of all cells. They begin in the epidermis's deepest layer, the stratum basale, and progress to the skin's last barrier layer, the stratum corneum.
The stratum basale (germinatum) is the innermost (deepest) layer of the epidermis, followed by the stratum spinosum, stratum granulosum, stratum lucidum (when present), and the stratum corneum, which is the outermost layer.
