Those keratinocytes found in the basal layer of the skin are sometimes referred to as basal cells or basal keratinocytes.
Keratinocyte is the most common epidermal cell. The youngest keratinocytes starts in the layer of the epidermis called Stratum Basale. The cells in this level divides rapidly. Each time the cell divides, one daughter cell is pushed into the cell layer just above to begin its specialization into a mature keratinocyte. The other daughter cell remains in the basal layer to continue to produce new keratinocyte.
