Stratum basale |
The Stratum germinativum (or basal layer, stratum basale) is the deepest layer of the epidermis, a continuous layer of cells often described as one cell thick, though it may be two to three cells thick in glabrous skin and hyperproliferative epidermis.1 The basal cells of this layer can be considered the "stem cells" of the epidermis, undifferentiated, proliferating, and creating daughter cells that migrate upward, beginning the process of differentiation.2
