basal cell of epidermis
basal cell of epidermis
A mitotically active, columnar-shaped keratinocyte located in the stratum basale of the epidermis and attached to the basement membrane. This cell exhibits heterogeneity, encompassing stem and progenitor subpopulations with distinct molecular and proliferative characteristics (Haensel et al., 2020), and serves as the primary source of new keratinocytes for epidermal renewal, homeostasis, and regeneration.
