Dermatology
In the stratified squamous epithelium of the skin, the basal cells of the epidermis (stratum basale) give rise by unequal division to other basal cells (BCs) and to cells that progress through the spinous, granular and horny layers, becoming increasingly keratinised; the outermost cells eventually slough as squames.

Olfaction
In the olfactory mucosa, BCs give rise to olfactory and sustentacular cells.

Urology
In epididymal cells, the function of BCs is unclear; they likely serve as urothelial stem cells.
