Deepest dividing epitheial layer of the skin?

The deepest dividing epithelial layer of the skin is the stratum basale, also known as the basal layer. It is composed of a single row of columnar or cuboidal keratinocytes that undergo mitosis to produce new skin cells. This layer is crucial for the regeneration of the epidermis and contains melanocytes, which produce melanin, contributing to skin pigmentation. Additionally, it is anchored to the underlying dermis by the basement membrane.
