Stratum basale, also known as stratum germinativum, is the deepest layer, separated from the dermis by the basement membrane (basal lamina) and attached to the basement membrane by hemidesmosomes.

What is the main function of the stratum basale?

Stratum basale, also known as the basal cell layer, is the innermost layer of the epidermis. This layer contains column-shaped basal cells that are constantly dividing and being pushed toward the surface. The stratum basale is also home to melanocytes that produce melanin (the pigment responsible for skin color).

Where is the stratum basale and why is it important?

The stratum basale, also called the stratum germinativum, is the basal (base) layer of the epidermis. It is the layer that's closest to the blood supply lying underneath the epidermis. This layer is one of the most important layers of our skin.
