1. How the cells of the epidermis get oxygen and nutrients? Since the epidermis does not have a direct blood supply, all nutrients come from the diffusion from blood capillaries extending from the upper layers of the dermis. Only the cells of the stratum basale receive nourishment, the cells that are pushed away in the regeneration process die as a result.
