Structure and Function: 95% of the cells in the epidermis are keratinocytes. These cells are found in the basal layer of the stratified epithelium that comprises the epidermis, and are sometimes referred to as basal cells, or basal keratinocytes.quamous keratinocytes are also found in the mucosa of the mouth and esophagus, as well as the corneal, conjunctival, and genital epithelia. These cells are responsible for forming tight junctions with the nerves of the skin. They also keep Langerhans cells of the epidermis, and lymphocytes of the dermis, in place.
