Superficial blood vessels lie beneath the lining cells. The cells are attached to each other and to the overlying stratum spinosum cells by desmosomes and hemidesmosomes. The cells also bind keratin filaments together. Stratum basale (also called the basal cell layer of the epidermis) Stem cells of the epidermis (their daughter cells migrate upwards and differentiate into other cells) Melanocytes and Merkel cells are also located in this layer.
