Histologic image showing a section of epidermis.<unk>  labeled near bottom. The<unk>  <unk> layer, sometimes referred to as<unk>  germinativum) is the deepest layer of the five layers of the epidermis, the external covering of skin in mammals. The<unk>  is a single layer of columnar or cuboidal<unk> cells. The cells are attached to each other and to the overlying<unk>  spinosum cells by desmosomes and hemidesmosomes. The nucleus is large, ovoid and occupies most of the cell. Some<unk> cells can act like stem cells with the ability to divide and produce new cells, and these are sometimes called<unk> keratinocyte stem cells. Others serve to anchor the epidermis glabrous skin (hairless), and hyper-proliferative epidermis (from a skin disease). They divide to form the keratinocytes of the<unk>  spinosum, which migrate superficially. Other types of cells found within the<unk>  are melanocytes (pigment-producing cells) and Merkel cells (touch receptors).
