Cells of the Epidermis. The majority of epidermal cells are keratinocytes that produce a fibrous protective protein called keratin. Melanocytes are epithelial cells that synthesize the pigment melanin. Langerhans cells, or epidermal dendritic cells, are macrophages that help activate the immune system.Merkel cells are associated with sensory nerve endings. Layers of the Epidermis.
