ke·rat·i·no·cyte (kə-ratґĭ-no-sīt) an epidermal cell that synthesizes keratin; about 95 per cent of the cells of the epidermis are of this type. They and the melanocytes form the binary cell system of the epidermis. In its successive stages, the keratinocyte is known as basal cell, prickle cell, and granular cell. Called also malpighian cell.
