Stratum corneum
Stratum corneum consists of squamous cells containing keratin protein surrounded by a thickened plasma membrane. These cells are continuously shed from the surface of the epidermis and are replenished through the upward migration and ongoing keratinization of epidermal keratinocytes. Stratum lucidum does not form a discrete layer in thin skin, shown here. 400x
