TEM #11-5 (Skin Human in the Stratum Basale, X17,300)- These cells lie on the basal lamina (2) which comprises the upper most layer of the basement membrane (6). The keratinocytes in this layer are actively dividing cells which contain keratin filaments (organized into tonofibrils) (4) and demosomes. These cells also contain a number of melanin granules which they have phagocytized from melanocytes.
