Fig. 4-1 Comparison of skin of Caucasian and Negro. Observe the structure in both sections and see the melanin, which is produced by the melanocytes and transferred to the keratinocytes, appears in the basal cells of the stratum basale. More pigment is present in dark skin than in light skin. The difference is due to more rapid digestion of the pigment by lysosomes of keratinocytes in light skin.
