Stratum basale: melanocytes
Melanocytes in stratum basale synthesize melanin pigment in vesicles called melanosomes. Once formed, these vesicles migrate into melanocyte processes and are transferred to neighboring keratinocytes. Once in keratinocytes, melanin distributes to a supranuclear location, blocking ultraviolet radiation. 10,000x
