Stratum basale: melanocytes

Melanocytes, identified by their clear cytoplasm and heterochromatic nuclei, synthesize melanin-containing melanosomes, which are transferred to the keratinocytes of stratum basale.  Some melanosomes are retained in keratinocytes as these cells migrate upward.  Stratum spinosum is much thinner in this thin skin than it is in thick skin.  1000x
