The anatomical relationship between keratinocytes and melanocytes is known as 'the epidermal melanin unit' and it has been estimated that each melanocyte is in contact with â¼40 keratinocytes in the basal and suprabasal layers.. Translated: Melanocytes produce melanin in nice little packages called, melanosomes.
The keratinocytes originate from human epidermal stem cells present in the stratum germinativum (basal layer of epidermis). The progeny of these stem cells are termed transit amplifying (TA) cells. TA cells also reside in the basal layer and undergo mitosis.s the granulosum keratinocytes are pushed into lucidum layer, they become transparent or translucent and get flattened. The lucidum keratinocytes may be 3-5 layers in thickness and may undergo apoptosis releasing fatty substance. They contain a clear intermediate form of keratin called eleidin.
