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 divide in the skin's mitotic layer. The innermost part of the epidermis, this is made up of a single line of keratinocytes held together and to the underlying dermis by desmosomes, a sort of press stud structure. Each keratinocyte divides to produce two identical daughter cells.erkel cells (6-10% of the cells in the epidermis), situated between the keratinocytes in the renewal layer, remain in contact with a nerve ending. They can be isolated or grouped together in clusters called Merkel corpuscles.
