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.
Keratinocytes = cells of the skin producing keratin; so called prickle or MALPIGHIAN cells. Stratum basale = basal layer. is, together with the stratum spinosum, responsible for cell reproduction in this layer; this layer consists of tall cylindrical cells (Epitheliocytus basalis) and melanocytes.tratum spinosum = prickle cell layer. is multi-layered and consists of polygon-shaped cells joined together by desmosomes (visible in the electron microscope as thickening of the cell membrane). In this layer the keratinocytes are joined by tonofibrils (a filament of proteins) like a network.
