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.
Keratinocyte is the most common epidermal cell. The youngest keratinocytes starts in the layer of the epidermis called Stratum Basale. The cells in this level divides rapidly. Each time the cell divides, one daughter cell is pushed into the cell layer just above to begin its specialization into a mature keratinocyte. The other daughter cell remains in the basal layer to continue to produce new keratinocyte.
