In previous work we described a novel culture technique using a cholera toxin and PMA-free medium Mel-mix for obtaining pure melanocyte cultures from human adult epidermis.
In Mel-mix medium the cultured melanocytes are bipolar, unpigmented and highly proliferative. Further characterization of the cultured melanocytes revealed the disappearance of c-Kit and TRP-1 and induction of nestin expression, indicating that melanocytes dedifferentiated in this in vitro culture.
These dedifferentiated, easily accessible cultured melanocytes provide a good model for studying melanocyte differentiation and possibly transdifferentiation. Because melanocytes in Mel-mix medium can be cultured with human serum as the only supplement, this culture system is also suitable for autologous cell transplantation.

Competing interests: The authors have declared that no competing interests exist. In vertebrates, melanocytes arise from the neural crest [1]. Melanoblasts are unpigmented cells containing only immature melanosomes that lack functional tyrosinase, the critical enzyme of melanin synthesis [2].
Fully differentiated melanocytes characterized by tyrosinase TYR , tyrosinase related protein-1 and -2 TRP-1 and TRP-2 activities as well as by numerous mature melanosomes and well-developed dendrites, are located mainly in the epidermis, dermis and hair bulb [3].
