Cultured melanocyte grafting

Autologous cultured epidermal cell grafting is a technique where melanocytes grown in the laboratory are grafted onto areas of pigment loss, after surgically removing the epidermis from the involved area.  With this technique, pigment cells are grown from skin obtained from a punch biopsy specimen usually behind the ear.  

 

The facilities for culture however are expensive, available at few centres, and need technical support.
