What does the autologous melanocyte transplantation procedure involve?

This procedure begins with harvesting a small, thin skin sample from a healthy, pigmented area of your body, typically the thigh or buttock. In a laboratory, the melanocytes (pigment-producing cells) are isolated and cultured to increase their number over several weeks. The resulting cell suspension is then applied to the depigmented patches, which have been prepared by gentle dermabrasion to create a receptive bed. The entire process, from biopsy to transplantation, usually spans 1–2 weeks, with the cultured cells being applied in a single session.
