BACKGROUND: Treatment of depigmented skin is an unmet medical need. OBJECTIVE: Melanocytes or stem cells thereof residing in the outer root sheath (ORS) of hair follicles might be used to repigment skin. METHODS: After de-epidermisation, autologous ORS cell solutions were applied to 5 patients with vitiligo and 1 with leucoderma. RESULTS: Stable repigmentation in a variable percentage was documented in all the patients. CONCLUSION: Applying ORS-derived melanocytes is a promising technology to improve autologous melanocyte transplantation.
