Compositions and methods for generating melanocytes through direct reprogramming are disclosed. Also disclosed are methods of use of such compositions for the treatment of vitiligo and other hypopigmentation disorders. In accordance with the present invention, a method for producing melanocytes suitable for use in human patients is provided. An exemplary method comprises providing cells capable of transdifferentiation into melanocytes, culturing said cells in a chemically defined culture medium, introducing at least two of microphthalmia-associated transcription factor (MITF), SRY-related HMG-box (SOX10) transcription factor and paired box-3 (PAX-3) transcription factor and paired box-3 (PAX-3) transcription factor, or nucleic acids encoding said transcription factors into said cells, wherein expression of said factors induces the cells to transdifferentiae into melanocytes expressing melanocyte markers TYR, DCT, S-100 and Melan-A.
