It is not well defined whether dermis-derived factors regulate the proliferation and differentiation of human melanocytes.
PDGF-BB stimulated the proliferation of cultured melanoblasts, but inhibited the proliferation of melanocytes.
PDGF-BB promoted melanocyte differentiation through the stimulation of the expressions of tyrosinase and tyrosinase-related protein-1.
PDGF-BB regulates the proliferation and differentiation of human melanocytes in a differentiation-stage-specific manner.
