Wnt Modulators, Secreted Frizzled Related Protein (sFRP) 2 and Wnt Inhibitory Factor (WIF)-1, Stimulate Melanogenesis in Normal Human Melanocytes
… studies showed that hyperpigmentary skins of melasma express high levels of frizzled-related protein 2 (sFRP2) and Wnt inhibitory factor-1 (WIF-1) compared to perilesional normal skins. In this study, I investigated the functional roles of sFRP2 and WIF-1 on skin pigmentation. The present …
