To address the effect of hUCB-MSC-CM on melanogenesis, both Melan-a melanocytes and B16F1 melanoma cells were stimulated with α-MSH, and the cells were further treated with CM derived from bone marrow-MSCs (BM-MSCs), adipocyte-MSCs, human epidermal keratinocytes-MSCs (HEK-MSCs) as well as hUCB-MSCs. Here, STAMBP is linked to melanoma.
