Abstract:

The aim of this study was to investigate the effect of TGF-β3 on the phenotype of alpaca melanocyte cultured in vitro.The melanocyte proliferation,gene expression of MITF,TYR and TYRP2 at the transcript and translation level were detected and melanin production was analyzed after the addition of TGF-β3 with different concentrations of 6.25,12.5,25,50 ng•mL-1 in melanocyte medium.The results showed that:Compared to the normal melanocyte,the proliferation of melanocytes was inhibited within 30 h by the addition of 50 ng•mL-1 TFG-β3 and then the amount of cells could be maintained without dependence on the concentration of TGF-β3 after 30 h; MITFTYR and TYRP2 expression were down-regulated and melanin production also reduced after the addition of TGF-β3.The dose of 50 ng•mL-1 TGF-β3 caused more significant effects.The results suggested that TGF-β3 had the important effects on the biology of alpaca melanocyte by regulating the expression of MITFTYRTYRP2 and melanin production.
