Oxidative damage of H_2O_2 on cultured melanocyte of vitiligo

Objective To study the effect of H_2O_2 on the cultured melanocytes and the relationship between oxidative stress and vitiligo.Method Melanocytes were cultured with H_2O_2,the proliferation and melanogenesis of melanocyte were analysed by MTT and NaOH assay.Result H_2O_2 can inhibite the proliferation and melanogenesis of melanocytes,and the inhibition was concentration and-time-dependent.Conclusion Oxidative stress can inhibite the proliferation and melanogenesis of melanocytes,but oxidative damage can not induce vitiligo.
