Methods: Human epidermal melanocytes were treated with MSF and examined for its adhesion to bovine serum fibronectin-coated culture plate and for its migration into micropore filters, which were then compared with those of untreated control. Results: Compared with the control, MSF treated melanocytes were easier to adhere to the dishes and move into the filters in a dose-dependent manner, but when the dose of MSF was higher than 150 μg/ml, the adhesion and migration could not be significantly increased. And it was noticed that when the concentrations of MSF was 10μg/ml, significant statistical difference did show between the migration of the treated and untreated melanocytes ( P<0.05) though the adhesion was not increased significantly. Conclusion: MSF had the ability to affect melanocyte adhesion and migration. This could explain, in part, the mechanism of MSF in curing vitiligo lesions.展开更多
