Anti-wrinkle Effect of AdMSCs-CM in Photoaging Skin Model of Hairless Mice

요약 : 

The purpose of this study was to investigate the anti-wrinkle effect of adipose-derived mesenchymal stem cell-conditioned medium (AdMSCs-
CM) in a UVB irradiation-induced hairless mouse wrinkle model. Mice treated with AdMSCs-CM showed improvements in transepidermal water loss (TEWL), water capacity and erythema index of skin. The AdMSCs-CM treated mice showed reduced total wrinkle area, number, length and depth, as measured by gross observation and replica image analysis, and had a thinner epidermis and increased collagen and elastic fiber content, compared with the UV control group, as measured by histopathological examination. The activity of AdMSCs-CM was further confirmed by the reduction in MMP-3 mRNA expression and MMP-2, 9 protein activity in the skin of the AdMSCs CM treated animals. These results suggested that AdMSCs-CM may be effective in the treatment of wrinkles by protecting of the collagen from degradation induced by UV irradiation. Further studies about detailed mechanisms of action of AdMSCs-CM will be needed
