摘要：
Background: Mesenchymal stem cells within the stromal-vascular fraction of subcutaneous adipose tissue, adipose-derived stem cells (ADSCs), produced soluble factors and they exhibit diverse pharmacological effects in skin biology. Objective: The present study examines the protective effect of ADSCs for human dermal fibroblasts (HDFs) through anti-oxidation in a tert-butyl. hydroperoxide (tbOOH) induced oxidative injury model. Methods and results: The conditioned medium of ADSCs (ADSC-CM) was harvested and tested for antioxidant action. ADSC-CM had an antioxidant effect as potent as 100 mu M ascorbic acid and various antioxidant proteins were detected in ADSC-CM by proteomic analysis. Morphological change and cell survival assay revealed that incubation with ADSC-CM aided HDFs to resist free radicals induced by tbOOH. In addition, activities of superoxide dismutase and glutathione peroxidase were enhanced in the ADSC-CM treated HDFs which confirmed the study hypothesis that ADSCs protect HDFs through antioxidant action. In a cell cycle analysis, ADSC-CM treatment reversed the apoptotic cell death induced by tbOOH and caused a decrease of sub-G1 cells with respect to untreated cells. The anti-apoptotic effect of ADSC-CM was also reproduced by caspase-3 activity assay. Conclusion: These results suggest that ADSCs have potent antioxidant activity and protect HDFs from oxidative injury by decreasing apoptotic cells. Therefore, ADSCS and ADSC-CM are good candidates for control and prevention of skin damage from free radicals in various skin conditions. (c) 2007 Japanese Society for Investigative Dermatology.
