Our previous study found that white adipose stem cells (W-ASCs) derived from abdominal and femoral sulcus white adipose stem cells (ASCs) have antiaging and age-related obesity effects. Whether interscapular brown adipose stem cells (B-ASCs) have the same effect has not been reported. The study objective was to compare the effects of ASCs from different tissues on aging and aging-related obesity.
C57BL/6J mice at 22 months of age were transplanted with either B-ASCs or W-ASCs from young mice at 2 months of age. Changes in body weight, biochemistry, cytokines, hormone secretion, cell senescence, lipid metabolism, and ASC function were assessed after transplanted 1 month.
W-ASCs were superior to B-ASCs as aging and age-related obesity indicators, based on change in body weight, organ weight, antioxidant and anti-inflammatory activity, lipid metabolism, and liver and kidney function.
Difference in the tissue source was reflected by the heterogeneity of antiaging and age-related obesity effects of transplanted ASCs. Based on the study results, we recommend W-ASCs over B-ASCs in aging and age-related obesity applications.
我们之前的研究发现,源自腹部和腹股沟沟白色脂肪干细胞(ASCs)的白色脂肪干细胞(W-ASCs)具有抗衰老和抗年龄相关性肥胖的作用。肩胛间棕色脂肪干细胞(B-ASCs)是否具有同样的作用尚未见报道。本研究的目的是比较不同组织来源的ASCs对衰老及衰老相关肥胖的影响。
将2月龄幼鼠的B-ASCs或W-ASCs移植到22月龄的C57BL/6J小鼠体内。移植1个月后评估体重、生化指标、细胞因子、激素分泌、细胞衰老、脂质代谢及ASC功能的变化。
基于体重变化、器官重量、抗氧化和抗炎活性、脂质代谢以及肝肾功能,在衰老和年龄相关性肥胖指标方面,W-ASCs优于B-ASCs。
移植的ASCs抗衰老和抗年龄相关性肥胖作用的异质性反映了组织来源的差异。基于研究结果,在衰老和年龄相关性肥胖应用中,我们推荐使用W-ASCs而非B-ASCs。
