摘要

背景:脂肪来源干细胞具有抗衰老的作用,但来自不同年龄供者的脂肪来源干细胞是否有区别,还需深入研究.目的:对比老年和年轻小鼠脂肪来源干细胞的生物学特性.方法:分别从8周龄、14周龄C57BL小鼠脂肪组织中提取脂肪来源干细胞,对比分析老年和年轻小鼠脂肪来源干细胞的细胞周期、凋亡、增殖能力的差异,定量PCR和Western blot检测老年和年轻小鼠脂肪来源干细胞衰老相关P21、P27基因和蛋白的表达.结果与结论:与老年小鼠脂肪来源干细胞相比,年轻小鼠脂肪来源干细胞更有活力,形态更规则,凋亡更少,增殖更快,衰老相关P21、P27基因和蛋白表达量更低,说明年轻小鼠脂肪来源干细胞具有更好的抗衰老作用.

Abstract

BACKGROUND:Adipose-derived stem cells have anti-aging effects,but whether adipose-derived stem cells from donors of different ages are different needs further study.OBJECTIVE:To compare the biological properties of adipose-derived stem cells in old and young mice.METHODS:Adipose-derived stem cells were extracted from adipose tissue of C57BL mice aged 8 and 14 weeks,respectively.The differences of cell cycle,apoptosis,and proliferation of adipose-derived stem cells in old and young mice were compared.The expression levels of aging-related P21 and P27 genes and proteins of adipose-derived stem cells in old and young mice were detected by quantitative PCR and western blot assay.RESULTS AND CONCLUSION:Compared with old mouse adipose-derived stem cells,young mouse adipose-derived stem cells were more active,more regular in morphology,less apoptosis,faster proliferation,and lower in expression of age-related P21 and P27 genes and proteins.It has been proven that adipose-derived stem cells from young mice have better anti-aging effects.
