摘要:

文题释义:

脂肪来源干细胞:是一种从脂肪组织分离提取的成体间充质干细胞,可自我更新并分化为脂肪细胞、软骨细胞、肌肉细胞、成骨细胞、神经细胞等细胞谱系。
衰老:机体从构成物质、组织结构到生理功能的丧失和退化过程。近来在动物体内已发现一些与衰老有关的基因,例如p21和p27基因对细胞衰老进程有重要影响。

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. 

Key words: adipose-derived stem cell, adipose tissue, young, old age, mouse, anti-aging
