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.
