Abstract:
Objective To investiagte the adipogenic differentiative ability of adipose tissue-derived stromal cells(ADSCs) between the patients with type 2 diabetes mellitus(T2DM) and healthy persons.Methods The adipose tissues were taken from the adipose tissue in T2DM patients and healthy persons for separating and culturing ADSCs.The cells of third generation were taken for inoculation.The difference in cellular phenotype and growth speed were compared between the two groups.Adding adipogenesis inducing fluid,the adipogenic differentiative situation was observed in the two groups.The oil red O was added on 14 d for conducting the cell staining and observation.The oil red O was extracted by isopropanol,and the cellular absorbances were compared between two groups.Meanwhile,the expression of PPAR-γ,C/EBP-α and C/EBP-β on 14 d of adipogenic differentiation were compared between two groups by using qPCR method.Results The cellular phenotype and growth speed of ADSCs had no statisticat difference between T2DM patients and healthy persons.On 14 d of adipogenic differentiation,the oil red O absorbance value of AD-SCs in T2DM patients was significantly higher than that in the healthy persons,and the expression of PPAR-γ,C/EBP-α and C/EBP-β were significantly higher than those in the healthy persons.Conclusion The adipogenic differentiative ability of ADSCs in T2DM patients is obviously higher than that in healthy persons,which may be one of causes easy to be obese in T2DM patients.
