Characteristics of OMSCs and UMSCs. a OMSCs and UMSCs were stained for senescence associated β-galactosidase (β-gal) activity. Blue color indicates β-gal positive. b Quantification of β-gal-positive cells out of total cells in A. c Western blot analysis of aging-related protein markers (Sirt1, p53, p21, and p16). Quantification of specified proteins was shown in the bar graph. The values were normalized with GAPDH and then compared with that of UMSCs. d Time-course of cell growth determined by Cell Counting Kit-8 (CCK-8) assay was plotted for OMSCs and UMCSs. Each experiment was repeated three times. *P < 0.05 vs UMSCs
