a The ability of all groups of PBMSCs to form clones was tested by cell colony formation assays and crystal violet staining. b Quantitative analysis of the number of cell clones in (a). c The growth curve of all groups of PBMSCs at 1, 2, 3, 4, 5, 6, and 7 d. d The viability of PBMSCs after 70 days of culture was tested by the MTS method. e Cell morphology senescence-associated β-galactosidase staining (black arrowheads) in PBMSCs from all groups. Scale bars = 100 µm. f Quantitative analysis of the ratio of senescent PBMSCs to total PBMSCs in (e). g The apoptosis level of all groups of PBMSCs was detected by flow cytometry using Annexin V/PI staining. All graphical data are shown as the means ± SEMs. P < 0.05: * vs. the vehicle group, # vs. the oeβ-catenin group, Δ vs. the shβ-catenin group, n = 10 in each group.
