Effect of overexpression of keap1 on hucMSCs cell proliferation. A Crystalline violet staining as well as quantitative detection at 570 nm, scale bar: 100 μm. p = 0.0038. B CCK8 detected cell viability. n = 15. p < 0.0001. C, D PI staining was used to measured cell cycle and the proportion of S phase was quantified. p = 0.0016. E CyclinD1 protein level was detected by WB and quantified. p = 0.0121
