PEG-CeONP-carried hUCMSCs resisted ROS-mediated apoptosis. A Representative fluorescence images of mitochondrial potential measured by JC-1 staining and mean fluorescence intensity (n = 3). B WB assays and Semi-quantitative analysis of BAX and BCL2 in NC, PEG-CeONPs, H₂O₂ and PEG-CeONPs + H₂O₂ groups (n = 3). C Annexin V/PI staining and cytometry indicated analysis to assess the percentage of apoptotic cells (n = 3). NS means not significant versus NC, **p < 0.01 versus NC, ^#p < 0.05 versus H₂O₂, ^##p < 0.05 versus H₂O₂
