PEG-CeONPs-carried hUCMSCs resisted to apoptosis and senescence through NFκB and MAPK signaling pathway. A WB analysis of IκBα, P-IκBα, P65, P-P65, BAX, BCL2, P16 and P21 in hUCMSC treated with PEG-CeONPs, H₂O₂ and TNFα (n = 3). B WB analysis of JNK, P-JNK, P38, P-P38, BAX, BCL2, P16 and P21 in hUCMSC treated with PEG-CeONPs, H₂O₂ and DE (n = 3). **p < 0.01 versus NC, ^#p < 0.05 versus H₂O₂, ^##p < 0.05 versus H₂O₂, ^$p < 0.05 versus PEG-CeONPs, ^$$p < 0.01 versus PEG-CeONPs. NS means not significant
