Permeability percent increase due to H2O2 treatment in early passage vs. late passage hCB-ECs. hCB-ECs that underwent 31 or fewer population doublings exhibited an 80% increase in permeability after treatment with H2O2. The hCB-ECs that underwent at least 57 population doublings only had a 37% increase in permeability after treatment with H2O2. The younger hCB-ECs were more affected by the oxidative stress than the aged hCB-ECs. For each experiment, 8 replicates were performed from 3 different donors; *:p<0.05 compared to untreated control; #p<0.01 compared to untreated control.
