Effect of H2O2 treatment and recovery on aging hCB-ECs. hCB-EC permeability increases with increasing population doublings and after H2O2 treatment. The low passage hCB-ECs recover from the stress 24 hours after treatment, while the higher passage hCB-ECs do not. For each experiment, 8 replicates were performed (n=3). *:p<0.05 compared to untreated control of same population doubling; +:p<0.05 compared to 22 population doubling untreated control.
