Effect of HP on oxidative stress in hDPCs after 3 d culture under normoxia, hypoxia, and reoxygenation: (a) HP-treated hDPCs were stained with 10 μM DCFDA and analyzed by flow cytometry; (b) the expression of inflammatory cytokines in each group, as analyzed by ELISA; (c) flow cytometry and quantitative analysis of cell apoptosis ratio in each group; (d) activity of the antioxidant enzymes SOD, CAT, and GSH-PX in hDPCs during culture at different oxygen concentrations. Statistical significance is expressed as .
