[Retracted] Hypoxia-Activated PI3K/Akt Inhibits Oxidative Stress via the Regulation of Reactive Oxygen Species in Human Dental Pulp Cells

Figure 2

HP changed the cell phenotypes of hDPCs after culture under normoxia, hypoxia, and reoxygenation: (a) western blot assay and quantitative analysis of the expression of HIF-1α under normoxia and hypoxia at 0 h, 4 h, 8 h, 12 h, 24 h, and 48 h of culture; (b) proliferation ability of hDPCs in each group; (c) flow cytometry and quantitative analysis of cell cycle distribution in hDPCs after 3 d of culture under different oxygen concentrations; (d) colony-forming units and quantitative analysis in hDPCs after 10 d of culture; (e) expression of the mesenchymal stem cell surface markers CD133, CD34, CD105, and OCT4 in each group. Statistical significance is shown as .
