Hypoxia promoted cell proliferation in DPSCs. a CCK8 assays revealed that hypoxia resulted in increased OD values at days 2 and 3. b, c CFSE assays showed that hypoxia resulted in increased cell proliferation at day 3. Student’s t tests were performed to determine statistical significance. All error bars represent SD (n = 3). **p < 0.01
