The effect of hypoxic preconditioning on MSC to LincRNA-p21, HIF-1α, and CXCR4/7. RT-PCR, WB analysis, and ELISA kits were applied to test hypoxic preconditioning (1% O2) induced MSCs signaling change at 24 h. a The effect of hypoxic preconditioning on MSC to LincRNA-p21 relative quantitative expression. b The effect of hypoxic preconditioning on MSC to HIF-1α mRNA relative quantitative expression. c The effect of hypoxic preconditioning on MSC to HIF-1α and CXCR4/7 protein expression using WB analysis. d HIF-1α concentration in hypoxic preconditioning induced MSC supernatant. Results are mean ± SD (n = 3). *p < 0.05 vs. group normoxia or hypoxia time 0 h
