Figure 4. Measurements of glycolysis activities in hADSCs. (A) ECAR in hADSCs at each phase of the glycolysis pathway. (B) Statistical analysis of ECAR at each phase. (C) Relationship between ECAR and OCR in the glycolysis pathway of hADSCs. GM: Metformin. (D) Western blotting of GAPDH protein expression. Data are presented as the mean ± SD of three independent experiments. Statistical significance was determined by the unpaired t-test. *p < 0.05, **p < 0.01, ***p < 0.001 compared with the Ctrl.
