The levels of glycolysis were decreased in MSCs from old rats. A–D Relative glucose uptake (A), lactate secretion (B), relative ATP levels (C) and ECAR levels (D) were measured in MSCs from young and old rats. All data were presented as mean ± SEM (error bars), n = 3, ***P < 0.001, **P < 0.01, *P < 0.05, N.S. indicated no statistical value
