Oxygen flux in intact wild-type mesenchymal stem cells (WT-MSC) and MRL/MpJ mesenchymal stem cells (MRL-MSC). (A) RDMEM, LEAK and ETS oxygen consumption in intact WT-MSC and MRL-MSC. RDMEM represents routine respiration, LEAK represents oxygen consumption independent of ADP phosphorylation and ETS indicates maximal electron transport capacity. (B) Flux control ratios (FCR). Ratios of oxygen flux in differing respiratory control states, normalized to a defined reference respiratory state. n = 6, data are mean ± S.E.M. *p < 0.05 vs. WT-MSC.
