(g) Oxygen consumption rate (OCR) was measured in HE and EHT cells (n=3 biological replicates with 2-3 technical replicates each) and oxidative phosphorylation was assessed by extracellular flux analysis. Bar graphs show relative levels ± SEM of the indicated processes (from 3 independent experiments; unpaired t-tests). Data information: ns, not significant, *p<0.05, **p<0.01, ***p<0.001, ****p<0.0001
