Flux of major metabolites consumed and produced by human embryonic stem cells cultured at physiological and atmospheric oxygen concentrations.

<p>Note: All data measured by HPLC analysis, except for ammonia, which was measured using the Bioflex analyser. Values are mean ± standard error, n = 6. Significance between the values measured at 20% and 2% oxygen were determined using a student's t-test where ** indicates a p-value<0.05, deemed statistically significant and *indicates a p-value<0.08, deemed statistically significant.</p><p>Flux of major metabolites consumed and produced by human embryonic stem cells cultured at physiological and atmospheric oxygen concentrations.
