MSC growth and gene expression in normoxic (18.4% O2) and physioxic (3% O2) conditions. A MSC cell density and viability in normoxic and physioxic conditions after 96 h in culture. B Fold change in gene expression levels in MSCs cultured in physioxic as compared to normoxic environments. Expression levels are normalized to 18S. N = 5, *P < 0.05, bars represent mean and SD. C 10× phase contrast microscopy images of MSCs after culture in normoxic and physioxic conditions for 24 h (total 96 h in culture). Scale bar = 100 μm
