Fig. 4From: The effect of hypoxia on chondrogenesis of equine synovial membrane-derived and bone marrow-derived mesenchymal stem cellsRelative expression (mean ± SEM) of chondrogenic-related genes including SOX9, ACAN, COL2b and COL10A1 for BM-MSC and SM-MSC pellets cultured in normoxic (21% O2) and hypoxic (5% O2) conditions for 28 days. Expression is relative to normoxic BM-MSC pellets. 18S was used as a reference gene in all analyses. * p < 0.05Back to article page
