Gene expression in chondrogenic cultures of infrapatellar fat pad cells. Relative gene expression for hypoxia-inducible transcription factors (HIF) and SOX genes (a), collagens (b) and proteoglycans (c) in monolayer culture and after chondrogenic differentiation for 14 days under normoxic and hypoxic conditions. Results are means ± SEM (n = 3). **p < 0.001; *p < 0.05 (analysis of variance with Bonferroni's correction).
