Gene expression in chondrogenic cultures of infrapatellar fat pad (IPFP) cells. Relative gene expression for proteoglycans (a), collagens (b), and SOX genes (c) in monolayer with and without FGF-2-supplemented medium to determine basal levels and following subsequent chondrogenesis for 14 days is shown. Data are mean ± standard error of the mean (n = 6). *P < 0.05, **P < 0.001 (analysis of variance with Bonferroni correction).
