Collagen level in engineered cartilage constructs, estimated based on hydroxyproline content, as a function of culture time. In TGF-β1 and TGF-β1/IGF-I treated groups, hydroxyproline accumulation showed significant increase over time points (p<0.001). Values are mean ± SD (n=6). Data were analyzed using two-way ANOVA.
