Normalized GAG content measured at 0 and 7 days, expressed as GAG/DNA. The IGF group had the highest GAG/DNA content at day 7 on the non-coated surface. Values are reported as mean ± standard deviation, n = 4. (@) represents statistically significant difference from the control group at that time point, (*) represents statistically significant difference from t = 0 h, (**) represents statistically significant difference among different media groups, (&) represents statistically significant between coated and non = coated groups (p < 0.05).
