Overall sulfated GAG and collagen production per scaffold are upregulated in hydrogels with CS-SILY molecules. GAG production of the cell-hydrogel constructs (n = 4) with or with added CS or CS-SILY molecules after a (A) 21-day or (B) 28-day culture period. Total collagen of the cell-hydrogel constructs (n =3) with or with added CS or CS-SILY molecules after a (C) 21-day or (D) 28-day culture period. Values are expressed as mean ± standard deviation. ANOVA and Tukey’s post hoc tests were performed. Data that share the same letter do not have statistically significant differences (p > 0.05) whereas data that do not share the same letter have statistically significantly differences (p < 0.05).
