Biochemical properties of constructs after 4 weeks of culture. GAG (A) and collagen content (B) of each construct was assayed using the dimethylmethylene blue and hydroxyproline assays, respectively. All values are normalized by construct dry weight (dw). There were no significant differences in GAG between groups. Collagen content was significantly lower in the 100% MZ constructs compared to all other groups, with the exception of 100% SZ constructs. Values are presented as mean±SD.
