Quantification of COL 2 and MMP 13 secretion of cell-seeded scaffolds cultured under chondrogenic conditions.
(a,b) Concentration of COL 2 and MMP 13 in culture media of cell-scaffold constructs were determined by ELISA (n = 4, *p < 0.001). Data were normalized to the DNA content of cell-scaffold constructs; (c,d) Western blotting analysis of COL 2 produced by cell-seeded scaffolds undergoing chondrogenesis culture. (Results are expressed as mean ± 95% CI, n = 3, *P < 0.001).
