Cell proliferation analysis of chondrocytes cultured in gelatin scaffolds. Cell proliferation was examined on days 1, 3, 7, 10, 14, 17 and 21 of cultivation. This data represents three separate experiments (n = 3). *, # p-values are < 0.05; **, ## p-values are < 0.01; * is a significant amount compared to the PBS control; # is a significant amount compared to the soluble control.
