Zonal response and cartilage formation by chondrocytes in dual-gradient hydrogels. (A−F) Quantitative gene expressions of cartilage markers at day 7 normalized to day 1. (G−I) Cell proliferation and accumulated matrix deposition by chondrocytes in dual-gradient hydrogels at day 21. Statistical analyses were performed using one-way analysis of variance (ANOVA), with Benjamin-Hotchberg correction for multiple posthoc comparisons of all adjacent zones. n = 3/group; *P < 0.05.
