Gene expressions of Achilles tendon (n = 12) 14 days after collagenase injection. Gene expression ratio of (A) collagen I, (B) collagen III, (C) collagen III/collagen I ratio, (D) Pparg (adipogenic), (E) Sox9 (chondrogenic) and (F) Runx2 (osteogenic). The control group was injected with saline instead of collagenase. Data are expressed as mean ± SD (*p < 0.05) fold-changes of expression level relative to the control. HA, HA hydrogel; HA/EGCG, EGCG-loaded hydrogel.
