3. Fig. 2
Histological and biochemical analysis to evaluate the chondroprotective effect of HA/PEG/KGN hydrogels after IA injection into OA rats. Representative image of knee joints: Safranin O staining and immunohistochemistry for COL2 and aggrecan at 8 weeks after the first IA injection (A). Naive rat knee joint is also shown as a normal control. The graph shows the OARSI (B) and Mankin (C) scores in the medial tibial plateau. Data are presented as mean ± SD (N = 10). [*p< 0.05, **p< 0.001].
