Intensity-Dependent Effect of Treadmill Running on Knee Articular Cartilage in a Rat Model
Figure 5
Immunostaining of collagen II of femoral articular cartilage in SED (a), LIR (b), MIR (c), and HIR (d) groups. In comparison to group SED, increased staining of collagen II was found in LIR and MIR groups, whereas less staining was detected in HIR group. Collagen II content in each group was shown in (e). In comparison with group SED, higher collagen content was found in groups LIR and MIR, without significant difference. However, the collagen content in group HIR was significantly lower than that in group SED. # compared to HIR group.
