Immunostaining of Ddr2 in TM joint articular cartilages of Col9a1-/-, cho/+ and wild-type mice at the ages of 3 and 6 months. The increase in immunostaining intensity of Ddr2 (brown color staining) was seen in both mutant mice at the age of 6 months. Individual positive staining cells were seen in the enlarged inserts (2× enlargement). There was no detectable immunostaining of Ddr2 in the TM articular cartilage of the mutant and wild-type mice at the age of 3 months. Bar = 50 μm.
