Figure 1. Tissue expression of COL11A2 in patients and controls. (A) DDH patients were found to have significantly lower expression of the COL11A2 in the articular cartilage and ligament as compared with the controls (2.43 ± 1.65 vs 4.05 ± 1.89, p = 0.002 for articular cartilage; 2.46 ±1.68 vs. 3.85 ± 2.73, p = 0.007 for joint ligament). (B) Immunofluorescent assay of COL11A2 (green) expression and nucleus (blue) in the cartilage and ligament tissues in different groups of patients observed under confocal microscopy.
