Fig. 3From: Serum β-catenin changes vary among different stages of osteonecrosis of the femoral head: an exploratory biomarker studyWestern blot analysis of cartilage samples for the β-catenin. A Level of β-catenin is increased with the ARCO stage. 3 samples in control, 3 samples in stage II, 3 samples in stage III, and 4 samples in stage IV were done. B The histogram represents western blotting analysis. Values are the means ± SEM. aP < 0.001 vs the control group; bP < 0.001 vs the stage II group; cP < 0.001 vs the stage III groupBack to article page
