Fig. 1 Safranin-O staining of equine (A) and human (B) articular cartilage from the central sites of the femoral condyles. Average thickness of equine (n = 15) and human (n = 23) cartilage from the central sites of the femoral condyles (C). A significant difference was observed between the lateral and medial condyle of equine samples (P = 0.003). Error bars indicate 95% confidence intervals.
