Figure 1From: The effect of core decompression on local expression of BMP-2, PPAR-γ and bone regeneration in the steroid-induced femoral head osteonecrosis BMP-2 protein expression in the femoral head tissue by western blot analysis. (A) Western blot showed the expression levels of BMP-2 protein in the femoral head bone tissues in the normal control animals and experimental animals with or without decompression at each 2, 4 and 8 week time point; (B) Western blot results of BMP-2 expression in the femoral head was indicated by the ratio of band intensity of BMP-2 with GAPDH.Back to article page
