Figure 5From: Pulsed electromagnetic fields stimulation prevents steroid-induced osteonecrosis in rats Protein expression of TGF-β1 in proximal femur. (A) The protein expression levels of TGF-β1 were evaluated by western blot analysis. (B) Data are expressed as expression ratios normalized to β-actin protein expression and presented as the mean ± SD. # P < 0.05 versus PS group, *P < 0.05 versus MPSL group.Back to article page
