a Western blots of CYR61 expression within the callus tissue of controls and sildenafil-treated mice at 2, 5 and 10 weeks after surgery. b Expression of CYR61 (pixel intensity ×104) within the callus tissue of controls (white bars, n = 3) and sildenafil-treated mice (black bars, n = 3) at 2, 5 and 10 weeks after surgery. c Western blots of VEGF expression within the callus tissue of controls and sildenafil-treated mice at 2, 5 and 10 weeks after surgery. d Expression of VEGF (pixel intensity ×104) within the callus tissue of controls (white bars, n = 3) and sildenafil-treated mice (black bars, n = 3) at 2, 5 and 10 weeks after surgery. e Western blots of HO-1 expression within the callus tissue of controls and sildenafil-treated mice at 2, 5 and 10 weeks after surgery. f Expression of HO-1 (pixel intensity ×104) within the callus tissue of controls (white bars, n = 3) and sildenafil-treated mice (black bars, n = 3) at 2, 5 and 10 weeks after surgery. g Western blots of PCNA expression within the callus tissue of controls and sildenafil-treated mice at 2, 5 and 10 weeks after surgery. h Expression of PCNA (pixel intensity ×104) within the callus tissue of controls (white bars, n = 3) and sildenafil-treated mice (black bars, n = 3) at 2, 5 and 10 weeks after surgery.
