A Representative Western blots of VEGF, COX-2, PI3K and β-actin expression within the callus tissue of controls and PTH-treated mice at 2 weeks after surgery. B–D Expression of VEGF (pixel intensity × 104) (B), COX-2 (pixel intensity × 104) (C) and PI3K (pixel intensity × 104) (D) within the callus tissue of controls (white bars, n = 3) and PTH-treated mice (black bars, n = 3) at 2 weeks after surgery, as assessed by Western blot analysis.
