[Retracted] Effects of Early Weight-Bearing Treadmill Training Combined with Pre-Emptive Analgesia on Femoral Fracture Recovery

Figure 6

IHC staining results of BMP-2. (a) Representative images of bone tissue around the fracture site from four groups at 7 d after surgery by IHC staining of BMP-2 (scale bars, 50 μm). White arrows indicate positive cells with brown stain. (b) Representative images of bone tissue around the fracture site from four groups at 14 d after surgery by IHC staining of BMP-2 (scale bars, 50 μm). White arrows indicate positive cells with brown stain. (c) Representative images of bone tissue around the fracture site from four groups at 21 d after surgery by HE staining of BMP-2 (scale bars, 50 μm). White arrows indicate positive cells with brown stain. (d) Representative images of bone tissue around the fracture site from four groups at 28 d after surgery by HE staining of BMP-2 (scale bars, 50 μm). White arrows indicate positive cells with brown stain. (e) Representative images of bone tissue around the fracture site from four groups at 35 d after surgery by HE staining of BMP-2 (scale bars, 50 μm). White arrows indicate positive cells with brown stain. (f) Immunohistochemical score of BMP-2 for each group at every time points (n = 3). For quantification of each sample, 3 optic fields were chosen randomly. vs. group B; ^# vs. group C.
