Fig. 2From: Alcohol exposure decreases osteopontin expression during fracture healing and osteopontin-mediated mesenchymal stem cell migration in vitroFracture callus histology (H&E staining 10×). Histological structure of the fracture site is shown at 3 days post-fracture in saline control (a) and alcohol exposed (b). The fracture site of saline control mice shows evidence of granulation tissue accumulation (boxed area) and the presence of early cartilaginous callus formation (arrows). In contrast, the injury site of alcohol-exposed mice shows no evidence of granulation tissue accumulation or ormation or cartilage tissue. n = 2 per groupBack to article page
