Fig. 2From: Expression of proinflammatory cytokines and proinsulin by bone marrow-derived cells for fracture healing in long-term diabetic miceCallus at the femur fracture site. Hematoxylin-eosin (HE) images of callus formation without long-term hyperglycaemia (LT-HG) at 2 weeks (2 W) after fracture (a), 3 weeks (3 W) after the fracture (b), with LT-HG at 2 W after fracture (c), and at 3 W after fracture (d) (bar: 1 mm). The cartilage is stained purple and bone tissue is stained pink. The percentage of chondrocyte areas within the callus were measured using Image pro plus. (e) Data are shows as the mean ± SD. *: p < 0.05. LT-HG positive; n = 10, LT-HG negative; n = 10Back to article page
