Evaluation of osteoblasts. Osteoblasts were counted in the fracture gap or an equivalent area in the Sham groups in TRAP-stained slices. (a) Two areas for counting were defined on the inner left and right cortical side within the medullary cave (black rectangles). (b) Violet, cubic cells arranged in lines with contact to bone are counted as osteoblasts (red rectangle). Scale bar 100 μm, magnification 300-fold.
