Figure 3. Histological sections of the specimen from the experimental group at 8 wks stained with hematoxylin and eosin. (A) Low magnification. New bone formation (b) is observed around remaining fat tissue (f). Blood vessels (v) retain normal structure. (B) High magnification. Induced bone contains fine blood vessels. In this case, barium sulfate was injected into the femoral artery before the animal’s death, and the contrast compound is found within those vessels (arrow).
