Histological evaluation of the number and activity of osteoblasts.

(a1–a4) H&E staining revealed osteoblasts (black arrows) along the edge of the bone trabeculae (b1–b4) Active osteoblasts were stained for ALP (white arrows). Quantitative analyses showing the number of osteoblasts per unit of tissue area, N.Ob/T.Ar (/mm2) (c) in bone callus; the two black horizontal lines in each graph represent the upper and lower 95% confidence limits of the number and activity of osteoblasts in the CI.
