Figure 7

Microphotograph of decalcified sections, osteopontin (white arrows) and PCNA expression. Picture shows Z3 areas of femoral: (a) actuator and (b) static control, suggesting more extensive osteopontin labeling around actuator. Double Fast-Red and DAB immunohistochemistry staining for osteopontin and PCNA, respectively. Scale bar represents 100 μm.
