Figure 6.

Images of alkaline phosphatase stained calvarial bone defect sections. (A) Fgf2−/− mice and (B) Fgf2+/+ mice. The ALP stain is pink and nuclei are stained with blue DAPI. White arrows in the images indicate the edges of the original bone defect. The images in the second rows of both (A) and (B) are higher magnification images of the white boxed areas in the top row. Scale bar = 200 μm. Quantified data for ALP expression in (C) Fgf2−/− mice and (D) Fgf2+/+.
