Figure 7From: FGF9 can induce endochondral ossification in cranial mesenchymeBrdU incorporation and cell proliferation. BrdU incorporation (brown stain) was detected by immunohistochemistry (A-D). A significant increase in BrdU positive (brown stained nuclei) cells was detected in the parietal region of the FGF9 transgenic mice at E11 and at E13 (E). Scale bar: 100 μm in A-D.Back to article page
