Representative Photomicrographs of Undecalcified Sections Stained with Goldner’s Trichrome.

<p>In the left tibias treated with <i>Igf-1r</i> or <i>Pth1r</i> siRNA, osteoid accounted for a very large proportion, which was obviously greater than that in the right tibias, in which the majority was mature trabecular bone. Mature trabecular bone and osteoid are stained green and red, respectively. Scale bar = 50 μm.
