Maximum Force in the Three-point Bending Biomechanical Test.

<p>In the <i>Igf-1r</i> and <i>Pth1r</i> siRNA transfection groups, the mechanical properties of the left tibias, which received <i>Igf-1r</i> or <i>Pth1r</i> siRNA injections, were dramatically diminished compared to the right tibias (I-1-1 and P-1-1, one injection for one week; I-1-2 and P-1-2, one injection for two weeks; I-2-2 and P-2-2, two injections over two weeks). *p<0.05 and **p<0.01.
