Figure 2

lrp5^-/- adult fish display low bone mineral density. (A) Whole-mount alizarin red staining at 1.5 mpf display the distribution of mineralized matrix through the head bones. In the skull of lrp5^-/- distribution of mineralized matrix throughout whole head bones differs from lrp5^+/+ Scale bar=1mm. (B) coronal view of the cranial vault. The alizarin red signal is distributed ubiquitously in lrp5^+/+ lower jaw (C) and opercle (D), meanwhile in lrp5^-/- fish the lower jaw demonstrated discontinues alizarin red signal. Scale bar=500µm. (E) Representative photos of lrp5^+/+ and lrp5^-/- siblings at 4mpf; lrp5^-/- present with deformed head and body curvatures. Scale bar=1cm. (F) 3D reconstruction of X-ray images of lrp5^+/+ and lrp5^-/^- skeleton at 3 and 6mpf. Scale bar= 1cm (G, H) Total BMD is decreased in adult lrp5^-/- fish. (I, J) the skull BMD of lrp5^-/- mutant fish is significantly lower both at 3 and 6mpf. Results in G-J are expressed as mean SD (3mpf n =13-15 fish, 6mpf n =12-13 fish, t-test).
