Features of sacroiliac joint of Hyp and WT mice. (A) Micro-CT analysis showed bone erosion of the sacroiliac joint in Hyp mice which appears at early stages and progressed up to M12 (representative micro-CT sections from Hyp#2 mouse) (scale bars, 500 μm). (B) Masson’s trichrome staining displayed that sacroiliac bone of Hyp mice presented a large amount of collagen matrix compared to WT mice. Von Kossa staining showed a weak mineralization (in dark) of the Hyp collagen matrix revealing an enlarged osteoid characteristic of features of osteomalacia bone. Safranin O staining revealed high wear of cartilage at M3 in Hyp mice (scale bars, 200 μm).
