Immunohistochemical staining of Collagen type I, Cathepsin K, and CTX-I in: early and advanced lesions. A, B and C: staining of Collagen type I, Cathepsin K and CTX-I, respectively in an early lesion. D, E and F: staining of Collagen type I, Cathepsin K and CTX-I, respectively in an advanced lesion. A1, B1, C1, D1, E1 and F1 are 2× magnified, whereas A2, B2, C2, D2, E2 and F2 are 10 × magnified. Brown colouring suggest positive staining with the particular antibody, whereas blue staining suggest Hematoxyllin staining of the cell nuclei.
