Inmunohistochemistry of heparanases. (A-D) Immunohistochemistry of HPSE. (A-D). Series of images showing the heterogeneous patterns of expression of HPSE in IDCs from negative staining (A), weak staining (B), moderate staining (C) and strong staining (D). Weak staining of breast normal tissue is indicated by an arrow (D); magnification A-C 400X, D 100X. (E,F) Immunohistochemistry of HPSE2. (E) Image of at least three terminal ductal lobular unit displaying immunostaining, mainly in the myoepithelial cells of ducts and acini. A slight reactivity in acinar and ductal cells can also be detected. (F) Tumor tissue forming ducts of different sizes and irregular light: The immunoreactivity for the antibody against HPSE2 is very low, magnification 200X.
