HepPar-1 and CD31 immunohistochemistry. A. HepPar-1 in the liver tumor tissue. The neoplastic cells showed diffusely HepPar-1 positive. A tumor tissue of 121–1, immunohistochemical staining for HepPar-1, 200×. B. HepPar-1 in the normal liver tissue. Normal hepatocytes generally showed HepPar-1 positive. A liver tissue of 131–3, immunohistochemical staining for HepPar-1, 200×. C. CD31 in the liver tumor tissue. CD31 was densely stained along the membrane of the sinusoidal endothelial cells. A tumor tissue of 121–1, immunohistochemical staining for CD31, 100×. D. CD31 in the normal liver tissue. Liver sinusoidal endothelial cells in the non-tumor tissue were CD31 negative, only blood vessels in portal tracts were positive. A liver tissue of 137–2, immunohistochemical staining for CD31, 100×.
