From: Expression of Connective Tissue Growth Factor in the Human Liver with Idiopathic Portal Hypertension
Histological examination of liver with IPH. (A) An enlarged portal tract containing proliferating bile ducts. Hematoxylin and eosin stain, ×100. (B) Collagen fibers are seen in the fibrous portal tract. Azan stain, ×40. (C-H) In situ hybridization shows positive signals for connective tissue growth factor (CTGF) mRNA in the epithelial cells of bile ducts (arrow), endothelial cells of portal tracts, and myofibroblasts (arrowhead) (C, ×100 and D-H, ×400). P, portal tract; B, bile duct; H, hepatocyte; S, sinusoid; E, endothelial cell; *, lumen.
