Figure 6From: Over-expression of glutamine synthase in focal nodular hyperplasia (part 1): Early stages in the formation support the hypothesis of a focal hyper-arterialisation with venous (portal and hepatic) and biliary damageJunction between non-nodular tissue (lower part) and nodule (upper part). The upper micrograph (A) shows CK7 staining, and the lower micrograph (B) displays CK19 staining. There is no (CK19) or less (CK7) biliary cells in the nodular part compared to the non-nodular part.Back to article page
