Figure 7From: 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 damageAnother area of the previously described upper section. The figure shows the upper section as previously described (Fig. 4-5), but in another area. The upper micrograph (A) shows GS staining, and the lower micrograph (B) has CK7 staining. It confirms the extension of GS staining and the decrease number of biliary cells in the nodule.Back to article page
