Figure 8From: 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) was trichrome stained, and the lower micrograph (B) was α-SMA stained. It confirms the proliferation of arteries in the nodules and the presence of fibrotic portal tracts at the periphery of the nodule.Back to article page
