Figure 9From: 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 damageGlutamine synthase immunostaining. A: Normal expression of GS around the central vein (non-nodular tissue). B: Extended staining around hepatic veins in the nodule.Back to article page
