From: 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 damage

Typical GS staining in the nodule. A – Higher magnification. B – Lower magnification. The nodule partly surrounds arterial vessels – these were better seen using α-SMA staining. The blue arrow indicates an artery, whereas the black arrow indicates a small hepatic vein (insert) with a thick wall and a narrow almost absent lumen.
