Portal vein ligation accelerates tumor growth in ligated, but not contralateral lobes

Figure 3 Effects of portal vein ligation on liver necrosis and apoptosis. A: Liver injury was measured by serum levels of alanine aminotransferase (ALT). Data are mean ± SE with n = 4-6 per group; B: Representative pictures of HE staining (upper) and TUNEL staining (bottom). TUNEL staining was performed to determine the amount of hepatocyte apoptosis. Original magnification was 200 ×. PVL: Portal vein ligation.
