Lymphatic vessels increase in fibrotic regions of cirrhotic livers independent of disease etiology. Liver explants were obtained from cirrhotic patients who received liver transplantation. Non-Alcoholic Steatohepatitis (NASH) (n = 8), Alcoholic liver disease (ALD) (n = 12), chronic Hepatitis C viral infection (HCV) (n = 5), Autoimmune hepatitis (AIH) (n = 1), Wilson's disease (n = 1), Primary sclerosing cholangitis (PSC) (n = 1) and four non-diseased livers. Representative images from non-diseased (A) or ALD (B) explants are shown. Five micrometer sections were stained with anti-podoplanin (lymphatic vessels D2/40-red), anti-CD3 (T cells-white), anti-CD68 (macrophages-green), and dapi (nuclei-blue) and imaged using the Perkin Elmer Vectra 3.0 imaging system and linear unmixed with inFORM software. (C) Lymphatic vessels density was determined using inFORM software and normalized to area in each disease listed and designated by color of dot. Statistical analysis was performed using a student's t-test. **P < 0.01.
