摘要

Hepatocellular carcinoma (HCC) is becoming one of the most common malignant tumors worldwide and is characterized by a high vascularity. VEGF is a endothelial cell—specific vasculogenic and angiogenic growth factor, but its expression and role in HCC have not been extensively explored. The aim of this study was to investigate the dynamic expression and alteration of VEGF during HCC development. Rat hepatoma models were induced with 2 - FAA on male SD rats. Morphological changes were observed by pathological examinations (HE staining). The expression of VEGF in rat liver tissues was semiquantitatively analyzed by immunohistochemistry. The VEGF levels in rat liver tissues and sera were detected by ELISA and Western blotting. Histological examination confirmed the rat hepatocytes from granule-like degeneration to atypical hyperplasia to HCC, and progressing increasing of hepatic VEGF levels during HCC development. The immunohistochemistry evidences indicated the positive expression and hepatocytes distribution of VEGF in rat hepatoma . The levels of hepatic or serum VEGF in degeneration, pre-cancerous and HCC groups were significantly higher than those in normal control group (P
