Increased expression of chondroitin sulphate proteoglycans in rat hepatocellular carcinoma tissues

Figure 6 Immunochemical staining for versican in rat liver tissues. Versican positive staining was dark red. A-F: Most of hepatocytes were negatively stained in control group (A and D), whereas more hepatoma cells in hepatocellular carcinoma (HCC) nodules were positively stained (B and E); however, the strongest versican positive staining was observed in the fibrosis septa between hepatoma nodules (C and F). Short red arrows: The cells are magnified in the small boxes; G: Comparison of the positive rate for versican staining in liver tissues between the control and HCC model groups. ^aP < 0.05.
