Nerve growth factor involvement in liver cirrhosis and hepatocellular carcinoma

Figure 1 NGF distribution in tissues from healthy donors. B, C, D, F, G: Confocal microscopy images of immuno-stained sections; in negative hepatocytes, endothelial cells, biliary epithelial cells and Kupffer cells the immunoreaction is the same as the background obtained in control performed by substitution of primary antisera with non-immune rabbit serum; positive immunoreaction (red hue) is only observed on lymphocytes in blood vessels. Green hue represents the auto-fluorescence used to visualize liver tissue morphology; A, E, H: Images of H&E stained sections close to that used for immunohistochemistry. Differently coloured arrows indicate the different cell types (see legend). bec: biliary epithelial cells; hep: hepatocytes.
