Members of the Cyr61/CTGF/NOV Protein Family: Emerging Players in Hepatic Progenitor Cell Activation and Intrahepatic Cholangiocarcinoma

Figure 3

Immunofluorescent staining detects abundant CCN2/CTGF protein in fibrotic human CCA tumors. Trichrome or CCN2/CTGF staining was carried out on human intrahepatic CCA tissue arrays. Representative images for human CCA tumors (a) or non-CCA control tumors (pheochromocytoma) from adrenal glands (b) were shown. Inserts are macroscopic views of the stained tissues. Scale bar: 100 μm. Arrowheads indicate the same location in each set of images in Figure 3.
