Low contrast medium and radiation dose for hepatic computed tomography perfusion of rabbit VX2 tumor

Figure 5 Histological and immunohistochemical micrographs of hepatic VX2 tumor. A: Tumor tissue stained with hematoxylin and eosin (magnification × 400) demonstrates that the normal hepatic sinusoidal capillary disappeared and was replaced by a large amount of tumor cells; B: CD31 staining of tumor tissue shows the formation of new microvessels with incomplete layer of endothelial wall (arrows, magnification × 400); C: Vascular endothelial growth factor staining of tumor tissue depicts positive expression in the cytoplasm of tumor cell (arrows, magnification × 400).
