Figure 1 Schematic presentation of woodchuck hepatitis virus-induced liver disease progression and detection of tumors within woodchuck liver. A: Neonatal woodchucks are experimentally infected with woodchuck hepatitis virus (WHV) to model vertical hepatitis B virus transmission in humans; B: WHV infection progresses to chronic hepatitis B in adult woodchucks after approximately 1 year; C: Chronic WHV carrier woodchucks develop liver tumors during the next 1-1½ years. A focus of altered hepatocytes (FAH) in liver (top) and an undifferentiated liver tumor (bottom) are shown; D: Localization of liver tumors by ultrasonography (top) and computed tomography (middle). The liver of a woodchuck with two larger hepatocellular neoplasms (HCC) is shown (bottom).
