Ductular formation of hepatocytes in this 2-week old AL-TAg x AL-myc mouse has a predominantly centrilobular localization.
An altered hepatocyte focus is arising in an area of ductular formation in this 2-week old AL-TAg x AL-myc mouse.
Focal areas of bile duct proliferation also arise within areas of ductular formation in 2-week old AL-TAg x AL-myc mice.
Increased severity of focal bile duct proliferation associated with an area of ductular formation in a 3-week old AL-TAg x AL-myc mouse.
Areas of ductular formation and bile duct proliferation can be extensive in the livers of 3-week old AL-TAg x AL-myc mice.
By 4-weeks of age much of the liver is replaced by areas of ductular formation, cholangial neoplasms, and hepatocellular neoplasms in AL-TAg x AL-myc mice.
