N normal phenotype
liver/biliary system
• diffuse bile duct proliferation is observed around small and large bile ducts by 4 weeks of age
• by 12 weeks of age, 50% of mice have bile duct proliferation with these ducts appearring small and slit-like
• at 8 weeks of age, some mice have dilated bile tracts and expanded portal tracts
• cytokeratin staining also shows irregular, dilated ducts surrounding the periphery of many portal tracts
• bile stasis is identified within the lumina of several proliferating ducts

endocrine/exocrine glands
