A method of visualizing and quantifying the 3-dimensional structure of mouse hepatic portal vein or intrahepatic bile duct is described. This resin cast technique can also be applied to other ductal or vascular systems and allows for in situ visualization or quantification of a system's intact communicating architecture.

Disruption of bile flow results in severe inflammatory cholestatic liver injury with a characteristic time-dependent sequence of morphological alterations. Here we present a protocol for the surgical ligation of the common bile duct in mice that allows to induce a strong fibrotic response after 21 to 28 days.

Human tumor xenografts in immunodeficient mice are valuable tools to study cancer biology. Specific protocols to generate subcutaneous and intrahepatic xenografts from human hepatocellular carcinoma cells or tumor fragments are described. Liver regeneration induced by partial hepatectomy in recipient mice is presented as a strategy to facilitate intrahepatic engraftment.
FAQs
Cholangiocytes, the cells lining the ductules and larger intrahepatic ducts, secrete water and bicarbonate into the passing bile. This modification changes the composition of bile after it leaves the canaliculi between hepatocytes. Because the ducts enlarge progressively along the pathway, their lining contributes to bile processing while also supporting its movement toward the extrahepatic biliary tree.
Bile moves through a sequence that begins in tiny canaliculi, continues through ductules, and reaches progressively larger ducts. This organized pathway means that abnormalities such as obstruction, strictures, stones, or tumors may interfere with bile passage at different points. Recognizing the ductal arrangement helps clinicians interpret changes in biliary anatomy and connect them with impaired bile flow.
The intrahepatic portion collects and channels bile within the liver before it reaches the extrahepatic biliary tree. This distinction helps clinicians describe where a biliary abnormality occurs. Imaging findings involving ducts inside the liver can therefore be considered separately from changes beyond the liver, supporting more precise assessment of biliary obstruction, narrowing, or injury.
Ultrasound and magnetic resonance cholangiopancreatography are identified as methods for evaluating intrahepatic ducts, along with other imaging approaches. These studies can reveal abnormalities in duct caliber and structure, including dilation, strictures, stones, or tumors. Their findings provide anatomical information that supports investigation of suspected cholestatic liver disease or biliary injury.
Dilation and strictures are important structural findings because they may signal abnormal bile passage through the biliary network. Stones and tumors are additional abnormalities that imaging may identify. Interpreting these findings in relation to the intrahepatic pathway helps clinicians investigate the source of impaired bile movement and evaluate whether biliary disease or injury is present.
Magnetic resonance cholangiopancreatography provides an imaging-based view of the biliary channels, allowing clinicians to examine the intrahepatic ducts for structural abnormalities. In the supplied medical context, it is used alongside ultrasound and other imaging to identify dilation, strictures, stones, or tumors. This information helps characterize biliary disease without relying only on the duct’s microscopic structure.
The anatomy of the intrahepatic ducts links bile production by hepatocytes with the channels that carry and modify bile before it leaves the liver. When this pathway is affected by obstruction, narrowing, stones, tumors, or injury, clinicians can use its structure and imaging appearance to guide diagnosis and treatment of cholestatic liver disease and biliary damage.
