3-Dimensional Resin Casting and Imaging of Mouse Portal Vein or Intrahepatic Bile Duct System

Overview

This article describes a method for visualizing and quantifying the 3-dimensional structure of mouse hepatic portal vein or intrahepatic bile duct using a resin cast technique. This method allows for in situ visualization of the intact communicating architecture of ductal or vascular systems.

Key Study Components

Area of Science

• Neuroscience
• Vascular Biology
• Histology

Background

• Understanding the structure of vascular systems is crucial for various biological studies.
