Area of Science:

  • Hepatology and stem cell biology
  • Gastroenterology and biliary system research

Background:

  • Intrahepatic biliary diseases lack effective human models for studying disease progression.
  • Current models fail to replicate the complex biliary microenvironment and its impact on cholangiocytes.

Purpose of the Study:

  • To develop a physiologically relevant, perfusable 3D bile duct model using human pluripotent stem cell (hPSC)-derived cholangiocytes.
  • To investigate the role of microenvironmental signals in cholangiocyte behavior and disease pathogenesis.

Main Methods:

  • Generation of a fully epithelialized, perfusable 3D bile duct model from hPSC-derived cholangiocytes.
  • Characterization of the model for primary ciliation, polarity, and CFTR-mediated conductance.
  • Interrogation of bile acid toxicity and cytokine-driven injury using the 3D model.

Main Results:

  • The 3D model exhibited robust primary ciliation, apical-basal polarity, and CFTR-mediated chloride conductance.
  • Physiologically relevant fluid flow and biliary stroma cells were crucial for maintaining cholangiocyte barrier integrity and ciliation.
  • The model provided insights into intrahepatic cholangiocyte stress responses to bile acid and cytokine injury.

Conclusions:

  • The developed 3D hPSC-derived cholangiocyte model offers a high-fidelity platform for studying intrahepatic biliary diseases.
  • This model is essential for decoding pathogenic drivers and accelerating therapeutic development for cholangiopathies.
