Wnt ligand and receptor patterning in the liver

Area of Science:

• Hepatology
• Molecular Biology
• Cell Biology

Background:

• Liver zonation establishes metabolic zonation, a form of tissue polarity crucial for liver function.
• Wnt/β-catenin signaling plays a critical role in maintaining this spatial organization.
• Dysregulation of liver zonation is implicated in various liver diseases.

Purpose of the Study:

• To review the latest technological advancements in studying liver zonation.
