Cholangiocytes are epithelial cells that line the intra- and extrahepatic ducts of the biliary tree. The main physiologic function of cholangiocytes is modification of hepatocyte-derived bile, an intricate process regulated by hormones, peptides, nucleotides, neurotransmitters, and other molecules through intracellular signaling pathways and cascades. The mechanisms and regulation of bile modification are reviewed herein.

Obtaining stable hepatic cells in culture poses a significant challenge for liver studies. Bearing this in mind, an optimized method is depicted utilizing human induced pluripotent stem cells (hiPSCs) to generate 3D cultures of human hepatic organoids (HHOs). The utilization of HHOs offers a valuable approach to understanding liver development, unraveling liver diseases, conducting high-throughput studies for drug development, and exploring the potential for liver transplantation.

Combined hepatocellular cholangiocarcinoma (cHCC-CCA) is a unique subtype of primary liver cancer displaying both hepatocytic and cholangiocytic differentiation. The development of effective treatments for cHCC-CCA remains challenging because of its high heterogeneity and lack of a suitable model system. Using a three-dimensional culture system, we successfully established two novel cHCC-CCA organoid lines from patients undergoing surgical resection for primary liver cancer.

Biliary obstruction and cholangiocyte hyperproliferation are important features of cholangiopathies affecting the large extrahepatic bile duct (EHBD). The mechanisms underlying obstruction-induced cholangiocyte proliferation in the EHBD remain poorly understood. Developmental pathways, including WNT signaling, are implicated in regulating injury responses in many tissues, including the liver.

Hepatoblasts are the bipotential progenitors of liver cells that differentiate into either hepatocytes or cholangiocytes. In their study, Marino Zerial and colleagues reveal how hepatoblast polarisation and lumen morphogenesis are linked to hepatocyte cell fate determination. To know more about their work, we spoke to the first authors, Maarten Bebelman and Lenka Belicova, and the corresponding author, Marino Zerial, Director and Scientific Member at the Max Planck Institute of Molecular Cell Biology and Genetics.

The experiment mainly focused on the liver of the hybrid grouper (Epinephelus fuscoguttatus ♀ × E. lanceolatus ♂) with low methionine levels by single-cell RNA-seq under high-lipid diets. Both weight gain rate (WGR) and specific growth rate (SGR) in the MR group were obviously lower than the C group, and the intraperitoneal fat (IPF) in the MR group was obviously enhanced than HL and C groups, which led to more visible growth inhibition and lipid deposition.
