Randomized trial identifies candidate stem cells and cell lineages in ductular reactions within cirrhotic liver, suggesting regenerative potential.

The aim is to identify lineages of hepatocytes and bile ductular cells, as well as potential stem cells in ductular reactions observed in cirrhosis.
Conducted single, double, and triple staining with NCAM, CK19, and HepPar1 to study cell lineages.
Performed spatial analysis of cells based on staining positivity for specific markers.
Developed a working cell lineage model for ductular reactions.
Identified a bipolar structure in ductular reactions composed of hepatocytic and biliary poles.
Detected bipotent liver stem/progenitor cells through NCAM-positive staining in ductular reactions.
Characterized CK19+/NCAM+ cells as transitional in the biliary lineage, with rare cells negative for all three markers being transitional in the hepatocytic lineage.

Zhou et al. (2007) studied this question.
