Pancreatic Acinar Tissue in Liver Explants

Abstract

Our results collectively indicate that pancreatic acini-like tissue in liver represent aggregates of pancreatic acinar cells admixed with small intra-acinar terminal ductules. Given the close spatial relationship with reactive bile ductules and the apparent transition in immunophenotype from bile ductules to pancreatic acinar tissue, the latter is likely of metaplastic origin derived from a hepatic progenitor lineage.
