Ductal cells of the pancreas form the epithelial lining of the branched tubes that deliver enzymes produced by pancreatic acinar cells into the duodenum. In addition, these cells secrete bicarbonate that neutralizes stomach acidity. During development, epithelium of endodermal origin evaginates from the future duodenum area and invades the mesenchyme to form a complex branched network. All endocrine, acinar and ductal cells arise from common precursors in this epithelial structure. Adult ductal cells share some similarities with embryonic primitive ducts and may retain the ability to generate endocrine cells in the adult. Based on challenged pancreas regeneration experiments, the adult ductal cells have been proposed to be pancreatic stem cells but their role in normal endocrine cell turnover has recently been challenged. Manipulating their ability to give rise to endocrine cells may open new avenues in the treatment of diabetes and therefore they have recently been under scrutiny. In addition, in the main form of pancreatic cancer, pancreas adenocarcinoma, tumor cells share similarities with ductal cells. The secrets of an appropriate therapy for this deadly cancer may thus reside in the biology of ductal cells.
