Culture and immortalization of pancreatic ductal epithelial cells.
Abstract
Some populations of the epithelial cells from the duct and ductular network of the mammalian pancreas have been isolated and maintained in vitro for up to 3 mo. These cells express many of the surface factors that are unique to them in vivo. They also retain significant drug- and carcinogen-metabolizing capacity in vitro. In this chapter we review the progression of the methods for the isolation, culture and maintenance in vitro for these cells from the earliest when only duct/ductular fragments were obtainable to the current ones which provide epithelial cells. The critical steps in the isolation process are identified and strategies are provided to facilitate these steps. These include the selection of tissue digestive enzymes, the importance of extensive mincing before culture and the importance of roles of some co-factors used in the culture medium.
