This section presents diagrams for pathways present in exocrine pancreatic cells. Although components known to be present in cells in general may be included to make a complete pathway, the emphasis is on components that have been studied in pancreatic acinar, ductal and stellate cells as well as the pathway initiators and effectors. Each pathway may have associated short Reviews, Molecules and Methods. One aim of this section is to help generate a molecular parts list and interaction diagram that describe pancreatic cells. Community members who establish the presence of specific molecules or isoforms are encouraged to contribute to the Pancreapedia.
