A conference entitled "The Pancreatic Duct Cell: Physiology and Pathophysiology" was held September 26-29, 1991, at the Engineering Society Club of Baltimore. The conference was organized by a committee consisting of John Williams of the University of Michigan (Co-Chair), Daniel Longnecker of Dartmouth Medical School (Co-Chair), Barry Agent of Newcastle Upon Tyne, Raymond Frizzell of the University of Alabama at Birmingham, Sherwood Githens of the University of New Orleans, and Sarah Kalser of the NIDDK. The meeting was sponsored by the NIDDK with contributions from NCI, NIDR, ADAMHA, and the American Gastroenterological Association. About 100 investigators from the United States, England, Canada, Germany, Norway, and Israel attended the conference. The participants were based in a number of distinct disciplines including both basic and clinical sciences. While the main focus was on pancreatic ducts, comparison of salivary and bile ducts was also included.
