Abstract/OtherAbstract:
In the course of investigating the signals associated with pancreas regeneration, we have developed a method to initiate pancreatic duct cell proliferation by brief occlusion of the main pancreatic duct. The resulting duct cell proliferation, induced by temporary partial main duct occlusion, was compared to that induced by firmly tying a cellophane strip around the head of the pancreas for longer periods of time. Both methods stimulated a biphasic increase in duct cell proliferation, with proliferation maxima at 3 and 14 days post operation. The short duration of temporary main duct occlusion (60 s) that was needed to stimulate duct cell proliferation, and the similar duct cell proliferation profiles that were observed after both the temporary and the longer term main duct occlusion, led us to conclude that the signals which initiate proliferation occur rapidly at the beginning of each procedure.
