| Outline of Final Research Achievements |
Although clinical research of islet transplantation for type 1 diabetes has starts in Japan, severe donor shortage hampers the progress. A possible solution is use of marginal donors such as donors after cardiac death (DCD). A continuous hypothermic perfusion machine, LifePortTM(LP), used for preservation and transportation of marginal kidney for organ transplantation. The effectiveness has been approved especially in the preservation. We applied LP to preservation of pancreas that is sensitive to ischemia reperfusion injury and found that the machine would be efficacious on islet isolation..
In experimental DCD pancreas canine model, continuous hypothermic machine perfusion resulted in higher recovery and function of islets than simple cold storage and two layer method. Further improvement will achieve clinical application of the method on DCD pancreas preservation.
