| Outline of Final Research Achievements |
Islet transplantation is considered as an option for the treatment of type 1 diabetes. However, transplanted islets face several challenges, including Blood type and Human leukocyte antigen mismatches. In addition, islet isolation is still complicated and technically difficult in some cases. Therefore, the cases of mismatches and islets with a low yield at isolation are not transplanted and distributed for basic research. To allow the unlimited collection of islets, islet cryopreservation methods need to be optimized. In this regards, the pancreatic islet sheet may provide a promising option for cryopreserving islets. A library of cryopreserved islets allows for selection based on HLA tissue type and creates more flexibility regarding the total amount of transplantable mass. The present study aimed at establishing a new cryopreservation method for pig pancreatic islet sheet by vitrification and an evaluation method by a high-throughput sequencing
