| Outline of Final Research Achievements |
The aim of this study is to fabricate of islet cell sheet using porcine islets and to laminate endothelial cells and pancreatic ductal cells with islet cells in order to develop the blood supply and the islet function in the transplantation sites. The islet cell sheets of porcine islets were fabricated by using the temperature-responsive culture dishes. The endothelial cells sheets were laminated with islet cells, and the hybrid tissue was transplanted into the subcutaneous space of the diabetic mice without any complication. It was impossible to isolate the pancreatic ductal cells from pancreas. This study indicated that the fabrication of multi-layered islet cell sheets could result in further development of the therapeutic effect for diabetic mellitus.
