Research Abstract

I established a novel imaging technique suitable for analysis of transplanted islets in liver using an optical projection tomography(OPT) method. A three-dimensional tomographic image of the transplanted islets in liver was reconstructed. The number of islets transplanted and the number of transplanted islets observed using OPT showed good correlation. The OPT method was used to compare the numbers of transplanted islets in mouse syngeneic and allogeneic transplantation models. In mice transplanted with allogeneic islets, the number and the volume of transplanted islets was significantly reduced in hyperglycemic condition of allogeneic transplantation. These results indicate that OPT imaging and analysis may be a useful tool to quantitatively and sterically evaluation of transplanted islets in liver at the cellular level.
