Abstract:
:The objective of this study was to define pretransplant islet culture conditions for optimum tissue engraftment in the rat islet allotransplantation model. Lewis rat islets were cultured in TCM 199/5% fetal calf serum for I day at 37 degrees C, followed by 1 day of culture at 22 degrees C. When islets from single donors were allotransplanted intraportally into single streptozotocin-diabetic Wistar-Furth rats, complete normoglycemia was restored within 1 day after transplantation in seven out of seven rats, and persisted up to immunological rejection about 1 week later. In five out of six rats receiving a posttransplant injection of antilymphocyte serum, plasma glucose was normalized for >100 days. These data demonstrate, for the first time, successful single-donor-to-single-recipient transplantation of allogeneic rat pancreatic islets. Because islet engraftment may still be regarded as a main problem for clinical islet transplantation, the pretransplant islet culture regimen outlined in this article may lead to a more efficient use of donor pancreatic islet tissue in the clinical setting, as well.
