Seeding of pancreatic islets into prevascularized tissue engineering chambers.

Transplantation of islets into the portal vein of diabetic patients has emerged as a promising procedure for the treatment of type 1 diabetes. However, shortages of donors and adverse effects leading to graft impairment and/or rejection have prevented this procedure from achieving widespread clinical application. The aim of this study was to develop a method that could support the survival and function of transplanted islets using a prevascularized tissue engineering chamber.
