Defects in β-cell Ca2+ dynamics in age-induced diabetes.

abstract：:Isologous pancreatic islets were implanted into the portal vein of rats with streptozotocin-induced diabetes. At intervals of from one to 32 days after transplantation, the intrahepatic islet grafts were examined histologically and ultrastructurally, and their vascular supply was determined by later perfusion studies....
