Islets isolated from a cadaver donor pancreas were resuspended in buffer, transferred to a transfusion bag, and infused over 20 min through the catheter into her portal vein (Fig.
Infused islets were then carried by her blood to smaller branches of the portal vein, where they lodged, engrafted, and resumed tightly controlled secretion of insulin in response to her blood sugar levels.
Islet transplants for the treatment of diabetes are being covered by several provinces in Canada, where a landmark pilot clinical trial called the Edmonton Protocol was performed in 2000.
