Almost 80 years ago, Dr. Frederick Banting published a report about use of pancreatic Islets to treat diabetes. He obtained those Islets from the pancreas of a dog. By first tying-off that pancreas, he eliminated the digestive enzymes that would otherwise have destroyed the insulin in the Islets.

Type 1 diabetes is a very serious disorder that impacts the day to day existence of the people that suffer from it. While there are many effective treatment options for type 1
diabetes there is still no cure. While there are several potential technologies on the horizon that promise to lessen or even eliminate the worst effects of the disease, such
as the closed loop insulin pump (sometimes inaccurately called an artificial pancreas) and pancreas transfers, the technology that holds the most promise is the islet cell
transplant.
