Islets are specialized cells present in the pancreas of the human body. They contain beta cells which produce insulin. In insulin dependent diabetics, replacement of healthy islets is a good option to cure the disease. In islet transplantation, the islets isolated from healthy dead donors are infused and placed in the pancreatic tissue. These new islets attach themselves to the blood vessels of the receiver, and then start producing fresh insulin to digest sugars in the body, thus curing diabetes.
