Pancreatic islet cell transplantation is the transfer of islet cells from a donor pancreas to another person. Islet cells contain beta cells that the body needs to make insulin. Type 1 diabetes happens when the body's immune system attacks and destroys beta cells. Newly transplanted islet cells can make insulin. This may reduce or eliminate the need for insulin injections.
The procedure is being studied as a method to treat people with chronic, uncontrolled type 1 (and some type 2) diabetes.
This procedure may be done on people with severe hypoglycemia (low blood glucose) and those who cannot control their diabetes using other methods.
