21.   It occurs because islet cells, the insulin-producing cells of the pancreas, die, almost always because they are attacked by cells of the immune system.

22.   Last year Canadian researchers reported that transplants of human islet cells from donor organs had freed eight patients from the chore of daily insulin injections.

23.   Maybe the islet cell transplant was not necessary because once the scientists blocked the underlying disease, the pancreas could regenerate its own islet cells.

24.   Or they may have come from immature cells that originated elsewhere in the body and were stimulated to develop into islet cells by signals in the pancreas.

25.   Others have made devices that contain insulin-producing islet cells in the hope of closely mimicking the functions of the natural pancreas.

26.   Research continues on transplanting pancreatic islet cells for the same purpose.

27.   Researchers report promising results in the transplantation of insulin-producing islet cells into a damaged pancreas, a breakthrough that, if successful, would cure diabetes.

28.   Reemtsma spent his career seeking to transplant islet cells from the pancreas as a cure for diabetes.

29.   Seven monkeys received islet cells from other monkeys even though they were severely mismatched in blood and immune tests.

30.   Some proteins, including constituents of brain and the GAD protein in islet cells, are not on the thymus master list.
