About 10 percent of the more than 26 million Americans living with type 2 diabetes are also dependent upon insulin injections, and would presumably be candidates for beta cell transplants, Melton said.

Earlier studies suggested this process contributes to the high mortality and low insulin production often displayed in beta cell transplants, which aim to replace cells that the body's own immune system kills off in type 1 diabetes.

Not exact matches

At the very least, Domínguez - Bendala hopes that they could use BMP - 7 to convert the other 98 per cent of donor pancreas cells into beta cells, which, he estimates, could potentially provide enough insulin - producing cells to transplant into seven people.

Unlike transplanted beta cells — or other types of real cells genetically engineered to release insulin for diabetes treatment (SN: 1/15/11, p. 9)-- these artificial cells could be mass - produced and have a much longer shelf life than live cells, says study coauthor Zhen Gu, a biomedical engineer at the University of North Carolina at Chapel Hill.

Faustman got her idea by chance while transplanting islets, the pancreatic bodies that contain beta cells, from normal mice into others that had lost theirs to type 1, or juvenile, diabetes.

In the case of whole pancreas transplantation, major surgery is required; and in beta cell islet transplantation, the body's immune system can still attack the transplanted cells and kill off a large proportion of them (80 % in some cases).

«The loss of insulin - producing beta cells leads to type 1 diabetes, making it an ideal target for cell replacement therapy,» said James Shapiro, MD, PhD, FRCSC, Director of the Clinical Islet Transplant Program, University of Alberta.

In the study, which was conducted in collaboration with researchers at UC San Francisco and published today in the Journal of Neuroscience, scientists transplanted inhibitory neuron progenitors — early - stage brain cells that have the capacity to develop into mature inhibitory neurons — into two mouse models of Alzheimer's disease, apoE4 or apoE4 with accumulation of amyloid beta, another major contributor to Alzheimer's.

Islet transplants Insulin is normally produced by islet or beta cells in the pancreas.

The cell types involved in diabetes — the beta and immune cells — are being studied in the culture dish, as well as transplanted into lab animals.

Our efforts to monitor beta cells after transplant and identify signs of early demise in both native and transplanted cells will make it possible to stop cell injury, significantly advancing prevention efforts and strengthening transplant techniques.

To create a lasting source of insulin - producing beta cells for transplant, we are developing new methods to promote differentiation from pancreatic stem cells into healthy islets.

Nowadays, diabetics can choose an organ transplant in order to restore damaged pancreatic beta cells, but that's challenging route, restricted to a lack of organ donors, and individuals can wait years.
