The scientists at University of Pennsylvania School of Medicine discovered that it is possible to regenerate damaged cells of the pancreas. Although the cells that revealed this discovery are not the beta cells of the pancreas, researchers believe that this research could find new ways to replenish the organs ability to produce insulin in diabetics.
The pancreas is made up of two compartments with different functions: the islet compartment of insulin-producing beta cells and the much larger exocrine compartment composed of duct cells and acinar cells that make and deliver enzymes to the intestine for digestion. Diabetes is caused by the failure of the beta cells to make insulin, whereas pancreatic cancer usually originates from the exocrine compartment. Under certain conditions in tissue culture, acinar cells can synthesize insulin as well as amylase, a digestion enzyme.
Evidence from this research is pointing to the beta cell itself as the most promising source for generating new beta cells. The focus of research is now shifting toward the direct stimulation of islet cell growth in live animals. In contrast, once acinar cells are removed from the organism and placed into culture, they may have greater potential to change into other cell types, including beta cells. As a result, Stoffers' animal model and technical approach is currently being used by other groups in the United States, Europe, and China to determine conditions under which acinar cells can take on the features of duct cells and beta cells.
1. Can we then say, that there will be no assault upon these new regenerated cells by our Immune System?
This is all very much speculative because this procedure has not even taken place:
"conditions under which acinar cells can take on the features of duct cells and beta cells.
