摘要：Methods and compositions are described for the treatment of type I insulin-dependent diabetes mellitus and other conditions using newly identified stem cells thatare capable of differentiation into a variety of pancreatic islet cells, including insulin-producing beta cells, as well as hepatocytes. Nestin has been identified as a molecularmarker for pancreatic stem cells, while cytokeratin-19 serves as a marker for a distinctclass of islet ductal cells. Methods are described whereby nestin-positive stem cells canbe isolated from pancreatic islets and cultured to obtain further stem cells or pseudo-islet like structures. Methods for ex vivo differentiation of the pancreatic stem cells aredisclosed. Methods are described whereby pancreatic stem cells can be isolated,expanded, and transplanted into a patient in need thereof, either allogeneically,isogeneically or xenogenically, to provide replacement for lost or damaged insulin-secreting cells or other cells.
