摘要:
The present invention relates to a method for preparing commercial scale quantities of human functional beta cells and to the establishment of cell lines from non-foetal pancreatic tissues. It also relates to a method of diagnosis using beta cell tumors or cells derived thereof. The method comprises sub-transplantation procedure to enrich the graft in proliferating beta cells, allowing to generate human Beta cell lines. Such lines express, produce and secrete insulin upon glucose stimulation. They have a gene expression profile that resembles to adult beta cells. In addition, the human beta cell lines are able to normalize glycemia of diabetic mice when transplanted, demonstrating their insulin secretion capabilities.
