  • Publication number: 20190136196
    Abstract: The present invention relates to a method for preparing commercial scale quantities of human functional Betacells and to the establishment of cell lines. 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 Betacells, allowing to generate human Betacell lines. Such lines express little amount of insulin and have a gene expression profile that resembles to adult Betacells. In addition, the human Betacell lines are able to normalize glycemia of diabetic mice when transplanted, demonstrating their insulin secretion capabilities.

  • Patent number: 9493743
    Abstract: 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.

  • Patent number: 5902577
    Abstract: The invention relates to the field of biology and, in particular, to the field of cellular biology. The invention concerns a novel glucose-sensitive cell line designated .beta. cell line (INS-I) expressing glucokinase and the glucose carrier Glut 2 at levels comparable with those of normal .beta. cells but which is, in addition, incapable of IGF-II expression-dependent proliferation because of genetic manipulation. The invention also concerns a method for the production of said novel cell line, its aggregation in the form of a pseudoislet, its immobilization in a biocompatible hydrogel and its hardening by means of a hardening solution. Application in insulin-secreting .beta.-cell transplants.
