  • Publication number: 20070020242
    Abstract: The subject invention relates to a method of transdifferentiating mammalian non-pancreatic stem cells, such a mesenchymal stem cells (MSCs), to enter the pancreatic differentiation pathway. The MSCs are cultured under conditions that permit the expression of pancreatic differentiation markers, and these conditions include use of: (a) culture conditions that promote cell clustering; and/or (b) medium comprising glucagon-like peptide-1 (GLP-1), hepatocyte growth factor (HGF) and/or nicotinamide.

  • Patent number: 6703017
    Abstract: The subject invention concerns new methods which make it possible, for the first time, to grow functional islet-producing stem cells (IPSCs), islet progenitor cells (IPCs) and IPC-derived islets (IdIs) in in vitro cultures. The subject invention also concerns the use of the in vitro grown IPSCs, IPCs and/or IdIs for implantation into a mammal for in vivo therapy of diabetes. The subject invention further concerns a process of using the implanted cells for growing a pancreas-like structure in vivo that has the same functional, morphological and histological characteristics as those observed in normal pancreatic endocrine tissue. The ability to grow these cells in vitro and pancreas-like structures in vivo opens up important new avenues for research and therapy relating to diabetes.

  • Patent number: 6699469
    Abstract: This invention provides materials and procedures for the delivery of selected strains of bacteria and/or oxalate-degrading enzymes to the intestinal tracts of persons and/or domestic or zoological animals who are at increased risk for oxalate related disease because they have lost, or have inadequate concentrations of these bacteria. The administration of these bacteria and/or the relevant enzyme removes oxalate from the intestinal tract and thus reduces the amount of oxalate available for absorption and reduces the risk for oxalate related disease.

  • Patent number: 6001647
    Abstract: The subject invention concerns new methods which make it possible, for the first time, to grow functional islets in in vitro cultures. The subject invention also concerns the use of the in vitro grown islet-like structures for implantation into a mammal for in vivo therapy of diabetes. The subject invention further concerns a process using the in vitro grown islet implants for growing an organ in vivo that has the same functional, morphological and histological characteristics as those observed in normal pancreatic tissue. The ability to grow these cells in vitro and organs in vivo opens up important new avenues for research and therapy relating to diabetes.
