  • Patent number: 6514752
    Abstract: Homologous recombination is employed to inactivate genes, particularly genes associated with MHC antigens. Particularly, the &bgr;2-microglobulin gene is inactivated for reducing or eliminating the expression of functional Class I MHC antigens. The resulting cells may be used as universal donor cells. In addition, embryonic stem cells may be modified by homologous recombination for use in producing chimeric or transgenic mammalian hosts, which may be used as source of universal donor organs, or as models for drug and transplantation therapies. Methods for homologous recombination in non-transformed mammalian somatic cells are also described.
    Type: Grant
    Filed: May 18, 1995
    Date of Patent: February 4, 2003
    Assignee: Cell Genesys, Inc.
    Inventors: Raju Kucherlapati, Beverly H. Koller, Oliver Smithies, Robert B. Dubridge, Gary Greenburg, Daniel J. Capon, Steven R. Williams, Mariona Lourdes Arbones De Rafael
  • Patent number: 6139835
    Abstract: Homologous recombination is employed to inactivate genes, particularly genes associated with MHC antigens. Particularly, the .beta..sub.2- microglobulin gene is inactivated for reducing or eliminating the expression of functional Class I MHC antigens. The resulting cells may be used as allogeneic donor cells. Methods for homologous recombination in non-transformed mammalian somatic cells are also described.
    Type: Grant
    Filed: May 18, 1995
    Date of Patent: October 31, 2000
    Assignee: Cell Genesys, Inc.
    Inventors: Raju Kucherlapati, Beverly H. Koller, Oliver Smithies, Robert B. Dubridge, Gary Greenburg, Daniel J. Capon, Steven R. Williams, Mariona Lourdes Arbones De Rafael
  • Patent number: 5574205
    Abstract: Homologous recombination is employed to inactivate genes, particularly genes associated with MHC antigens. Particularly, each of the .beta..sub.2- microglobulin gene and the IFN-.gamma.R gene is inactivated for reducing or eliminating the expression of functional MHC antigens. The resulting cells may be used as universal donor cells. In addition, embryonic stem cells may be modified by homologous recombination for use in producing chimeric or transgenic mammalian hosts, which may be used as source of universal donor organs, or as models for drug and transplantation therapies. Methods for homologous recombination in non-transformed mammalian somatic cells are also described.
