| Title: | Homologous recombination for universal donor cells and chimeric mammalian hosts | | Inventors: | Kucherlapati, Raju; Darien, CT, USA

Smithies, Oliver; Chapel Hill, NC, USA | | Summary: | This invention describes a method by which homologous recombination is employed to inactivate genes associated with MHC antigens. Described herein are novel genetically engineered cells having lesions at the ?2 -microglobulin loci which results in cells lacking Class I MHC antigens and which may be used as universal donor cells. Further disclosed are methods by which embryonic stem cells may be modified by homologous recombination for use in producing chimeric or transgenic mammalian hosts which in turn may be used as a source of universal donor organs and as models for drug and transplantation therapies. | | 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 Class I MHC antigens. The resulting cells may be used as universal donors. 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. | | US Patent Website: | Click Here for Full Text of Patent | | Title Number: | US5413923 | | Application Number: | US1992000990879 | | Date Filed: | 11/12/1992 | | Date Published: | 09/05/1995 | | Assignee: | Cell Genesys, Inc., Foster City, CA, USA
