  • Chimeric bird from embryonic stem cells
    Patent number: 7145057
    Abstract: Sustained cultures of avian embryonic stem cells are provided. Injection of avian embryonic stem cells into recipient embryos yields chimeras with a significant contribution from the embryonic stem cell phenotype. Transgene encoding exogenous proteins are stably integrated in the embryonic stem cells and are present in the somatic tissue of the resulting chimeras. The transgenes may encode exogenous proteins expressed in endodermal, ectodermal, mesodermal, or extra embryonic tissue. Breeding the resulting chimera yields transgenic birds whose genome is comprised of exogenous DNA.
    Type: Grant
    Filed: February 1, 2002
    Date of Patent: December 5, 2006
    Assignee: Origen Therapeutics, Inc.
    Inventors: Marie-Cecile Van de Lavoir, Robert J. Etches, Babette Heyer, Jennifer Diamond, Christine Mather, Kathleen Beemer, Heather Myers
