Abstract: This invention provides methods for the stable introduction of heterologous coding sequences into the genome of a bird and expressing the coding sequences to produce desired proteins or to alter the phenotype of the bird. The present invention provides preferred methods for introducing a transgene into the cytoplasm of avian embryonic cells by cytoplasmic microinjection. The embryo then develops into a transgenic adult capable of expressing a heterologous protein and/or capable of generating a line of transgenic birds through breeding. Synthetic vectors and gene promoters useful in the methods are also provided by the present invention, as are transgenic birds that express heterologous protein and avian eggs containing heterologous protein.

Abstract: The invention provides for transgenic avians containing nucleic acids which include an exogenous lysozyme gene expression controlling nucleotide sequence which typically is linked to a polynucleotide encoding a heterologous polypeptide.

Abstract: This invention provides vectors and methods for the stable introduction of exogenous nucleic acid sequences into the genome of avians in order to express the exogenous sequences to alter the phenotype of the avians or to produce desired proteins. In particular, transgenic avians are produced which express exogenous sequences in their oviducts and which deposit exogenous proteins into their eggs. Avian eggs that contain exogenous proteins are encompassed by this invention. The instant invention further provides novel forms of interferon and erythropoietin which are efficiently expressed in the oviduct of transgenic avians and deposited into avian eggs.

Abstract: The invention includes methods of producing viral particles which include introducing into avian cells a nucleotide sequence encoding a replication deficient retroviral vector and introducing into the avian cells nucleotide sequences encoding products required for replication of the replication deficient retroviral vector under the control of a promoter that is functional in the avian cell line, and harvesting the viral particles.

Abstract: This invention provides eggs which contain exogenous proteins. The invention further provides transgenic chickens which express exogenous sequences in their oviducts, and vectors and methods for the stable introduction of exogenous nucleic acid sequences into the genome of a bird for expressing said exogenous sequences to alter the phenotype of the bird or to produce desired proteins.
