  • Exogenous protein expression system in an avian system
    Publication number: 20050227315
    Abstract: The invention concerns the use of an avian cell for producing an exogenous protein of interest in an animal belonging to the avian species, said cell being transformed by an expression vector comprising the gene coding for said protein, said cell being introduced in the sub-germinal cavity of an embryo, the blood stream of the embryo or being used as nucleus source for nuclear transfer into an avian egg enucleated or not, or whereof the chromosomes have been destroyed.
