    摘要: A transgenic animal such as a transgenic snake or other reptile that expresses a heterologous expression product is described, along with methods of making the same. In general, the animal comprises cells containing a sequence encoding the heterologous expression product. The sequence encoding the heterologous expression product is integrated into the genome of the animal (e.g., in some or all cells thereof, and in some embodiments into germ cells thereof). The sequence encoding the heterologous expression product is, in general, operatively associated with an expression sequence or promoter. The animals are useful for, among other things, testing of repellents, testing of toxicological compounds, as teaching aids, for venom production, etc.

    摘要: A method of producing undifferentiated avian cells expressing an embryonic stem cell phenotype. The method includes the steps of collecting avian gonadal cells including primordial germ cells from an avian embryo after the formation of the primitive streak; depositing the avian gonadal cells in contact with a preconditioned feeder matrix; and growing the avian gonadal cells on the pre-conditioned feeder matrix in the presence of media for a time sufficient to produce an avian cell culture consisting essentially of undifferentiated avian cells expressing an embryonic stem cell phenotype.

In one embodiment, the presently disclosed subject matter provides a method for modulating primordial germ cells numbers in an avian embryo comprising immunizing a female bird with an antigen associated with primordial germ cells, whereby an egg produced by the female bird comprises a sufficiently high concentration of antibodies specific for the antigen to modulate numbers of endogenous PGCs in an avian embryo present within in the egg. Also provided are methods for producing chimeric avians, methods for increasing the proportion of male birds in a plurality of eggs, methods of producing avian gametes, and methods for enhancing germ line transmission of nucleic acids in birds.

    摘要: A method for the production and collection of avian sperm comprises the steps of: providing primordial germ cells from a donor avian species; administering the primordial germ cells to a recipient avian species in ovo; incubating the recipient avian species to hatch; and then collecting sperm of the donor avian species from the recipient avian species. For example, the donor avian species may be a whooping crane, and the recipient avian species may be a sand hill crane. In another example, the donor avian species may be a turkey, and the recipient avian species may be a chicken.
