Abstract (en)

[origin: WO9838283A1] Methods are described for selecting germ-line competent cells in stage X (E-G & K) chicken embryos comprising selecting cells from a stage X (E-G & K) chicken embryo which have an epitope expressed by germ-line competent cells associated with their cell surface. The epitope may be EMA-1 or SSEA-1, for example. Methods for producing a chimeric chicken embryo and a chimeric chicken using the selected germ-line competent cells are also described.
