[The presentation of neo gene in chimeric mice obtained from ES cells].
To explore the potentiality of the mouse ES cell line which is employed in our laboratory were transfected with neo gene and selected with G418. Some ES cell clones expressing neo gene were obtained. After ES clones were picked up and expanded, the ES cells were mircoinjected into blastocysts and implanted miceuterus. 60 blastocysts were implanted into 5 mice. Finally, 3 chimeric mice with neo gene were born. PCR was carried out to analyze the presentation of neo gene in tissues of chimeric mice. The results showed that many tissues harbored the neo gene, including skin, liver and blood et al.
