In a mediumof TC199 + 10% FCS, three quarters of the fertilized eggs developed to the blastocyst stage. Noapparent change of the injected gene was found before the 8-cell stage, after which it was eitherintegrated into the chromosome of the host or lost gradually. But finally, the retention rate of theinjected gene should be equal to its integration rate.展开更多
