Abstract
Summary. Treatment of preimplantation mouse embryos in vitro with 10−3 to 10−1 μg actinomycin D/ml for 2 hr showed that (i) postimplantation development in vitro was inhibited most when embryos were treated at the morula stage and (ii) after the morula stage actinomycin D inhibited trophoblast outgrowth less than inner cell mass development.Keywords
