Abstract : the early embryo developmental block is a common phenomenon in mammal when embryos are cultured in vitro. many studies of phosphorus, glucose, hypoxanthine and cytoplasmic factors on early embryo developmental block carried out by different methods such as morphology, biochemistry, molecular biology and micromanipulation have been reviewed. the merit and shortcoming were analyzed and the necessity of using simple or components limited media overcoming early embryo developmental block were also reviewed. media that have been shown effective in overcoming early embryo developmental block in mouse, rat, hamster, rabbit, pig, sheep, cattle and monkey were listed
摘要哺乳動物胚胎在體外培養中普遍存在早期發育阻滯的現象.對此,人們用形態學、生物化學、分子生物學、顯微操作等手段開展了磷酸、葡萄糖、次黃嘌呤和細胞質因素對早期胚胎發育阻滯的影響的研究.本文綜合分析了共培養系統的優缺點.說明了採用完全成分已知的培養液對進行有關研究的必要性.列出了有效運用於克服小鼠、大鼠、倉鼠、兔、豬、羊、牛、猴等動物早期胚胎阻滯的成分已知的培養液的名稱。In order to understand how darwin builds a long argument to persuade readers to believe his evolutionary theory is better than creationism and lamarck ' s transmutation theory, one needs to know the emergence of this revolutionarily scientific theory is not only related to geology, paleontology, comparative anatomy, morphology, and embryology but also connected with his contemporary background of religion as well as economy
