Although embryo transfer(ET)was first successfully performed in the last century,the technique attracted relatively little attention prior  to 1950,and as a result,probably in excess of 95% of the published work in this field has appeared in the last 30 years.Since the 1970s the technique has been not only in laboratory investigations,but also for practical application to livestock improvement and production.Many commercial embryo transfer organizations have been established,particularly in North America.The research and development of embryo transfer in China is much latter than developed countries.The first record of successful embryo transfer in China was in 1973.This technique has enabled the development of new technologies associated with the manipulation of oocytes and embryos.In the last ten years rapid progress has been made in China,including artificial insemination,embryo transfer,in vitro fertilization,microinsemination,oocyte activation and parthenogenetic development,embryo bisection,nuclear transfer,embryo sexing,oocyte and embryo preservation,transgenic animals and so on.So those techniques of gamete and embryo micromanipulation in vitro have been formed the systematic embryo engineering....

虽然动物胚胎移植在上世纪末首次获得成功,但在1950年之前并未被引起重视。该领域中95%以上的文献是近30年发表的。70年代以来不仅在实验室研究此类技术,而且已将其应用于家畜的改良和生产。尤其是在北美,已建立了许多商业性的胚胎移植机构。中国的胚胎移植研究及其发展较晚,首次胚胎移植成功的记录是在1973年。结合卵母细胞和胚胎体外操作,使这一技术衍生出了更多的新技术。近10余年来,在人工授精、胚胎移植、体外受精、显微授精、卵母细胞激活与孤雌发育、胚胎分割、细胞核移植、胚胎性别鉴定、卵母细胞和胚胎保存以及转基因动物等方面,中国已得到迅速发展。这些配子和胚胎的体外显微操作技术已形成了系统的胚胎工程学。文章将对这一学科在中国的发展作一简要论述。
