人类体外受精试验的成功给生殖生物学领域打开了新的局面。但根据资料报导,人工受精的成功率是很低的,而且人工受精的流产儿中有染色体异常。因此,在体外受精的研究上,正在开展与人类生殖的基本问题有关课题的探讨。已有一些人报导过哺乳动物卵细胞的染色体分析,对人卵细胞的研究也有2、3份报告资料。但在方法学上都有一些问题,因此,对减数分裂过程中的染色体动态,至今仍未弄清。作者将Tarkowski的方法加予
The success of human in vitro fertilization tests opens a new dimension to the field of reproductive biology. However, according to the data reported, the success rate of artificial insemination is very low, and artificial insemination of abortion children with chromosomal abnormalities. Therefore, in vitro fertilization research, is carrying out and human reproduction of the basic issues related topics. Some people have reported chromosomal analysis of mammalian egg cells. There are also 2,3 reports on human egg cells. However, there are some methodological problems, therefore, the chromosome dynamics during meiosis have not yet been clarified. The author adds Tarkowski’s approach
