Research on Prenatal Diagnosis Using People's Appearance

Abstract

Fetal diagnosis using villi in early pregnancy is a problem that the medical community at home and abroad is concerned about. Han Anguo (1975) was the first to take villi cells from the cervix into the uterine cavity for fetal sex determination. Since June 1983, our department has carried out research on the method of taking microvilli through the cervix in early pregnancy, the method of preparing villous chromosomes and the method of extracting DNA from villus cells, and these methods have been applied to clinical practice, and are now reported in Down.
