根据人体胚胎发育的形态学证实,人体绒毛膜细胞具有与胎儿相同的遗传学特征.因此,应用孕早期6～10周绒毛细胞进行细胞遗传学、酶、激素、DNA分析等检测,即能反映胎儿的正常生理与异常病理状况.目前国内外已将绒毛开始应用于遗传性疾病的产前诊断.这种防治医学技术愈来愈引起人们的关注和社会的重视.七十年代,胎儿的遗传病之宫内诊断主要依赖羊膜囊穿刺,抽取羊水,进行细胞培养,以提供遗传学诊断的依据.利用羊水培养,作染色体核型分析、各种酶的生化测定
According to the morphology of human embryonic development confirmed that the human chorionic cells have the same genetic characteristics with the fetus.Therefore, the application of villus cells 6 to 10 weeks of pregnancy early detection of cytogenetics, enzymes, hormones, DNA analysis, which can reflect Fetal normal physiological and abnormal pathological conditions at home and abroad have been applied to the diagnosis of hereditary diseases villus prenatal diagnosis and treatment of this technology has drawn increasing attention and social attention .In the seventies, fetal genetic Intrauterine diagnosis of the disease mainly depends on amniotic sac puncture, amniotic fluid extraction, cell culture, to provide a basis for genetic diagnosis.Using amniotic fluid culture, chromosome karyotype analysis, biochemical determination of various enzymes
