种植前遗传学诊断(PGD)近年来成功地运用于生殖领域,对有高风险生育夫妇的种植前胚胎进行非整倍体和单基因异常的检测,避免种植异常胚胎,从而增加生育正常后代的机率。PGD常用极体或卵裂球活检2种方法。旨在以提供一种可增加用于遗传病诊断的DNA数量的方法;同时监测胚胎形态、
Preimplantation genetic diagnosis (PGD) has been successfully used in the reproductive field in recent years to detect aneuploidy and single gene anomalies in preimplantation embryos of couples with high risk of birth, to avoid planting abnormal embryos and to increase the Chance PGD commonly used polar body or blastomere biopsy 2 ways. Aims to provide a method that can increase the amount of DNA used for the diagnosis of genetic diseases; simultaneously monitor embryonic morphology,
