从孕母体循环中获取胎儿细胞并进行分析是一种对胎儿无任何风险的诊断途径。本文以聚合酶链反应(PCR)法扩增Y染色体上一个248hp的片段,从而成功地从孕母血中检测到胎儿细胞。
Getting fetus cells from the maternal cycle and analyzing them is a diagnostic route without any risk to the fetus. In this paper, a 248-bp fragment of Y chromosome was amplified by polymerase chain reaction (PCR) to successfully detect fetal cells from maternal blood.
