Trophoblast cells circulating in peripheral venous blood during pregnancy were extracted by differential centrifugation and identified by indirect immunofluorescence with antitrophoblast microvillus antibody. In a study where trophoblast identification was checked by blind comparison with non-pregnant control subjects' trophoblast cells were detected in six out of 10 pregnant women studied.
孕期外周静脉血中循环的滋养层细胞通过差速离心法提取,并用抗滋养层微绒毛抗体进行间接免疫荧光鉴定。在一项研究中,通过与未怀孕对照受试者进行盲法比较来检查滋养层细胞的鉴定情况,在所研究的10名孕妇中,有6名检测到了滋养层细胞。
