Abstract： @@ 由于孕妇外周血中胎儿细胞的含量极少,Hahn, Holzgreve[1]和Bianchi等[2]报道,孕妇每毫升外周血中仅有1～2个完整胎儿细胞.所以采用特异性单克隆抗体对胎儿细胞进行标记,并结合流式细胞仪进行高效富集分选的技术,是分离、纯化孕妇外周血中胎儿细胞的最佳手段[3].但因目前尚未发现识别胎儿细胞的特异性抗体,故不同学者选用的标记性抗体也有所不同.本研究采用荧光激活细胞分离技术(fluorescence-activated cell sorting,FACS ),通过对孕妇外周血及未孕妇女外周血中转铁蛋白受体(transferrin receptor, CD71)单标记染色和胎儿血红蛋白(fetal haemoglobin,HbF)单标记染色与双标记染色情况的比较,探讨CD71 与HbF染色法分选胎儿有核红细胞的价值.
