绒毛细胞
方法绒毛细胞培养法及G显带制作染色体分析。
The improvement of the main problems arising in the course of direct preparation of villus cell chromosomes has been illustrated, and the relative problems have been discussed.对绒毛细胞直接制备染色体过程中存在的一些主要问题,在技术上进行了改进,并就有关问题加以讨论。
Results: 72-100% of peripheral blood lymphocyte metaphases or inter-phases, 60- 70% of amniocyte interphases, and 95-99% of chorionic villus cell interphases showed expected signals.结果:72~100%外周血淋巴细胞中期相或间期核、60~70%羊水细胞间期核、95~99%绒毛细胞间期核显示预期信号。
