自1983年意大利Simoni等报导绒毛直接法制备染色体技术,以来,以绒毛细胞进行产前诊断已为国内外科研工作者所嘱目。该项技术既快速,又准确,是产前诊断研究的一大突破,已成为优生科学和预防医学的一个新的方向。我们参考Simoni的方法,根据我实验室的条件,加以改进。半年多来,我们共进行80余例实验,取得了满意的效果。现将操作方法作一介绍。 Since 1983, Italy, such as Simoni reported villus direct chromosome preparation technology, since the villus cells for prenatal diagnosis has been the goal of scientific research workers at home and abroad. This technique is both rapid and accurate, and is a breakthrough in prenatal diagnosis research. It has become a new direction of eugenics and preventive medicine. We refer to Simoni’s method, according to my laboratory conditions, to be improved. Over the past six months, we conducted more than 80 experiments in total and achieved satisfactory results. Now the operation method for an introduction.
