根据组织病理学特点及基因来源,葡萄胎可分为部分性葡萄胎和完全性葡萄胎。葡萄胎的类型及组织来源的判断除可采用组织病理学的方法外,还可采用STR基因座检测的方法。根据葡萄胎的类型、组织来源及受精方式,利用群体遗传学的原理和方法对葡萄胎进行亲缘关系鉴定。 According to histopathological characteristics and gene sources, hydatidiform mole can be divided into partial hydatidiform mole and complete hydatidiform mole. Mole type and tissue source judgments in addition to the use of histopathological methods, but also can be used STR locus detection method. According to the type of hydatidiform mole, the source of tissue and the method of fertilization, the hydatidiform mole was identified by using the principles and methods of population genetics.
