mRNA在体液斑迹鉴定与组织来源推断中的应用

体液斑迹鉴定及其组织来源推断一直是法医学研究的重要方向之一,其传统的检验方法存在诸如假阳性率高、检材易破坏等缺陷,亟需更高效的确证实验。高度分化的体细胞表达特异的m RNA分子,可推断其来源:外周血、月经血、精液、唾液、阴道分泌物、接触斑等,且灵敏度、特异度及保存时间相对较为理想,是未来用于体液斑迹鉴别的理想遗传标记。本文对m RNA在体液斑迹鉴定和组织来源推断方面的应用及其前景进行综述。

The application of mRNA in body lfuid identiifcation and tissue resource(

The identiifcation of body lfuid and their tissue resource is an important part of forensic medicine research. Conventional methods have imperfections like high false positive rate and may destroy biomaterial, which should be replaced by a new conifrmatory test. Highly-differentiated cells express speciifc mRNA molecules that can be used for body lfuid identiifcation. These mRNA markers can identify body lfuids like peripheral blood, menstrual blood, semen, saliva, vaginal secretion, skin-contact stains. This method have favorable sensitivity, speciifcity and can be detected after years, made it a ideal way to identify current body lfuids in the future. This review focus on the application of mRNA in body lfuid identiifcation and tissue resource.
