摘要 Identifying the origin of body fluids left at a crime scene can give a significant insight into crime scene reconstruction by supporting a link between sample donors and actual criminal acts.However,the conventional body fluid identification methods are prone to various limitations,such as time consumption,intensive labor,nonparallel manner,varying degrees of sensitivity and limited specificity.Recently,the analysis of cell-specific messenger RNA expression(mRNA profiling)has been proposed to supplant conventional methods for body fluid identification.Since 2011,the collaborative exercises have been organized by the European DNA Profiling Group(EDNAP)in order to evaluate the robustness and reproducibility of mRNA profiling for body fluid identification.The major advantages of mRNA profiling,compared to the conventional methods,include higher sensitivity,greater specificity,the ability of detecting several body fluids in one multiplex reaction,and compatibility with current DNA extraction and analysis procedure.In the current review,we provided an overview of the present knowledge and detection methodologies of mRNA profiling for forensic body fluid identification and discussed its possible practical application to forensic casework.
