[摘 要] 目的:探讨不同性别来源人胚胎干细胞外泌体(human embryonic stem cell⁃derived exosome,hESC⁃exo)和人羊膜间充
质干细胞外泌体(human amniotic mesenchymal stem cell⁃derived exosome,hAMSC⁃exo)在蛋白质组学和转录组学层面的差异。
方法:构建符合外泌体研究的培养体系,通过超速离心分别从男女株人胚胎干细胞(human embryonic stem cell,hESC)和人羊膜
间充质干细胞(human amniotic mesenchymal stem cell,hAMSC)中获得质量符合研究要求的外泌体(exosome,exo),采用液相色
谱⁃串联质谱(liquid chromatography⁃tandem mass spectrometry,LC⁃MS/MS)分析来定义蛋白质组学表征,进行高通量测序以确定
微小RNA(microRNA,miRNA)谱。通过生物信息学分析确定外泌体调控的主要生物学过程和通路。结果:在蛋白质组学和转
录组学层面,hAMSC⁃exo男株与女株表征类似,而hESC⁃exo男株与女株间存在较大差异。miRNA图谱和蛋白质组分析揭示了
hESC⁃exo主要与发育、代谢相关,hAMSC⁃exo主要与免疫、代谢相关。结论:通过蛋白质组学和miRNA测序对不同性别来源的
hAMSC⁃exo和hESC⁃exo进行了系统分析,预测它们的生物学功能,揭示其在不同领域的应用潜力,为临床前和临床试验中选择
更优来源细胞提供新的视角。

[Abstract] Objective:To investigate proteomic and transcriptomic differences between exosomes derived from sex⁃specific human
embryonic stem cells(hESC⁃exo)and human amniotic mesenchymal stem cells(hAMSC⁃exo)at the molecular level. Methods:A
defined cell culture system optimized for exosome research was established. High ⁃ quality exosomes were isolated via
ultracentrifugation from male and female lines of hESCs and hAMSCs. Proteomic characterization was performed using liquid
chromatography⁃tandem mass spectrometry(LC⁃MS/MS),while microRNA(miRNA)profiles were determined by high⁃throughput
sequencing. Bioinformatics analysis subsequently identified key biological processes and pathways regulated by the exosomes. Results:
At both proteomic and transcriptomic levels,exosomes derived from male and female hAMSCs exhibited similar molecular profiles,
whereas those originating from male and female hESCs showed significant sex ⁃ based differences. Integrated miRNA profiling and
proteomic analysis revealed that hESC⁃exo were primarily associated with developmental and metabolic processes,while hAMSC⁃exo
predominantly participated in immune and metabolic functions. Conclusion:Through systematic proteomic and miRNA sequencing
analyses of sex⁃specific exosomes derived from hAMSCs and hESCs,this study predicted their biological functions and revealed their
