研究目的:

1. 通过单细胞RNA测序技术,绘制人类妊娠早期母胎界面细胞图谱,寻找RSA患者与正常妊娠女性母胎界面免疫细胞相关的差异转录基因,借助空间转录组平台,对母胎界面细胞图谱进行验证,观测子宫蜕膜中不同部位功能区基因表达的差异,构建母胎免疫细胞通讯网络,并寻找与蜕膜巨噬细胞相关的关键转录基因及信号转导通路。 2. 探索RSA患者蜕膜巨噬细胞增殖、凋亡水平、细胞吞噬功能、胞葬功能及M1、M2型巨噬细胞极化路径相关因子表达差异 通过观察RSA患者与正常妊娠女性蜕膜组织辅助性T细胞Th1、Th2数量,巨噬细胞M1、M2型细胞数量及巨噬细胞M1、M2极化路径相关因子PERK、ATF-4、PSAT1、α-KG、p-JAK、p-STAT1表达水平、蜕膜巨噬细胞增殖、凋亡、细胞吞噬、胞葬功能,探索RSA患者蜕膜巨噬细胞功能及极化路径相关因子表达水平的差异。  

Objectives of Study:

1. Single cell RNA sequencing technology was used to map the maternal/fetal interface cell map in the early stage of human pregnancy, search for differential transcriptional genes related to maternal/fetal interface immune cells in RSA patients and normal pregnant women, verify the maternal/fetal interface cell map with the help of spatial transcriptome platform, and observe the differences in gene expression in functional regions of different parts of decidua. The communication network of maternal-fetal immune cells was constructed, and the key transcription genes and signal transduction pathways related to decidual macrophages were searched. 2. To explore the differences in the proliferation and apoptosis levels of decidual macrophages in RSA patients, cytophagocytosis and cytoburial functions, and the expression of factors related to the polarization pathway of M1 and M2 macrophages. By observing the number of helper T cells Th1 and Th2 in decidual tissue between RSA patients and normal pregnant women, The number of macrophage M1 and M2 type cells, the expression levels of macrophage M1, M2 polarization path-related factors PERK, ATF-4, PSAT1, α-KG, p-JAK, p-STAT1, the proliferation, apoptosis, phagocytosis, and cytoburial function of decidual macrophages, To explore the differences in the function of decidual macrophages and the expression levels of polarization pathway-related factors in RSA patients.
