由于对分娩准备和启动的了解有限,分娩的潜在机制在很大程度上仍然难以捉摸。越来越多的证据表明,母体蜕膜在分娩启动中起着关键作用。为了全面解密接近分娩的蜕膜中的细胞异质性,我们研究了各种细胞类型在小鼠蜕膜过程中的作用,并利用单细胞RNA测序(scRNA-seq)揭示了分娩启动中以前未被认识的见解。我们列举了蜕膜中的细胞类型,并鉴定了五种不同的基质细胞群和一种蜕膜化基质细胞。此外,我们的研究揭示了基质细胞通过调节局部视黄醇酸(RA)的合成为分娩做准备。RA补充剂在体外降低细胞外基质相关基因的表达,并在体内加速分娩时间。总的来说,基质细胞在分娩中的贡献的发现扩展了当前有关分娩的知识,并为早产(PTB)的干预开辟了途径。基质细胞是小鼠蜕膜中最丰富的细胞类型,RA是分娩发动的潜在蜕膜关键因素,RA通过调节ECM基因参与分娩基质细胞主导与其他细胞类型的复杂相互作用妇女健康;细胞生物学
The underlying mechanisms governing parturition remain largely elusive due to limited knowledge of parturition preparation and initiation. Accumulated evidences indicate that maternal decidua plays a critical role in parturition initiation. To comprehensively decrypt the cell heterogeneity in decidua approaching parturition, we investigate the roles of various cell types in mouse decidua process and reveal previously unappreciated insights in parturition initiation utilizing single-cell RNA sequencing (scRNA-seq). We enumerate the cell types in decidua and identity five different stromal cells populations and one decidualized stromal cells. Furthermore, our study unravels that stromal cells prepare for parturition by regulating local retinol acid (RA) synthesis. RA supplement decreases expression of extracellular matrix-related genes in vitro and accelerates the timing of parturition in vivo. Collectively, the discovery of contribution of stromal cells in parturition expands current knowledge about parturition and opens up avenues for the intervention of preterm birth (PTB). Stromal cells are the most abundant cell type in mice decidua RA is a potential decidual critical factor for labor onset RA participates in parturition by regulating ECM genes Stromal cells dominate the complex interactions with other cell types Women's health; Cell biology
