Spatiotemporal insight into early pregnancy governed by immune-featured stromal cells [RNA-seq]

ABSTRACT: Endometrial decidualization connecting embryo implantation and placentation is transient, but essential for successful pregnancy, which however is not systematically investigated. Here, by using a novel single-cell spatial transcriptomic profiling technology (scStereo-seq), we were able to visualize and define key and dynamic functional decidual hubs assembled by distinct immune, endothelial, trophoblast and decidual stromal cells (DSCs) during early pregnancy in mice. We classified DSC subclusters and described their transdifferentiation trajectory controlled by transcription factor cascades. Interestingly, we discovered a novel type of DSCs expressing immune cell-specific genes, termed immune DSCs (iDSCs). Whereas immature DSCs attracted immune cells and induced decidual angiogenesis at the mesenchymal-to-epithelial transition (MET) hub during decidualization initiation, iDSCs enabled immune cell recruitment, angiogenesis facilitation and cytotoxic effect induction to form immune cell assembling and angiogenesis hubs, which eventually allow decidual homeostasis maintenance and decidualization-to-placentation transition. We spatiotemporally decode mouse early pregnancy events controlled by immune DSCs.

Spatiotemporal insight into early pregnancy governed by immune-featured stromal cells [Spatial Transcriptomics]

Project description:Endometrial decidualization connecting embryo implantation and placentation is transient but essential for successful pregnancy, which, however, is not systematically investigated. Here, we use a scStereo-seq technology to spatially visualize and deﬁne the dynamic functional decidual hubs assembled by distinct immune, endothelial, trophoblast, and decidual stromal cells (DSCs) in early pregnant mice. We unravel the DSC transdifferentiation trajectory and surprisingly discover a dual-featured type of immune-featured DSCs (iDSCs). We ﬁnd that immature DSCs attract immune cells and induce decidual angiogenesis at the mesenchymalepithelial transition hub during decidualization initiation. iDSCs enable immune cell recruitment and suppression, govern vascularization, and promote cytolysis at immune cell assembling and vascular hubs, respectively, to establish decidual homeostasis at a later stage. Interestingly, dysfunctional and spatially disordered iDSCs cause abnormal accumulation of immune cells in the vascular hub, which disrupts decidual hub speciﬁcation and eventually leads to pregnancy complications in DBA/2-mated CBA/J mice.

Bone marrow-derived progenitors become decidual cells and are essential for implantation and pregnancy maintenance

Project description:The pregnant decidua is infiltrated by many immune cells which are thought to originate in the bone marrow (BM) promoting pregnancy. In addition, BM-derived progenitor cells (BMDPCs) become non-hematopoietic endometrial cells. However, whether BMDPCs become non-immune decidual cells and their functional contribution to pregnancy were previously unknown. Here, we show that embryo implantation stimulates vast BMDPCs recruitment to decidua, where BMDPCs differentiate into non-hematopoietic stromal decidual cells. In addition, to determine the functional importance of BMDPCs to pregnancy, we used mice with endometrial stromal-specific defects precluding successful pregnancy. BM transplant (BMT) from wild-type (WT) into Hoxa11-/- mice, which lack decidualization, results in uterine transcriptional changes leading to stromal expansion, gland formation, and marked decidualization otherwise absent in Hoxa11-/- mice. By contrast, BMT from Hoxa11-/- into WT mice induces pregnancy loss. Importantly, in Hoxa11+/- mice, which have increased pregnancy losses, BMT from WT donors leads to normalized expression of numerous decidualization-related genes and rescue of pregnancy loss. Collectively, these findings reveal that BMDPCs have a novel non-hematopoietic physiologic contribution to decidual stroma, thereby playing indispensable roles in pregnancy establishment and maintenance.

Novel biomarkers for distributed stem cells: asymmetric self-renewal associated (ASRA) genes identification by combined cDNA micro-array orthogonal intersection and sparse feature analysis

Project description:Biomarkers unique for distributed stem cells (DSCs) have proven elusive. Previous searches for proteins expressed specifically in DSCs were hampered by difficulty obtaining pure DSCs and challenges to successfully mining complex molecular expression data. To identify novel candidates for DSC biomarkers, we combined a sparse feature selection method with combinatorial molecular expression data focused on asymmetric self-renewal, a defining DSC property. Our analyses revealed reduced expression of the histone H2A variant H2A.Z as a superior discriminator for asymmetric self-renewal, which proved to be a novel pattern-specific biomarker of DSCs.

Proteomic profiling of human decidual immune proteins during Toxoplasma gondii infection

Project description:A Toxoplasma gondii infection during pregnancy can result in spontaneous abortion, preterm labor, or congenital fetal defects. The decidual immune system plays a critical role in regulating the immune micro-environment and in the induction of immune tolerance. To better understand the factors that mediate the decidual immune response associated with the T. gondii infection, a large-scale study employing TMT proteomics was conducted to characterize the differential decidual immune proteomes from infected and uninfected human decidual immune cells samples. The decidual immune cells from 105 human voluntary abortion tissues were purified, and of the 5510 unique proteins identified, 181 proteins were found to be differentially abundant (>1.2-fold cutoff, P＜0.05) in the T. gondii-infected decidual immune cells. 11 proteins of 181 differentially expressed proteins associated with trophoblast invasion, placental development, intrauterine fetal growth, and immune tolerance were verified using a quantitative real-time polymerase chain reaction and western blotting. This systematic research identified a broad range of immune factors in human decidual immune cells, shedding a new insight into the decidual immune molecular mechanism for abnormal pregnancy outcomes associated with T. gondii infection.

The mammalian decidual cell evolved from a cellular stress response

Project description:Among animal species, cell types vary greatly in terms of number and kind. The broad range of number of cell types among species suggests that cell type origination is a significant source of evolutionary novelty. The molecular mechanisms giving rise to novel cell types, however, are poorly understood. Here we show that a novel cell type of eutherians mammals, the decidual stromal cell (DSC), evolved by rewiring an ancestral cellular stress response. We isolated the precursor cell type of DSCs, endometrial stromal fibroblasts (ESFs), from the opossum Monodelphis domestica. We show that, in opossum ESF, the majority of decidual core regulatory genes respond to decidualizing signals, but do not regulate decidual effector genes. Rather, in opossum ESF, decidual transcription factors function in apoptotic and oxidative stress response. We propose that the rewiring of cellular stress responses could be a general mechanism for the evolution of novel cell types.

Effect of ablation of trophoblast-derived signals on gene expression in the decidua of early pregnancy

Project description:Maternal-embryonic interactions play a critical role in successful pregnancy, with particular emphasis on the decidual-trophoblast interaction, which have been long recognized to exert a paracrine influence through the trophoblast cells on the progression of decidualization and the function of decidual cells. Despite this knowledge, the full extent of the embryo's impact on the decidua remains largely unexplored. To investigate the influence of embryonic signals on the maternal decidua, we utilized Prl3d1Cre/Cre mice mated with R26DTA/DTA mice, resulting in the generation of Prl3d1Cre/+, R26DTA/+ conceptus. In these conceptuses, the primary trophoblast giant cells (pTGCs) were selectively ablated by diphtheria toxin A (DTA). The pTGCs are the key embryonic cells that directly interact with the maternal decidua. Following the ablation of pTGCs, we observed impaired decidualization, as indicated by altered expression of genes related to decidualization or decidual function, such as Prl8a2, Wnt4, Bmp2, Alpl, and Hsd11b2, as well as a reduction in the interferon response in the decidua on day 6.5 of early pregnancy. Additionally, we found significant downregulation of numerous lipid-related biological effects in both deciduae on day 6.5 and day 8 of early pregnancy. These findings shed light on the complex interactions between the maternal and embryonic components during early pregnancy and underscore the importance of embryonic-derived influences on decidual lipid metabolism.

Endometrial extracellular vesicle decidualization

Project description:Proper decidualization is vital in preparation for a potential embryo receptivity, placentation, menstrual health and subsequent endometrial regeneration. Given the importance of extracellular vesicles (EVs) in intercellular communication, and recently in embryo implantation and indicators of menstrual cycle and fertility, we investigated their role during decidualization. Overall, this study provides an insight into distinct variation in sEV composition depending upon the level of decidualization of endometrial stromal cells, with the signaling potential to coordinate endometrial health ranging from embryo implantation, facilitating placentation and subsequent endometrial regeneration.

Transcriptomic profiling of canine decidualization and effects evoked by antigestagens on decidualized canine uterine stromal cells

Project description:Maternal-stroma derived decidual cells are the single population in the canine placenta expressing the nuclear progesterone (P4) receptor (PGR), rendering them crucial for the maintenance of canine pregnancy. Indeed, decreased circulating P4 levels or blockage of PGR function with antigestagens (e.g., aglepristone), culminates in the termination of canine pregnancy. As an in vitro model for canine decidualization, dog uterine stromal (DUS; Graubner et al., 2017) cells can be decidualized in vitro with cAMP. The antigestagens aglepristone and mifepristone ablate the expression of decidualization markers in DUS cells (e.g., PGR, PRLR, IGF1 or PTGES). In order to study the mechanisms involved in feto-maternal communication during pregnancy and induction of parturition, the goal of the present work was to assess transcriptional changes mediated by decidualization and antigestagens-induced effects in decidualized DUS cells. Decidualization led to the upregulation of 1841 differentially expressed genes (DEGs, P < 0.01, FDR < 0.01) involved in cellular proliferation and adhesion, mesenchymal-epithelial transition, extracellular matrix organization, and vaso- and immunomodulation. The 1475 DEGs downregulated after decidualization were mostly associated with apoptosis and cell migration. In decidualized DUS cells, aglepristone modulated 1400 DEGs and mifepristone 1558 DEGs. Interestingly, only around half of the identified DEGs were modulated uniquely by one of the antigestagens. In both situations, however, PGR-blockage was associated with an inversion of decidualization-induced effects. Comparison between antigestagens-mediated effects and transcriptional changes in the canine placenta at term allowed the identification of 191 DEGs associated with cell proliferation and adhesion, vascularization and immune activity. These findings emphasize the importance of P4/PGR signaling for decidual cells function.

Disrupted PGR-B and ESR1 signaling underlies defective decidualization linked to severe preeclampsia

Project description:In the present study, we aimed to discern the preconception decidual transcriptomic signature associated with in vivo defective decidualization in women who suffered sPE in a previous pregnancy. First, we performed a comparative global transcriptional profiling of endometrium from women who developed sPE in a previous pregnancy and from women who never have had sPE. Then, we selected those genes that were significantly deregulated 1.4-fold higher (FDR<0.05) and have an EntrezID code. As a result, we formulate a transcriptional signature associated with defective decidualization composed by 120 genes.
