Global transcriptional profiling confirmed failed decidualization of human Endometrial Stromal Cells (hESCs) obtained from non-pregnant women with a previous pregnancy complicated by severe preeclampsia (sPE).

ABSTRACT: The data presented here suggested that sPE is associated with impaired decidualization. Initial experiments involved an in vitro approach. hESCs were isolated from patients who developed sPE in a previous pregnancy or control women who had normal obstetric outcomes. Function was tested by comparing the ability of hESCs in the two groups to decidualize in culture. By morphological criteria and marker expression (PRL and IGFBP1), the cells in the formerly sPE group were decidualization resistant, which was confirmed by microarray analyses showing that they were transcriptionally inert.

Mapping Decidualization Resistance in Former Severe Preeclampsia Patients at Multi-Omic Levels

Project description:Endometrial decidualization resistance (DR) is implicated in various gynaecological and obstetric conditions. Employing a multi-omic strategy, we unraveled the cellular and molecular characteristics of DR in patients that have suffered severe preeclampsia (sPE). Morphological analysis unveiled significant glandular anatomical abnormalities, confirmed histologically. Single-cell RNA sequencing (scRNA-seq) of endometrial samples from sPE cases (n=11) and controls (n=12) revealed sPE-associated shifts in cell composition, manifesting as a stromal mosaic state characterized by proliferative stromal cells (MMP11, SFRP1+) alongside IGFBP1+ decidualized cells, with concurrent epithelial mosaicism and a dearth of epithelial-stromal transition associated with decidualization. Cell-cell communication network mapping underscored aberrant crosstalk among specific cell types, implicating crucial pathways such as endoglin and WNT. Spatial transcriptomics in a replication cohort validated DR-associated features. Laser capture microdissection/mass spectrometry in a second replication cohort corroborated several scRNA-seq findings, notably the absence of stromal to epithelial transition at a pathway level, indicating disrupted response to steroid hormones, particularly estrogens. These insights shed light on potential molecular mechanisms underpinning DR pathogenesis in the context of sPE.

Endometrial gland impacts on stromal cell decidualization

Project description:Uterine glands and, by inference, their secretions impact uterine receptivity, blastocyst implantation, stromal cell decidualization, and placental development. Changes in gland function across the menstrual cycle are impacted by steroid hormones, estrogen and progesterone, as well as stroma-derived factors. Using an endometrial epithelial organoid (EEO) system, transcriptome and proteome analyses identified distinct responses of the EEO to steroid hormones and prostaglandin E2 (PGE2). Notably, steroid hormones and PGE2 modulated the basolateral secretion of EEO proteins, where cystatin C (CST3) was significantly increased by progesterone and PGE2. CST3 treatment of decidualizing stromal cells significantly decreased the decidualization markers PRL and IGFBP1. The attenuation of stromal cell decidualization via CST3 suggests a role for uterine gland-derived proteins in controlling the extent of decidualization. These findings provide evidence that uterine gland-derived factors directly impact stromal cell decidualization, which has strong implications for better understanding pregnancy establishment and female fertility in humans.

The role of Prokineticin 2 in endometrial decidualization

Project description:Recurrent implantation failure(RIF) is an urgent problem to be solved in reproduction.Currently, endometrium decidualization damage is considered as one of the important causes, but the mechanism is still unclear. Prokineticin 2(PK2) is a newly discovered secreted protein with multiple biological functions, and its role in the endometrium is unknown.Our previous study showed that PK2 was significantly increased in RIF patients, but endometrial decidualization markers PRL and IGFBP1 were lower compared with the control group. We performed transcriptome sequencing, we found there were significant differences between the PK2 overexpression group and the control group. Differential genes mainly involved in decidualization process including adhesion, immunity, chemotaxis, ect.

Defective Decidualization During and After Severe Preeclampsia Reveals a Possible Maternal Contribution to the Etiology

Project description:In preeclampsia (PE), cytotrophoblast (CTB) invasion of the uterus and spiral arteries is often shallow. Thus, the placenta’s role has been a focus. We hypothesized that decidual defects are an important determinant of the placental phenotype. We isolated (human) endometrial stromal cells (hESCs) from non-pregnant donors with a prior pregnancy that was complicated by severe PE (sPE). Versus controls, they failed to decidualize as demonstrated by morphological criteria and the analysis of stage-specific antigens. These results were bolstered by showing that they were transcriptionally inert. Additionally, we used laser microdissection to isolate the decidua from tissue sections of the maternal-fetal interface. Transcriptional profiling revealed sPE-associated defects in gene expression. Also, decidual cells from sPE patients, which de-differentiated in vitro, failed to re-decidualize in culture. Immediately following isolation they released factors that inhibited CTB invasion, linking a possible cause to a known effect. These data suggested that failed decidualization is an important contributor to down regulated CTB invasion in sPE. Diagnosis of this defect prior to pregnancy would enable therapies that are designed to improve decidualization, a novel strategy for prevention.

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.

Expression data from non-decidualized and decidualized endometrial stromal cell (ESCs) with or without WT1 knockdown

Project description:Wilms tumor 1 (WT1) regulates the expression of insulin-like growth factor-binding protein-1 (IGFBP-1) and prolactin (PRL) during decidualization of human endometrial stromal cells (ESCs). However, other roles of WT1 in decidualization have not been fully clarified. We used microarrays to identify the physiological roles of WT1 in the regulation of cellular functions of human ESCs during decidualization.

Transcriptional profiles of decidualized cultured WT vs NELF-B cKO Uterine stromal cells

Project description:Pausing of RNA polymerase II (Pol II) during early transcription, mediated by the negative elongation factor (NELF) complex, allows cells to coordinate and appropriately respond to signals by modulating the rate of transcriptional pause release. Promoter proximal enrichment of Pol II occurs at uterine genes relevant to reproductive biology; thus, we hypothesized that pausing might impact endometrial response by coordinating hormonal signals involved in establishing and maintaining pregnancy.We deleted the NELF-B subunit in themouse uterus using PgrCre (NELF-B UtcKO).Resulting females were infertile.Uterine response to the initial decidual stimulus of NELF-B UtcKOwas similar to that of control mice; however, subsequent full decidual response was not observed. Cultured NELF-B UtcKO stromal cells exhibited perturbances in extracellular matrix components and also expressed elevated levels of the decidual prolactin Prl8a2, as well as altered levels of transcripts encoding enzymes involved in prostaglandin synthesis and metabolism. Because endometrial stromal cell decidualization is also critical to human reproductive health and fertility, we used small interfering to suppressNELF-B or NELF-E subunits in cultured human endometrial stromal cells, which inhibited decidualization, as reflected by the impaired induction of decidual markers PRL and IGFBP1. Overall, our study indicatesNELF-mediated pausing is essential to coordinate endometrial responses and that disruption impairs uterine decidual development during pregnancy.

The coregulator, repressor of Estrogen Receptor Activity (REA), is a crucial regulator of the timing and magnitude of uterine decidualization.

Project description:Our findings establish a key role for the coregulator, Repressor of Estrogen receptor Activity (REA), in controlling the timing and magnitude of decidualization in human endometrial stromal cells in vitro and in the mouse uterus in vivo, and suggest that REA functions to synchronize uterine differentiation with concurrent embryo development, which is essential for optimal implantation and fertility. The findings highlight that REA physiologically restrains endometrial stromal cell decidualization, controlling the timing and magnitude of decidualization to enable proper synchronization of uterine differentiation with concurrent embryo development that is essential for implantation and optimal fertility. Human endometrial stromal cells (hESCs) were isolated from biopsies taken from the early proliferative stage endometrium of regularly cycling women on no hormonal medications. Cells were cultured in DMEM/F-12 mediumcontaining 5% charcoal stripped fetal bovine serum. To induce in vitro decidualization, hESCs were treated with a hormone cocktail containing 10 nM estradiol (E2), 1 Î¼M progesterone (P4) and 0.5 uM 8-bromo-cAMP for up to 10 days, and media were changed every 48 h. For siRNA experiments, hESCs were transfected with REA siRNA or GL3 luciferase control siRNA following the Silent-Fect kit protocol. After 48 h of transfection, hESCs were exposed to the hormone cocktail for 24 hours or 96 hours of differentiation. key words; siRNA knock-down, hormone cocktail treatment

Expression data from ATRA-treated endometrial stromal cells

Project description:Decidualization is critical for the embryonic implantation and successful pregnancy. ATRA can suppress in-vitro decidualization of human endometrial stromal cells (hESCs) induced by MPA and estrogen treatment. However, the mechanism by which RA suppressed estrogen and progesterone induced decidualization of mESCs is not clear. We used microarrays to investigate the mechanism by which all-trans RA (ATRA) regulates the decidualization of endometrial stroma cells (mESCs). mESCs were isolated at day 4 of pseudopregnancy and cultured with administration of E2 and P4 in the presence or absence of ATRA for 72h.
