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.

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.

Project description:In this project we evaluated the proteomic profiling with TGF-β stimuli at 24h in a CRISPR-Cas9 model for ALMS1 gene in hTERT-BJ-5ta cells. Proteomic results showed a majority inhibition of downstream regulated pathways by the TGF-β, associating the protein coding genes (PCG) with processes like TGF- β matrix regulation, epithelial mesenchymal transition (EMT), PI3K/AKT or P53. In conclusion, seems that the depletion of ALMS1 could be inhibiting the signals transduction through the TGF -β and the routes regulated downstream.

Project description:There are three well-established mouse models of decidualization: natural pregnancy decidualization (NPD), artificial decidualization (AD) and in vitro decidualization (IVD). In the present study, we analyzed global gene expression changes by using RNA-seq.

Project description:Analysis of differences in gene expression in the mouse uterus during decidualization in the presence and absence of a conceptus. A deciduomal model previously shown to better mimick natural decidualization was used. The results reveal some, but very few, genes that are differentially expressed, which is unlike previous reports using other deciduomal models shown previously to not mimick natural decidualization. Total RNA obtained from isolated uterine segment tissue undergoing decidualization from pregnant or pseudopregnant mice. Three replicates per condition.

Project description:Decidualization of human endometrial stromal cells (hESCs), a critical process for embryo implantation and successful pregnancy, begins during the secretory phase of the menstrual cycle. We evaluated 25 established in vitro decidualization markers in hESCs using in vivo single-cell transcriptomic data. Most markers, including PRL and IGFBP1, did not reliably distinguish between proliferative and secretory phase hESCs, nor between decidualized and non-decidualized hESCs. Only 8 genes (STAT3, CEBPB, WNT4, IL-15, TIMP3, HAND2, FOXO1 and MMP19) showed differential expression between the menstrual phase and decidualization status in vivo. We hypothesized that the difference between in vitro and in vivo marker expression might result from the absence of endometrial glands in the in vitro decidualization model. While endometrial glands are known to secrete factors critical for uterine receptivity, their specific role in decidualization is not well understood. To investigate this, we examined the influence of the glandular secretome on ESC decidualization using an in vitro co-culture model of human endometrial organoids (hEOs) and hESCs. Decidualization was induced in hESCs, and the effects of hEO co-culture or exposure to hEO secretome were assessed by morphological analysis, molecular marker expression, and transcriptomic profiling. Unexpectedly, both hEO co-culture and exposure to the hEO secretome significantly reduce the up-regulation of canonical decidualization markers and the mesenchymal-epithelial transition typically induced during hESC decidualization. Transcriptomic analysis further revealed downregulation of decidualization regulators, CEBPA and EDN1, in ESCs exposed to the hEO secretome compared to decidualized controls. These findings were corroborated in an estradiol-stimulated mouse model, where increased endometrial gland formation correlated with reduced decidualization and lower expression of CEBPA and EDN1. Collectively, our results reveal a previously unrecognized homeostatic role for the endometrial gland secretome in regulating ESC decidualization. These insights highlight the limitations of current in vitro decidualization models and underscore the importance of glandular-stromal interactions in endometrial function and reproductive health.

Project description:It is hypothesized that impaired endometrial decidualization contributes to decreased fertility in endometriosis patients. To identify the molecular defects that underpin defective decidualization in endometriosis, we subjected endometrial stromal cells from healthy individuals or with endometriosis to time course in vitro decidualization with estradiol, progesterone, and 8-bromo-cyclic-AMP (EPC) for 2, 4, 6, or 8 days. Transcriptomic profiling identified novel differences in key pathways between normal and endometriosis, including defective bone morphogenetic protein (BMP) signaling (ID1, ID2, ID3, BMP6), altered iron transport (SLC40A1, TFRC), endometrial stem cell markers (CD44, SUSD2), and retinoid signaling pathways (RORB, ALDH1L1, RARA). Genome-wide binding analyses identified an altered genomic distribution of SMAD4 in decidualized stromal cells from endometriosis patients relative to normal individuals, with an overrepresentation of gene ontologies related to signaling by transforming growth factor β (TGFβ), neurotrophic tyrosine kinase receptors (NTRK), and nerve growth factor (NGF)-stimulated transcription. We found that direct SMAD1/5/4 target genes control FOXO, PI3K/AKT, and progesterone-mediated signaling in decidualizing cells and that BMP2 supplementation of patient-derived assembloids from endometriosis patients restored decidualization. In summary, transcriptomic and genomic profiling of patient-derived endometrial cells and assembloids identified that restoring BMP/SMAD1/5/4 signaling is crucial for engaging a robust decidualization program in women with endometriosis.
