Transcriptomic analysis of the interaction of choriocarcinoma spheroids with receptive vs. non-receptive endometrial epithelium cell lines: an in vitro model for human implantation

Project description:The aim of this study was to establish an in vitro model to investigate the initial stages of human implantation based on co-culture of a) immortalized cells representing the receptive (Ishikawa) or non-receptive (HEC-1-A) endometrial epithelium with b) spheroids of a trophoblastic cell line (JEG-3) modified to express green fluorescent protein. After co-culturing Ishikawa cells with trophoblast spheroids, 310 and 298 genes increased or decreased their expression compared to non-co-cultured Ishikawa control cells, respectively; only 9 genes (5 increased and 4 decreased) were differentially expressed in HEC-1-A upon co-culture with trophoblast spheroids. Compared to HEC-1-A, the trophoblast challenge to Ishikawa cells differentially regulated the expression of 495 genes. In summary, upon co-culture with the trophoblast spheroids, non-receptive epithelium is characterized by a muted transcriptional response which in turn fails to activate the full transcriptional response that trophoblast spheroids undergo when co-cultured with receptive epithelium.

Transcriptomic analysis of the interaction of choriocarcinoma spheroids with receptive vs. non-receptive endometrial epithelium cell lines: an in vitro model for human implantation.

Project description:PurposeSeveral in vitro systems have been reported to model human implantation; however, the molecular dynamics of the trophoblast vs. the epithelial substrate during attachment have not been described. We have established an in vitro model which allowed us to dissect the transcriptional responses of the trophoblast and the receptive vs. non-receptive epithelium after co-culture.MethodsWe established an in vitro system based on co-culture of (a) immortalized cells representing receptive (Ishikawa) or non-receptive (HEC-1-A) endometrial epithelium with (b) spheroids of a trophoblastic cell line (JEG-3) modified to express green fluorescent protein (GFP). After 48 h of co-culture, GFP+ (trophoblast cells) and GFP- cell fractions (receptive or non-receptive epithelial cells) were isolated by fluorescence-activated flow cytometry (FACS) and subjected to RNA-seq profiling and gene set enrichment analysis (GSEA).ResultsCompared to HEC-1-A, the trophoblast challenge to Ishikawa cells differentially regulated the expression of 495 genes, which mainly involved cell adhesion and extracellular matrix (ECM) molecules. GSEA revealed enrichment of pathways related to cell division, cell cycle regulation, and metabolism in the Ishikawa substrate. Comparing the gene expression profile of trophoblast spheroids revealed that 1877 and 323 genes were upregulated or downregulated when co-cultured on Ishikawa substrates (compared to HEC-1-A), respectively. Pathways favorable to development, including tissue remodeling, organogenesis, and angiogenesis, were enhanced in the trophoblast compartment after co-culture of spheroids with receptive epithelium. By contrast, the co-culture with less receptive epithelium enriched pathways mainly related to trophoblast cell proliferation and cell cycle regulation.ConclusionsEndometrial receptivity requires a transcriptional signature that determines the trophoblast response and drives attachment.

Podocalyxin governs the barrier function of human endometrial epithelium and critically regulates receptivity for embryo implantation

Project description:Embryo implantation is a key step in establishing pregnancy and a major limiting factor in IVF. Implantation requires the endometrium, the inner lining of the uterus, to transform from a non-receptive to a receptive state, to allow embryos to attach to the surface and enter into the tissue. However, the fundamental mechanisms governing receptivity are not well understood. Here we show that transmembrane protein podocalyxin is a major and clinically significant factor regulating human endometrial receptivity. Podocalyxin is expressed in all endometrial epithelial cells in the non-receptive state but is selectively down-regulated in the luminal epithelium at receptivity. We present evidence that podocalyxin critically governs the barrier function of the endometrial epithelium, likely as an intrinsic protective mechanism, rendering it non-receptive to an embryo. In addition, podocalyxin suppresses genes promoting receptivity (eg LIF, CSF1) but stimulates those inhibiting implantation (eg WNT7A, LEFTY2). Down-regulation of podocalyxin in the luminal epithelium, likely mediated by progesterone, selectively converts the endometrial surface to a more adhesive state that facilitates embryo attachment and penetration. Furthermore, inadequate down-regulation of podocalyxin in the endometrial luminal epithelium is associated with poorer implantation rates in IVF. We thus propose that podocalyxin promotes the barrier function of human endometrial epithelial cells and critically regulates receptivity for embryo implantation.

The Extracellular Vesicles Proteome of Endometrial Cells Simulating the Receptive Menstrual Phase Differs from That of Endometrial Cells Simulating the Non-Receptive Menstrual Phase

Project description:Successful embryo implantation into a receptive endometrium requires mutual endometrial-embryo communication. Recently, the function of extracellular vehicles (EVs) in cell-to-cell interaction in embryo-maternal interactions has been investigated. We explored isolated endometrial derived EVs, using RL95-2 cells as a model of a receptive endometrium, influenced by menstrual cycle hormones estrogen (E2; proliferative phase) progesterone (P4; secretory phase) and estrogen plus progesterone (E2P4; the receptive phase). EV sized particles were isolated by differential centrifugation and size exclusion chromatography. Nanoparticle tracking analysis was used to examine the different concentration and size of particles and EV proteomic analysis per-formed using shotgun label-free mass spectrometry. Our results showed that although endome-trial derived EVs were secreted in numbers independent of hormonal stimulation, EVs sizes were statistically modified by it. Proteomics analysis showed that hormone treatment changes affect the endometrial EVs proteome, with proteins enhanced within the EV E2P4 group shown to be in-volved in different processes such as embryo implantation, endometrial receptivity, and embryo development, supporting the concept of a communication system between the embryo and the maternal endometrium via EVs.

The endometrial trasccriptome transition accompanying acquisition of receptivity to embryo implantation in mice

Project description:Receptivity of the uterus is essential for embryo implantation and progression of pregnancy. Acquisition of receptivity involves major molecular and cellular changes in the endometrial lining of the uterus from its non-receptive state at ovulation, to its receptive state four days later. The precise molecular mechanisms underlying this transition remain to be fully characterized. Here, we aimed to generate a comprehensive profile of the uterine transcriptome in the peri-ovulatory and peri-implantation states, and to define the differences between them, in the mouse. High throughput RNA-sequencing was utilized to identify genes and pathways expressed in the endometrium of C57Bl/6 female mice on day 3.5 post-coitum after mating with BALB/c males, compared to the endometrium of unmated estrous females (n=3-4 biological replicates). RNA-sequencing and analysis using Ingenuity Pathway Analysis software revealed that, compared to the endometrium at estrus, 388 genes were differentially expressed in the endometrium on day 3.5 post-coitum (FDR ≤ 0.05). Several upstream regulators are implicated in the transition to receptivity including several cytokines, steroid hormones, prostaglandin E2, and vascular endothelial growth factor A. The transcriptional changes indicate substantial changes in the uterine immune and vascular systems during the pre-implantation phase, with the functional terms Angiogenesis, Chemotaxis, and Lymphangiogenesis predominating. This analysis confirms that the transcriptome of a receptive uterus is vastly different to the non-receptive uterus and identifies several genes and regulatory pathways not previously associated with implantation. This dataset will serve as a valuable tool and resource for future research on the molecular mechanisms of uterine receptivity.

Endometrial methylome of healthy women during the transition from pre-receptive to receptive phase

Project description:The inner uterine lining (endometrium) has been shown to have a distinct methylation pattern that changes throughout the menstrual cycle. However, not much is known about how the endometrial methylome affects endometrial receptivity to implanting embryo in the second half of the menstrual cycle. The aim of the present study was to use genome-wide technologies and a paired study design to characterize the endometrial methylome in pre-receptive and receptive endometrium sampled from 17 healthy women within the same menstrual cycle.

Natural cycle frozen embryo transfer is superior to artificial cycle in women with recurrent implantation failure: endometrial transcriptome study

Project description:Transcriptome profile of receptive phase endometrium among infertile women with recurrent implantation failure (RIF) in two different endometrial preparation protocols for FET was analyzed: natural cycle (NC-FET) vs. artificial cycle (AC-FET). Fifteen endometrial biopsy samples were obtained: women with unexplained RIF (n = 5) in natural cycles for FET (NC-FET), women with unexplained RIF undergoing artificial endometrial preparation (n = 5) for FET (AC-FET), and healthy women (n = 5) with proven fertility in natural cycles (NC-FC) (Control group). All endometrial biopsies were obtained during the mid-secretory phase, at the time of ‘window of implantation’.

Analyses of circRNA profiling during the development from pre-receptive to receptive phases in goat endometrium

Project description:In the present study, RNA-seq technique was used to compare the expression profiles of circRNAs from goat endometrium samples at gestational day 5 (pre-receptive endometrium, PE) and day 15 (receptive endometrium, RE). A total of 21,813 circRNAs were identified in goat endometrium, of which only 31.22% (6,810) circRNAs were co-expressed at both stages, and 5,925 circRNAs were identified specifically in RE and 9,078 in PE, suggesting high stage specificity in the circRNAs in dairy goats. Further analysis found that there were 334 DECs (differentially expressed circRNAs) in RE compared to PE (P< 0.05), and circRNA8077 was up-regulated with the highest FPKM value in RE. It was noteworthy that half of the up-regulated circRNAs with top 10 highest FPKM value in RE were come from CRIM1. Moreover, GO and KEGG analysis of the hgDEGs (hosting genes of DECs) revealed some circRNAs, genes and pathways that may involve in the formation of the receptive endometrium in dairy goats. In a word, our data provided an endometrium circRNA expression atlas related to the biology of the goat receptive endometrium during embryo implantation, and the results suggested that a subset of circRNAs might involve in the processes of the formation and development of endometrial receptivity.
