Single-nucleus RNA sequencing of human trophoblast organoids and endometrial organoids co-culture model

ABSTRACT: To model the maternal–fetal interface, we co-cultured rotation-derived human trophoblast organoids (hTOr) with human endometrial organoids (hEMO). Here, we performed single-nucleus RNA sequencing of hEMO mono-culture, hTOr mono-culture, and their co-culture to dissect the transcriptomic landscape of this interaction. Our analysis reveals that hTOr-derived signals drive a metabolic and secretory activation in the endometrial epithelium. We identified a unique 'Activated' hEMO population emerging specifically upon co-culture, distinct from the LGR5+ homeostatic state. This transition was characterized by a robust upregulation of oxidative phosphorylation and glycolysis, concurrent with sustained proliferation, demonstrating that the trophoblast actively reprograms the endometrium into a hyper-metabolic state.

Derivation of endometrial gland organoids from term placenta

Project description:A limitation of current methods for the generation of endometrial gland organoids is their reliance on decidua isolated from endometrial biopsies or elective abortion. Here we report the establishment of endometrial gland organoids from decidua isolated from term placental membranes. These organoids express typical markers of glandular epithelia such as E-cadherin, Laminin and Cytokeratin 7, and can be propagated in cell culture through multiple passages. Additionally, we identified potential survival factors for the co-culture of organoids and endometrial stromal fibroblasts. These modifications facilitate the generation of patient-specific endometrial gland organoids with known pregnancy outcomes.

RNA-seq of Pluripotent Stem Cell-Derived Endometrial Stromal Fibroblasts in Monolayer Differentiation and in Co-culture with Endometrial Epithelial Organoids

Project description:H9 Pluripotent Stem Cells (PSC) were differentiated to Endometrial Stromal Fibroblasts (PSC-ESF) in monolayer over the course of 12 days. Gene expression was measured at day 0, day 4, day 8, and day 12 of differentiation. At day 12, PSC-ESF were dissociated from monolayer culture for co-culture with endometrial epithelial organoids established from term decidua. Gene expression was also measured after 26 days in co-culture (Cycle 1, vehicle or cAMP/progesterone/estradiol) and after 52 days in co-culture (Cycle 2, vehicle or cAMP/progesterone/estradiol)

Bulk RNA-seq of human trophoblast organoids under four culture conditions

Project description:Bulk RNA-seq was performed to compare transcriptomic profiles of human trophoblast stem cell (hTSC)-derived organoids cultured under four conditions: rotation, floating (static suspension), shaking (horizontal agitation), and Matrigel embedding. Two independent hTSC lines (B31 and CT27) were used. Total RNA was extracted, and strand-specific poly(A)-selected libraries were sequenced on Illumina NovaSeq X Plus (PE150).

scRNA-seq and snucRNA-seq of human primary trophoblast organoids (PTO) and trophoblast stem cells (TSCs) differentiation into extravillous trophoblast organoids (EVTs)

Project description:This study aims to compare in vivo human trophoblast differentiation into EVTs to different in vitro trophoblast organoids using single-cell and single-nuclei RNA sequencing. The study includes two type of systems: human primary trophoblast organoids (PTO) and trophoblast stem cells (TSCs). Trophoblast stem cell (TSC) lines BTS5 and BTS11 derived by Okae and colleagues were grown as described previously (Okae et al. 2018) and together with EVT media. Primary trophoblast organoids (PTO) were grown and differentiated into EVT as previously described by Turco & Sheridan (Turco et al 2018; Sheridan et al 2020). This study shows that the main regulatory programs mediating EVT invasion in vivo are preserved in in vitro models of EVT differentiation from primary trophoblast organoids and trophoblast stem cells.

Endometrial assembloid model reveals endometrial adenogenesis regulation by estradiol-driven WNT7B expression [scRNA-seq]

Project description:To establish an in vitro endometrial co-culture model, endometrial organoid was co-cultured with endometrial stromal cells in a 3D hydrogel matrix. During this co-culture process, tubular gland development was identified from endometrial organoids, which showed the molecular, morphological and functional properties of human endometrial glands. To further characterize the genetic drive for this phenomenon, we conducted single-cell RNA sequencing analysis at day 1 and day 9 after co-culture.

Integrated microRNA and secretome analysis of human endometrial organoid reveal the miR-3194-5p/Aquaporin/S100A9 module in regulating trophoblast functions

Project description:Successful placentation requires delicate communication between endometrium and trophoblasts. The invasion and integration of trophoblasts into the endometrium during early pregnancy is crucial to placentation. Dysregulation of these functions is associated with various pregnancy complications such as miscarriage and preeclampsia. The endometrial microenvironment exerts an important influence on trophoblast cell functions. We hypothesized that the hormonal environment regulates the miRNA profile and secretome of the human endometrial gland, which subsequently modulates trophoblast functions during early pregnancy. By establishing the first secretome profiles and miRNA atlas of these endometrial organoids to the hormonal changes followed by trophoblast functional assays, we demonstrated that sex steroid hormones modulate aquaporins (AQP)1/9 and S100A9 secretions through miR-3194 activation in endometrial epithelial cells, which in turn enhanced trophoblast migration and invasion during early pregnancy.

scRNA-seq of patient-derived PDAC organoids and matched CAFs

Project description:We established direct three-dimensional (3D) co-cultures of primary PDAC organoids and patient-matched CAFs. Single-cell RNA sequencing was performed for three organoid/CAF pairs in mono- and co-culture to uncover transcriptional changes induced by tumor-stroma interaction. Single-cell RNA sequencing data evidenced induction of a pro-inflammatory phenotype in CAFs in co-cultures. Organoids showed increased expression of genes associated with epithelial-to-mesenchymal transition (EMT) in co-cultures and several potential receptor-ligand interactions related to EMT were identified, supporting a key role of CAF-driven induction of EMT in PDAC chemoresistance.

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.
