Expression data of human trophectoderm cells

ABSTRACT: The implantation process begins with attachment of the trophectoderm (TE) of the blastocyst to the maternal endometrial epithelium. Herein we have investigated the transcriptome of mural TE cells from 13 human blastocysts and compared these with those of human embryonic stem cell (hESC)-derived-TE (hESCtroph). The transcriptomes of hESFtroph at days 8, 10, and 12 had the greatest consistency with TE. Among genes coding for secreted proteins of the TE of human blastocysts and of hESCtroph are several molecules known to be involved in the implantation process as well as novel ones, such as CXCL12, HBEGF, inhibin A, DKK3, Wnt 5A, follistatin. The similarities between the two lineages underscore some of the known mechanisms and offer discovery of new mechanisms and players in the process of the very early stages of human implantation. We propose that the hESCtroph is a viable functional model of human trophoblasts to study trophoblast-endometrial interactions. Furthermore, the data derived herein offer the promise of novel diagnostics and therapeutics aimed at practical challenges in human infertility and pregnancy disorders associated with abnormal embryonic implantation. Transcriptome analyses suggest human embryonic stem cell-derived-trophoblast as a viable functional model of human trophoblast to study trophoblast-endometrial interactions.

Transcriptome analyses suggest human embryonic stem cell-derived-trophoblast as a viable functional model of human trophoblast to study trophoblast-endometrial interactions. Five pools of trophectoderm cells were subjected to RNA isolation and microarray. The resulting data were compared to the transcriptomes of H7 human embryonic stem cells differentiated to the trophoblast lineage after 0, 2, 4, 6, 8, 10 and 12 days of induction with BMP-4. This submission represents the trophectoderm cells from blastocysts.

Gene expression analysis of an endometrial cell line

Project description:This group is studying the role of glycoproteins in embryo implantation and development of the maternal-fetal interface. The Aplin lab is developing an embryo implantation model in which blastocysts attach to human endometrial cells. The project aims to investigate the molecular interactions mediating attachment and subsequent events including trophoblast invasion and displacement of maternal cells. In the present phase of the project, the lab is using the Ishikawa (human endometrial) cell line with mouse embryos.

Transcription profiling of human endometrial stromal cells treated with human trophoblasts vs. control, sampled at multiple time points to investigate stromal cell response to paracrine signals from the trophoblast

Project description:During the invasive phase of implantation, trophoblasts and maternal decidual stromal cells secrete products that regulate trophoblast differentiation and migration into the maternal endometrium. Paracrine interactions between the extravillous trophoblast and the maternal decidua are important for successful embryonic implantation, including establishing the placental vasculature, anchoring the placenta to the uterine wall, and promoting immuno-acceptance of the fetal allograph. Global cross-talk between the trophoblast and the decidua has not been elucidated to date, and the current study used a functional genomics approach to investigate these paracrine interactions. Human endometrial stromal cells were decidualized with progesterone and were further treated with conditioned media (CM) from human trophoblasts (TCM) or, as a control, with conditioned media (CCM) from non-decidualized stromal cells for 0, 3 and 12 hr. Total RNA was isolated and processed for analysis on whole genome, high density oligonucleotide arrays, containing 54,600 genes. Our data demonstrate a significant induction of pro-inflammatory cytokines and chemokines, as well as angiogenic/static factors in decidualized endometrial stromal cells in response to trophoblast-secreted products. The data suggest that the trophoblast acts to alter the local immune environment of the decidua to facilitate the process of implantation and assure an enriched cytokine/chemokine environment, while limiting mitotic activity of the stromal cells during the invasive phase of implantation.

Preimplantation Factor Effect on Endometrial and Decidual Cells

Project description:Embryos secrete preimplantation factor (PIF), a peptide present in maternal circulation during viable pregnancy. We compared downstream synthetic PIF effect on gene expression in non-pregnant Human Endometrial Stromal Cell (HESC) and First Trimester Decidual cell (FTDC) culture to mimic the maternal intrauterine environment during embryo implantation and trophoblast invasion. Cells were cultured in triplicate with and without synthetic PIF for 24 hours. Cultured cells were then pooled for chip analysis. Altered gene expression relative to controls was assessed by Affymetrix microarray

Establishment of trophoblast stem cells under defined culture conditions in mice

Project description:The inner cell mass (ICM) and trophoblast cell lineages duet early embryonic development in mammals. After implantation, the ICM forms the embryo proper as well as some extraembryonic tissues, whereas the trophoectoderm (TE) exclusively forms the fetal portion of the placenta and the trophoblast giant cells. Although embryonic stem (ES) cells can be derived from ICM in cultures of mouse blastocysts in the presence of LIF and/or combinations of small-molecule chemical compounds, and the undifferentiated pluripotent state can be stably maintained without use of serum and feeder cells, defined culture conditions for derivation and maintenance of undifferentiated trophoblast stem (TS) cells have not been established. Here, we report that addition of FGF2, activin A, XAV939, and Y27632 are necessary and sufficient for derivation of TS cells from both of E3.5 blastocysts and E6.5 early postimplantation extraembryonic ectoderm. Moreover, the undifferentiated TS cell state can be stably maintained in chemically defined culture conditions. Cells derived in this manner expressed TS cell marker genes, including Eomes, Elf5, Cdx2, Klf5, Cdh1, Esrrb, Sox2, and Tcfap2c; differentiated into all trophoblast subtypes (trophoblast giant cells, spongiotrophoblast, and labyrinthine trophoblast) in vitro; and exclusively contributed to trophoblast lineages in chimeric animals. This delineation of minimal requirements for derivation and self-renewal provides a defined platform for precise description and dissection of the molecular state of TS cells. Total RNA was purified by using RNeasy Mini kit (QIAGEN). Microarray targets from 200 ng total RNA were synthesized and labelled using the Low RNA Input Linear Amp Kit (Agilent) and hybridized to Mouse 4x44K Ver.2.0 arrays. Arrays were scanned on an Agilent Technologies Microarray scanner and signal intensities were calculated in Agilent Feature Extraction 10.7.3.1 software.

3D-cultured blastoids model human embryogenesis from pre-implantation to early gastrulation stages

Project description:Naïve human pluripotent stem cells have the remarkable ability to self-organize into blastocyst-like structures (“blastoids”) that model lineage segregation in the pre-implantation embryo. However, the extent to which blastoids can recapitulate defining features of human post-implantation development remains unexplored. Here, we report that blastoids cultured on thick 3D extracellular matrices capture hallmarks of early post-implantation development, including epiblast lumenogenesis, rapid expansion and diversification of trophoblast lineages, and robust invasion of extravillous trophoblast cells by day 14. Extended blastoid culture results in the localized activation of primitive streak marker TBXT and the emergence of embryonic germ layers by day 21. We also show that modulation of WNT signaling alters the balance between epiblast and trophoblast fates in post-implantation blastoids. This work demonstrates that 3D-cultured blastoids offer a continuous and integrated in vitro model system of human embryonic and extraembryonic development from pre-implantation to early gastrulation stages.

SECRETORY PROTEOMIC RESPONSES OF ENDOMETRIAL EPITHELIAL CELLS TO TROPHOBLAST DERIVED EXTRACELLULAR VESICLES

Project description:Synchronized cross talk between embryo and endometrium during pre-implantation period is critical for establishment of pregnancy. Extracellular vesicels(EVs) of both embryo and endometrial origin are known to be integral in regulating embryo maternal communication during this time. However, exact molecular signalling pathways or factors that regulate the embryo endometrial communication during pre-conception period remains elusive. Here in this study extracellular vesicles from trophoblast cells were shown to modulate endometrial epithelial cell secretome in favour of embryo implantation and embryo development.
