Specification of HiPS to in vivo placental cell types

ABSTRACT: Here we identify conditions that efficiently drive specification of primed induced pluripotent stem cells to trophectoderm, named Trophoblast Stem Cell (TS). iPS-derived-TS cells share transcriptional, morphological and functional characteristics with human ex vivo cytotrophoblasts including transcriptional activation of human endogenous retroviruses, expression of COVID-19 associated host factors and the ability to generate multinucleated syncytiotrophoblasts with a large fusion index. At high densities in 5% O2, iPS-derived-TS cells form villi-like structures and express extravillous and syncytiotrophoblast proteins HCG-β, HLA-G. To define the molecular changes associated with specification, we compare temporal single cell RNAseq analysis under three separate conditions: 1) BMP4, 2) BMP4 and inhibition of Wnt, 3) Trophoblast Stem cell condition (TS) activation of EGF and Wnt, inhibition of TGFbeta, HDAC and ROCK signaling.

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.

Fgf and Esrrb integrate epigenetic and transcriptional networks that regulate self-renewal of Trophoblast Stem Cells

Project description:Derivation and maintenance of TS cells depends on the presence of Fgf signalling. Numerous gene knock-out experiments identified the mitogen activated kinase Mek/Erk branch of the Fgf signalling pathway as predominantly active in both TS cells and extraembryonic ectoderm. Therefore, we tested changes in expression of the key TS cell transcription factors (TFs) upon Mek/Erk inhibition using the Mek inhibitor PD0325901 (“PD03”). To obtain an unbiased genome-wide coverage of the immediate-early response genes of Mek inhibition in TS cells, we performed RNA-seq analysis after 3h and 24h of PD03 treatment. Notably, of the known TS cell TFs, this analysis confirmed Esrrb as the earliest, most rapidly silenced gene upon PD03 treatment. In order to gain first insights into which genes may be primary targets of Esrrb, we treated TS cells with the synthetic nonsteroidal estrogen diethylstilbestrol (DES), an estrogen-related receptor (Err) antagonist and also performed RNA-seq upon short (24h) and prolonged (4d) DES treatment. Finally, to obtain a comprehensive global overview of the binding sites of Esrrb in TS cells, and of its interaction with Lsd1 and Nr0b1 (Dax1), we performed chromatin immunoprecipitation (ChIP)-seq experiments on these factors.

Enzymatic Methyl-seq (EM-seq) of doxycycline induced tumor and residual mouse primary mammary epithelial cells grown in 3D cell cultures against non-induced controls

Project description:This experiment investigates the genome wide DNA methylation landscape of residual breast cancer cells. Primary mammary epithelial cells taken from female mice with doxycycline-inducible hMyc- and Neu/Her2-oncogenes were grown in 3D organoid cultures. Upon the addition of doxycycline (200ng/mL) to the medium the expression of the oncogenes gets activated and the cells start uncontrolled proliferation resembling tumor growth. Tumor samples were taken after 5 days of oncogene induction. Subsequently, doxycycline was removed from the medium, which silences oncogene expression and results in rapid tumor regression. Residual samples reminiscent to the non-induced (normal) structures were taken after 7 days of de-induction (12 days overall). Non-induced structures were grown and sampled in parallel to the residual structures.

Single cell RNA sequencing of stem cell-derived retinal ganglion cells

Project description:We used human embryonic stem cell-derived retinal ganglion cells (RGCs) to characterize the transcriptome of 1,174 cells at the single cell level. The human embryonic stem cell line BRN3B-mCherry A81-H7 was differentiated to RGCs using a guided differentiation approach. Cells were harvested at day 36 and incubated with THY1 antibody (Miltenyi) before undergoing FACS. THY1 positive and THY1 negative cells were subsequently prepared for single cell RNA sequencing. Single cell suspensions were loaded onto 10X Genomics Single Cell 3' Chips along with the reverse transcription master mix as per the manufacturer's protocol for the Chromium Single Cell 3' v2 Library (10X Genomics; PN-120233), to generate single cell gel beads in emulsion. Libraries were then sequenced on an Illumina HiSeq 2500.

Essential gene screening identifies the Bromodomain-Containing Protein BRPF1 as a new therapeutic target for endocrine therapy-resistant breast cancer - organoids

Project description:Exploring epigenetic gene essentiality identifying key regulators of cell survival represents a promising way to exploit new targets to overcome resistance to current pharmacological regimens. In breast cancer (BC), endocrine therapy (ET) resistance arises from aberrant Estrogen Receptor alpha (ERα) signaling and targeting cancer cell vulnerability within the ERα pathway represents a rationale for development of effective new drugs against this disease. By combining bioinformatics analysis of genome-wide ‘drop-out’ screenings and siRNA-mediated gene knock-down (kd) we identified a set of essential genes that includes, as the most effective, the bromodomain containing protein BRPF1. BRPF1 belongs to a family of epigenetic readers acting as chromatin remodelers to control gene transcription. To gather mechanistic insight into the role of this epienzyme in BC, we applied chromatin and transcriptome profiling, gene ablation and specific pharmacological inhibition followed by cellular and functional assays. Experimental evidences indicate that BRPF1 associates with ERa in MCF-7 cells chromatin and its blockade inhibits cell cycle progression, reduces cell proliferation and mediates transcriptome changes through modulation of chromatin accessibility. This results in a widespread inhibition of ER-dependent hormonal signaling obtained by ERa gene silencing in AE-sensitive and -resistant BC cells and pre-clinical patient-derived models (PDO). The characterization of functional interplays between ERα and BRPF1 revealed a new master regulator of BC survival, providing a rationale for a BRPF1 targeted cancer diagnosis and highlighting a new therapeutic vulnerability for the treatment of these aggressive tumors.

Metabolic enhancement of developmental pausing (embryos)

Project description:Embryonic stem (ES) cells and embryos reversibly pause via chemical mTOR inhibition. In this study, we investigate the tissue-specific response to mTORi-induced pausing in ES and trophoblast stem (TS) cells. To resolve the sequential rewiring of the proteome, we conducted a time-series proteomics experiment at 1, 3, 6, 12, 24, and 48 hours upon induction of pausing, and at 1, 3, 6, 12, 24, and 48 hours upon release of pausing in ES and TS cells. We find that ES, but not TS cells pause reversibly. To optimise developmental pausing conditions, we reasoned that by understanding the difference in pausing response of ES and TS cells, we could identify which pathways are essential for pausing. We found that KEGG pathways related to amino acid degradation, fatty acid degradation, and DNA repair are upregulated in ES cells, but downregulated in TS cells during entry into pausing. Moreover, by targeted metabolomics, we found a depletion of short chain carnitines in the paused ES cells. To extend the length of developmental pausing, we supplemented paused embryos with L-carnitine. The L-carnitine supplementation facilitates lipid usage and prolongs the pausing length by 19 days through the establishment of a more dormant state.
