Human yolk sac-like haematopoiesis generates RUNX1-, GFI1- and/or GFI1B-dependent blood and SOX17-positive endothelium

Project description:The genetic regulatory network controlling early fate choices during human blood cell development are not well understood. We use human pluripotent stem cell reporter lines to track the development of endothelial and haematopoietic populations in an in vitro model of human yolk-sac development. We identified SOX17-CD34+CD43- endothelial cells at day 2 of blast colony development, as a haemangioblast-like branch point from which SOX17-CD34+CD43+ blood cells and SOX17+CD34+CD43- endothelium subsequently arose. Most human blood cell development was dependent on RUNX1. Deletion of RUNX1 only permitted a single wave of yolk sac-like primitive erythropoiesis, but no yolk sac myelopoiesis or aorta-gonad-mesonephros (AGM)-like haematopoiesis. Blocking GFI1/1B activity with a small molecule inhibitor abrogated all blood cell development, even in cell lines with an intact RUNX1 gene. Together, our data defines the hierarchical requirements for both RUNX1 and GFI1/1B during early human haematopoiesis arising from a yolk sac-like SOX17- haemogenic endothelial intermediate.

Expression data from Tnrc6a (GW182) mutant yolk sac

2011-09-01 | GSE30244 | GEO

Expression data from Tnrc6a (GW182) mutant yolk sac

Project description:GW182 (Tnrc6a) is a key component of RISC (miRNA-Induced Silencing Complex) that plays a critical role in miRNA-mediated gene silencing. Here, we show that GW182 is expressed in the yolk sac endoderm, and that gene-trap disruption of GW182 leads to growth arrest of yolk sac endoderm, impaired hematopoiesis and embryonic lethality. To investigate roles of GW182 in the yolk sac endoderm, we assessed changes in mRNA expression in the yolk sac of E9.5 GW182gt/gt embryos using microarrays (Affymetrix). Yolk sac of wild type littermates and GW182gt/gt embryos at E9.5 was collected for total RNA isolation using Trizol (Invitrogen). RNAs were purified according to the manufacturer’s protocol before subjected to Mouse Gene 1.0 ST Whole Genome Array (Affymetrix) for mRNA expression profiling. Experiments were performed in triplicate. Differentially expressed mRNAs were identified using a two-sample t-test (P<0.05 considered significant).

The role of the yolk sac in human fetal development and identification of a hepatocyte-like cell in the human yolk sac

Project description:The human yolk sac (YS) is an extra-embryonic tissue critical for early prenatal life development. It is the first site of haematopoiesis where progenitors differentiate from endoderm within blood islands of the yolk sac contributing initially to primitive erythropoiesis and in subsequent waves to erythro-myeloid and lymphoid differentiation.

Human fetal yolk sac scRNA-seq data (sample ID: F158 for Haniffa Lab; 16099 for HDBR)

Project description:Investigating the blood, immune and stromal cells present in a human fetal embryo in a world first single cell transcriptomic atlas. The embryo was dissected into 12 coronal sections, yolk sac, and yolk sac stalk. Live single cells sorted, with cell suspension then undergoing 10x chromium 5 prime scRNA-seq. This accession contains the yolk sac and yolk sac stalk data from this embryo. A matched accession contains the coronal section data. Lane "WS_wEMB12142156" (from yolk sac) was excluded from downstream analysis due to low fraction reads in cells post-CellRanger QC. Termination procedure for this embryo was medical. The F158_[features...barcodes...matrix].[tsv...mtx].gz files attached to this accession represent raw count data from all the 10x lanes in this accession combined, and as output from CellRanger filtered matrices (CellRanger version 6.0.1 using human reference genome GRCh38-2020-A). One set of count matrices relates to the yolk sac data, and one set of count matrices relates to the yolk sac stalk data.

Identification of Erythroid-Enriched Gene Expression in the Mouse Embryonic Yolk Sac using Microdissected Cells

Project description:Primitive erythropoiesis in the mouse yolk sac is followed by definitive erythropoiesis resulting in adult erythrocytes. In comparison to definitive erythropoiesis little is known about the genes that control the embryonic erythroid program. The purpose of this study was to generate a profile of mouse embryonic yolk sac erythroid cells and identify novel regulatory genes differentially expressed in erythroid compared to non-erythroid (epithelial cells). The identification of these genes will contribute to a greater understanding of how the primitive erythroid program is controlled. This work will have clinical implications for treating sickle cell anemia and β-thalassemia. Activating genes in adult erythroid cells that increase embryonic or fetal globin gene expression may be a therapeutic approach to treat individuals with these disorders. Keywords: Comparison between mouse embryonic day 9.5 yolk sac microdissected primitive erythroid precursors and epithelial cells

Gene expression profiling of rudhira null embryo and yolk sac at 9.5 dpc

Project description:Rudhira is essential for mouse developmental angiogenesis and tissue morphogenesis. Embryos lacking endothelial rudhira die at mid-gestation with vascular patterning defects. Rudhira mutant yolk sac endothelial cells show slow and random migration. So to identify key signaling pathways perturbed in the absence of rudhira, we undertook whole transcriptome based analysis of gene expression in rudhira null yolk sac and embryo. Transcriptome analysis shows that key mediators of angiogenesis, cell adhesion, migration and extracellular matrix degradation as well as several components of the TGFÎ² pathway are perturbed in rudhira null mutant yolk sacs at 9.5 dpc. We used two embryo samples ( 2E- wild type; 5E- rudhira mutant). Repetition was done on each sample. We used 4 yolk sac samples (3Y,4Y- wild type; 7Y,8Y-rudhira mutant) for the analysis. Repetition was done on each sample.
