Uncovering human yolk sac-derived innate lymphoid-biased multipotent progenitors prior to hematopoietic stem cell formation (CITE-Seq)

ABSTRACT: Hematopoietic stem cell (HSC)-independent lymphopoiesis has been elucidated in murine embryos. However, our understanding regarding human embryonic counterparts remains limited. Here, we unveiled the presence of human yolk sac-derived lymphoid-biased progenitors (YSLPs) expressing CD34, IL7R, LTB and IRF8 at Carnegie Stage 10, much earlier than the first HSCs emergence. The number and lymphopoietic potential of these progenitors were both significantly higher in yolk sac than embryo proper at this early stage. Importantly, single-cell/bulk culture and CITE-seq have elucidated the tendency of YSLP differentiating into innate lymphoid cells and dendritic cells. Notably, lymphoid progenitors in fetal liver before and after HSCs seeding displayed distinct transcriptional features, with the former closely resembling those of YSLPs.

Uncovering human yolk sac-derived innate lymphoid-biased multipotent progenitors prior to hematopoietic stem cell formation (scRNA-Seq)

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.

Single cell transcriptome sequencing of CS11 and CS15 human yolk sacs

Project description:Yolk sac is an important site for early embryonic hematopoiesis. However, our understanding of early hematopoietic development is still very limited. Single cell transcriptome sequencing provides us with a good research method. Here, we performed single cell RNA-seq analysis for Carnegie stage 11 (CS11) and Carnegie stage 15 (CS15) human yolk sacs.

CD27 marks embryonic hematopoietic stem cells

Project description:Cell surface markers of adult hematopoietic stem cells (HSCs) are well established, but fewer markers are available for embryonic HSCs and their immediate precursors (pre-HSCs) in the major arteries. We performed RNA-Seq on a population of cells from the major arteries of embryonic day 11.5 mouse embryos enriched for lymphoid progenitors, pre-HSCs, and HSCs. We determined that Tnfrsf7, encoding CD27, a member of the tumor necrosis factor receptor superfamily, is upregulated in this population. CD27 is found on ~5% of hematopoietic cluster cells in the major arteries, and enriches for progenitors with lymphoid potential, embryonic HSCs, and Type II pre-HSCs (CD144+CD45+), and fetal liver HSCs. It does not, however, enrich for yolk sac derived erythro-myeloid progenitors. Collectively, those data show that CD27 is a new cell surface marker of embryonic HSCs and Type II pre-HSCs.

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).

Expression data from Satb1- and control-transduced LSK Flt3- cells

Project description:How hematopoietic stem cells (HSCs) produce specific lineages is not well understood. We searched for key factors that direct HSC to lymphopoiesis. Comparing gene expression profiles for HSCs and early lymphoid progenitors revealed that Satb1, a global chromatin regulator, was significantly induced with lymphoid lineage specification. HSCs from Satb1-null mouse were defective in lymphopoietic activity in culture, and failed to reconstitute T-lymphopoiesis in wild-type recipients. Furthermore, Satb1-transduction in HSCs, as well as in embryonic stem cells, robustly promoted their differentiation toward lymphocytes in culture. We prepared RNA samples from control or Satb1-transfected Lin- c-kitHi Sca-1+ Flt3- cells derived from WT mouse bone marrow.

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.
