(Submitter supplied) Haematopoietic stem cells (HSCs) are derived early from embryonic precursor cells, such as haemogenic endothelial cells and pre-HSCs. However, the identity of precursor cells remains elusive due to their rareness, transience, and inability to be isolated efficiently. Here we employed potent surface markers to capture the nascent pre-HSCs at 30% purity, as rigorously validated by single-cell-initiated serial transplantation assay. more...

(Submitter supplied) Hematopoietic stem cells (HSCs) in adult are specified early from the endothelium-derived precursors (e.g., hemogenic endothelium, and pre-HSCs) in mouse mid-gestation embryos, the detailed process, however, is still largely unknown due to their rareness, transience, and current inability to prospectively isolate them efficiently . Here we developed a potent set of surface markers that could capture the earliest emerging HSCs, the CD45- pre-HSCs with high accuracy and purity, as rigorously and functionally verified by single-cell-initiated serial transplantation assays. more...

(Submitter supplied) Human hematopoietic stem cell (HSC) ontogeny is poorly defined due to the inability to identify HSCs as they emerge and mature in different hematopoietic sites. We created a single-cell transcriptome map of human hematopoietic tissues from 1st trimester to birth and found that HSC signature RUNX1+HOXA9+MLLT3+MECOM+HLF+SPINK2+ distinguishes HSCs from progenitors throughout gestation. In addition to the AGM (aorta-gonad-mesonephros) region, nascent HSCs populated the placenta and yolk sac before colonizing the liver at 6 weeks. more...

(Submitter supplied) To examine the role of Evi1 in HSC specification, we generated Tie2-Cre::ROSA-Evi1 mice, which can induce Evi1 in endothelial cells. We observed five-fold increase of HSCs In Tie2-Cre::ROSA-Evi1 embryo. To characterize the induced HSCs in Tie2-Cre::ROSA-Evi1 embryos, we analyzed the gene expression profile of HSCs.

(Submitter supplied) During ontogeny, HSCs or progenitors are generated from endothelial cells through the process known as endothelial-to-hematopoietic transition (EHT). After EHT, hematopoietic cells form cell aggregates, called hematopoietic clusters. To obtain mechanistic insight into HSC specification, we compared the gene expression profiles of hematopoietic clusters between caudal half region and yolk sac.

(Submitter supplied) Definitive hematopoietic stem cells (HSCs) bud off from the hemogenic endothelial cells (HEC) located in the dorsal aorta of the mouse embryo. The maturation of HSCs from HEC occurs through the precursor of HSCs (pre-HSCs) between embryonic day (E) 9.5 and E11.5. To clarify the differentiation process of pre-HSCs, we performed single-cell RNA-seq analysis of cells dissociated from the dorsal aorta and its surrounding tissues and the fetal liver at E10.5 and E11.5. more...

(Submitter supplied) Developmental pathways that orchestrate the fleeting transition of endothelial cells into haematopoietic stem cells remain undefined. Here we demonstrate a tractable approach for fully reprogramming adult mouse endothelial cells to haematopoietic stem cells (rEC-HSCs) through transient expression of the transcription-factor-encoding genes Fosb, Gfi1, Runx1, and Spi1 (collectively denoted hereafter as FGRS) and vascular-niche-derived angiocrine factors. more...

(Submitter supplied) We present single-cell mRNA-Sequencing of various endothelial and hematopoietic populations isolated from the mouse embryonic aorta at E10 and E11. Our study reveals the transcriptional dynamics occuring during endothelial to hematopoietic transition, the process responsible for the production of hematopoietic stem cells.

(Submitter supplied) Blood develops in distinct stages. Haematopoietic progenitors in the embryo manifest restricted differentiation potential relative to definitive haematopoietic stem cells in adult bone marrow, which support lifelong multilineage haematopoiesis. To identify regulators of embryonic haematopoiesis, we screened chromatin modifiers and identified the Polycomb group protein EZH1 as a barrier to multilineage potential from pluripotent stem cells (PSCs). more...

(Submitter supplied) During embryonic development, the first hematopoietic stem cells (HSCs) arise from a transient population of endothelial cells lining the ventral surface of the dorsal aorta, via a process of endothelial to hematopoietic transition (EHT) at embryonic day (E) 10.5. This region contains resident PDGFRA+ stromal cells (PSCs), but their identity and role in HSC generation in the AGM are not well understood. more...

(Submitter supplied) Generation of abundant engraftable hematopoietic cells from autologous tissues promises new therapies for hematologic diseases. Differentiation of pluripotent stem cells into hematopoietic cells results in emergence of cells that have poor engraftment potential. To circumvent this hurdle, we have devised a vascular niche model to phenocopy the developmental microenvironment of hemogenic cells thereby enabling direct transcriptional reprogramming of human endothelial cells (ECs) into hematopoietic cells. more...
