(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) Hematopoietic stem cells (HSC) develop from hemogenic endothelium (HE) within embryonic arterial vessels such as the aorta of the aorta-gonad-mesonephros region (AGM). To identify the signals responsible for HSC formation, we used single cell RNA-sequencing to simultaneously analyze the transcriptional profiles of AGM-derived cells transitioning from HE to HSC, and AGM-derived endothelial cells which provide signals sufficient to support HSC maturation and self-renewal. 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) The aim of this study was to examine the whole transcriptome of pools of 20 cells of Gata3-expressing AGM subpopulations (haematopoietic [HC], mesenchymal [MC], sympathetic nervous system [SNS], and endothelial [EC]) and compare them to their non-Gata3 expressing counterparts

(Submitter supplied) The first hematopoietic stem cells originate from hemogenic endothelium (HE), that trans-differentiate into the lumen to form hematopoietic clusters. The molecular mechanisms driving this transition are only poorly understood. Here, we performed single cell RNA-seq profiling of HE cells utilising a RUNX1 and GFI1 reporter mouse line.This allowed for a detailed characterisation of HE cells during endothelial-to-hematopoietic transition. more...

(Submitter supplied) The emergence of definitive human haematopoietic stem cells (HSCs) during Carnegie Stages (CS) 14-17 in the aorta-gonad-mesonephros (AGM) region is a complex and tightly regulated process. In a previous study we conducted spatial transcriptomic analysis of the human AGM region at the end of this period (CS16/17) and identified secreted factors involved in HSC development. Here, we extend our analysis to investigate the progression of dorso-ventral polarized signalling around the dorsal aorta over the entire period of HSC emergence. more...

(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) A mouse AGM-derived cell line, AGM-s3, was shown to support the development of hematopoietic stem cells. To elucidate the molecular mechanisms regulating early hematopoiesis, we obtained subclones from AGM-s3, some of which were hematopoiesis supportive (s3-A9) and others which were non-supportive (s3-A7), and we analyzed the gene expression profiles by gene chip analysis.
