(Submitter supplied) During development a specialised subset of endothelial cells, the haemogenic endothelium, undergo an endothelial-to-haematopoietic transition. This process critically involves the transcription factor Runx1. Here we have isolated a specific subpopulation of endothelial cells using a Runx1 enhancer-reporter transgenic mouse line (23GFP). We have compared the gene expression profile of this population to non-23GFP expressing endothelial cells and CD41 expressing haematopoietic progenitor cells to assess whether 23GFP expression marks a biologically distinct subset of endothelium. 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) To examine the cell and molecular transitions between endothelial (E), hemogenic endothelial (HE), and intra-arterial clusters (IAC) cells, and the heterogeneity of hematopoietic stem and progenitor cells (HSPCs) within the IACs, we profiled ~40,000 cells from the caudal arteries (dorsal aorta, umbilical, vitelline arteries) of embryonic day (E) 9.5 to 11.5 mouse embryos by single-cell RNA sequencing (scRNA-Seq). more...

(Submitter supplied) To examine the cell and molecular transitions between endothelial (E), hemogenic endothelial (HE), and intra-arterial clusters (IAC) cells, we profiled ~1700 cells from the caudal arteries (dorsal aorta, umbilical, vitelline) of embryonic day (E) 10.5 mouse embryos by single-cell ATAC sequencing (scATAC-Seq). We found extensive cis--regulatory landscape change during the endothelial to hematopoietic transition (EHT).

(Submitter supplied) The goal of this study is to perform RNAseq in different sub-types of the zebrafish embryonic dorsal aorta (DA) at 28-30 hpf using TgBAC(runx1P2:Citrine);Tg(kdrl:mCherry) double-transgenic zebrafish embryos. A min. of 3000 cells per population were collected via FACS. RNA was isolated with the RNeasy Plus Micro Kit (QIAGEN, Cat No. 74034). High quality RNA (RIN > 8.0) was sent for RNAseq to the Wellcome Trust Centre for Human Genetics (WTCHG). more...

(Submitter supplied) The goal of this study is to analyse the open chromatin regions via ATACseq in different sub-types of the zebrafish embryonic dorsal aorta (DA) at 28-30 hpf using TgBAC(runx1P2:Citrine);Tg(kdrl:mCherry) double-transgenic zebrafish embryos. 2000-3000 cells were FAC-sorted directly into 100 µl of 1x HBSS/10 mM HEPES/0.25% BSA buffer for Tagmentation (as described by Buenrostro et al. (2013), Nat. Methods 10, 1213-1218), but with 1.5 µl Tn5 transposase (Illumina) in a 50 µl reaction volume. more...

(Submitter supplied) We used a murine ES cell line in which HoxA3 expression is under control of a tetracycline-responsive element and differentiated these cells as embryoid bodies (EBs). Endothelial (Flk-1 VE-cadherin double positive, FV) and hematopoieitc progenitors (c-Kit CD41 double positive, K41) were isolated from differentiated EBs that had been induced for 6 hours by doxycycline (Dox) treatment.

(Submitter supplied) We observe that HoxA3 represses hematopoieis by the repression of several transcription factors including Runx1 and Gata1. Up regulation of either Runx1 or Gata1 in the presence of HoxA3 reverted the hematopoietic repression. We have performed full genome analysis to determine the molecular signature of hematopoietic development in response to upregulation of Runx1 and Gata1.

(Submitter supplied) It has now been well established that hematopoietic stem and progenitor cells originate from a specialised subset of endothelium termed hemogenic endothelium (HE) via an endothelial-to-hematopoietic transition. However, the molecular mechanisms determining which endothelial progenitors possess or not this hemogenic potential is currently unknown. In this study, we investigated the changes in hemogenic potential in endothelial progenitors at the early stages of embryonic development. more...
