(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...

(Submitter supplied) Embryonic hematopoiesis is regulated by the coordinated interaction between transcription factors and the epigenetic regulators driving developmental-stage specific gene expression but how this process drives hematopoietic specification and terminal differentiation is poorly understood. Here we generated RNA-Seq, DNase-Seq and ChIP-Seq data for histone marks and transcription factors from ES-cell derived purified cells representing six sequential stages of blood cell specification and differentiation. more...

(Submitter supplied) During ontogeny the transcription factor RUNX1 governs the emergence of definitive hematopoietic cells from specialized endothelial cells, called hemogenic endothelium (HE). The ultimate consequence of this endothelial-to-hematopoietic transition is the concomitant activation of the hematopoietic program and down-regulation of the endothelial program. However, due to the rare and transient nature of the HE, little is known about the initial role of RUNX1 within this population. more...

(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) 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) During embryogenesis, waves of hematopoietic progenitors develop from hemogenic endothelium (HE) prior to the emergence of self-renewing hematopoietic stem cells (HSC). Although previous studies have shown that yolk sac-derived erythromyeloid progenitors and HSC emerge from distinct populations of HE, it remains unknown whether the earliest lymphoid-competent progenitors, multipotent progenitors, and HSC originate from common HE. more...

(Submitter supplied) Hematopoietic stem and progenitor cells (HSPCs) originate from an endothelial-to-hematopoietic transition (EHT) during embryogenesis. Characterization of early hemogenic endothelial (HE) cells is required to understand what drives hemogenic specification and to accurately define cells capable of undergoing EHT. Using Cellular Indexing of Transcriptomes and Epitopes by Sequencing (CITE-seq), we defined the early subpopulation of pre-HE cells based on both surface markers and transcriptomes. more...
