(Submitter supplied) The transcription factor RUNX1 is required in the embryo for formation of the adult hematopoietic system. Here we describe the seminal findings that led to the discovery of RUNX1 and of its critical role in blood cell formation in the embryo from hemogenic endothelium. We also present RNA-Seq data demonstrating that hemogenic endothelial cells in different anatomic sites, which produce hematopoietic progenitors with dissimilar differentiation potentials, are molecularly distinct. 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) Inversion of chromosome 16 is a consistent finding in patients with acute myeloid leukemia subtype M4 with eosinophilia (AML M4Eo), which generates a CBFB-MYH11 fusion gene. It is generally considered that CBFβ-SMMHC, the fusion protein encoded by CBFB-MYH11, is a dominant negative repressor of RUNX1. However, recent findings challenge the RUNX1-repression model for CBFβ-SMMHC mediated leukemogenesis. more...

(Submitter supplied) Identification of the regulators that lead to arterial specification with definitive hematopoietic potential should help to design strategies to recapitulate HSC development from human pluripotent stem cells (hPSCs). Here, using ETS1 conditional H1 hESC line, we found that ETS1 induction at the mesodermal stage of differentiation dramatically enhances the arterial specification in hPSC cultures and formation of DLL4+CXCR4+/- arterial HE with lymphoid potential and the capacity to produce red blood cells with high expression of BCL11a and b-globin. more...

(Submitter supplied) Recently, we identified and characterized specific endothelial progenitors with varying hemogenic potential during human pluripotent stem cell differentiation. Based on these studies we established a platform on which we can manipulate NOTCH signaling on these subsets to elucidate the specific role of this signaling pathway during hemogenic endothelial specification, endothelial-to-hematopoietic transition, and definitive hematopoietic specification.

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) 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...
