(Submitter supplied) Single cell RNA-Seq time-course analysis revealed that as pre-HSCs mature into fetal liver-stage HSCs they show signs of interferon exposure, multi-lineage differentiation gene expression signatures, and prolonged cell cycle reminiscent of quiescent adult HSCs.

(Submitter supplied) Tracing the emergence of the first hematopoietic stem cells (HSCs) in human embryos, particularly the scarce and transient precursors thereof, is so far challenging, largely due to technical limitations and material rarity. Here, using single-cell RNA sequencing, we constructed the first genome-scale gene expression landscape covering the entire course of endothelial-to-HSC transition during human embryogenesis. more...

(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) Hematopoietic stem cells (HSCs) maintain the entire blood system throughout the life and are utilized for a therapeutic component of blood diseases. The zebrafish is an elegant genetic model for the study of hematopoiesis due to its many unique advantages. We have developed the method to isolate zebrafish HSCs by a combination of two HSC-related transgenic lines, gata2a:GFP and runx1:mCherry. In this study, we performed RNA-seq analysis in three distinct hematopoietic cell populations in the adult kidney, gata2a+ runx1+ cells (HSCs), gata2a− runx1+ cells (erythroid- and/or myeloid-primed progenitors), and gata2a+ runx1− cells (lymphoid-primed progenitors).

(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) The purpose of the experiment was to define the heterogeneity of hematopoietic stem and progenitor cells (HSPC) at emergence and initial maturation using scRNA-Seq of enriched blood populations from transgenic fluorescent zebrafish (30 and 52 hpf). Results provide insight into the different HSPC populations in heamtopoietic development.

(Submitter supplied) We performed multi-omics exploration of early aorta endothelial cells (AECs), hemogenic endothelial cells (HECs), pre-HSCs and long-term HSCs (LT-HSCs) along definitive HSC emergence in mouse embryos. Globally, we find that most hematopoiesis related enhancers were already pre-activated at the beginning, followed by strengthened looping structure of enhancers and promoters. After the stronger interactions forming, enhancers can be further activated to promote hematopoiesis gene expressions. more...

(Submitter supplied) We report the application of single-molecule-based sequencing technology for high-throughput profiling of histone modifications in mammalian cells. By obtaining over four billion bases of sequence from chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of mouse embryonic stem cells, neural progenitor cells and embryonic fibroblasts. We find that lysine 4 and lysine 27 trimethylation effectively discriminates genes that are expressed, poised for expression, or stably repressed, and therefore reflect cell state and lineage potential. more...

(Submitter supplied) Disrupting mutations of the RUNX1 gene are found in 10% of patients with myelodysplasia (MDS) and 30% of patients with acute myeloid leukemia (AML). Previous studies have revealed an increase in hematopoietic stem cells (HSCs) and multipotent progenitor (MPP) cells in conditional Runx1-knockout (KO) mice, but the molecular mechanism is unresolved. We investigated the myeloid progenitor (MP) compartment in KO mice, arguing that disruptions at the HSC/MPP level may be amplified in downstream cells. more...

(Submitter supplied) RUNX1 is crucial for multiple stages of hematopoiesis and its mutation can cause familial platelet disorder with predisposition to acute myeloid leukemia (FPD/AML). We aim to study the role of RUNX1 in megakaryocyte-biased HSCs differentiation to megakaryocytes. Here, by using Runx1F/FMx1-Cre mouse model ,we sorted CD41pos HSCs and CD41neg HSCs in both RUNX1 WT and KO, and tested the RUNX1 direct binding targets in these cells genome.

(Submitter supplied) Hematopoietic stem cells (HSCs) must ensure adequate blood cell production following distinct external stressors. A comprehensive understanding of in vivo heterogeneity and specificity of HSC responses to external stimuli is currently lacking. We performed single-cell RNA sequencing (scRNA-Seq) on functionally validated mouse HSCs and LSK (Lin-, c-Kit+,Sca1+) progenitors after in vivo pharmacological perturbation of niche signals interferon, granulocyte-colony stimulating factor (G-CSF), and prostaglandin. more...
