(Submitter supplied) Haematopoietic stem cells (HSCs) have long been the focus of developmental and regenerative studies, yet our understanding of the signalling events regulating their specification remains incomplete. We demonstrate that supt16h, a component of the FAcilitates Chromatin Transcription (FACT) complex, is required for HSC formation. Zebrafish supt16h mutants express reduced levels of Notch signalling components, genes essential for HSC development, due to abrogated transcription. more...

(Submitter supplied) Chromatin organization and accessibility are fundamental to how genes are transcriptionally controlled. We identify the first vertebrate mutant for supt16h, a component of the FACT (FAcilitates Chromatin Transcription) complex along with Ssrp1 known to reorganize nucleosomes and assist in transcriptional elongation. We demonstrate its importance in hematopoietic stem cell (HSC) specification by regulating the elongation of Notch genes. more...

(Submitter supplied) Successful ex vivo expansion of hematopoietic stem cells (HSCs) would greatly benefit the treatment of disease and the understanding of critical questions of stem cell biology. Microarray studies showed that the HSC supportive mouse fetal liver CD3+ cells specifically expressed angiopoietin-like 2 (Angptl2) and angiopoietin-like 3 (Angptl3). When highly enriched HSCs were cultured in the presence of Angptl2 or Angptl3 together with saturating levels of other growth factors for 10 days, a 24 or 30 fold net expansion of long-term HSCs was observed by reconstitution analysis. more...

(Submitter supplied) Multiple signaling pathways contribute to blood cell formation in the fetus, but a role for innate immune/inflammatory signaling has not been described. Here we show that mouse fetuses deficient for either interferon gamma 1 (IFNg) or its receptor have decreased numbers of lymphoid progenitors and hematopoietic stem cells (HSCs) in the aorta/gonad/mesonephros region and placenta. The role of IFNg signaling was evolutionarily conserved, as morpholino knockdown of IFNg and its receptor reduced the number of hematopoietic stem and progenitor cells in the dorsal aorta and caudal hematopoietic territory of zebrafish embryos, and rag2 expressing cells in the thymus. more...

(Submitter supplied) Hematopoietic Stem Cells (HSC) are originated during embryonic development from endothelial-like cells located in the ventral side of the dorsal aorta around day E10-12 of murine development. This region is called AGM for Aorta/Gonad/Mesonephros refering to the tissues around the hemogenic aorta. Hematopoiesis depends on the Notch pathway and the identification of Notch-targets is important for the understanding of blood origin.

(Submitter supplied) In this study, we interrogated the role of DNA methylation in HSPC generation by taking advantage of dnmt1 knockout/knockdown embryos in zebrafish. First, we generated a comprehensive DNA methylation landscape of EHT, which revealed gradually hypermethylated regions associated with vasculogenesis. Taking advantage of dnmt1-deficient embryos, we showed that the decreased DNA methylation blocked HSPC emergence. more...

(Submitter supplied) Hypercholesterolemia, the driving force of atherosclerosis, accelerates the expansion and mobilization of hematopoietic stem and progenitor cells (HSPCs). The molecular determinants connecting hypercholesterolemia with hematopoiesis are underexplored. Here we report that a novel somite-derived pro-hematopoietic cue, AIBP, orchestrates HSPC emergence from the hemogenic endothelium, a type of specialized endothelium manifesting hematopoietic potential. more...

(Submitter supplied) Across species, hematopoietic stem and progenitor cells (HSPCs) arise during embryogenesis from a specialized arterial population, termed hemogenic endothelium. Here, we describe a mechanistic role for the epigenetic regulator, Enhancer of zeste homolog-1 (Ezh1) in vertebrate HSPC production via regulation of hemogenic commitment. Loss of ezh1 in zebrafish embryos favored acquisition of hemogenic (gata2b) and HSPC (runx1) fate at the expense of the arterial program (ephrinb2a, dll4). more...

(Submitter supplied) How the stemness of adult stem cells and cancer stem cells is regulated by environmental cues through surface receptors is poorly understood. In this gene expression analysis, we found that, in the mouse MLL-AF9 acute myeloid leukemia (AML) model, a deficiency in intracellular signaling of inhibitory receptor PIR-B resulted in increased differentiation and decreased stemness of leukemia stem cells, revealing that PIR-B supports leukemia development. more...

(Submitter supplied) Purpose: Since Nlrc3 signaling is imperative for HSPCs production in zebrafish, to further determine the regulatory mechanism by which nlrc3 signaling regulates HSPCs. Bulk RNA sequencing analysis is performed to dissect the function and molecular mechanism between the control groups and the nlrc3 morphants groups. Methods: The GFP+ cells in Tg(fli1a:eGFP) zebrafish embryos at 28 hpf were sorted, which is the stage that EHT occurs in the VDA and the site of hemogenic endothelial cells onset. more...

(Submitter supplied) RNA was isolated from control and mettl3 or ythdf2 morphants zebrafish cells using the TRIzol (Invitrogen) reagent by following the company manual. For all samples the RNA integrity was checked using an Agilent Bioanalyzer 2100. All samples showed a RIN (RNA integrity number) of higher than 9. Approximately 2.5 µg of total RNA was then used for library preparation using a TruSeq™ RNA Sample Prep Kit v2 (Illumina, San Diego, CA, USA) according to the manufacturer’s protocol.The libraries were sequenced using HiSeq2500 or HiSeq 3000 (Illumina) in paired-read mode, creating reads with a length of 101 or 151 bp. more...
