(Submitter supplied) Blood develops in distinct stages. Haematopoietic progenitors in the embryo manifest restricted differentiation potential relative to definitive haematopoietic stem cells in adult bone marrow, which support lifelong multilineage haematopoiesis. To identify regulators of embryonic haematopoiesis, we screened chromatin modifiers and identified the Polycomb group protein EZH1 as a barrier to multilineage potential from pluripotent stem cells (PSCs). more...

(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) Human hematopoietic stem cell (HSC) ontogeny is poorly defined due to the inability to identify HSCs as they emerge and mature in different hematopoietic sites. We created a single-cell transcriptome map of human hematopoietic tissues from 1st trimester to birth and found that HSC signature RUNX1+HOXA9+MLLT3+MECOM+HLF+SPINK2+ distinguishes HSCs from progenitors throughout gestation. In addition to the AGM (aorta-gonad-mesonephros) region, nascent HSCs populated the placenta and yolk sac before colonizing the liver at 6 weeks. more...

(Submitter supplied) Generation of abundant engraftable hematopoietic cells from autologous tissues promises new therapies for hematologic diseases. Differentiation of pluripotent stem cells into hematopoietic cells results in emergence of cells that have poor engraftment potential. To circumvent this hurdle, we have devised a vascular niche model to phenocopy the developmental microenvironment of hemogenic cells thereby enabling direct transcriptional reprogramming of human endothelial cells (ECs) into hematopoietic cells. 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) Ezh1 is a protein member of PRC2. Ezh1 has been described as a functional repressor gene, such as its homologous Ezh2. We are investigating the role of Ezh1 in hematopoietic stem cells, aging, self-renewal and differentiation. We used microarrays to detail the global program of gene expression in LSK cells from mice with knocked-down expression of Ezh1.

(Submitter supplied) Epigenetic modifications must underlie lineage-specific differentiation since terminally differentiated cells express tissue-specific genes, but their DNA sequence is unchanged. Hematopoiesis provides a well-defined model of progressive differentiation in which to study the role of epigenetic modifications in cell fate decisions. Multi-potent progenitors (MPPs) can differentiate into all blood cell lineages, while downstream progenitors commit to either myeloerythroid or lymphoid lineages. more...

(Submitter supplied) We tested whether the sustained hematopoietic differentiation of hPSCs can be achieved in defined cell culture conditions without addition of hematopoietic cytokines. Here we show that the endogenous stimuli were sufficient to induce a robust generation of clonogenic hematopoietic progenitors, maturation of blood cells, emergence of the definitive cell lineages, and progenitors that were phenotypically identical to early human embryonic hematopoietic stem cells (HSCs). more...

(Submitter supplied) Conditional deletion of Geminin from the entire hematopoietic compartment using Vav1:iCre mice led to defective hematopoiesis/dyserythropoiesis in E15.5 mouse embryos. The present data set includes data from lineage-negative cells isolated from homogenized livers that were dissected from E15.5.dpc embryos. The two conditions compared were wild-type versus Geminin-KO Lin- cells. The cells were collected from littermates.

(Submitter supplied) Bmi1 is a component of polycomb repressive complex 1 and its role in the inheritance of the stemness of adult somatic stem cells has been well characterized. Bmi1 maintains the self-renewal capacity of adult stem cells, at least partially, by repressing the Ink4a/Arf locus that encodes a cyclin-dependent kinase inhibitor, p16Ink4a, and a tumor suppressor, p19Arf 14. Deletion of both Ink4a and Arf in Bmi1-deficient mice substantially restored the defective self-renewal capacity of HSCs and neural stem cells.

(Submitter supplied) We performed morphogen-directed differentiation of human PSCs into HE followed by combinatorial screening of 26 candidate HSC-specifying TFs for the potential to promote hematopoietic engraftment in irradiated immune deficient murine hosts. We recovered seven TFs (ERG, HOXA5, HOXA9, HOXA10, LCOR, RUNX1, SPI1) that together were sufficient to convert HE into hematopoietic stem and progenitor cells (HSPCs) that engraft primary and secondary murine recipients

(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) The classical tenet of hematopoiesis posits well-accepted lineage trees that arise from progressively restricted oligopotent and unipotent progenitor populations. However, because fate in hematopoiesis has mostly been studied in the context of transplantation, it is unclear whether these lineage branches and such proposed oligopotent progenitors exist in an unperturbed hematopoietic system. Here, we utilize endogenous transposon tagging to trace the fate of thousands of progenitors and stem cells over time to re-evaluate these dogmas. more...
