Heterozygous pathogenic germline ETV6 variants are associated with Thrombocytopenia 5 (T5), a poorly-understood genetic condition predisposing to thrombocytopenia and hematologic malignancies. To elucidate how germline ETV6 variants impact the HSPC compartment and contribute to disease, we generated a knock-in mouse harboring an Etv6R355X loss-of-function variant, which represents the mouse equivalent to the T5-associated variant ETV6R359X. more...

(Submitter supplied) Erg is an ETS family transcription factor frequently overexpressed in human leukemias and has been implicated as a key regulator of hematopoietic stem cells (HSCs). However how Erg controls normal hematopoiesis, particularly at the stem cell level, remains poorly understood. Using homologous recombination, we generated an Erg knockdown allele (Ergkd) in which Erg expression can be restored upon Cre-mediated excision of a Stopper cassette. more...

(Submitter supplied) Haematopoietic stem and progenitor cells (HSPCs), the precursors of all blood cells, reside predominantly in the bone marrow. Yet, a small proportion (<1%) of phenotypic HSPCs is also found in extramedullary tissues, such as spleen, where they contribute to blood production under stress conditions. However, the detailed characterization of extramedullary HSPCs remains poor. Here, we analyse the single-cell composition of the adult human HSPC pool within the spleen from two patients with hereditary spherocytosis (HS), a disorders causing abnormal red blood cells. more...

(Submitter supplied) Haematopoietic stem cells (HSCs) and multipotent progenitors (MPPs), the precursors of all blood cells, reside predominantly in the bone marrow (BM). Recent evidence suggests that other anatomical sites may contribute significantly to blood production, but the cellular, molecular and functional composition of extramedullary HSC/MPP pools remains unexplored. Here, we have compared the transcriptomes of single cells sorted from the phenotypic HSC/MPP pool of adult bone marrows and spleens from the same donors.

(Submitter supplied) Inherited thrombocytopenia results in low platelet counts and increased bleeding. Subsets of these patients have monoallelic germline mutations in ETV6 or RUNX1 and a heightened risk of developing hematologic malignancies. Utilizing CRISPR/Cas9, we compared the in vitro phenotype of hematopoietic progenitor cells and megakaryocytes derived from induced pluripotent stem cell (iPSC) lines harboring mutations in either ETV6 or RUNX1. more...

(Submitter supplied) An IRF8-dependent subset of classical dendritic cells (cDCs), termed DC1, effectively cross-primes CD8+ T cells and facilitates antitumor T cell responses. Etv6 is an ETS family transcription factor that controls hematopoietic stem and progenitor cell (HSPC) function. We report that like HSPC, cDCs express Etv6 but not its antagonist ETS1, whereas interferon-producing plasmacytoid dendritic cells (pDCs) express both factors. more...

(Submitter supplied) Hematopoietic stem cells are both necessary and sufficient to sustain the complete blood system of vertebrates. Here we show that Nfix, a member of the nuclear factor I (Nfi) family of transcription factors, is highly expressed by hematopoietic stem and progenitor cells (HSPC) of murine adult bone marrow. Although shRNA mediated knockdown of Nfix expression in Lineage-Sca-1+c-Kit+ HSPC had no effect on in vitro cell growth or viability, Nfix-depleted HSPC displayed a significant loss of colony forming potential, as well as short- and long-term in vivo hematopoietic repopulating activity. more...

(Submitter supplied) Germline mutations in ETV6 are associated with a syndrome of thrombocytopenia and leukemia predisposition, and ETV6 is among the most commonly mutated genes in leukemias, especially childhood B cell acute lymphoblastic leukemia. However, the mechanisms underlying disease due to ETV6 dysfunction are poorly understood. In order to address these gaps in knowledge, using CRISPR/Cas9, we developed a mouse model of the most common recurrent, disease-causing germline mutation in ETV6, which recapitulates aspects of human disease. more...

(Submitter supplied) The study is to obtain a transcriptome-wide map of prenatal murine stem and progenitor cells. VavCre+ mice were used for conditional knockout of Ddx41. Wild-type, Ddx41 heterozygous (Ddx41+/-) and Ddx41 knockout (Ddx41-/-) LSK cells from embryonic 14.5 day fetal liver were harvested (three samples from each group) for RNA. Gene expression analysis and alternative splicing analysis were performed. RNA-seq data were confirmed by RT-qPCR and regular PCR followed by gel quantification. more...

(Submitter supplied) Fetal hematopoietic stem and progenitor cells (HSPCs) migrate from fetal liver (FL) to bone marrow (BM) around birth. While adult BM HSPCs and their extrinsic regulation is well studied, little is known about the composition, function, and extrinsic regulation of the first HSPCs to enter the BM. Here, we show that HSPCs colonize multiple fetal bones by E15.5, shift from an MPP2 to an MPP3/4-dominant phenotype by birth, and display little function until E18.5, relative to their FL counterparts. We establish a transcriptional atlas of single perinatal HSPCs, and their putative BM niches, from E15.5 through P0 and show that early fetal BM (FBM) lacks HSPCs with intrinsic stem cell programs and niche cells supportive of HSPCs. In contrast, stem cell programs are preserved in neonatal BM HSPCs, which engage with a niche expressing HSC supportive factors distinct from those seen in adult BM (i.e., IGF).
