(Submitter supplied) Tissue-specific stem cells persist for a lifetime and can differentiate to maintain homeostasis or transform to initiate cancer. Despite their importance, there are no described quality assurance mechanisms for newly formed stem cells. We observed intimate and specific interactions between macrophages and blood stem cells in zebrafish embryos. Stressed stem cells were marked by surface Calreticulin, which stimulates macrophage interaction as an “eat me” signal. more...

(Submitter supplied) The BMP signaling pathway regulates multiple steps of hematopoiesis, mediated through receptor-regulated Smads, including Smad1 and Smad5. Here we use loss-of-function approaches in zebrafish to compare the roles of Smad1 and Smad5 during embryonic hematopoiesis. Microarray experiments revealed that the two proteins regulate redundantly the key initiators of the hemato-vascular program, including scl, lmo2, and gfi1. more...

(Submitter supplied) The global gene expression profiles of human umbilical cord blood and adult bone marrow CD34+CD33-CD38-Rho(lo)c-kit+ cells, enriched for hematopoietic stem/progenitor cells (HSC) with CD34+CD33-CD38-Rho(hi) cells, enriched in committed hematopoietic progenitor cells (HPC), were compared to identify candidate regulators of HSC self-renewal versus differentiation fate decisions.

(Submitter supplied) Clonal hematopoiesis (CH) results from enhanced fitness of a mutant hematopoietic stem and progenitor cell (HSPC), but how such clones expand is unclear. Here, we developed a technique that combines mosaic mutagenesis with color labeling of HSPCs to study how acquired mutations affect clonal fitness in a native environment. Mutations in CH-associated genes, like asxl1, promoted clonal dominance. Single-cell transcriptional analysis revealed that mutations stimulated expression of proinflammatory genes in mature myeloid cells and anti-inflammatory genes in progenitor cells of the mutant clone. more...

(Submitter supplied) Hematopoietic stem and progenitor cells (HSPCs) are able to self-renew and can give rise to all blood lineages throughout their lifetime, yet the mechanisms regulating HSPC development have yet to be discovered. In this study, we characterized a hematopoiesis defective zebrafish mutant line named smu07, which was obtained from our previous forward genetic screening, and found the HSPC expansion deficiency in the mutant. more...

(Submitter supplied) Clonal hematopoiesis of indeterminate potential is prevalent in elderly individuals and associated with increased risks of all-cause mortality and cardiovascular disease. However, mouse models to study the dynamics of clonal hematopoiesis and its consequences on the cardiovascular system under homeostatic conditions are lacking. We used a model of clonal hematopoiesis using adoptive transfer of unfractionated ten-eleven translocation 2-mutant (Tet2-mutant) bone marrow cells into nonirradiated mice. more...

(Submitter supplied) Except complement C1q, the immunological functions of other C1q family members have remained unclear. In vitro studies showed that DrC1q-like could inhibit the apoptosis induced by ActD and CHX in EPC cells, through repressing the activation of caspase 3/9. Moreover, its physiological roles were studied by morpholino-mediated knockdown in zebrafish embryogenesis We used microarrays to compare the global programme of gene expression of DrC1q-like deficient embryos and control embryos. 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) The objective of this study was to characterise macrophage subsets in bone marrow (BM) isolated from Csf1r-EGFP mice. A concurrent imaging flow cytometry study conducted by our team unexpectedly revealed macrophage surface marker staining emanates from membrane-bound subcellular remnants associated with unrelated cells. Expression data from sorted BM “macrophage” populations was found to be consistent with macrophage fragments associated with non-macrophage cells. more...

(Submitter supplied) Cells expressing macrophage markers (Cd11b+F4/80+CD169+CX3CR1neg) were sorted from the bone marrow of C57BL/6 mice and their gene expression profile analysed using RNA sequencing. Analysis of the most highly expressed genes revealed a gene expression signature consistent with a granulocyte population (i..e high expression of Ly6g and Cxcr2), rather than macrophages (i.e. low/negligible expression of Adgre1, Cd163 and Mertk). more...
