    Resolving
    Fates and Single-Cell Transcriptomes of Hematopoietic Stem Cell Clones by PolyloxExpress Barcoding

    Scientists found that differentiation-inactive, multilineage, and lineage-restricted hematopoietic stem cell clones reside in distinct regions of the transcriptional landscape of hematopoiesis.

    Micro-Environmental
    Sensing by Bone Marrow Stroma Identifies IL-6 and TGFβ1 as Regulators of Hematopoietic Aging

    Inhibition of TGFβ signaling led to reversal of age-associated hematopoietic stem cell (HSC) platelet lineage bias, increased generation of lymphoid progenitors and rebalanced HSC lineage output in transplantation assays.

    Targeted
    Gene Correction of Human Hematopoietic Stem Cells for the Treatment of Wiskott – Aldrich Syndrome

    Scientists showed that a CRISPR/Cas9-based genome editing strategy allowed the precise correction of Wiskott-Aldrich syndrome mutations in up to 60% of human hematopoietic stem and progenitor cells, without impairing cell viability and differentiation potential.

    Metabolic
    Regulation of Inflammasome Activity Controls Embryonic Hematopoietic Stem and Progenitor Cell Production

    The authors demonstrated that NLRP3 inflammasome-mediated interleukin-1-beta signaling drives hematopoietic stem and progenitor cell production in response to metabolic activity.

    Efficient
    and Nontoxic Biomolecule Delivery to Primary Human Hematopoietic Stem Cells Using Nanostraws

    Scientists used nanostraws to target human primary hematopoietic stem and progenitor cells and showed efficient delivery of mRNA, short interfering RNAs, DNA oligonucleotides, and dextrans of sizes ranging from 6 kDa to 2,000 kDa.

    A
    Novel Approach to Genetic Engineering of T-Cell Subsets by Hematopoietic Stem Cell Infection with a Bicistronic Lentivirus

    Designed novel lentiviral constructs harbored a global promoter regulating mCherry for hematopoietic stem cell selection and a T-cell specific promoter upstream of eGFP.

    In Vitro
    Comparison of the Effects of Imatinib and Ponatinib on Chronic Myeloid Leukemia Progenitor/Stem Cell Features

    Researchers compared the effects of tyrosine kinase inhibitors belonging to different generations, imatinib and ponatinib, on progenitor/stem cell expansion potential and markers.

    Nicotinamide
    Inhibits Self-Renewal and Induces Granulocyte Differentiation of Multipotent Progenitor Cells

    Investigators assessed the effect of nicotinamide on myeloid differentiation of the IL-3 dependent, multipotent hematopoietic progenitor cell line FDCP-Mix.

    Abstract

    Intracoronary
    Injection of Hematopoietic Precursor Cells Regenerates the Borders, but Not the Core, of Old Myocardial Scars

    The authors studied function recovery at the scar zone and its impact in global left ventricular function after intracoronary injection of hematopoietic precursor cells.

    CLINICAL RESEARCH

    Short Telomere Length Predicts Non-Relapse Mortality after Stem Cell Transplantation for Myelodysplastic Syndrome

    Researchers measured relative telomere length in pre-transplant recipient blood samples in 1514 myelodysplastic syndrome (MDS) patients and evaluated the association of telomere length with MDS disease characteristics and transplantation outcomes.

    Abstract

    Predicting
    Non-Relapse Mortality following Allogeneic Hematopoietic Cell Transplantation during First Remission of Acute Myeloid Leukemia

    Scientists developed a comprehensive system for predicting non-relapse mortality after allogeneic hematopoietic cell transplantation during first complete remission of acute myeloid leukemia.

    Autologous
    Hematopoietic Stem Cell Transplantation for Refractory Stiff-Person Syndrome: The UK Experience

    Autologous hematopoietic stem cell transplantation was an intensive but well tolerated and effective treatment option for patients with Stiff Person Syndrome refractory to conventional immunotherapy.

    New Preclinical Models for Angioimmunoblastic T-Cell Lymphoma: Filling the GAP

    The authors provide a summary of the pathology, the transcriptional profile and genetic and immune-phenotypic features of human angioimmunoblastic lymphoma (AITL). In addition, they give an overview of preclinical models that recapitulate more or less faithfully human AITL characteristics and pathology.
