    A Mechanosensitive Lipolytic Factor in the Bone Marrow Promotes Osteogenesis and Lymphopoiesis

    Mechanistically, reticulocalbin-2 binds to a functional receptor complex, which is composed of neuronilin-2 and integrin beta-1, to activate a cAMP-PKA signaling pathway that mobilizes bone marrow fat via lipolysis to fuel the differentiation and function of mesenchymal and hematopoietic stem cells.

    Precise CRISPR-Cas–Mediated Gene Repair with Minimal Off-Target and Unintended On-Target Mutations in Human Hematopoietic Stem Cells

    In combination with adeno-associated virus serotype 6 template delivery, the authors’ approach led to efficient HDR in human hematopoietic stem and progenitor cells and T cells, with minimal NHEJ-mediated on-target mutations.

    Abstract

    CLASP2 Safeguards Hematopoietic Stem Cell Properties during Mouse and Fish Development

    Researchers showed that, in the absence of CLASP2, a microtubule-associated protein, the overall production of hematopoietic stem cells (HSCs) was reduced, and the produced HSCs failed to self-renew and maintain their stemness throughout mouse and zebrafish development.

    Fbxw11 Impairs the Repopulation Capacity of Hematopoietic Stem/Progenitor Cells

    Scientists demonstrated that Fbxw11 plays a negative role in the maintenance of hematopoietic stem/progenitor cells in vitro and repopulation capacity in vivo.

    Acute Lymphoblastic Leukemia-Secreted miRNAs Induce a Proinflammatory Microenvironment and Promote the Activation of Hematopoietic Progenitors

    Investigators identified three miRNAs, miR-146a-5p, miR-181b-5p, and miR-199b-3p, as potential candidates for TLR8 ligation, which are overexpressed in acute lymphoblastic leukemia and show agonist functional binding.

    Abstract

    Spliceosome Inhibitor Induces Human Hematopoietic Progenitor Cell Reprogramming toward Stemness

    The authors demonstrated that human committed hematopoietic progenitors could be reprogrammed into multipotent progenitors by spliceosome inhibitor.
