    Loss of Parathyroid Hormone Receptor Signaling in Osteoprogenitors Is Associated with Accumulation of Multiple Hematopoietic Lineages in the Bone Marrow

    Investigators reported that numbers of maturing myeloid, T cell, and erythroid populations were increased in the bone marrow of mice lacking parathyroid hormone receptor in osteoprogenitors.

    Abstract

    DNA Methylation Safeguards the Generation of Hematopoietic Stem and Progenitor Cells by Repression of Notch Signaling

    Scientists used multi-omics approaches together with functional assays to assess global DNA methylome dynamics during the endothelial cells-to-hematopoietic stem and progenitor cells (HSPCs) transition in zebrafish, and determined that DNA methyltransferase 1 was essential for HSPC generation via repression of Notch signaling.

    Abstract

    Differentiation Epitopes Define Hematopoietic Stem Cells and Change with Cell Cycle Passage

    Researchers concluded that primitive hematopoietic stem cells altered their differentiation potential with cell cycle progression and found that cycling stem cells expressed differentiation epitopes and altered their differentiation potential with cell cycle passage..

    Abstract

    Loss of SIRT1 Inhibits Hematopoietic Stem Cell Aging and Age-Dependent Mixed Phenotype Acute Leukemia

    Investigators found that Sirt1 knockout improved the maintenance of quiescence of aging HSCs and their functionality as well as mouse survival in serial bone marrow transplantation recipients.

    Abstract

    Comparative Analysis of Decitabine Intensified BUCY2 and BUCY2 Conditioning Regimen for High-Risk MDS Patients Undergoing Allogeneic Hematopoietic Stem Cell Transplantation

    Researchers retrospectively evaluated 93 consecutive high-risk myelodysplastic syndrome (MDS) patients undergoing allogenic-HSC transplantation in our institution, comparing discrepancies in clinical characteristics and outcomes between cases using Dec-intensified BUCY2 and traditional BUCY2 regimen.

    Abstract

    Hematopoietic Stem Cell Gene Therapy Ameliorates CNS Involvement in Murine Model of GM1-Gangliosidosis

    Investigators evaluated the therapeutic efficacy of ex vivo gene therapy targeting HSCs using a lentiviral vector to increase enzyme activity, reduce substrate accumulation, and improve astrocytosis and motor function.
