    Bone marrow Adipoq-lineage progenitors are a major cellular source of M-CSF that dominates bone marrow macrophage development, osteoclastogenesis, and bone mass

    Kazuki Inoue, Yongli Qin ... Baohong Zhao
    Identification of bone marrow Adipoq-lineage progenitors as a novel and major cellular source of M-CSF in mice and humans, which controls bone marrow macrophage development, osteoclastogenesis, and bone mass in physiological and pathological conditions.

    Lipolysis of bone marrow adipocytes is required to fuel bone and the marrow niche during energy deficits

    Ziru Li, Emily Bowers ... Ormond A MacDougald
    Bone marrow adipocyte lipolysis is required for maintaining bone mass under conditions of energy deficiency and is necessary for myelopoiesis following caloric restriction and irradiation.

    In vivo generation of bone marrow from embryonic stem cells in interspecies chimeras

    Bingqiang Wen, Guolun Wang ... Vladimir V Kalinichenko
    Blastocyst complementation of rat embryos with donor mouse embryonic stem cells was used to simultaneously produce multiple, donor-derived hematopoietic and stromal cells in the interspecies bone marrow that exhibited normal gene expression signatures, cell surface markers, and functional characteristics.

    Identification of phenotypically, functionally, and anatomically distinct stromal niche populations in human bone marrow based on single-cell RNA sequencing

    Hongzhe Li, Sandro Bräunig ... Stefan Scheding
    Single-cell transcriptomic profiling of human bone marrow non-hematopoietic cells provides the basis for a comprehensive understanding of the cellular complexity of the hematopoietic stem cell (HSC) microenvironment and the intricate stroma-hematopoiesis crosstalk mechanisms.

    Reprogramming of bone marrow myeloid progenitor cells in patients with severe coronary artery disease

    Marlies P Noz, Siroon Bekkering ... Niels P Riksen
    In patients with coronary artery disease, bone marrow myeloid progenitor cells are reprogrammed towards myeloid skewing and inflammatory activation.

    FGF2-FGFR1 signaling regulates release of Leukemia-Protective exosomes from bone marrow stromal cells

    Nathalie Javidi-Sharifi, Jacqueline Martinez ... Elie Traer
    Inhibition of FGF2-FGFR1 signaling in bone marrow stroma attenuates secretion of FGF2-laden exosomes and subsequent protection of leukemia cells.
