    TOP STORY

    Vascular Regeneration and Skeletal Muscle Repair Induced by Long-Term Exposure to SDF-1α Derived from Engineered Mesenchymal Stem Cells after Hindlimb Ischemia

    The authors investigated genetically engineered MSCs derived from human bone marrow that continuously secrete stromal-derived factor-1α (SDF1α) .

    Short-Term Assays for Mesenchymal Stromal Cell Immunosuppression of T-Lymphocytes

    Three potential assays were examined—assays of apoptosis focusing on caspase activation, assays of phosphatidyl serine externalization on peripheral blood mononuclear cells, and measurement of tumor necrosis factor alpha levels using rapid ELISA methods.

    Circ_0114581 Promotes Osteogenic Differentiation of BMSCs via the MiR-155-5p/HNRNPA3 Axis

    A competing endogenous RNA regulatory network was obtained through the application of osteoporosis-related high throughput data sets.

    Abstract

    Serial Passaging Affects Stromal Cell Mechanosensitivity on Hyaluronic Acid Hydrogels

    Researchers leveraged a methacrylated hyaluronic acid hydrogel platform to study stromal cell mechanotransduction. Hydrogels were first formed through thiol-Michael addition to model normal soft tissue stiffness.

    Abstract

    Chemical Hypoxic Preconditioning Improves Survival and Proliferation of Mesenchymal Stem Cells

    Investigators used proteomic analysis to explore the molecules that may contribute to the survival and proliferation of hypoxic preconditioned MSCs.
    [Applied Biochemistry and Biotechnology]

    Abstract

    Endothelial Cell-Derived Lactate Triggers Bone Mesenchymal Stem Cell Histone Lactylation to Attenuate Osteoporosis

    Researchers found that ovariectomized mice exhibited reduced blood vessel density in the bone and reduced expression of the endothelial glycolytic regulator pyruvate kinase M2.

    The Critical Role of The Piezo1/β-catenin/ATF4 Axis on The Stemness of Gli1+ BMSCs during Simulated Microgravity-Induced Bone Loss

    By single-cell RNA sequencing, bone marrow-derived MSCs were the most downregulated cell cluster, and coincidentally, Piezo1 expression was mostly enriched in those cells, and was substantially downregulated by unloading.

    Engineered Mesenchymal Stem Cell Exosomes Loaded with miR-34c-5p Selectively Promote Eradication of Acute Myeloid Leukemia Stem Cells

    The authors employed simultaneous two-step modifications to engineer MSCs and MSC-derived exosomes to create exosomes overexpressing the fused protein lysosome-associated membrane protein 2-interleukin 3 and hematopoietic cell E-selectin/L-selectin ligand.

    Antler Stem Cell Exosomes Alleviate Pulmonary Fibrosis via Inhibiting Recruitment of Monocyte Macrophage, Rather than Polarization of M2 Macrophages in Mice

    Researchers found that administration of antler stem cells improved the survival rate of pulmonary fibrosis mice and reduced lung fibrosis, collagen deposition, and myofibroblast differentiation.

    Ginsenoside RG1-Induced Mesenchymal Stem Cells Alleviate Diabetic Cardiomyopathy through Secreting Exosomal circNOTCH1 to Promote Macrophage M2 Polarization

    A diabetic cardiomyopathy mouse model was constructed, and the effects of ginsenoside RG1-induced MSCs on myocardial function and fibrosis in diabetic mice were evaluated.
