    STAG2 Loss Rewires Oncogenic and Developmental Programs to Promote Metastasis in Ewing Sarcoma

    The core cohesin subunit STAG2 is recurrently mutated in Ewing sarcoma but its biological role is less clear. The authors demonstrated that cohesin complexes containing STAG2 occupied enhancer and polycomb repressive complex-marked regulatory regions.

    Bio-Instructive Hydrogel Expands the Paracrine Potency of Mesenchymal Stem Cells

    Scientists introduced a customizable collagen I-hyaluronic acid (COL-HA)-based hydrogel platform for the encapsulation of MSCs. Cells encapsulated within COL-HA showed a significant expansion of their secretory profile compared to MSCs cultured in standard 2D cell culture dishes or encapsulated in other hydrogels.

    NFAT Signaling in Human Mesenchymal Stromal Cells Affects Extracellular Matrix Remodeling and Anti-Fungal Immune Responses

    RNA-sequencing analysis of zymosan-treated MSCs showed that calcineurin-NFAT inhibition affected extracellular matrix genes, but not cytokine expression that was under the control of the NF-κB pathway.

    Osteogenic Differentiation of Human Mesenchymal Stromal Cells and Fibroblasts Differs Depending on Tissue Origin and Replicative Senescence

    To elucidate cell type-specific differences in the osteogenic differentiation potential and replicative senescence, scientists analyzed the impact of BMP and TGF-β signaling in adipose-derived stromal cells, fibroblasts, and dental pulp stromal cells.

    Human Umbilical Cord Mesenchymal Stem Cell Transfusion in Immune Non-Responders with AIDS: A Multicenter Randomized Controlled Trial

    The authors examined the safety and efficacy of human umbilical cord mesenchymal stem cell infusion for immune non-responder patients with chronic HIV-1 infection, who represented an unmet medical need even in the era of efficient antiretroviral therapy.

    Mesenchymal Stromal (Stem) Cell (MSC) Therapy Modulates miR-193b-5p Expression to Attenuate Sepsis-Induced Acute Lung Injury

    Investigators showed that treatment with MSCs decreased expression of host-derived miR-193b-5p and increased expression of its target gene, the tight junctional protein occludin, in lungs from septic mice.

    Abstract

    Senolytics Improve Bone Forming Potential of Bone Marrow Mesenchymal Stem Cells from Aged Mice

    By using a calvarial defect model, scientists showed that a senolytic cocktail improved the osteogenic capacity of aged bone marrow MSC both in vitro and in vivo.

    Abstract

    Integrated Diagnosis Based on Transcriptome Analysis in Suspected Pediatric Sarcomas

    To evaluate the potential utility of including RNA-sequencing in the diagnostic process, investigators performed RNA-sequencing in 47 patients with suspected pediatric sarcomas.
