TOP STORYResearchers assessed the role of mitochondrial dysfunction in the impaired immunomodulatory properties of MSCs from atherosclerosis (ATH) patients. An impaired mitochondrial function of ATH-MSCs underlies their altered secretome, and reduced immunopotency. [Circ Res] Abstract | |

PUBLICATIONS(Ranked by impact factor of the journal)IN VITROScientists investigated the comparative hepatogenic potential of human bone marrow stem cells with stem cells derived from human dental pulp, apical papilla and follicle during this study. Hepatogenic potential of stem cells were assessed by functional assays at both genetic and protein level. [Sci Rep] Full Article Investigators performed whole genome sequencing of two peripheral blood-derived MSC lines at various passages. [Sci Rep] Full Article miRNA Profiling of Nurown®: Mesenchymal Stem Cells Secreting Neurotrophic Factors Researchers determined whether the miRNA profile could provide a tool for MSC-neurotrophic factor cell characterization and to distinguish them from the matched MSC from which they are derived. [Stem Cell Res Ther] Full Article | Press Release Th authors report that differentiation of human mesenchymal stem cells into osteoblasts or adipocytes results in extensive remodeling of the plasma membrane, producing cell-specific membrane compositions and biophysical properties. [Sci Adv] Full Article | Press Release Coculture of Meniscus Cells and Mesenchymal Stem Cells in Simulated Microgravity Scientists investigated the effect of simulated microgravity on cocultures of primary human meniscus cells and adipose-derived MSCs. Simulated microgravity significantly enhanced cartilaginous matrix formation in cocultures of primary meniscus cells and adipose-derived MSCs. [npj Microgravity] Full Article IN VIVOTGFβ3 Recruits Endogenous Mesenchymal Stem Cells to Initiate Bone Regeneration In vivo, a 2-mm FVB/N mouse femur defect model was used to evaluate chemokine secretion, endogenous cell homing, and bone regeneration induced by scaffolds loading 1 μg transforming growth factor beta-3 (TGFβ3) through qPCR, immunofluorescent staining, immunohistochemical analysis, and Micro-CT, compared to the vehicle group. [Stem Cell Res Ther] Full Article Scientists examined the role of the α-isoform of protein phosphatase 2A catalytic subunit (PP2A Cα) in in vivo bone formation by generating transgenic mice, in which the dominant negative form of PP2A Cα was specifically expressed in osteoblasts. [Mol Cell Endocrinol] Abstract | Graphical Abstract A combined strategy was applied to evaluate bone marrow-derived MSCs (BMSCs) homing to the rat model of liver cirrhosis induced by common bile duct ligation: A pretreatment delivery of resveratrol into the cirrhotic liver, and a transplantation of ex vivo BMSC preconditioning with stromal cell-derived factor-1α (SDF-1α). [J Cell Biochem] Abstract Investigators assessed coculture of allogenic decalcified bone matrix (DBM) and bone marrow mesenchymal stem cells (BMSCs) in the knee joint cavity of rabbits for cartilage tissue engineering.

REVIEWSThe authors focus on effectiveness of neurotrophic growth factors, including erythropoietin, brain-derived neurotrophic factor, vascular endothelial growth factor, glial-derived neurotrophic factor, and MSC therapy, in both experimental neonatal stroke studies and first clinical trials for neonatal ischemic brain injury. [Pediatr Res] Abstract Researchers focus on recent investigations that elucidate the specifically regulated paracrine mechanisms of MSCs by injury type and discuss potential strategies to enhance paracrine potency, and thus therapeutic efficacy, of transplanted MSCs, including determining the appropriate source and preconditioning strategy for MSCs and the route and timing of their administration.

POLICY NEWSGraduate Students Face Alarming Tax Hike The last thing that graduate students need is a tax hike. But that is what many would face under a clause in the federal-tax-reform bill passed by the US House of Representatives. It will need to be reconciled with the Senate’s tax-reform bill (which retains many existing student tax benefits), and signed by the president. [Nature News] Editorial UK Government Appoints Next Chief Scientific Adviser Patrick Vallance, president of research and development at the pharmaceutical giant GlaxoSmithKline, has been appointed as chief scientific adviser, the UK government announced.
