PUBLICATIONS(Ranked by impact factor of the journal)IN VITROPotency Analysis of Mesenchymal Stromal Cells Using a Combinatorial Assay Matrix Approach The authors tested two assay systems to measure the potency of MSCs derived from human subjects: MSC secretome analysis and a quantitative RNA-based array for genes specific to immunomodulatory and homing properties of MSCs. [Cell Rep] Full Article | Graphical Abstract From a heterogeneous placental single-cell suspension, a directly flow-sorted CD45−CD34+CD144+CD31Lo population uniquely differentiated into both endothelial and mesenchymal colonies in limiting dilution culture assays. [Stem Cell Reports] Full Article | Press Release | Graphical Abstract Scientists investigated the effects of aging on human bone-derived MSCs expressing CD271 and SSEA-4 (double-positive MSCs [DPMSCs]). The percentages of DPMSCs in bone tissue decreased significantly with age. [Stem Cell Reports] Full Article | Graphical Abstract Researchers investigated the potential of magnesium to regulate macrophage polarization and macrophage-induced inflammation with or without lipopolysaccharide and interferon-γ activation and further elucidated whether these effects impact the inhibitory functions of activated macrophage-induced inflammation on cartilage regeneration. [Sci Rep] Full Article Investigators demonstrated that clusterin mRNA expression and protein secretion in conditioned medium increased during adipocyte differentiation and decreased during osteoblast differentiation of mouse bone marrow-derived skeletal stem cells. [Bone] Abstract PD-1 Is Required to Maintain Stem Cell Properties in Human Dental Pulp Stem Cells Scientists showed that neural crest-derived MSCs from dental pulp (MSC-DP), but not MSCs from bone marrow, expressed PD-1. Knocking down PD-1 expression in MSC-DP resulted in a significantly reduced capacity for cell proliferation and accelerated multipotential differentiation. [Differentiation] Abstract IN VIVOResearchers studied the immunological response to MSC treatment in 16 aGvHD patients by assessing lymphocyte profiles and three proposed aGvHD serum markers during the MSC treatment. [Mol Ther Methods Clin Dev] Abstract The authors investigated the effects of bone marrow MSCs and TNF-α-stimulated gene 6 protein (TSG-6) on intervertebral disc degeneration and explored the possible underlying mechanisms in vitro and in vivo. [Lab Invest] Abstract Investigators explored the effects of chaihulonggumulitang on acute myocardial infarction and anxiety in vivo and in vitro. They also tested its effects in promoting bone marrow MSCs mobilization and alleviating inflammation. [Sci Rep] Full Article Researchers evaluated the immunomodulatory effects of MSCs from human embryonic stem cells (hESCs) on asthma. The hESC-MSCs were analyzed for the expression of stem cell surface markers by flow cytometry, their differentiation potentials were analyzed using in vitro trilineage differentiation methods. hESC-MSCs were transplanted into the murine model with ovalbumin-induced airway allergic inflammation.

REVIEWSEngineering Stem and Stromal Cell Therapies for Musculoskeletal Tissue Repair The authors present recent clinical advances where stem cells and stromal cells have been used to stimulate musculoskeletal tissue repair, including delivery strategies to improve cell viability and retention. [Cell Stem Cell] Abstract Mesenchymal Stem Cells in Multiple Myeloma: A Therapeutical Tool or Target? Researchers focus on the current understanding of the biological role of MSCs in multiple myeloma as well as the potential utility of MSC-based therapies in this malignancy.

INDUSTRY NEWSCollPlant announced that it is part of ReMDO’s advanced biomanufacturing initiative for the development of a universal BioInk with tunable properties for 3D bioprinting of tissues and organs. [CollPlant (PR Newswire Association LLC)] Press Release Mesoblast Limited announced that the Phase III trial of its allogeneic mesenchymal stem cell product candidate MSC-100-IV in children with steroid refractory acute Graft versus Host Disease has successfully met the primary endpoint of Day 28 overall response rate.

POLICY NEWSMerkel Makes a Surprise Pick for German Research Minister German Chancellor Angela Merkel isn’t known for her political surprises. But she managed a big one when she tapped Anja Karliczek, a 46-year-old lawmaker little known outside of party circles, as Germany’s next minister for education and research. [ScienceInsider] Editorial Florida Residents Could Soon Get the Power to Alter Science Classes Policymakers in the United States are pushing to give the public more power to influence what educators teach students. Florida’s legislature started considering two related bills that, if enacted, would let residents recommend which instructional materials teachers in their school district use in their classrooms. [Nature News] Editorial One of the Most Powerful Science Policy Jobs in Brussels Changes Hands It’s the end of an era at the European Commission’s research department: The most powerful civil servant in Brussels’s science policy circles, Director-General for Research and Innovation Robert-Jan Smits, is leaving his post.
