    Human Mesenchymal Stem Cell-Derived Miniature Joint System for Disease Modeling and Drug Testing

    A human MSC-derived miniature joint system was generated, in which engineered osteochondral complex, synovial-like fibrous tissue, and adipose tissue were integrated into a microfluidics-enabled bioreactor.

    Mesenchymal Stem Cells Empower T Cells in the Lymph Nodes via MCP-1/PD-L1 Axis

    The authors showed that the lymph nodes contain immunosupportive MSCs. They produced and secreted a high level of MCP-1 to promote T cell proliferation and differentiation, in contrast to bone marrow MSCs, which repressed T cell activation.

    Suppressive Effects of Umbilical Cord Mesenchymal Stem Cell-Derived Exosomal miR-15a-5p on the Progression of Cholangiocarcinoma by Inhibiting CHEK1 Expression

    Researchers identified the suppressing roles of exosomal miR-15a-5p from umbilical cord mesenchymal stem cells in the EMT and metastasis of cholangiocarcinoma.

    Oct4 Facilitates Chondrogenic Differentiation of Mesenchymal Stem Cells by Mediating CIP2A Expression

    The expression of Oct4 was elevated when the chondrogenic differentiation (CD) of cultured MSCs was induced. Silencing Oct4 damaged MSC growth and proliferation and decreased CD, indicated by decreased cartilage matrix formation and the expression of Col2a1, Col10a1, Acan, and Sox9.

    Abstract

    All-Trans Retinoic Acid Inhibits the Osteogenesis of Periodontal Ligament Stem Cells by Promoting IL-1β Production via NF-κB Signaling

    Investigators explored the effect of all-trans retinoic acid (ATRA) on the periodontal ligament stem cells (PDLSCs) osteogenic differentiation. PDLSCs were harvested from the periodontal membrane and treated with or without ATRA.

    Abstract

    Circulating Exosomes from Mice with LPS-Induced Bone Loss Inhibit Osteoblast Differentiation

    Scientists observed reduced osteoblast number and bone formation in lipopolysaccharide (LPS)-induced bone loss mice. Levels of circulating exosomes were increased by ~ twofold in LPS mice, and the expression of exosomal miRNAs was significantly changed.

    Various Detailed Characteristics of a New Enhanced Neurotrophic Factor Secreting Rat Derived Bone Marrow Mesenchymal Stem Cells and Its Preliminary Application in Rat Models of Ischemic Stroke

    The authors established some important characteristics that can be used to distinguish between MSC-NTF and MSCs: different multi-factor secretion ability and secretion characteristics, immunogenicity, three-line differentiation ability, stemness, etc.

    Abstract

    Gamma-Glutamyltransferase of Helicobacter pylori Alters the Proliferation, Migration, and Pluripotency of Mesenchymal Stem Cells by Affecting Metabolism and Methylation Status

    A gamma-glutamyltransferase knockout Helicobacter. pylori strain was constructed, and downstream histone H3K9 and H3K27 methylation and the PI3K/AKT signaling pathway of alpha-ketoglutarate were detected using Western blotting. The biological characteristics of MSCs were also examined.

    Human Umbilical Cord Blood Mesenchymal Stem Cells as a Potential Therapy for Schistosomal Hepatic Fibrosis: An Experimental Study

    Researchers assessed the effect of human umbilical cord blood mesenchymal stem cells transplantation on schistosomal hepatic fibrosis in mice.
