    Abstract

    IL-1β Stimulated Human Umbilical Cord Mesenchymal Stem Cells Ameliorate Rheumatoid Arthritis via Inducing Apoptosis of Fibroblast-Like Synoviocytes

    TRAIL receptor-Death receptor 4 (DR4), DR5, and lymphocyte function-associated antigen 1 ligand-intercellular adhesion molecule-1 were upregulated in IL-1β-stimulated human fibroblast-like synoviocytes-rheumatoid arthritis.

    Exosomes Derived from Human Umbilical Cord Mesenchymal Stem Cells Loaded with RVG-Lamp2b and Netrin-1 Promotes Schwann Cell Invasion and Migration

    Rabies virus glycoprotein (RVG)-Lamp2b and/or Netrin-1 were overexpressed in human umbilical cord MSCs to obtain exosomes modified with RVG-Lamp2b and/or loaded with Netrin-1.

    Exosomes Derived from LPS-Preconditioned Bone Marrow-Derived MSC Modulate Macrophage Plasticity to Promote Allograft Survival via the NF-κB/NLRP3 Signaling Pathway

    The exosomes were isolated from the supernatant of MSCs pretreated with lipopolysaccharide (LPS). LPS pre-Exo and rapamycin were injected via the tail vein into C57BL/6 mice allografted with BALB/c skin; graft survival was observed and evaluated.

    Mesenchymal Stromal Cells Confer Breast Cancer Doxorubicin Resistance by Producing Hyaluronan

    Scientists found that MSCs confer breast cancer resistance to doxorubicin by diminishing its intratumoral accumulation. Hyaluronan, a major extracellular matrix product of MSCs, was found to mediate the chemoresistant effect.

    Abstract

    Potential Impact of Mesenchymal Stem Cells on Nephrotoxicity Induced by Gamma Irradiation and Antiepileptic Drugs Cotherapy in Rats

    Researchers assessed the influence of bone marrow-derived MSCs on the nephrotoxicity induced by fractionated doses of gamma irradiation and the co-therapy of levetiracetam and oxcarbazepine in male rats.
