    CIC-Mediated Modulation of MAPK Signaling Opposes Receptor Tyrosine Kinase Inhibitor Response in Kinase-Addicted Sarcoma

    Researchers generated models of sarcomas bearing kinase fusions and assessed their response to molecularly targeted therapy. Immortalized, untransformed human MSCs, a putative cell-of-origin of sarcomas, were modified using CRISPR-Cas9 to harbor a RET chromosomal translocation.

    Antiphospholipid Antibodies Increase Endometrial Stromal Cell Decidualization, Senescence and Inflammation via TLR4, ROS and p38 MAP Kinase Signaling

    Antiphospholipid autoantibodies increased human endometrial stromal cell decidualization, senescence, and inflammation. The decidualization and inflammatory responses were partially mediated by toll-like receptor 4 (TLR4) and p38 MAP kinase.

    Abstract

    WNT/Beta-Catenin Signaling Interrupts a Senescence-Induction Cascade in Human Mesenchymal Stem Cells That Restricts Their Expansion

    Scientists showed that the signaling protein WNT3A counteracted the induction of paracrine senescence in cultured human adult MSCs.

    Abstract

    Nestin and NG2 Transgenes Reveal Two Populations of Perivascular Cells Stimulated by Photobiomodulation

    Investigators examined the early effect of photobiomodulation (PBM) in pericytes from experimentally injured pulp tissue. In vitro, PBM induced VEGF upregulation, improved dental pulp cells proliferation, and migration, and favored their mineralization potential.
