Functionally Enhanced Placenta-Derived Mesenchymal Stem Cells Inhibit Adipogenesis in Orbital Fibroblasts With Graves’ Ophthalmopathy

    Jae Yeon Kim, Sohae Park, Hyunjung Lee, Helen Lew, Gi Jin Kim
    The study investigated the effects of PRL-1-overexpressing placenta-derived mesenchymal stem cells (PD-MSCs PRL-1) on adipogenesis in orbital fibroblasts (OFs) from patients with Graves’ ophthalmopathy (GO). The research found that PD-MSCs PRL-1 significantly reduced lipid accumulation and decreased the expression of adipogenic markers in OFs compared to naïve cells. This effect was linked to the secretion of insulin-like growth factor-binding proteins (IGFBPs) by PD-MSCs PRL-1, which downregulated the PI3K/AKT/mTOR signaling pathway and upregulated phosphorylated FAK through integrin interactions. These findings suggested that functionally enhanced PD-MSCs could offer a novel therapeutic approach for treating degenerative diseases like GO.
