miR-31 from Mesenchymal Stem Cell-Derived Extracellular Vesicles Alleviates Intervertebral Disc Degeneration by Inhibiting NFAT5 and Upregulating the Wnt/β-Catenin Pathway

Figure 9

Schematic diagram of the mechanism by which miR-31 in hBMSC-EVs affects IDD. hBMSC-EVs transferred miR-31 to NPCs where miR-31 targets NFAT5 and reduces the expression of NFAT5 and activates the Wnt/β-catenin pathway, thus promoting the proliferation of NPCs, inhibiting their apoptosis, and reducing the release of cellular inflammatory factors, ultimately alleviating IDD in mice.
