Wnt5a‐Induced Exosomes From Bone Marrow Mesenchymal Stem Cells Promote Spinal Cord Injury Repair by Modulating Immune Cell Phenotypes and Alleviating Neuroinflammation via the <scp>NF</scp> ‐ <scp>κB</scp> Pathway

Collectively, these findings indicate that Wnt5a enhances the neuroregenerative potential of BMSC-Exos by modulating immune responses and suppressing neuroinflammation, likely through inhibiting the NF-κB signaling pathway.
