BACKGROUND Ischemic stroke is a leading cause of disability and mortality worldwide, with limited therapeutic options for long-term recovery. Bone marrow-derived mesenchymal stem cell (BMSC)-derived exosomes have emerged as a promising cell-free therapy, but their efficacy is often constrained by poor homing efficiency...
