Exosomes derived from menstrual blood-derived mesenchymal stem cells and treadmill training restore motor function following SCI by activating PI3K/Akt pathway

MenSCs-Exo combined with WSTT synergistically enhances motor recovery after SCI by promoting tissue repair, reducing fibrosis, and activating the PI3K/Akt pathway. This cell-free therapy paired with rehabilitation exercise offers a novel strategy for SCI treatment.
