Safety and potential efficacy of expanded mesenchymal stromal cells of bone marrow and umbilical cord origins in patients with chronic spinal cord injuries: a phase I/II study.

Background Aims: Spinal cord injury (SCI) affects patients' physical, psychological, and social well-being. Presently, treatment modalities for chronic SCI have restricted clinical effectiveness. Mesenchymal stromal cells (MSCs) demonstrate promise in addressing nervous tissue damage.
