In a medical breakthrough, Japanese scientists at Keio University have successfully helped a paralyzed man stand again using a pioneering stem cell therapy derived from induced pluripotent stem cells (iPSCs). The clinical trial, involving four patients with severe spinal cord injuries, marks the world's first successful use of iPSC-based neural stem cells for spinal repair. One patient has regained enough strength to stand unaided and begin walking practice, showing new hope for millions affected by paralysis. While still in early stages, the research signals a major step toward restoring mobility through regenerative medicine.
