In the first clinical study of its kind, researchers at Tokyo's Keio Unviersity have developed a stem cell treatment that allowed a paralyzed man to stand on his own again following a spinal cord injury. As Japanese newspaper The Asahi Shimbun reports, the man is now learning how to walk. The stem cell treatment involved the injection of roughly two million reprogrammed or induced pluripotent stem (iPS) cells, which are created by turning adult cells back into an embryonic-like state. The researchers turned these cells into neural precursor cells in a lab and then injected them into each patient's injury […]
