A group of scientists in Israel are researching how to help paralyzed people walk again. They are using human stem cells to repair the spinal cords of mice. The results sound like a miracle. The researchers put human stem cells in mice with severed spinal cords. About six weeks after the surgery, some of the mice were able to walk. Shulamit Levenberg is a researcher at the Israel Institute of Technology. She explains how she and other researchers were able to create spinal cord recovery. In this project we managed to induce spinal cord regeneration following complete injury to the spinal cord, and this was to the extent where the animal that was totally paralyzed started to walk again and also regained sensory perception. And this was really amazing, to see the animals walk after two, three weeks.”
