German researchers have found a way to regrow nerves of mice that could not walk, permitting them to walk again. The mice had been paralyzed because of injuries to their spinal cords. The researchers used a designer protein injected into the brain. It recreates a link in the brain that scientists had always believed could not be repaired once broken. Spinal cord injuries in humans are often caused by sports or car accidents. The injuries leave them paralyzed because some of the nerves that move information between muscles and the brain are not able to grow back. The researchers from Ruhr University Bochum were able to cause the paralyzed mice’s nerve cells to grow back using the designer protein.
