Scientists made the paralyzed mice walk again. What about us?
The team first developed a signaling protein and inserted it into the brains of paralyzed animals, stimulating their nerve cells to regenerate, and has now shared the recipe for its creation with the entire scientific community. Spinal cord injuries are one of the most debilitating, damaged nerve fibers, or axons, are then unable to transmit signals between the brain and muscles, which often results in lower limb paralysis. What's worse, the condition is permanent because the nerve fibers cannot regenerate, or at least until recently.
