Paralysis is the result of a spinal cord injury. Most spinal cord injuries cannot be treated by existing therapies, as damaged nerve fibers in the spinal cord do not regenerate and heal. Recently, a study showed the cause of non-regeneration of nerve cells, which gives researches an idea on how to develop new technologies that can eventually cure spinal cord injuries. Researches saw that a molecule called netrin-1 repels stem cells from the injured site, preventing stem cells to reach and repair the injury. Netrin-1 provides signals to nerve cells for it to reach its target.
Another recent research on mice used nanotechnology to treat spinal cord injuries.
