Researchers at UC San Diego may have just figured out a way to treat spinal cord injuries by training the nerves to regenerate themselves properly. They've proven that by combining the use of biological chemicals called neurotrophia-3 (NT-3) with a 'cell bridge', the area of injury and stimulating the body's regenerative genes, the severed spinal cord nerves will regenerate. 

While this is fantastic, it doesn't mean that those injuries would be completely healed. Professor Mark Tuszynski explains:

While our findings are very encouraging... they also highlight the complexity of restoring function in the injured spinal cord.
