Super exciting research. Apparently, there is a lot going on in fish that I wish would happen with humans. Regeneration of the spinal cord also occurs in possibly one of the coolest fish in the world, the black ghost knife fish, which not only regenerates the spinal cord, but swims using a single fin under them, http://www.kurzweilai.net/scientists-find-key-protein-for-spinal-cord-repair-in-zebrafish
This study, if possible in humans, would allow an injection to someone with a spinal cord injury, and allow the reconnection of neurons, and therefore function to the cells “south” or caudal to the damage site. That means you could reverse paralysis and all the nastiness that goes along with it. Of all research that needs funding, this one is a no brainer. Literally, since the brain isn’t necessarily involved in the process!
