Zebrafish offers hope for spinal cord repair: US study

The Zebrafish, which can completely regenerate its severed spinal cord, might hold promise for research into tissue repair in humans, researchers said Thursday. Scientists are looking at one protein in particular that is key to this accomplishment in the fish, the researchers said. "This is one of nature's most remarkable feats of regeneration," said the study's senior investigator Kenneth Poss, a professor of cell biology at Duke University.
