| operation spinal cord regeneration: patterning information residing in extracellular matrix glycosaminoglycans. | spinal cord injuries are devastating, with many complications beyond paralysis and loss of sensory function. although spinal cord regeneration can revolutionize treatment for spinal cord injuries, the goal has not yet been achieved. the regenerative mechanism of axolotls demonstrates that the regeneration is a repeat of developmental process that all animals have all the genes, but axolotls have both the genes and the patterning information to do it at the adult stage. | 2020 | 31944630 |
