Scientists Regenerate Spinal Nerves

This is hopeful: For the first time scientists have induced what they call “robust regeneration” of damaged nerve tissues in spinal cord sites—a breakthrough that could eventually repair muscle function in people paralyzed from spinal-cord injuries. Doctors repaired the cells by deleting an enzyme that prevents cell growth. "Until now, such nerve regeneration has been impossible in the spinal cord," says one doctor. "Paralysis and loss of function from spinal-cord injury has been considered untreatable, but our discovery points the way toward a pathway to develop a therapy to induce regeneration of nerve connections following spinal-cord injury in people."
