Researchers at UCSD succeeded in reprogramming skin cells from an 86-year-old man to neurons that grew in rats with spinal cord injuries.
The reprogrammed cells were grafted into rats two weeks after their injury.
Three months later, the neurons had matured, and there was nerve growth across their spinal cords extending into their brains.
While the rats did not regain function of their limbs, scientists say they're working to translate these results to humans by using their own grafted stem cells.
