Nerve Regeneration Possible in Spinal Cord Injury

Posted on 2009-11-04 06:00:00 in Regenerative Medicine |

With more than 10,000 new spinal cord injuries (SCI) occurring annually in the United States, scientists such as Mark H. Tuszynski, from the University of California San Diego School of Medicine (USA), have been exploring ways to regenerate the spinal cord nerves. In an animal model of SCI, the researchers were able to successfully regenerate adult spinal cord axons into and beyond an injury site in the cervical spinal cord. Treatment was begun at time periods ranging from 6 weeks to 15 months after the original injury occurred, suggesting for the first time that “regeneration is achievable at unprecedented postinjury time points.”
