An innovative, biodegradable nerve guide can regenerate damaged nerves without the need for stem cells or donor nerves.
The nerve guide created by the team from the University of Pittsburg consists of a polymer tube filled with a protein that promotes the regeneration of long sections of nerves. The protein, which was also used in a Parkinson’s trial, releases slowly over time, encouraging the growth of new nerves with the need for transplants. In tests on monkeys, the nerve guide supported enough cell growth to bridge a two-inch gap, and performed comparable too if not better than a nerve graft.
