Researchers regrow damaged nerves with polymer and protein

Researchers regrow damaged nerves with polymer and protein: University of Pittsburgh School of Medicine researchers have created a biodegradable nerve guide—a polymer tube—filled with growth-promoting protein that can regenerate long sections of damaged nerves, without the need for transplanting stem cells or a donor nerve.So far, the technology has been tested in monkeys, and the results of those experiments appeared today in Science Translational Medicine.
