Spinal Cord Injury, Stem Cell and Nanotechnology

Scar tissues develop around a spinal cord injury, blocking neuron fibers that are supposed to repair the damaged site. Researchers from Northwestern University developed a nano-engineered gel that prevents the formation of scar tissue, allowing neuron stem cells to penetrate the inured site and grow nerve fibers. The gel also instructs stem cells to produce myelin, instead of producing scar tissues.

This technology has shown positive results with mice experiments. A mice that has spinal cord injury was able to use their hind legs in walking six weeks after being injected with the gel. Although not all treatments in mice works in humans, there is still a possibility that it could work.
