Researchers find possible path to regeneration of injured spinal cords

It’s a long way from experiments with lab mice to clinical treatment of humans, and as a Georgia trial attorney in Atlanta, I only represent human spinal cord injury survivors.

However, it is interesting to observe progress in animal experiments that may someday carry over to treatment of humans.

According to an article published in Nature Neuroscience, researchers from UC Irvine, UC San Diego and Harvard recently announced they had induced nerve regeneration in mice with severe spinal cord injury.  They deleted an enzyme called PTEN (a phosphatase and tensin homolog), which controls a  molecular pathway that regulates cell growth. PTEN activity is low during development but turns on when growth is completed. Previously, researchers showed they could block PTEN in mice to regenerate nerve connections from the eye to the brain after optic nerve damage. The new research gives some degree of hope that such nerve regeneration could take place in the injured spinal cord.
