Nanotech makes paralyzed mice walk again

Posted on Saturday, May 05 2007 @ 16:27:19 CEST by


Scientists found a way to make paralyzed mice walk again with the help of nanotechnology:
Samuel Stupp has a bunch of mice that used to drag their hind legs behind them when they crawled around his Illinois lab, but they have miraculously regained at least partial use of their rear legs.

Astonishingly, their severed spinal cords have been repaired, at least partly, without surgery or drugs.

All it took was a simple injection of a liquid containing tiny molecular structures developed by Stupp and his colleagues at Northwestern University. Six weeks later, the mice were able to walk again. They don't have their former agility, but their injuries should have left them paralyzed for life.

Stupp is on the cutting edge of one of the most exciting fields in medical research: regenerative medicine. If he and others in the field are on the right track, one of these days tragic diseases like Parkinson's and Alzheimer's will be a thing of the past. And the crippled will walk again as the human body repairs itself in ways that it cannot do today.

Preliminary results with lab animals have been encouraging, but what works for mice and rats frequently does not work for humans. But if it does, medicine will enter a new era..
