Human stem cell treatment restores motor function in paralyzed rats

d in October 2004 in the European Journal of Neurosciences. In that study, significantly improved motor function, measured by a suppression of spastic movements and improved muscle tone, was shown in 40 to 50 percent of the animals tested. A post-mortem study of those animals showed a robust maturation of neurons and an increase in the expression of inhibitory neurotransmitters in the spinal cords of rats that received transplanted neuronal cells.

Current treatment for debilitating muscle spasticity is continuous systemic or spinal drug treatments using implanted pumps. These approaches, while effective to a degree, are often accompanied by side effects and eventual drug tolerance that lessens their efficacy.

“These research findings could offer great hope to people with spinal ischemic injury who suffer from resulting spasticity and rigidity,” said Marsala.
