This article is short but here's the gist, I especially like the language of the last paragraph...the link follows:

"When stem cells from the nose of Parkinson's patients were cultured and injected into the damaged area the rats re-acquired the ability to run in a straight line.

"All animals transplanted with the human cells had a dramatic reduction in the rate of rotation within just three weeks."

He said the discovery meant they were on the verge to finding a cure for Parkinson's, a debilitating disease which includes loss of muscle control caused by the degeneration of cells that produce the essential chemical dopamine in the brain.

The study was published yesterday in the journal Stem Cells"
