Nifty stem-cell engineering sheds light on Parkinson's disease

Researchers at the University at Buffalo may have taken a significant step toward unraveling the way Parkinson's disease assails the human nervous system--thanks in part to a nifty bit of stem-cell engineering.

Scientists led by physiologist Jian Feng took skin cells from healthy control subjects and people with a particular type of Parkinson's disease and transformed them into a type of primordial cell--technically, an "induced pluripotent stem cell." Such iPS cells, as they're known, can be coaxed into developing as almost any type of cell in the body.

Here, they turned into brain cells. … Read more
