Genetic Parkinson's disease brain cells made in lab

Scientists in the US have successfully made human brain cells in the lab that are an exact replica of genetically caused Parkinson's disease.

The breakthrough means they can now see exactly how mutations in the parkin gene cause the disease in an estimated one in 10 patients with Parkinson's.

And it offers a realistic model to test new treatments on - a hurdle that has blighted research efforts until now.     Full Read
