Parkinson's disease is caused by the gradual loss of dopamine-producing cells in the brain. Dopamine is a brain chemical that, among other things, helps regulate movement and emotional responses.
There is currently no cure for Parkinson's disease, but there are drugs that can slow it down, and deep brain stimulation can alleviate symptoms of Parkinson's in certain patients.
Human embryonic stem cells - precursor cells that have the potential to become any cell of the body - are a promising source of new dopamine cells, but they have proved difficult to harness for this purpose.
A breakthrough study from Lund University in Sweden shows it is possible to get human embryonic stem cells to produce a new generation of dopamine cells that behave like native dopamine cells when transplanted into the brains of rats.
