Important pieces of the puzzle to understand what drives diseases such as Alzheimer's and Parkinson's are still missing today. One crucial obstacle for researchers is that it is impossible to examine a living brain cell in someone who is affected by the disease. With the help of a new method for cell conversion, researchers have found a way to produce diseased, aging brain cells on a large scale in a cell culture dish.
