• Nerve cells can be grown from stem cells in Petri dishes, enabling scientists to research diseases. Previously, it was only possible to create a few dozen different types of nerve cell.
• Using a new method, researchers have now managed to produce over 400 different types of nerve cell.
• Cell culture models with cells of this kind are of interest for research into diseases such as Alzheimer’s and Parkinson’s, as well as for testing new drugs in pharmaceutical research.
