We've seen beating heart tissue, windpipes and bladders all grown from stem cells. Now researchers have taken another important step forward by growing mini brains from these programmable cells. They're not actually functioning brains -- in the same way that a car with the engine on its roof or wheels on its hood isn't a drivable vehicle -- but the parts are there, and that's an important scientific advancement, according to Juergen Knoblich, senior author of a new study on using stem cells to grow brain tissue. Scientists have created what they are calling "cerebral organoids" using stem cells. These pea-sized structures are made of human brain tissue, and they can help researchers explore important questions about brain development and disorders that occur during these first stages of life.
