It not only looks like the developing brain, its diverse cell types express nearly all genes like a brain, we’ve struggled for a long time trying to solve complex brain disease problems that cause tremendous pain and suffering. The power of this brain model bodes very well for human health because it gives us better and more relevant options to test and develop therapeutics other than rodents. Rene Anand, who began his quest four years ago, studies the association between nicotinic receptors and central nervous system disorders. He’s hopeful that the lab-grown brain will provide ethical and more rapid and accurate testing of experimental drugs before the clinical trial stage.
