“Mini brains,” or brain organoids, the latest development in stem cell technology, are organized 3D cell structures made up of different brain cells, which resemble the complexity of the human brain. Human stem cells can be grown into brain organoids in 40 days, offering neuroscientists an unprecedented opportunity to more accurately model human brain development and disease. Read More
