Test Tube Brain Grown to Battle Alzheimer's

Stem cells in previous brain research

Stem cells in previous brain research

Yet, stem cells have also been used previously to develop lab-grown brain tissue. Researchers at Stanford University grew 2 forebrain circuits at a 16th of an inch across. They used only human skill cells and transformed them into pluripotent stem cells, using 4 genes in a petri dish. The pluripotent stem cells were then altered to become brain cells (neurons). The entire structure also included the cerebral cortex – a region of the brain that plays an important role in thought, memory, language, and attention. 

Scientists at Harvard University, on the other hand, followed through and grew a mini-organ of the human retina, which is the light-sensitive layer of tissue at the back of the eye.
