Scientists grow mini-brains in petri dishes

minibrain(CNN) A Harvard medical pioneer calls it “astounding” — an “incredible achievement” and a “quantum leap forward” in the battle against cancer, autism, Parkinson’s and Alzheimer’s.

What’s going on? Scientists at Ohio State University say they’ve figured out a way to grow the genetic equivalent of a nearly complete embryonic human brain.

Technically, they’re not quite “brains.” They’re called brain organoids — pieces of human tissue grown in petri dishes from skin cells.

These little blobs of tissue, 2-3 millimeters long, could help researchers test drugs and other treatments that may help prevent, fight and maybe even cure some of the most devastating disorders and diseases of our time.

In addition to Parkinson’s disease, autism and Alzheimer’s disease, they could also lead to unlocking the mysteries of schizophrenia, epilepsy, traumatic brain injuries and post-traumatic stress disorder. Millions of people suffer from all these disorders and diseases worldwide.

“The idea of taking skin cells, reverting them back to a basic stage of development and then teaching them how to turn into the cells that make up the brain is something we have been dreaming about for some time,” said CNN Chief Medical Correspondent Dr. Sanjay Gupta. “It is exponentially closer to reality now. Furthermore, the idea of using these ‘mini brains’ as a testing ground for therapies could help doctors figure out the best treatments for individual patients as opposed to the ‘one size fits all’ approach that is often used nowadays.”

Scientists have been making brain tissue organoids in the lab for less than a decade.

Japanese scientists were among the first to prompt cells from mice and humans to form “layered balls reminiscent” of a part of the brain called the cerebral cortex, according to the science journal, Nature. In 2011, Madeline Lancaster, a scientist a the Institute of Molecular Biotechnology in Vienna, was able to grow an embryonic brain…
