Scientist: We’ve grown a human ‘mini brain’

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.
