“‘mini-brains’ … are growing their own blood vessels”



Lab-made mini-brains are sprouting their own blood vessels—Michael Irving, New Atlas; from the Abbe Normal dept.

In 2015, scientists at Brown University developed “mini-brains,” models of living brains created from 3D cultures of neural cells. Like organs-on-chips, these models could help reduce our reliance on animal testing in the search for new treatments and drugs, and make early results more accurate. Now, the researchers have discovered something new about these mini-brains: the neural cells are growing their own blood vessels too, opening the door for better studies of stroke, Alzheimer’s and concussion.
