Rat brain injuries are ‘plugged up’ in world’s first experiment using lab-grown human mini-brains.

A new study shows that laboratory-grown miniature models of the wrinkled surface of the human brain can be used to repair injuries in the brains of living rats, thereby repairing broken connections in rodents’ sensory processing systems. One day, such mini-brains — known as brain organoids — could potentially also be used to repair the brains of human patients, the study authors suggest.

“I see this as the first step in developing a new strategy to repair the disease Brain,” called dr Han Chiao Isaac Chen (opens in new tab)senior author of the study and assistant professor of neurosurgery at the University of Pennsylvania Perelman School of Medicine.
