Rise Of The Organoids: Miniature Human Brain Most Complete To Date

Posted by in categories: biotech/medical, health, life extension, neuroscience

As regenerative medicine expands, our ability to engineer organs is growing with it. Researchers can now grow a number of so called ‘organoids’ — mini-organs which can teach us more about developmental biology and enable vastly improved testing. In the latest addition to the bunch, a team from Ohio State University has successfully engineered the most complete model yet of a human brain, with a similar maturity to a 5 week old fetus.

Containing 99% of the genes present in the human fetal brain, and about the size of an eraser, the organoid was developed from transformed adult human skin. This method could allow more ethical and precise clinical trials, both speeding up and enabling more rigorous, personalized testing. As animal testing frequently fails to predict varied human responses, these organoid models offer an alternative approach which could revolutionize clinical trial methodology.

“It not only looks like the developing brain, its diverse cell types express nearly all genes like a brain. We’ve struggled for a long time trying to solve complex brain disease problems that cause tremendous pain and suffering. The power of this brain model bodes very well for human health because it gives us better and more relevant options to test and develop therapeutics other than rodents.”
