Dear Commons Community,

Scientists at Ohio State University say they’ve grown the first near-complete human brain in a lab.  As reported in The Huffington Post:

“The brain organoid, if licensed for commercial lab use, could help speed research for neurological diseases and disorders, like Alzheimer’s and autism, Rene Anand, an Ohio State professor who worked on the project, said in a statement Tuesday,

“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,” Anand said.

The brain, engineered from adult human skin cells and grown in a dish for 15 weeks, is about the size of a pencil eraser, according to the university. It has the maturity of a 5-week-old fetal brain, and contains 99 percent of the genes in a fully developed human fetal brain.

“If we let it go to 16 or 20 weeks, that might complete it, filling in that 1 percent of missing genes,” Anand said. “We don’t know yet.”

Other researchers in the field were skeptical. Anand’s claims haven’t been reviewed by peers. Instead, the feat was announced at the 2015 Military Health System Research Symposium in Ft. Lauderdale, Florida. (Anand’s team says the brain could have military research implications for traumatic brain injury and post-traumatic stress disorder).

“When someone makes such an extraordinary claim as this, you have to be cautious until they are willing to reveal their data,” Zameel Cader, a consultant neurologist at the John Radcliffe Hospital, Oxford, told The Guardian.

Earlier this year, Anand and colleague Susan McKay created an Ohio-based startup with the goal of commercializing the brain organoid platform. As The Guardian notes, Anand has not published details of his brain model due to a pending patent. “

While we congratulate Professor Anand and his team, I believe there will be a lot of ethical questions looming for this type of research.
