Mice With Human Brain Cells Produced

U.S. researchers have produced laboratory mice with human brain cells, marking a potential step toward developing treatments for human brain disease such as Alzheimer’s but promising to fuel fresh debate over bioengineering.

The research was done at California biotechnology company StemCells Inc.

“We are not re-creating a human brain. We’re really just trying to understand how these stem cells can function and how they can be used in the treatment of specific diseases,” said Ann Tsukamoto, vice president of scientific operations at StemCells.
