Summary:

Researchers at the University of Rochester Medical Center in New York reported that injecting human embryonic stem cells into the brains of Parkinson's disease patients may cause tumors to form. The researchers said human stem cells injected into rat brains turned into cells that looked like early tumors. The idea behind brain cell transplants is to replace the dead cells.

Commentary: Hopefully researchers will figure out how to eliminate the tumors that formed from this treatment and be able to eventually test it in humans with Parkinson's Disease and treat them successfully.
