In every case where embryonic stem cells have been tested in humans, it has resulted in disaster. In one case, the injection of human embryonic stem cells to eliminate a tumor caused the unmanageable eruption of multiple additional tumors. In another case, the injection of human embryonic stem cells to cure or reduce the manifestation of Parkinson’s disease caused the study subjects to go into uncontrollable seizures.
With the exponentially increasing number of successful applications of ADULT stem cells, there is no reason why embryonic stem cells should be used for anything. Embryonic stem cells are a waste of money and other valuable research resources.
