... would move from one class to another." One of the advantages of using ES cells over other types of stem cells is to reduce immunoreactivity. "Because ES cells have fewer surface antigens, they're unlikely to trigger immunoreaction, in which the body rejects the foreign intruder," Morgan explains.
