Why are stem cells so important to medical researchers?
They are the only potential treatment for Parkinson's and Alzheimer's disease
They may have the ability to target and destroy specific cancer cells
In most countries in the world, stem cell use is illegal
They may be used to create perfectly matched tissue to treat an individual disease or disorder
