Has embryonic stem cell research yielded results anywhere in the world? On the other hand, adult stem cell research has yielded several treatments for various diseases.
Certainly, it yields tumors.
embryonic stem cells have produced results - the growth of uncontrollable tumors. Apparently there is not a switch "off" for embroyonic stem cells as there is such a switch in adult stem cells. MJF would like to have tumors added to his plight? He is either stupid or a liar with this ad.
