Just go to the source to produce compatible cells to help people with devastating diseases.
Science was trying to take a shortcut trying not to deal with moral issues. There’s no elevator to success, you have to take the stairs! Induced pluripotent cells are cool but why spend all this time checking them out when the real need could be solved by using cells from the source. We need brave scientists who believe and are willing to take a chance. We can hope that in the future ways to obtain compatible cells become easier but in the meantime use what you have and make it happen.
