Stem Cell cures (Health)
Extracting stem cells from adults (adult stem cell research) = Okay
Extracting stem cells from embryos (embryonic stem cell research) = morally repugnant
Stem cell research is fine as long as the stem cells that are harvested are not retrieved in a manner that destroys human life at any stage of its development.
"I tell you the truth, whatever you did for one of the least of these brothers of mine, you did for me." - Matthew 25: 40
