What we really need to work out is how we can incubate humans outside of the womb so we can create brain-dead humans for organ harvesting. Would be both more reliable and more humane than this. Plus you could harvest the heart, liver, etc at the same time. While this is great news, my understanding is that kidneys donors are in larger supply because often family members can give one of theres. This obviously isn't the case for organs like hearts and livers.
