I think we should use it because it could help save countless lives. I think they aen't useing it because its not 100% tested and incredibly religous people saying its going against god.
see I've never understood that, because 1. you need to test with the embryos to make it 100% tested and 2. anyone found a quote saying god is anti-stem cell research?
I think it would be selfish for religions to stop it as religions are surposed to be about helping people and its not really harming anything.
