After I posted that I googled transplant organs from infant to adult and I found an article on the NIH website on kidney transplant. From infant to adult results are only fair, good results from 2 year old to adult. So if someone goes a kidney from a 2 year old donor, is that a 2 year old who as died or a kidney that has been grown in a lab for 2 years. People who need organs to live are desperate and grateful when they get their transplant. How many question how the organ is obtained.
I’m sure there are plenty who would never question it at all. But I’m not at all sure you could keep a fetal liver, etc. “alive” for any length of time and I also do not see how it would “grow”.
