I think a lot of it is lost in legalities because it involves stem cells. I'm unsure. When my son was born some new labs reached out wanting to charge a ton to perserve the placenta because there are stem cells in it and can be used in a bunch of ways. It opened a bit of a rabbit hole I went through for a couple days.. It seems many scientists link stem cells to it but depending on the country a varying amount of research into it is illegal to do.
