Not necessary. A cell (with a nucleus) has all the DNA required. You just need to have a viable system to build up a human from it. I think right now this is not possible, but this will be solved eventually. The question is, though: do future humans really want to do that?
replyDon’t be so sure. I hate to draw the comparison but raising a child in an artificial womb is probably at least as difficult as growing chicken wings in a sterile environment. A startup founder that wanted to grow meat pivoted to lab grown egg whites, in his words in order to grow a cube of solid meat any bigger than a centimeter cubed, you could not keep it sterile, it is too attractive of a growth medium. In the case of a chicken, it’s like the rest of the bird is needed to provide an immune system so the meat doesn’t spoil.
replyMothers provide more than a growth vat to their children, not to mention the immunities passed on in breast milk.
To birth a child in a sterile vat, they would likely need to be kept in a bubble the rest of their lives too.
