Because babies are not the only source of stem cells, they are now able to be produced through synthesis and can be extracted from a donor. The type of cell is important the article is not a scientific paper, so it does not mention if the cell is multipotent, pluripotent or totopotent (in the latter case this would mean non-ethical sources but be advised there ARE synthesis techniques pioneered that do not rely on harvesting embryonic stem cells). Just because stem cells are mentioned in this article it is not a given that these are embryonic or non-ethical methodologies.
Would it be possible for doctors at a parents request to extract foetal stem cells from a developing foetus in utero and then preserve and store them for the unborn childs own use later in life if necessary...a 'bank your own stem cells' approach?
While this wouldnt be of help to older generations could it not be helpful to the newborn through their lifetimes to have their own foetal stem cells being available to them WITHOUT any recourse to ethically problematic sources like abortion?
