The problem with this
is that a person's own adult stem cells are multipotent
and not pluripotent
, meaning the latter can develop into any
kind of cell. In addition, the ability to "rebuild organs and spinal chords" is an example of the type of research that has essentially been obstructed to the point that lives that could be saved are not -what's needed are the more pluripotent embryonic stem cells over the multipotent adult stem cells.
Admittedly, stem cells harvested from the recipient have the distinct advantage of being less prone to rejection, however, they're also less likely to develop into the specific cells you need, making research more costly, difficult, and restricted.
Again, there are embryos that will be destroyed -dropped, literally, in the garbage, which can be used for good purposes. These are blastocysts of a few hundred cells at most with no brain
, no nervous system, and, thus, no brainwaves
. They're less intelligent than the bacteria growing in my intestine.
