Given the political problems that have come from using embryo stem cells, I was
wondering if anyone has suggested the following idea:
Whereas, there is no objection as to what you can do to either an egg or sperm
cell, it seems that it would be a good idea to alter one or the other (most easily
the egg) or both, before combination so that development past the point needed for
research cannot happen. Then, the combination should be called some new name that
is not "embryo" and the stem cells from it should continue to carry the new name.
It should also be designed such that whatever change was made before the
combination carries over to prevent the full term development of clone cells. A
good choice might be in the mechanism that gives rise to the placenta.
