The Catholic Church has bio-ethics experts discussing this
constantly. The Catholic church is very careful
in considering all cases involving the use of human cells
to make some sort of decisions that make sense. From
reproductive technology, to using body cells/ stem cells
for research. This is horribly difficult.

So forgive me if you come waltzing in making such definitive
statements in an area where Science has got way ahead
of ethics. And not on purpose, not for some evil deed.
This is an area where many very religious people go through
a great deal of debate and agony because some
aspects are so complex.
