I have made the observation that the line between any human stem cell and a human embryo is so thin that Pro Lifers will be faced with the possibility that ALL stem cell research of any kind is murder. The deduction is easy when you start with right assumptions.

It turns out that this issue is not to be left for future generations. Labs in California and Great Britain, at least, are creating human embryos in various ways. The upshot being that an embryo is an embryo. I believe the Catholic Church is way ahead on this - Every Sperm is Sacred, after all:

The process “involves creating human lives in the laboratory solely to destroy them for alleged benefit to others,” said Richard Doerflinger, spokesman for the U.S. Conference of Catholic Bishops.
