Ethical dilemmas (Stem Cells)

Have we found the ultimate stem cell? One that can deliver all the benefits of embryonic stem cells without having to destroy a potential human life to save an existing one? It's too early to tell, say stem cell researchers. While they are excited about the potential of an adult stem cell like Verfaillie's, most insist that research with embryonic stem cells must continue, because nobody can possibly know right now which option is better.

And it might be worth it for more than one reason, says Arthur Caplan, director of the Center for Bioethics at the University of Pennsylvania. Many scientists - Verfaillie included - are patenting their discoveries, which could hinder their widespread use. We need to keep all options open, he says. But in the US, federally funded researchers have only just been allowed to work with a limited number of ESC lines. Opponents of such research, who have long touted adult stem cells as an alternative, are likely to seize upon Verfaille's results.

Moral line

As Richard Doerflinger of the US Conference of Catholic Bishops puts it, the only reason many lawmakers have felt compelled to "cross the moral line" in backing ESC research is because they believe it's the only way to get the full benefits. Indeed, Erik Parens of bioethics think tank The Hastings Center believes the discovery could have a negative impact, letting the US dodge the kind of debate over embryonic research that countries like Britain have had.

The discovery could also affect the cloning laws being drawn up around the world. While banning reproductive cloning, countries such as Britain have permitted therapeutic cloning because doctors could use it to obtain ESCs.

I have listened to the embryonic stem cell supporters at work. The make some very odd statements. Many totally disregard any adult stem cell research and an alternative. They seem to act like embryonic stem cell cures are vindication that abortion is good. They might have a minority view but they are unwaivering.
