It seems to me that this question, whether there should be a "market" in
body parts, is not quite the same as the broader issue, which is whether
people support medical technology that can create replacement body parts.
I don't know how the actual survey question was worded, but this talk
about a "market" conjures up images of people selling their body parts,
which is something that has long been opposed. I question whether we
can take this 48-48 split to apply to medical biotech in general, and
artificial organs in particular.
One thing I'm not clear about is whether the technology for artificially
growing human organs would be based on the user's own tissues, or whether
it would be based on someone else's tissue. The former would be superior
in terms of rejection, but it would presumably take longer. If you need a
new liver you may not be able to wait months for one to be grown. Also,
doing it from your own cells would require regressing them to the stem
cells stage, which is new technology, whereas getting them from someone
else could start with fetal tissue, making the task simpler.
These two approaches would likely have very different levels of ethical
acceptance from the general public.

I'm surprised they didn't ask how many people support cures for AIDS and
cancer. It's going against God's will, after all...
BTW the online prediction game Foresight Exchange http://www.ideosphere.com/
is much more pessimistic about a cure for cancer by 2010, giving it 38%
odds, which is more in line with what seems reasonable to me.
