I now Mike is really annoyed by Bush's order, and I am, too. But what
annoys me most was the fact that Bush was told that we did not, in
fact, have really enough existing stem cell lines to support near- to
mid-term research as a matter of fact, but Bush claimed that we did.
In retrospect, it was one of the first well-known cases where the
administration twisted or invented facts so that they appeared to
support a policy position that was developed independently of the
facts.
I've never understood this argument at all, and I've suspected duplicity
on the part of those who make it. Probably just my ignorance... Feel
free to educate me.
Why is more than one stem cell 'line' even necessary except perhaps as a
way to increase the speed of production of stem cells for research.
Is a stem cell differentiated from the stem cell of another embryo in
such a way that different 'varieties' must be available for different
research. I had thought the very definition of stem cell was that there
was no differentiation.... that it was a blank slate.
I've really been under the impression that if you started out with one
stem cell and managed to duplicate it and then duplicate those and so on
and so forth that you would have all the stem cells you need, but that
mortality and time were reasons people wanted to do 'multiple lines'
simultaneously to produce more cells for research exponentially more
quickly.
Please explain to me the concept of a 'line' and why X number of 'lines'
is not sufficient, but Y number of 'lines' would be.
Also, please reacquaint me with the numbers. I seem to recall there
being 32 available and that it was something like 50 that were wanted
when Bush said, "Read my lips, no more 'lines', go with whatcha got."...
I'm probably nowhere in the ballpark here. It's been quite a while.
