For years I have said that embryonic stem cell research
is both deeply unethical and a scientific dead-end. But the prevailing winds of culture were
against me and I was dismissed or simply pooh-pooed. I didn't know what I was talking about,
apparently. People up on their
scientific conventional wisdom were of the mind that embryonic stem cell
research was a kind of obvious magical cure for all kinds of horrific diseases
(at the time, personified by Superman, Christopher Reeve, and Michael J. Fox). Embryonic stem cells are undifferentiated
human cells that could, theoretically, be coerced into any kind of adult cell
and be used to replaced damaged tissue as in the cases of severe spinal injury
and Parkinson's. The promises were
through the roof.
The catch, however, was twofold. First, all the significant trials with induced
embryonic stem cells created runaway tumors in their host, and in great
quantities were deadly. Secondly, the
only way to harvest embryonic stem cells was to kill (or make use of donated
dead) fetuses. A baby had to die or be
killed in order to pursue this highly suspect line of research. It was an obvious encouragement for the
abortion industry.
But the word on the street was that we had to do it, we
needed to pump hundreds of millions of dollars into it, and that anyone who
opposed it (usually those crazy Republicans and/or conservative Christians)
were backwards and anti-science. The
alternative being bandied about was the research behind adult stem cells. These are already differentiated cells (such
as stomach and skin cells) that could be harmlessly harvested and then
chemically induced "backwards" into the kind of pluripotency promised
by embryonic cells. But, no matter what
the research showed, the scientific community's and pop-culture's money was on
embryonic cells.
Some quotes from the article:
They have learned how to reprogram adult cells so that
they can do many things an embryonic cell can do. No human embryos are
destroyed in the process. Along the way, embryonic stem cells—just a decade ago
hailed as the future of medicine—have largely been bypassed. Some researchers
still use them, but for now, the future belongs to adult stem cells and iPS
cells, which are adult cells genetically reprogrammed to express specific
genes.
Every year for the past 10 years, the National Institutes
of Health (NIH) has funded more adult stem cell research compared with
embryonic research. For 2012, NIH grants totaled $146.5 million for embryonic
stem cell research, but $504 million for adult stem cell research—a difference
of $357.5 million. And the belief that adult stem cells are more promising than
embryonic stem cells for therapies is now largely mainstream.
And later, the researcher highlighted in the article
notes this about the debate in the past:
Hess said that the early 2000s brought fierce public
debate over the ethics of destroying human embryos to acquire stem cells.
Researchers and advocates for the use of embryonic cells promised that
scientists would discover a miracle cure for Alzheimer's or Parkinson's.
"There was a lot of magical thinking going on," Hess said.
This "magical thinking" was so bad that Charles
Krauthammer, himself confined to a wheelchair, called out both Reeve and Fox
for selling false hope to a lot of vulnerable people.
Part of what is so interesting about this to me is that
there was a time when people were being coerced into a point of view based on
conventional wisdom and emotion, and almost nothing else. Their voting habits were being scrutinized on
the basis of whether they were going to vote "pro-science" and for
embryonic stem cell research, or if they were going to side with the
troglodytes and be "anti-science."
It was a big, public deal. It embarrassed
a lot of people into a view they did not hold personally. And it was all false.
You used to hear a lot about embryonic stem cell
research. Will you hear anything about its
demise? No. Why? The research is a really big deal and really
does have all kinds of promise, so why? In more cases than not, it might be because to
report on the truth now will embarrass those who misrepresented it in the past.
Is it possible for the scientific conventional wisdom to
be dead wrong? Of course it is, and most
people who consider themselves "scientific" or scientists of one kind
or another would agree. But they agree
in principle. Disagree with one of their
currently held talismans, and you better have thick skin.
Does the work of science have built in fail-safes that
are supposed to correct for false views and present views as accurate or true
based on research and evidence? Again,
theoretically, yes. But it doesn't
always work that way, in fact, I might argue it almost never works that way on
the pop-culture level of science. Either
you believe what the force of conventional wisdom believes or you will become
the target of unrelenting personal smears.
And it should be noted that when a point of view begins defending itself
with the ad hominem argument, its defenders either have not thought through
their reasons for belief or there aren't any to be had.
And, finally, I find it provocative that a point of view on
this scientific issue 10 years ago which was informed by good Christian
theology alone has turned out to be supported by the research. Could it be that accurately comprehending and
articulating orthodox Christian theology is a clearer, long-term guide to truth
in life than scientific conventional wisdom?
Well, now it's time for the long knives to come out.
