"Bloody rotten
timing," as the Brits might say. On July 24, researchers in Rostock,
Germany, announced that two weeks before they had successfully transplanted stem
cells into the heart of a man whom, they report, is now doing well.
The problem? The cells
came from the man's own marrow. No embryos were harmed in the making of this
miracle.
What bloody awful news. It
does nothing to help the full-court press to force the Bush administration to
lift the funding ban on embryonic stem cell experimentation.
Which is why you've
probably heard about the German experiment for the first and last time.
You see, over the last few
months there has been a desperate effort to convince us that either (A), the ban
covers all stem cell research, (B) the only type of stem cell is from embryos,
or (C) if you have heard about non-embryonic cells, trust us, they're not worth
spit.
What the Ban-Lift Bunch
has on its side is celebrities like Christopher Reeve and Nancy Reagan, nice
people who either have or live with persons with severe physical problems. But
they don't exactly have medical backgrounds.
The Ban-Lift Bunch also
has full media support.
Consider a recent issue of
Newsweek, putting what it wants you to think is the entire argument right on the
cover.
"The Stem Cell
Wars," declare the boldest words. "Embryo Research vs. Pro-Life
Politics: There's Hope for Alzheimer's, Heart Disease, Parkinson's and Diabetes.
But Will Bush Cut Off the Money?"
Get it? It's pro-life
fanatics vs. science, pro-life fanatics versus the sick.
But actually it's science,
not abortion opponents, making the case for non-embryonic cells. Overwhelmingly,
the incredible breakthroughs in stem cell research have involved NON-embryonic
stem cells.
* A recent report in New
Scientist described the successful use of stem cells from adult human hair
follicles to create skin grafts.
* Two studies in Nature
Medicine reported that nonembryonic stem cells injected into rodents can
transform themselves naturally into neurons and insert themselves into the
brain, giving hope to persons with Parkinson's and other disorders. A third
study found that injecting a chemical into damaged areas of rats' brains
stimulated stem cells to grow and differentiate into a massive number of normal,
fully developed nerves. The cells were able to repair damage and restore
mobility to the rodents.
* At least four rodent
studies and one pig study have shown that nonembryonic stem cells can be
injected into animals with damaged hearts and repair heart tissue.
* As reported in Molecular
and Cellular Neuroscience, rats with degraded retinas were injected with
nonembryonic stem cells that traveled to the site of damage, which then showed
signs of making connections with the optic nerve and hence improve or even
restore vision.
* Johns Hopkins School of
Medicine researchers injected nonembryonic stem cells into the spinal fluid of
paralyzed mice and rats, half of which partially or fully recovered.
* Cells from liposuctioned
fat (North America's most plentiful resource) have been transformed into bone,
muscle, cartilage and mature fat cells, according to the journal Tissue
Engineering.
Time and again, scientists
involved in non-embryonic stem cell work, including even some who say they
support lifting the funding ban, have commented that one of the important
results of their and others' findings is that they would bypass the
emotion-charged embryonic tissue debate. Among them:
* Dr. Donald Orlic of the
National Genome Research Institute told NBC News in late March that, "We
are currently finding that these adult stem cells can function as well, perhaps
even better than, embryonic stem cells."
* Eric Olson, chair of the
Department of Molecular Biology at the University of Texas Southwestern Medical
Center say that almost "every other week there's another interesting
finding of adult cells turning into neurons or blood cells or heart muscle
cells. Apparently our traditional views need to be re-evaluated."
* Markus C. Grompe, a
professor of molecular medical genetics at Oregon Health Sciences University
said of one study: "This would suggest that maybe you don't need any type
of fetal stem cell at all . . . that our adult bodies continue to have stem
cells that can do this stuff."
One of the richest sources
of cells that are not adult, but more importantly are nonembyronic, are
umbilical cords and placentas from live births. Each year, more than 4 million
umbilical cords are simply discarded. Connected end-to-end, they would stretch
further than from New York to Houston.
Stem cells from newborns
are not only available in unlimited amounts, there's also reason to think they
may be far more versatile than the other nonembryonic cells used in the
aforementioned studies.
But it's not just that
embryonic cells are unneeded; pragmatism counsels that they should be shunned.
Much of the current fear
over therapeutic human biotechnology comes from angst over embryonic stem cell
research, expressed across the spectrum of the abortion debate. Rightly or
wrongly, use of embryonic cells invokes visions of Dr. Josef Mengele and a
spooky slippery slope toward playing around with human life.
Maintaining the ban on
embryonic stem cell research while we continue to watch the fantastic results
pour in from nonembryonic stem cell work will leap right over this moral chasm.
This action will not just promote stem cell research, but prove invaluable to
all future therapeutic genetic research and the vast promise it holds.
