Embryonic
stem cell research has received major press coverage since
Ron Reagan’s speech at the Democratic National Convention.
Judging by convention speeches, and the media reports that
followed, one might think that President Bush is limiting
all stem cell research, and holding back future cures for
many of the diseases that have plagued our loved ones. Nothing
could be further from the truth.
What
has not been made clear by the media, and is critical to
understanding this debate, is that there are actually two
different types of stem cells that can be used to cure diseases:
adult stem cells and embryonic stem cells. Adult stem cell
research has been on-going for 20-30 years, is not under
any government restriction, and does not require the destruction
of human life. These stem cells have already been used to
treat spinal cord injuries, Leukemia, and even Parkinson’s
disease . Adult stem cells are derived from umbilical cords,
placentas, amniotic fluid, various tissues and organ systems
like skin and the liver, and even fat obtained from liposuction.
In
contrast, embryonic stem cells are obtained by harvesting
living embryos generally 5 to 7 days old, which are destroyed
in the process. Most importantly, embryonic stem cells have
never yet been successfully used to help cure disease. In
fact, in animals they have caused tumors and other complications.
Embryonic stem cells are also being touted by some as a
possible treatment for repairing the brains of Alzheimer’s
patients, but stem cell researchers confess that this is
a distortion that is not being aggressively corrected by
scientists. Michael Shelanski, co-director of the Taub Institute
for Research of Alzheimer’s Disease and Aging of the
Brain at the Columbia University Medical Center in NY, says
“embryo studies may lead to insights into Alzheimer’s”
but “the chance of doing repairs to brains by putting
in stem cells is small” . In addition, the type of
research most frequently cited, requires the creation of
cloned human embryos – which neither the public, nor
Congress is willing to support .
A
new poll, conducted by International Communications Research,
reveals that once Americans understand the difference between
adult and embryonic stem cells, Americans strongly prefer
funding adult stem cell research that does not destroy human
life, by a margin of 61% to 23%. So, what is driving the
biotech industry and many government officials to press
for government money to subsidize embryonic stem cell research?
Free money, and research without ethical limitations. Private
industry has not been willing to put up any large sums of
money on their own for embryonic stem cell research, because
they are not sure it will yield the results they hope for.
However, some drugmakers are getting into the field of research
utilizing adult stem cells from umbilical cord blood and
bone marrow . Investors are now taking notice that adult
cells are actually working with human patients , and researchers
are finding that these cells appear to be as flexible as
the embryonic type . Politicians, like those in NJ, who
are being told that they need embryonic stem cells to boost
biotech development, should take note, especially since
the state budget cannot afford any uncertain investments.
Despite
the exaggerated promises made for embryonic stem cells,
such research requires the destruction of human life. Adult
stem cell research does not, and has already been used to
successfully treat thousands of patients. Let’s put
politics aside and put our efforts behind the research that
is both ethical and effective.
