Stem
Cell Research
Currently, there are two different types of stem cell research. The
first
B
and least controversial
B
is adult stem cell research. The second and much more controversial is
embryonic stem cell research.
Although most cells within an animal or human being are committed to
fulfilling a single function in an organ like the skin or heart, a
unique and important set of cells exists that is not so specialized.
These stem cells ‑ cells that retain the ability to become many or all
of the different cell types in the body ‑ play a critical role in
repairing organs and body tissues throughout life. Although the term
"stem cells" refers to these repair cells within an adult organism, a
more fundamental variety of stem cells is found in the early stage
embryo. These embryonic stem cells may have a greater ability to become
different types of body cells than adult stem cells.
Some
scientists point to the potential benefits of adult stem cells that are
obtained from organs or tissues such as bone marrow. They argue that
adult stem cells should be pursued instead of embryonic stem cells
because they believe the derivation of stem cells from either embryos or
aborted fetuses is ethically unacceptable. However, other scientists
believe adult stem cells should not be the sole target of research
because of important scientific and possible technical limitations.
President Bush has stated he will support embryonic stem cell research
on stem cells already obtained from embryos prior to August 9, 2001.
This means he will not allow federal funding for any further removal of
stem cells from embryos, and scientists must work with what has already
been extracted.
Some
feel the President did not go far enough on the side of research while
others feel this type of research violates the fundamental basics of
human life.
We are in the midst of a tremendous new debate; in
the midst of a tremendous new policy direction; in the midst of a
tremendous new revolution. We cannot afford to treat the issue of human
embryo experimentation lightly, nor can we treat it without serious
debate and deliberation.
We must ask ourselves, what makes up human beings?
What is the human spirit? What moves us? What separates us from
animals? How about the human soul? Scientists and medical researchers
