Stem Cell Research: What It All Means
Over the course of the past months and years, especially in
political, scientific, and religious circles, talk has begun of a
process which is called stem cell research. It is this process which
scientists feel has great potential in providing a future cure for
代写美国论文ailments such as Multiple Sclerosis and Parkinson ’s Disease to name a
few. Anyone who has seen actor Michael J. Fox testify in front of a
congressional hearing on the issue can start to begin to understand the
effects of Parkinson ’s disease in the form of bodily shaking and
tremors. It is the hope with the funding of stem cell research, people
like Mr. Fox and the hundreds of thousands of others who fight such
ailments will not have to do so. Unfortunately, as is the case with
everything else in life, this situation too proves to show a lack of
100% certainty. We as human beings just tend to find ourselves without
the luxury of having that. In return, it is left up to instinct and
brainpower to guide us towards answers to problems. The purpose of this
essay is to give a brief summation of what stem cell research is as
well as what it means for the scientific community and what they hope
to accomplish. Also the verbal battle it has caused to ensue between
entities ranging from a scientific lab to the White House, and going
all the way to Rome and the Vatican. It is with this kind of heated
verbal exchange that real reform can result. According to the official
resource for the National Institute of Health, stem cells and their
importance are described as: “Stem cells have two important
characteristics that distinguish them from other types of cells. First,
they are unspecialized cells that renew themselves for long periods
through cell division. The second is that under certain physiologic or
experimental conditions, they can be induced to become cells with
special functions such as the beating cells of the heart muscle or the
insulin-producing cells of the pancreas, ” It goes on to say, “Scientists
primarily work with two kinds of stem cells from animals and humans:

functions and characteristics that will be explained in this document.
Scientists discovered ways to obtain or derive stem cells from early
mouse embryos more than 20 years ago. Many years of detailed study of
the biology of mouse stem cells led to the discovery, in 1998, of how
to isolate stem cells from human embryos and grow the cells in the
laboratory. These are called human embryonic stem cells.
