2. O ne World Essay
Seung Hee Shin, Grade 9
Today, many researchers are focusing on the stem cells. Stem cells are amazing, we can use them
in lots of ways. One of the amazing work that stem cell can do is cloning. Much of the stem cell
research is directed towards human cloning because of the stem cell's ability about transform into
any other types of cells. There are two types of human cloning. They are reproductive and
therapeutic. Reproductive cloning is an essential cloning way to produce children. However
therapeutic cloning is used only for scientific research. While cloning to produce children is
impossible yet, stem cell researchers hope that one day it will become a feasible option. (Interesting
Facts About Stem Cell Research .2009) As you read, the ability of the stem cell is nice. Now, I will
introduce about the stem cell, I am going to tell you 3 advantages of stem cell and 3 disadvantages
or limitations of stem cell. Also, I am going to discuss ethical and economic issues of the stem cells.
[Figure 1, Stem Cell Therapy Effective in Treatment of 12-Year-Old with Diabetes.2010]
Stem cells are not differentiated cells. They can differentiate into specialized cell types, and they
are used to birth of the tissues. For example, it can be skin cell, heart cell etc(Figure 1). Also they
are using in medicine, so the person who has disease can be treated by stem cells. We use them in
regenerative machine, because stem cells can be various of organs. For example, Parkinson's
diseases, Neuron is dead and the person get hands and feet paralysis. We can put stem cells in his
dead to treat Parkinson's diseases.
There are 3 benefits of using stem cells. First, National income would be increased. All the people
can sell their stem cells, also the beggars can sell their stem cells, when they need money. However,
it can be illegal to sell the stem cells. Today, there are lots of people doing trafficking of human
organs. So that selling of stem cells can be illegal. I will talk about this problem in detail later.
Second, stem cells are very useful. Stem cell can differentiate into lots of cells in our body. So we
use them in the medicine that can treat diseases. Stem cell is pluripotent cell. Third, the lifespan will
be increased when researcher invents the methods how to use stem cells in the medicine, and when
the stem cell therapy becomes legal.
There are 3 difficulties or limitations to using stem cells. First, we need lots of ovum to make
embryo, but there are limited. However at 18th of december in 2008, a korean scientist said that they
have successfully used nano and bio technologies. So that they can grow nerves, muscles and liver
tissues from stem cells. The discovery made by a team led by Park Se-pill, a life engineering
professor at Cheju National University, used magnetized nano particles to insert genes into the stem
cells of laboratory animals that differentiated into specific tissues. The research published in the
latest issue of the international Stem Cells and Development journal is noteworthy because it did
not use the dangerous retrovirus or inefficient chemical-electrical techniques that are currently
employed in these experiments. Retroviruses are used in so-called gene delivery systems, but they

3. are believed to cause serious side effects since the tainted stem cells could trigger cancer and
immune disorders. In the chemical-electrical technique, a high percentage of genes are lost in the
delivery process. (Koreans succeed in stem cell work .2008)
[Figure2, made by Seung Hee Shin]
In result, the problem of the limitation of the ovum is resolved. As you read before, while a stem
cell researcher Hwang Woo-Suk used ovum to make stem cell, Park Se-Pil didn't use ovum.(Figure
2)
Second, when uses the medicine which contains the stem cells, the failure rate is high. However, at
27th of June in 2008, a Pusan high school professor Kang Soo-Kyeong removed the weak point of
the stem cells made from somatic cell. About 3years ago, we used the stem cells which is made
from somatic cell with virus or gene. So the failure rate was really high, because the virus or gene in
the stem cells could be cause of malformed child, cancer etc. A team led by Kang Soo-Kyeong
changed the method of making stem cells to use somatic cell. They used low molecular compound
from the plant instead of virus or gene. So that this new cell differentiation became safer. In result,
the problem of the failure rate of the stem cells is resolved. As you read before, Kang Soo-Kyeong
changed the method of making stem cells, so that the failure rate of the stem cell treatment is
getting lower. However there is really serious problem after making stem cell. I will talk about it in
detail later.
Third, if we want embryonic stem cells, we must break the embryo. The embryo can be a
life(living thing). Also the embryo is limited. Breaking the fertilized is murder if it is life. I think it
is a life, because it becomes human. The first figures of all of us are the embryos. Some people say
that it is not a life, so some ethical problems are occurring even now.
I state 3 disadvantages; failure rate of the stem cells, whether embryo is the life or not and the
limitation of ovum. However one of them are already resolved. I hope to resolve other 2 problems
of stem cell.

4. <Ethical Issue>
I chose ethical Issue of the stem cell. Today, some ethical problems are occurring. For example,
whether embryo is life or not. I already talked about this problem. What I am going to talk about
for my one world essay is that the illegal therapy of the stem cells.
Today, there isn't any skill for control the stem cells, it means that even scientist can't be sure that
what stem cells differentiate into. For example, a doctor put the stem cells in a patient's brain to
make the stem cells differentiate into the brain cells, but the stem cells differentiated into skin cells.
This situation can be occurred, because we don't have a skill to control them. So the stem cells
therapy is illegal yet.
There are 2 different kinds of experiment to the living thing. They are animal experimentation and
a medical experiment on a living body. Many researchers are doing animal experimentation of stem
cells therapy. However it is essential to a medical experiment on a living body to make sure. Then
now, the doctors have to say that “The failure rate is high, it is dangerous.” to the patients. Then let
them choose whether do it or not. Actually, the doctors exaggerate the facts, it means that they say
that “This stem cell therapy is really nice, I can guarantee the therapy is safe.” to the patients. Then
of course the patient say “yes”. It is very unethical situation. But in many hospitals, that situations
are still occurring.
There are 2 evidences why stem cell therapy is an ethical issue. First, I found an article in BBC
news site that is about the exaggerated claims.
-> 'The GMC will consider allegations that Dr Trossel acted dishonestly, abused his position as a
doctor and exploited vulnerable patients with multiple sclerosis and Hodgkins' disease by offering
treatments which were not in patients' interests and not justifiable on the basis of scientific
evidence.
He is accused of failing to warn patients of the potential risks of stem cell therapy and
exaggerating the benefits.
He is said to have sent literature to one patient in 2006 which claimed that he personally had
treated "approximately 120 patients over the last year and a half of which half had MS and 10%
were now walking out of a wheelchair. Another 80% have had a proven significant clinical
benefit.....". '(Stem cell doctor GMC hearing begins .2010)
As you read, Dr Trossel exaggerated the facts. It is unethical. I found an article in Health Korea
News that the first person who got side effect of stem cell therapy.
->'Using stem cells to treat adverse events occurred in the world are keen to have the medical
community.
Bangkok, Thailand, led by Dr. Duyangpen in Chulalongkorn University- Canadian co-researchers
reported in the Journal of the 17th American Society of Nephrology materials treated with stem
cells from the damaged kidney tissue of patients detected cases, he said....'(Joo Min-Woo ,2010)
A control skill has to be discovered quickly before many people would be sacrificed.

5. <Economic Issue>
I chose economic issue for this one world essay. An issue is that the range of the stem cell market
will be getting increase, and bigger. So that the country income will be increased. The stem cell
markets have grown from zero to $87 million in less than three years, and analysts at the year's stem
cell summit were bullishly forecasting its growth to $8.5 billion over the next decade. Most of the
initial growth is likely to come from the adult stem cell side, where developers have focused on new
therapies. In result, the stem cell markets will be the best market in every countries.
There are 2 evidences to support my issue. First, I found an article in the news site which is about
the stem cell market.
'Stem cell research companies in the stem cell therapy as early as within 5 years would go on sale in
the country are expected. The minimum size of the industry in 2011-2015 was expected to be about
1 trillion won. Because of this, the economic expectations of investors, as well as the treatment of
incurable diseases is growing hope.
People with incurable diseases permitting stem cell therapy, Russia, India, Thailand, Mexico and so
stem cells is also possible to undertake medical tourism. Although accurate statistics are yet in
Korea, these patients are increasingly it is an analysis of the industry. (Stem cell therapy comes to
age.2010)'
The second evidence is about the stem cell market and therapeutics. Stem cell therapeutic is very
important, because the stem sell market can be formed of stem cell therapeutic.
'Political and business events presage change for stem cell therapeutics, most notably the expected
move by President Barack Obama to lift federal funding restrictions on stem-cell research. The U.S.
Congress has also indicated a desire to move forward with stem cell research. The momentum in
two branches of American government, along with scientific developments and the competition of
world markets presages good market conditions for stem cell research.
With their ability to differentiate and become an ongoing source of cells that make up critical tissues
and organs, stem cells have potential for new regenerative therapies and as new research tools for
drug developers to test emerging therapies on diseased cells.(New Report On Stem Cell
Therapeutics Markets Added In Visionshopsters.2010)'
