One world Essay
Stem cell
Bong hee Han
In the human body 99.9% of DNA is exactly the same, only 0.01% of DNA
is different and it is the cause of all diseases and injury. In 1980 Ernest A
Maculloch and James E Till discovered last stem cell. Stem cells were announced
as the greatest cells in the human body, because they can propagate themselves
without any help except some. It can cure the patients’ diseases and injury. Stem
cell is the best cell in our body to cure any diseases and injury even there are
many difficulties. Benefits and difficulties of stem cell are depending on how the
human use stem cell in good way or bad way. It will help humans to develop a lot
and the development could be evolving human being. This essay is about how
stem cell works, 3 benefits, 3 limitations and 2 one‐world issues, which are
ethics and social.
Stem cell is a cell that can renew any cell and cure a person. It is the cell
that uniquely grows specially; because stem can copy themselves. In order to use
stem cells to cure humans, we need to put in the signal to the cell and the cell
begin the change the cell because signal order stem cell to change type of cell.
The cell will continue make the clone of the type of cell to make new protein.
Basically, there are two types of stem cell has two parts, which is the embryonic
stem cell and adult stem cell. Embryonic stem cell is a fetus and adult stem cell is
from people who have already grown fully. This is the reason of why people get
hurt; they need to cure themselves for adult stem cell exists. Embryonic stem cell
is for development of the baby. From one cell it makes the copy of cell and make
the all body part from one cell. Both have almost the same function in our bodies.

Totally, there are three benefits to stem cells. First of all, both stem cells
can provide new treatments of disease and injury, also it provide new scope of
science. This stem cell uses are not complete to use so scientist can discover the
new treatment. Secondly, stem cells can cure most of diseases and injuries.
Curing the most diseases and injury is how great it is. When we discover the
treatment fully it could be the best cell. Lastly, there is one benefit for each type
of stem cell. Embryonic stem cells can develop into any type of cell and make
copy of the cell. When we inject embryonic cells to any part of cell, it can make
the copy of that part. The benefit of adult stem cells is that the risk of stem cells is
reduced because adult stem cells come from the patient. When we put patient’s
own cell it has same disease cause it has same DNA with the patient. These
reasons are why accept group is allowed to use stem cell.
There are also some difficulties of using stem cells. First of all, the
technology and medicine of stem cells is completely unknown to use to patient. It
means for now we cannot use stem cell treatment because it is too danger to use.
And it can be helpful to human beings but it also can be harmful treatment to
human beings. Secondly, stem cells can make coronary arteries become

narrower. It is one of the bad effects when we use other’s stem cell. One patient
who injects stem cells and had heart problem get this problem. Lastly, the
difficulty of adult stem cells is that they only can make same types of cells. For
instance, blood stem cells can only copy blood cell and skin stem cell only can
make skin cell. Difficulty of embryo is that embryonic stem cell is not patient’s
own cell so it could not be matched. Embryonic stem cell have it’s own DNA so it
could not be matched to patient’s body. These reasons are why people do not
allow using stem cells.
Stem cells raise an ethical issue. Ethical is the main one world issue of
stem cell treatment. Using embryonic cells is killing baby by the human. Such as
the animal do not kill each other if that is same kind of animal, only human can
kill each other. Even though an embryo is not yet structured to baby but after
nine months baby will be born. It means people are killing embryo that would
have life. Death is not an embryo’s decision it is only decision of people, and they
will not enjoy any human rights. This ethical problem is why people mainly want
to prohibit researching the embryonic stem cell.
Stem cells also raise a issue. Socially stem cell is big shock to somebody
such as scientist, government and patient. All diseases and all injuries could be
cured by stem cell except 10 diseases and injuries. Today we have too much
diseases and injuries that we cannot cure. But stem cell help human being to
make the bright world, which is only few diseases and injuries over the future.
Also using embryo could be dangerous to the population of world. As I said
technology is completely unknown for research more about stem cell it need
embryonic cell to supply to scientist. According to social issue stem cell is
essential to human’s medical subject.

5. BongHee Han
In conclusion, stem cell has more benefit than difficulties. Stem cell should
improve over the future to cure all diseases and injuries until no patients. There
are some harmful reasons not to use it, but it would be solve the problem after
research is finished. Topic of one world essay that is stem cell was good because
student should know this. Because stem cell will change our future. Scientist
need to continue to investigate stem cell, government need to aid in financial
way cause it is too expensive to do it alone. In my opinion stem cell should
continue until investigation is 99.9% complete, so finally human being’ can be
helped by stem cell.
