One world essay “Stem Cells”<br />Jung Min Kim, G9L<br />These days, the average life span of the people is rising. Above all, the stem cell's treatment is the most interested heal to the whole world because it has inexhaustible possibility of treating the disease perfectly without the side effect. Stem cells are very useful us to live. What are stem cells? (See Figure 1) Put simply, stem cells are all cells found in multi cellular organisms. They have the ability to develop and grow to any kind of cells through mitotic cell division. In this essay, I am going to explain about what is stem cell, advantages and disadvantages of stem cell, what they can do and two types of the one-world issues which are ethical issue and social issue.<br />What are stem cells? Stem cells are cells which are found in all multi cellular organisms. Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. (Stem cells basic, 2009). Stem cells have the differentiation ability. But it can't do differentiation. They have only ability. And there are two types of stem cells. They are embryonic stem cells and adult stem cells. The embryonic stem cells (See Figure 2) are derived from embryos that develop from eggs. Embryonic stem cells are called “Master Cells”. And adult stem cells are thought to be an undifferentiated cell. The stem cells are used to treat incurable diseases like fertility, Parkinson's Disease, Pneumoconiosis, atopic dermatitis and Hemophilia. These are some features of stem cells.<br />Figure 2: Embryonic stem cell (Genes That Are Associated To Aging Has A Role In Stem Cell Differentiation, 2010)<br />There are many benefits and reasons of using stem cells in medicine. First of all, they can treat incurable diseases like atopic dermatitis, cancer and so on which are impossible to treat. If you lost an important organ in your body, you can use stem cells to repair it quickly, and it will grow back to its original shape. RNL Bio which is professional Bio company of adult stem cell therapy products was saying that the man who had psoriasis disease (It is one of the skin diseases. It is assumed that psoriasis patients are 2-3 percentages of nation's population.) was relieved symptoms because he got treatment which is using stem cells of RNL Bio. Stem cell therapy is sometimes called regenerative medicine. Also, we can make any cells using embryonic stem cells. So we can even make many clones such as Dooly (See figure 3) which is the cloned sheep. Dooly was the first mammal's cloned, it was born by using full-grown sheep's stem cells in 1996. Also in 1997, Polly and Molly which have human gene were born using to apply the same type of producing technique of Dolly. These are something which are good things of using stem cells.<br />Figure 3: Dooly (Jin Kyung, 2006)<br />If there are many benefits of using stem cells, there are also many limitations of using stem cells. Firstly, It can be dangerous by using stem cells. The side effect is the most typical example. As mentioned earlier, Dooly is the cloned sheep. It was passed away by euthanizing (that time was that Dooly was born in six years), because the symptom which is a progressive lung disease was appeared to Dooly (that time was that Dooly was born in three years). So naturally, the story was concerned the emergence of human clones among the people. The film 'Island (2005)' arouses a person's wariness about the side effect of cloned life by showing the future which is predictable. Also there is a risk of immunogenic reaction as stem cells from a random embryo donor are more likely to face rejection after transplantation. Since the stem cells research is new, it is completely unknown what the side effects and harm it could have to humans. For it to be useful for transplant purposes, stem cells must be reproducibly made to generate sufficient quantities of tissue, differentiate into the desired cell and the person receiving the transplantation must be able to survive it, the body might reject the tissues being transplanted, if the cell divisions gets uncontrollable, it might form cancer. (How stem cells..., 2010) These are something which are bad things of using stem cells.<br />Also there are two types of one-world issues. The first of stem cell researches is the ethical problems about using embryonic stem cells. Some scientists who have studied about stem cells found that the embryo appears to have many same qualities of the organs which is in our body. The use of embryonic stem cells involves the destruction of 5 to 7-day-old embryos. So it has raised moral and ethical issues amongst the public. There are two opinions about using embryonic stem cells. It looks like a scale of both arms. The people who agree using embryonic stem cells assert that one life(an embryonic) can save many people. But the people who disagree using embryonic stem cells assert that an embryonic doesn't be born, but it is a breathing living thing as us. So the embryonic stem cell research makes that the destruction of embryonic stem cell is one of the murder. For this reason, some people believe it would help improve the quality of life for people who are illnesses, but some people desperately oppose the research of embryonic stem cells. These is the arguments which is about using stem cells.<br />The second of stem cell researches is the social problems about the illegality of ovum trading. Since the end of 20th century, the biotechnology has been rapidly progressed. Therefore, human ovum became the most important and fundamental material for the experiments and the treatments. So The people who found that the embryo has many same qualities of the organs which is in our body started to trade a lot of human ovums under the counter. In particular, gathering and trafficking in human ovum have raised the legal and the ethical discourses among legal scholars. In this context, the Korean parliament enacted “Bioethics and Safety Act” and this Act entered into force in 2005, which prohibits from trading human ovum. So the disclosure of an illegal ovum trade had made a big splash in Korea. It even made people look suspiciously at the stem cell research of Hwang Woo-suk(He is the most representative veterinary and biotechnology scholar of Korea.), the renowned Seoul National University professor and stem cell researcher. But our worst fears became a reality. In other country, Japan, they did to trade the human ovums under the couter through the internet in 2005. So they was punished by the government. These is the problem of illegal ovum trade which is related the social.<br />In this essay, I have explain about stem cells, their benefits and limitations and the two types of one-world issues (ethical problem and social problem). We can treat and save many people's lives who have incurable diseases by using stem cells. But it can have side effects. So some people completely disagree about using stem cells. People have to find out the way that all people enable to feel satisfaction about stem cell researches. I think stem cells are very helpful and useful to us by treating, so stem cells make people happy. On the one hand, I am so sad because for saving the people, we should to use stem cells but using embryonic stem cell is killing the one of life which is alive and breathing. <br />Works Cited<br />"
