BongHee Han 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.
BongHee Han Figure 1‐Embryonic cell (Unknown, Getstuff, Oct 2008) 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
BongHee Han 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.
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.
