What You Should Know about Stem Cells Essay -- Stem Cells Science Ethi

What You Should Know ab disclose Stem booths A topic of all-encompassing scientific and ethical debate in our society as of later(a) has been the question of Stem Cell investigate. Going down this path could give back unprecedented medical leaps in treatment and prevention that medicine pass on be able to offer. Before I address the debate of whether or not Stem Cell research should be done, I sine qua non to first rationalise to my readers what stem cells are, how they come to be and what we can expend them for. We must first start with the different types of cells, I will explain them as I take you through part of the fetal training process. The first type of cell is the totipotent cell. This cell is created when a sperm fertilizes an egg. This kind of cell can force some(prenominal)thing within the homo body. after(prenominal) four days the totipotent cell begins to specialize by meet a blastocyst. The blastocyst contains an outside layer of cells and an inside cell mass. The outer layer of cells will become the placenta and other support tissues for the foetus as it develops. The inner cell mass will go on to become virtually every type of tissue within the human body. The inner cell mass cannot create a placenta. Since it cannot form a placenta, it is no longer totipotent. It now becomes pluripotent, a cell with the ability to become any number of tissues within the human body. This is the cell that scientists are interested in. unitary part of Stem Cell debate is the question of when is a fetus a fetus? At what maculation is the potential for human sprightliness extinguished? At this stage the pluripotent cells while able to form virtually every human tissue, cannot for a placenta. Therefore if you were to place the cells into another cleaning lady?s uterus a fetus would not develop. From this point the pluripotent cells foster specialize and become the cells that create heat tissue or heading tissue etc. We ne ed to understand the complex events that occur at this stage of development. There are genes referred to as ? termination making? genes. These genes show how and what the pluripotent cells become. Now I will get into the possible benefits of Stem Cell research. Once we learn how the decision making genes work we can thus begin to use the pluripotent cells to create the typed of tissues needed to treat patients with various types of unsoundness and disease. There is a bonus here as well. Birth defects an... ...t point come we may have already come to an ethical decision on what to do and with the knowledge already gained in research of grown stems cells we should be able to proceed quickly. Stem cell research is unbelievably important. We as a civilization are standing on the edge of a major leap for our society and we must take that leap. Who knows that kinds of doors this research could open, who knows that other leads it could unveil for us? This research has the a bility to change out culture, like the discovery of fire and the harnessing of electricity. We can?t let it work shift away.Works ConsultedAdult Stem Cells May be Redefinable. 24. Oct. 2001. British aesculapian Journal. 24.
