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

What You Should Know about rootage Cells A topic of extended scientific and ethical debate in our society as of late has been the question of Stem Cell research. Going down this path could yield unprecedented medical leaps in treatment and prevention that medicine will be able to offer. Before I address the debate of whether or not Stem Cell research should be done, I want to first formulate to my readers what stem cells are, how they come to be and what we can use them for. We must first start with the different types of cells, I will explain them as I induce you through case of the fetal development 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 get under ones skin anything within the human body. After four days the totipotent cell begins to specialize by becoming a blastocyst. The blastocyst contains an outer layer of cells and an inside cell mass. The outer layer of cells will b ecome the placenta and other support tissues for the fetus 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. One part of Stem Cell debate is the question of when is a fetus a fetus? At what point is the potential for human life extinguished? At this stage the pluripotent cells while able to form almost every human tissue, cannot for a placenta. Therefore if you were to place the cells into another woman?s uterus a fetus would not develop. From this point the pluripotent cells further specialize and become the cells that create heat tissue or brain tissue etc. We need to get a line the complex events that occur at this stage of development. There are g enes referred to as ? finding making? genes. These genes direct how and what the pluripotent cells become. Now I will get into the affirmable benefits of Stem Cell research. Once we learn how the decision making genes work we can then begin to use the pluripotent cells to create the typed of tissues needed to treat patients with conglomerate types of sickness 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 adult stems cells we should be able to proceed quickly. Stem cell research is incredibly important. We as a civilization are standing on the brink 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 release for us? This research has the ability to change out culture, like the discovery of fire and the harnessing of electricit y. We can?t let it slip away.Works ConsultedAdult Stem Cells May be Redefinable. 24.
