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

What You Should Know about theme Cells A outlet of extended scientific and ethical count in our society as of late has been the question of Stem Cell explore. Going down this passage could yield unprecedented medical leaps in treatment and prevention that care for get out be able to offer. Before I address the debate of whether or not Stem Cell search should be done, I want to first explain to my readers what stem mobile phones are, how they come to be and what we shag use them for. We must first start with the different types of cells, I will explain them as I say you through part of the foetal 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 burn down pay off anything within the charitable being body. After four days the totipotent cell begins to specialize by becoming a blastocyst. The blastocyst contains an outer layer of cells and an inner cell mass. The outer l ayer of cells will become 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 merciful body. The inner cell mass cannot create a placenta. Since it cannot construct 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 concerned in. One part of Stem Cell debate is the question of when is a fetus a fetus? At what bear down 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(prenominal) 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 understand the complex events that surpass at this stage of development. There are genes referred to as ?decision devising? genes. These genes direct 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 then begin to use the pluripotent cells to create the typed of tissues needed to treat patients with various(a) types of sickness and disease. There is a bonus here as well. origin 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 unveil for us? This research has the ability to reposition out culture, like th e discovery of fire and the harnessing of electricity. We can?t let it slip away.Works ConsultedAdult Stem Cells May be Redefinable. 24. Oct. 2001. British Medical Journal. 24.
