Essay Stem Cell Research : Ethics And Moral
Human life would be greatly improved if we, as a society, are able to treat a health problem or prevent a disease process from developing. Human stem cell (hSC) research allows the scientists to intervene and treat a disease at a cellular level.
A stem cell is a primitive cell that can indefinitely replicate making identical copies of itself. These cells can create specialized cells for various body tissues such as: brain tissue, heart muscle, liver tissue and many more. There are two basic types of stem cells: embryonic cells and adult cells. Embryonic cells can only be harvested from pre-implantation embryos such as fertilized eggs left over after IVF procedures in fertilization clinics and also from aborted fetuses. Embryonic cells are especially valuable because they can create cells for almost every tissue in the body, thus they are called “pluripotent”. Adult cells called also “multipotent”, are tissue specific cells and for that reason they are not usually used for research. “They have an important function in tissue replacement and repair.” http://humrep.oxfordjournals.org/content/18/4/672.full.pdf+html.
There are several ethical issues involving stem cell research. A research involving human embryos requires donation of biological materials and thus voluntary informed consent. There is also the issue of protecting the reproductive interests of women in infertility treatment. The embryonic stem cells as a main object of the…
