Stem Cell Ethics The study of stem cells have brought about many recent ethical questions and been a topic in many recent ethical debates. What is all the talk about? What exactly is stem cell research and why does it raise so many ethical questions? Stem cell research is on the forefront of regenerative medicine and biological science. It is the study of certain cells in the inner mass of the embryo that are produced a few days after the embryo forms during the blastocyst stage. They are the most primitive of all human cells. They are undifferentiated cells, which mean the cells are not designated to be any special type of cell, such as a nerve, muscle, or skin cell. The cell's specialization is later influenced by the …show more content…
More research into this procedure would make it more fully understood and reduce the chance that the body's immune system would reject the transplanted cells. Research is being done on animals and has been successful. Studies conducted with rats have indicated that stem cells found in the stem cells found in one tissue were able to produce cells for another type of tissue (Nature). Another experiment was performed on mice, according to the journal "Nature" stem cells from bone marrow were implanted into the heart. The cells that were implanted integrated with the surrounding cells and started to rebuild tissue (Alhous 624). However, due to great genetic differences between animals and humans, actual human stem cell research is needed.
Current research on human adult stem cells only suggests that these cells have potential for use in both research and in the development of cell therapies. For example, there would be many advantages to using adult stem cells for transplantation. If adult stem cells could be isolated from a patient, then allowed to divide and direct their specialization for a specific tissue type, and then transplanted them back into the patient, it is unlikely that such cells would be rejected by the body. The implanted cells would be exactly the same as the donors. With more extensive
