![]() ![]() Thus, advocates believe embryonic stem cell research may aid in developing new, more efficient treatments for severe diseases and ease the pain and suffering of numerous people. The principal argument for embryonic stem cell research is the potential benefit of using human embryonic cells to examine or treat diseases as opposed to somatic (adult) stem cells. ![]() The origin of stem cells themselves encapsulates the controversy: embryonic stem cells, originate from the inner cell mass of a blastocyst, a 5-day pre-implantation embryo. Secondly, stem cells are pluripotent, with the propensity to be induced to become specified tissue or any “organ-specific cells with special functions” depending on exposure to experimental or physiologic conditions, as well as undergo cell division and become cell tissue for different organs. First, they are unspecialized cells, meaning they can undergo cell division and renew themselves even with long periods of inactivity. Human embryonic cells possess the ability to become stem cells, which are used in medical research due to two significant features. Since then, research that utilizes human embryonic cells has been a widely debated, controversial ethical issue. scientists confirmed successful isolation and growth of stems cells obtained from human fetuses and embryos. ![]() The stem cell therapy is still under the process of research and there are a number of things that needs to be established before it used as a treatment line.In November 1998, two teams of U.S. If the cells used in the therapy are embryonic then the disadvantage is that the cells will not be from the same human body and there are chances of rejection.The disadvantage of adult stem cells is that the cells of a particular origin would generate cells only of that type, like brain cells would generate only brain cells and so on.The long term side effects of the therapy are still unknown.The use of the stem cells for research involves the destruction of the blastocytes that are formed from the laboratory fertilization of the human egg. ![]() The cons of the stem cell therapy include the following:
