As such, the condition of the patient would become even worse if these cells or organs were transplanted into the patient. The body would detect these transplanted cells as foreign invader cells and would utilize the body's immune system to destroy them. In some cases, massive blood clots in the blood vessels as a result of the body's reaction to these foreign invader cells would prevent a circulation of oxygen to the brain and many vital organs, hence causing suffocation and eventually death to the person. In fact embryonic stem cells were used as a form of treatment for people with Parkinson's disease and instead of getting better, their condition actually worsened and the whole experiment was stopped. We have to ask ourselves, is it really worth sacrificing lives, human lives for the purpose of some fictitious treatment that will never work? No, embryonic stem cell research is unnecessary and deplorable, stem cells should not be used from spare human embryos. .
Secondly, there have already been successes in the area of using adult stem cells from the tissues of the patient themselves. While little to no success have been met with using embryonic stem cells as a form of treatment, adult stem cell treatment have met with resounding success on a regular basis. This is largely due to the fact that adult stem cells are extracted from the patient and this effectively solves the problem of immune rejection as the cells or organs derived from adult stem cells will have the same antigens as the patient itself. Additionally, there can be no moral qualms associated with adult stem cells as extracting adult stem cells does not involve killing any human being. Indeed, adult stem cells have proved to be a far more viable alternative than embryonic stem cells and further research should be directed to this area of treatment rather than to the unreliable embryonic stem cell treatment. One of the successes of adult stem cell treatment was in July 2001 when German doctors reported that a patient's own adult stem cells from bone marrow were used to regenerate damaged tissue from a heart attack the patient had suffered earlier.
