My article is about the pros and cons of embryonic and adult stem cells. Embryonic have a greater potential because they can develop into nearly every type of cell in the human body. However, new studies suggest that they could possibly have a greater plasticity than orginally thought. Embryonic stem cells are grown easier and in larger numbers than dult stem cells. An advantage of adult stem cells, however, is that there is less chance of rejection because they are compatible with the person's immune system Embryonic stem cells have a greater chance of rejection which could lead to potential disease. Yet adult stem cells have a greater possibilty for DNA mutations compared to embryonic stem cells. The biggest concern and contreversy lies within the issue of morals and ethics. Adult stem cells are harvested with the consent of the patient whereas embryonic stem cells are harvested by destroying a human embryo. However, the potential is greater is for embryonic stem cells but research for adult stem cells is still being advocated.
