Stem Cell Research Stem cells are undifferentiated cells with the ability to change into other cells. They are unspecialized and can renew themselves for long periods during cell division. Under certain conditions, they can actuated to become cells with special functions. There are two different types of stem cells: adult and embryonic. Adult stem cells are undifferentiated cells, found amid differentiated cells in tissues or organs. They are capable of renewing themselves to preserve and restore the tissue they are found in. Embryonic stem cells are extracted from embryos, developed from fertilized eggs.[1] This is where the controversy of stem cells lies. In order to use an embryonic stem cell, the embryo must be killed. In my personal opinion, I do not see a problem with the use of embryonic stem cells, as long as they are donated with permission from the donors. However, I see the use of adult stem cells as more profitable in improving the lives and health of people. Adult stem cells have been found in more tissues than scientists could ever have predicted. Scientists have proof of the existence of stem cells in the brain and heart. Places in which they are also found are: bone marrow, peripheral blood, blood vessels, skeletal muscle, skin, teeth, gut, liver, ovarian epithelium, and testis. Finding these cells in these organs and tissues have led some to ponder whether these cells could be used for transplants. If scientists are able to control the differentiation of stem cells, they could be the foundation for transplantation-based therapies. Bone marrow stromal stem cells are capable of generating bone, cartilage, fat, cells that support the formation of blood, and fibrous connective tissue.[2] Adult stem cells have the potential to change lives for the better, and even save them. Adult stem cells are taken from the patients body, so there are not the
