Stem Cell Research - Assignment Example The fact that stem cells are undifferentiated makes it easy to program them into any cell of the body or protein. This creates hope for the people with terminal and previously incurable diseases for example diabetes. Stem cells are pluripotent cells, which are not specialized. In embryos, the stem cells differentiate into the different organs of the body. In adults, stem cells are important in the repair mechanism, which replaces the damaged cells of the various organs and tissues of the body (National Institutes of Health, 2009). Stem cells divide continuously as long as a person is alive. The number of stem cells decreases with age. In this case, embryos have many stem cells, children lower stem cells but higher than the number in adults. Reduction in number of stem cells with progression in age is due to the specialization of the cells by forming tissues and organs. It is no wonder research focuses more on the embryonic stem cells. They are easy to obtain and easy to work with as many researchers confirm. The controversy of obtaining stem cells from embryos made scientists to focus on obtaining these important cells from the Umbilical cord with the authorization of parents to the child born ( Bethesda, 2013). . Stem cells have two unique properties. One, they are not differentiated and can renew themselves even after a long period of inactivity. Second, stem cells can form any protein or organs of the body when induced under specific conditions (National Institutes of Health, 2009). Scientific research implies that different organs of the body develop at varying conditions. It is also possible to induce to perform certain functions of the body organs. Stem cells are readily available in embryos especially in the 5th to 8th day after fertilization of the ova and subsequent formation of the zygote (Cox, 2012). In adults however, stem cells are restricted to the bone marrow and certain
