Anatomy and Physiology
Sickle cell anemia is defined as being a severe form of the illness anemia, where not enough healthy red blood cells are present to carry the necessary oxygen to the rest of the body (Hwang & Shaparin 2003). Red blood cells in individuals with sickle cell anemia will be rigid and moon-shaped, unlike normal red blood cells that are smooth and round. Because of the shape of the red blood cells with sickle cell anemia, they become sticky and slow or block the flow of blood which ceases the amount of oxygen that can even go to the rest of the body (Bjorklund 2010).
Getting diagnosed with sickle cell anemia can happen as young as right after birth, or even before a baby is born (Peterson 2009; Bloom 1995). In order for this to occur, the fluid surrounding the amniotic sac is tested to watch out for the presences of hemoglobin S. This test is usually done when one or both parents of the unborn child have sickle cell anemia themselves (Bloom 1995). Usually however, a simple blood test is done to check for the presence of hemoglobin S. This is done routinely for all newborns in the United States, and can be done on adults or children (Bloom 1995). If the person tests positive for the presence of hemoglobin S, they will then give further tests in which the blood cells will be examined under a microscope...
In avoiding the current controversy on the morality of embryonic stem cell research, researchers and doctors have resorted to other options (Dobson 2004, National Review 2004). Substitutes like adult stem cells and somatic cell nuclear transfer from placental or umbilical cord stem cells of newborns. Adult stem cells, however, were found to be nearly not as malleable as human embryonic stem cells or those acquired through somatic cell nuclear
