Stem cells can save many lives. They are important because of their abilities to regenerate. They can replicate many times and have long term self-renewal. As I said, stem cell have the potential for treating many diseases. Scientist are trying to understand how they form into specialized cell. This is important because medical conditions like cancer and birth defects occur in this process (National Institutes of Health). Scientist also think that they could fix damaged organs and tissue. With the use of pluripotent stem cells; cells that can develop into many different cell types of the body (National Institutes of Health), they can replace the cell of the damaged and dying organ or tissue. We do know enough to treat many other disease. Diseases like Leukemia, Lymphoma, Myeloma, Sickle Cell and many others. These diseases are treated with Hematopoietic stem cells. Lets use Leukemia as an example. Leukemia is the cancer of the blood cells. It usually begins in the bone marrow, producing abnormal growth of white blood cells called leukemia cells. At first the leukemia cells act as normal white blood cells. But as more cells are produced, they can overwhelm the white and, red blood cells, and the platelets from functioning. To treat the leukemia; you have to destroy the leukemia cells, and there are many way to do that. One of those treatments is a stem cell transplant. They use high doses of chemotherapy to kill the leukemia cells. Along with killing the leukemia cells the
