Sources of Stem Cells
Why are cord blood stem cells so valuable?
Blood stem cells, most often found deep in bone marrow, are the factory of the blood system. They continually make new copies of themselves and produce cells that make every other type of blood cell. Stem cells are the key to successful bone marrow transplantations (BMTs) because they continue to manufacture blood cells indefinitely.
Bone marrow transplants can be lifesaving for people with leukemia (cancer of the white blood cells) and other cancers, or for those with serious blood disorders, such as aplastic anemia, in which the body does not produce enough blood cells. Stem cells can help enhance a person’s blood producing capability and immune system that are impaired through an inherited (genetic) defect or that have been severely damaged or deliberately destroyed by cancer treatments. At present, donated bone marrow is the most common source of stem cells. |
