Cord blood, as defined by the Core Blood Donor Foundation, is the blood that stays in the umbilical cord after birth. The blood is taken from the cord and placenta after the baby is born, so the procedure itself is completely harmless to the baby as well as to the mother.
The Core Blood Donor Foundation states that cord blood is an excellent source of stem cells. Cord blood stem cells can be used to treat leukemia and other cancers in the same way that bone marrow is used, with a much less chance of rejection. So what’s a stem cell? Stem cells are special in that they have the ability to develop into many different types of cells within the body. The National Institute of Health claims that they are a repair feature for the body.
Stem cells that are collected from cord blood can be used to treat several types of disorders. These include several types of anemia, types of leukemia, as well as many inherited diseases.
