After a baby is delivered, the mother's body releases the placenta, the
temporary organ that transferred oxygen and nutrients to the baby while in the
mother's uterus. Until recently, in most cases the umbilical cord and placenta
were discarded after birth without a second thought. But during the 1970s,
researchers discovered that umbilical cord blood could supply the same kinds of
blood-forming (hematopoietic) stem cells as a bone marrow donor. And so,
umbilical cord blood began to be collected and stored.
What are blood-forming stem cells? These are primitive (early) cells found
primarily in the bone marrow that are capable of developing into the three types
of mature blood cells present in our blood - red blood cells, white blood cells,
and platelets. Cord-blood stem cells may also have the potential to give rise to
other cell types in the body.
Some serious illnesses (such as certain childhood cancers, blood diseases, and
immune system disorders) require radiation and chemotherapy treatments to kill
diseased cells in the body. Unfortunately, these treatments also kill many
"good" cells along with the bad, including healthy stem cells that live in the
bone marrow.
Depending on the type of disease and treatment needed, some children need a bone
marrow transplant (from a donor whose marrow cells closely match their own).
Blood-forming stem cells from the donor are transplanted into the child who is
ill, and those cells go on to manufacture new, healthy blood cells and enhance
the child's blood-producing and immune system capability |
