Take a Look at Cord Blood Banking

Even though they provide nutrition to babies in the womb, the umbilical cord and placenta get little attention once they emerge into the world. But medical advances have given many couples a reason to give these often overshadowed tissues a second look.

What Is Cord Blood Banking?

Cord blood banking is a process of collecting potentially lifesaving stem cells from the umbilical cord and placenta and storing them for future use. Stem cells are immature cells that can assume the form of other cells. They can be used to treat several diseases, including leukemia, lymphoma, anemia, and some immune system disorders.

If you choose to bank cord blood cells, you'll need to make arrangements ahead of time, usually about two months before your delivery. Soon after your baby's birth, a nurse or doctor will collect the cord blood and a segment of the cord and make sure it goes to the facility where it will be processed, frozen, and stored.

Why You May Choose Cord Blood Banking

You may consider cord blood banking for any number of reasons. If your family has a history of disease that can be treated with cord blood, you may consider this option in case your child or another family member develops the condition. Or you may choose to bank cord blood just in case your child becomes ill, even if you have no family history. You may also choose to donate cord blood to a public bank to help other families.

Limits of Cord Blood Banking

The primary drawback of cord banking is that it is only beneficial in very rare situations. The likelihood of a child having an illness that would benefit from properly matched banked cord blood is 1 in 2700, though some experts think it is even less useful than that.

Stem cells from cord blood can be used to treat some diseases. If your child is born with a genetic disorder, the cord blood likely contains the same code that caused the problem in the first place. It cannot be used to treat your child, or any other person. Cord blood cells from a healthy infant can be used to treat an ill child, as long as the two are a good match.

The amount of stem cells from a single birth is enough to treat a child or young adult. Full-grown adults typically need more stem cells than are available in cord blood, though it is possible to combine stem cells from more than one birth. Additionally, the efficacy and safety of storing cord blood long enough for a child to become an adult has not been proven.
