The word cord blood is used for blood that is drawn from the
umbilical cord with the placenta after a baby is born.This was discarded before
as medical waste.Cord blood contains stem cell which may be use in medical treatments
or therapies such as cell transplanting.
A cord blood bank is a
facility which stores umbilical cord blood for future
use. Both private and public cord blood banks have developed since the mid- to
late-1990s in response to the potential for cord blood transplants in treating diseases of the blood and immune systems.
Public banks accept donations to
be used for anyone in need. Unlike private cord blood banking, public cord
blood banking is supported by the medical community. However, there are very strict
regulations which public banks need to follow in order to enable the donated
units to be added to a registry. Generally, an expectant mother interested in
donation should contact the bank before the 34th week of pregnancy. The National Marrow Donor Program has a list of public cord blood banks
on their website. Once the blood is donated, it loses all identifying
information after a short period of initial testing. Families are not able to
retrieve their own blood after it has been donated, but, as discussed below, it
is very unlikely that they would be able to use the sample themselves.
Cord blood banking in private banks is a personal choice made by
both parents. Private banks store
cord blood with a link to the identity of the donor, so that the family may retrieve
it later if it is needed,Since this prevent it from any unwanted diseases that can
attack the umbilical cord.The parents
have custody of the cord blood until the child is an adult. The cord blood
might someday be needed by the donor baby, or it could be used by a relative
who is a close enough match to receive a transplant from the donor (typically a
sibling). Private banks charge a fee of around $1000–$2500 to preserve the
harvested cord blood for family biological insurance. Private banks have been
criticized for aggressive marketing campaigns to expectant parents.
In the United States, the Food
and Drug Administration regulates cord blood under the category of “Human Cells,
Tissues, and Cellular and Tissue Based-Products.” The Code of Federal
Regulations under which the FDA regulates public and private cord blood banks
is Title 21 Section 1271. Other countries
also have regulations pertaining to cord blood.
Cord blood contains hematopoietic stem cells, progenitor cells which can form red blood cells, white blood cells and platelets.
Cord blood cells are currently used to treat blood and immune system related
genetic diseases, cancers, and blood disorders. Medical critics of routine cord
blood collection emphasize that, if neonatal cord blood is so physiologically
valuable, it is of great benefit for the neonate to receive upon birth
