Umbilical cord blood is human blood from the placenta and umbilical cord that is rich in hematopoietic stem cells. Cord blood is collected after the umbilical cord has been detached from the newborn, and utilized as a source of stem cells for transplantation.
Cord blood is stored by both public and private cord blood banks. Public cord blood banks store cord blood for the benefit of the general public, and most U.S. banks coordinate matching cord blood to patients through the National Marrow Donor Program (NMDP).
Private cord blood banks are for-profit organizations that store cord blood for the exclusive use of the donor or donor's relatives.
Public cord blood banking is strongly supported by the medical community. However, private cord blood banking is generally not recommended unless there is a family history of specific genetic diseases. Private banking is unlawful in France and Italy, and opposed by the European Group on Ethics in Science and New Technologies.
Properties
Cord blood stem cells are more proliferate and have a higher chance of matching family members than stem cells from bone marrow. Fathers have a 25% chance of matching their child's cord blood stem cells. Siblings have a 25% chance of being a perfect cord blood match.
