Good post Stephen!Umbilical cord blood is blood that remains in the placenta and in the attached umbilical cord after childbirth. Cord blood is collected because it contains stem cells, which can be used to treat hematopoietic and genetic disorders.
Definition & Collection
Cord blood is a sample of blood taken from a newborn baby's umbilical cord. It is a rich source of stem cells, which have been used in the treatment of over 75 diseases, including leukemia, lymphoma and anemia. Parents may choose to bank their newborn's cord blood against the possibility that it will be useful in the future, should the child or a related family member fall victim to a disease that is treatable by cord blood stem cells.[1]
Cord blood is obtained by syringing out the placenta through the umbilical cord at the time of childbirth, after the cord has been detached from the newborn.[2] Cord blood is collected because it contains stem cells, including hematopoietic cells, which can be used to treat hematopoietic and genetic disorders. One unit of cord blood generally lacks stem cells in a quantity sufficient to treat an adult patient. The placenta is a much better source of stem cells since it contains up to ten times more than cord blood.[3] Some placental blood may be returned to the neonatal circulation if the umbilical cord is not prematurely clamped.[4] According to Eileen K. Hutton, PhD, and Eman S. Hassan, MBBch, cord clamping should be delayed a minimum of two minutes to prevent anemia over the first three months of life and enriching iron stores and ferritin levels for as long as 6 months. (Ref. "Late vs Early Clamping of the Umbilical Cord in Full-term Neonates," JAMA, March 21, 2007) If the umbilical cord is not clamped, and it is not during an extended-delayed cord clamping protocol, a physiological postnatal occlusion occurs upon interaction with cold air, when the internal gelatinous substance, called Wharton's jelly, swells around the umbilical artery and veins.
Regulation
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. Both public and private cord blood banks are eligible for voluntary accreditation with either the American Association of Blood Banks AABB or the Foundation for the Accreditation of Cellular Therapy FACT. Potential clients can check the current accreditation status of banks from the AABB list of accredited cord blood banks or the FACT search engine of accredited cord blood banks (on their home page). Other countries also have regulations pertaining to cord blood. It is also found out that there are no problems in cord blood donation.[5]
In the United Kingdom, the Human Tissue Authority (www.hta.gov.uk) regulates the cord blood banking.
