Cord Blood also called "placental blood," is the term that is given to the blood that remains in the umbilical cord and placenta after the birth of the baby, and the blood is left behind after the cord has been cut. This blood is discarded with the placenta and umbilical cord at a regular level. But in some cases, when the cord is not prematurely clamped then approximately 180 ml of the blood goes back to the neonatal circulation.
If by any how the umbilical cord is not clamped, then chances brae that a physiological clamping occurs when a form integration is done with cold air, when the internal gelatinous substance, that is given the term as Wharton's jelly swells around the arteries and veins in the umbilical area.
Your baby's cord blood plays a very important role as far as the stem cells are concerned which are genetically unique to your baby and family. These days a lot of discussion has been going on about Harvesting this blood which can either be in the form of a private commercial enterprise or a public medical resource.
Cord blood banking has its pros and cons as far as the medical and parenting community is concerned. If the blood is collected in such a way, then it can take up to 180ml from the baby (sometimes up to half of the total blood volume) which does not sound good as fas as the prenatal medicine is concerned.
The fact is that it is rich in Hematopoietic stem cells. These stem cells can be used in curing various severe diseases in a family. At the same time it ensures safety against diseases and illness in the future.
These days cord blood is stored by both public and private banks. Public banks store by keeping the benefit of general public in mind, and most U.S. banks indulge in the proper coordination in matching the blood to patients through the National Marrow Donor Program (NMDP).
On the other hand, private banks are running solely for the purpose of profit in mind which store blood from the baby for the exclusive use of the donor or donor's relatives.
A Statement given by "The American Academy of Pediatrics 2007" clearly states that: "Physicians should be aware of the unsubstantiated claims of private cord blood banks made to future parents that promise to insure infants or family members against serious illnesses in the future by use of the stem cells contained in cord blood."
