The term “Cord Blood harvesting” has a slightly morbid sound, but in reality, it is a very worthwhile and potentially lifesaving field of medical science. Umbilical Cord blood is blood that remains in the umbilical cord after birth. This umbilical cord blood is full of stem cells, and these powerful cells can be harvested for use in medical testing, or for transplantation into another host. A transplantation of harvested umbilical cord blood can have a profound effect on the recovery of patients with a host of medical conditions such as leukemia, cancers, thalassemia, Diabetes and some other diseases.
With umbilical cord blood harvesting, the harvested cord blood does not come from the newborn baby itself; instead, the cord blood is harvested from the blood that remains in the umbilical cord after birth. Umbilical cord blood is never harvested from either mother or child, but only from the unused blood in the umbilical cord, which would otherwise be discarded waste. The harvesting procedure takes only a few minutes and there is zero danger to either the parent or the baby.
The process for umbilical cord blood harvesting is straightforward: An obstetrician or doctor harvests the umbilical cord blood at the time of the baby’s birth. Timing is very important, as the umbilical cord blood must be harvested quickly so that the cells remain fresh. The harvested umbilical cord blood should preferably be at least 75 mL to make sure that there is enough cord blood and stem cells to be transplanted at a later stage.
After harvesting, the umbilical cord blood is taken to a cord blood bank where it will be tested to make sure that it is clear of disease and other contaminants. Before being frozen, a cryopreservant is added to the cord blood so that the stem cells are able to be frozen without damaging them, after which they are stored in a liquid nitrogen Cord Blood storage tank at –196 Celsius.
Umbilical cord blood stem cells are different from other kinds of cells in a couple of different ways. The first is that umbilical cord blood stem cells are unspecialized cells, which have the ability to renew themselves by cell division, even after significant time has elapsed since they were frozen. The second reason is that in certain situations, and under exacting conditions, the umbilical cord stem cells can become tissue- or organ-specific cells, allowing regeneration of those tissues.
Because of their ability to regenerate, umbilical cord stem cells may provide the answers to conditions such as various forms of heart disease and diabetes. Medical researchers studying umbilical cord blood stem cells have recorded several positive observations in animal studies, including instances where cord blood stem cells have improved vascular functions in injured tissue, as well as blood flow and improved overall heart function.
If you intend donating umbilical cord blood for preservation and later use, you should let your doctor know by your 34th week so that they can help make any arrangements with a cord blood bank. Once you and your doctor have decided on which cord blood bank to use, you will often be sent informational reading materials from the cord blood bank for further education regarding the process of cord blood harvesting.
Prior to the cord blood being harvested you will need to complete a health history questionnaire, and provide a blood sample to check for disease. In most situations, you will also be required to sign a consent form to confirm your intention to have the cord blood harvested.
