Some ethical concerns over umbilical cord blood banking warrant mention. As previously stated, the AAP (2007) acknowledges that claims in advertisements for private cord blood banks are not accurate. In fact, some of the statements made by private cord blood banks are outright misleading (Fox et al., 2007), which raises questions about how informed consent for cord blood collection is obtained. Legally, the cord blood belongs to the child, but the consent of the mother alone is usually obtained for collection, and the consent of the father is rarely considered (Ballen, 2006). Because the cord blood now has a “value,” the person who obtains consent and that same person’s professional connection to the private cord blood bank may come into question (Pinch, 2001).

At the end of a recent childbirth class, I found two couples engaged in a lengthy discussion. In the course of the conversation, both couples agreed that their goal was to do the best things for their pregnancy and birth. They were attending childbirth classes to learn how to support normal birth. They each were planning to attend breastfeeding classes. As their conversation continued, the first couple described their decision to bank the umbilical cord blood of their yet unborn daughter. They were adamant that their decision was the best action for them because they had a strong family history of myasthenia gravis. They stated that they had researched the issue by talking to several different cord blood banks, and they had decided on one particular bank because it processed the cord blood without the use of the anticoagulant drug, heparin. The couple went on to parrot back the information that the cord blood bank had told them. It was evident that the first couple wanted what was best for their yet unborn child.
Donating your baby’s cord blood to a public bank is always free. The limitations of the public banking network in the United States are: they only collect donations at large birthing hospitals in ethnically diverse communities, the mother must pass a health screening, they prefer registration by 34 weeks of pregnancy, and they only save the largest cord blood collections. The potential reward of public donation is that your baby could Be The Match to save a life!
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.
Cord blood banks will use some sort of processing method, and the above stats are metrics that we look at for processing efficiency. CBR proactively decided on AXP with dry heparin because we believe that utilizing this combination yields the best sample for our clients
The stem cells from your baby’s cord blood may also be effective in treating certain diseases or conditions of a parent or sibling. Cord blood stem cells have similar ability to treat disease as bone marrow but with significantly less rejection.
An alternative to a related donor involves seeking unrelated HLA-matched adult allogeneic donors outside of the family.2,6,11 There are more than 7 million potential unrelated volunteer adult donors registered in the National Marrow Donor Program registry.17 Although the number of patients who receive unrelated adult allogeneic donor stem cell transplants continues to increase each year, many patients are unable to find a fully matched donor, which diminishes access to transplantation therapy. Nonwhite patients have a lower chance of identifying a fully matched unrelated adult donor because of genetic heterogeneity and lack of nonwhite donors. Over the past decade, unrelated-donor, banked umbilical cord blood has been shown to contain sufficient numbers of stem cells for successful transplantation between unrelated, partially HLA-mismatched individuals.19–23 With advances in the clinical practice of cord blood transplantation, most patients unable to find a fully matched adult donor can identify a partially matched cord blood donor.
In recent years, umbilical cord blood has been used successfully to treat a variety of pediatric genetic, hematologic and oncologic disorders. This advance has resulted in both not-for-profit and for-profit cord blood banking programs. The AAP’s statement is intended to help guide physicians in answering parents’ questions about cord blood banking.
The main disadvantage of cord blood transplants is that they take at least a week longer to “engraft”, which means repopulate the patient’s blood supply so that cell counts reach minimum acceptable levels. The longer engraftment time is a risk because it leaves the patient vulnerable to a fatal infection for a longer time.
Prior to freezing the cells, samples are taken for quality testing. Banks measure the number of cells that are positive for the CD34 marker, a protein that is used to estimate the number of blood-forming stem cells present. Typical cost, $150 to $200 per unit. They also measure the number of nucleated cells, another measure of stem cells, both before and after processing to determine the cell recovery rate. Typical expense, $35 per unit. A portion of the sample is submitted to check that there is no bacterial or fungal contamination. Typical expense, $75 per unit. Public banks will also check the ability of the sample to grow new cells by taking a culture called the CFU assay. Typical expense, $200 to $250 per unit.
Families with a history of diseases can store cord blood in a bank. These families can access it should a person get sick with an immune system or blood disease, like leukemia or sickle-cell anemia, later in life.
Another important consideration for autologous use is that, currently, it is unknown how long umbilical cord blood will maintain its usefulness while frozen. Research indicates that cord blood stem cells can be maintained up to 15 years, but it is unknown if the cells would be preserved over the entire lifetime of a person (Ballen et al., 2001; Hess, 1997). Furthermore, financial costs are associated with maintaining the cord blood over time. Kaimal, Smith, Laros, Caughey, and Cheng (2009) studied the cost-effectiveness of private umbilical cord blood banking for autologous use and concluded that it was not cost-effective in most instances because the chances that it would be used are extremely small.

The blood that remains in the umbilical cord and the placenta after birth is called “cord blood”. Umbilical cord blood, umbilical cord tissue, and the placenta are all very rich sources of newborn stem cells. The stem cells in the after birth are not embryonic. Most of the stem cells in cord blood are blood-forming or hematopoietic stem cells. Most of the stem cells in cord tissue and the placenta are mesenchymal stem cells.
Public cord blood companies are mostly nonprofit companies that are traded publicly, and doctors can utilize matching cord blood in these banks for treating their patients, even if the blood is not their own.
The Cord Blood Registry (CBR) is unique, because it is currently the world’s largest cord blood bank, with over a half-million cord blood and cord tissue units stored to date. This is substantially more than its nearest competitor, ViaCord, which has 350,000 units stored. It was recently acquired by pharmaceutical giant, AMAG Pharmaceuticals, for $700 million in June 2015.
These are diagnoses for which stem cell treatments are being studied either in the laboratory with cell cultures or in animals that mimic the human disease. The experimental therapies are not yet in human clinical trials. In experimental research, it is often not clear whether an eventual therapy, if developed, would be Autologous or Allogeneic.
Hard numbers are tricky to pin down, but between that first transplant in 1988 and 2015, an estimated 35,000 umbilical cord blood transplants had been performed globally. That number includes people treated for leukemia and other types of cancer, blood disorders and immune diseases. And the utility of umbilical cord cells may stretch well beyond the disorders that the cells are currently being used for. “If you read the literature, it’s pretty exciting,” says pediatrician and immunologist William Shearer of Baylor College of Medicine and Texas Children’s Hospital.
You need to plan ahead if you decide to store cord blood. Banks need to be notified four to six weeks before your due date if you’re interested in donating blood. Once you do decide on a public bank, those affiliated with the Be the Match registry (bethematch.org/cord) will cover the costs of collecting, processing, and storing cord blood units.
The most obvious argument against is that the odds of needing cord blood for medical treatment is very, very slim. Below is a news release on a policy published in the July,1999 issue of Pediatrics, the peer-reviewed scientific journal of the American Academy of Pediatrics (AAP):
Medical shipping: Some cord blood companies use medical shipping companies to deliver cord blood; these companies guarantee that cord blood is kept a certain temperature and delivered to the facility by a certain time, typically within 24 hours of collection.
Throughout the last few years, cord blood banking has turned out to be one of the most viable and commendable medical advancements. Wondering what is cord blood? Well, this is the blood extracted from the baby’s umbilical cord. The entire procedure, during which the blood is extracted, turns out to be painless and safe both for the child and the mother. On top of that, the baby, his family members, and many other individuals can enjoy high health benefits from the procedure of cord blood banking. So simply read along to know better about cord blood storage as well as overall cord blood banking procedures.
