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).
Cord blood donation should be discouraged when cord blood stored in a bank is to be directed for later personal or family use, because most conditions that might be helped by cord blood stem cells already exist in the infant’s cord blood (ie, premalignant changes in stem cells). 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. Although not standard of care, directed cord blood banking should be encouraged when there is knowledge of a full sibling in the family with a medical condition (malignant or genetic) that could potentially benefit from cord blood transplantation.

Although cord blood is currently considered discarded human material, it should only be collected for banking with an institutional review board–approved protocol and with signed informed consent from a parent.42,43 Pertinent donor information communicated to the cord blood bank should be kept confidential by the cord blood bank and used only to report important medical information obtained during the cord blood collection, processing, and screening process that is relevant to the safety of the donor and family. If cord blood was collected from a newborn who subsequently developed a genetic, immunologic, or malignant neoplastic disorder, parents should notify the cord blood bank so that the unit is not used for transplantation. All cord blood units banked for potential use should be tested for infectious diseases, similar to those tested in a blood bank, and for hereditary hematologic diseases. The informed consent must contain information pertaining to what tests are to be performed on the cord blood and how the parents will be informed if test results are abnormal. Pediatricians should be aware that legal cases relating to the duty of a physician to warn parents about the risks of inheriting a genetic disease are new and untested. Pediatricians should remain vigilant, because future cases may define who has a legal duty to notify parents about genetic abnormalities identified during cord blood testing. Informed consent should be obtained before the onset of active labor and before cord blood collection.
The stem cells obtained from umbilical cord blood are also less likely than bone marrow stem cells to be rejected in transplants. Considered to be immunologically immature, umbilical cord blood stem cells produce significantly fewer natural killer cells, creating a substantial decrease in rejection. Consequently, cord blood stem cells require less rigorous antigen tissue matching for transplants than bone marrow stem cells (Sullivan, 2008). Research indicates that a mismatch of up to two antigen sites still provides successful clinical outcomes (Ballen, 2006; Fox et al., 2007). In fact, researchers report that the rate of rejection for cord blood stem cell transplants is half the rate of rejection for bone marrow transplants (Ballen et al., 2001). When compared directly in cases of mismatched antigens, there was clearly less rejection in transplants involving cord blood stem cells than bone marrow stem cells (Moise, 2005).
Four main types of physical conditions are treated with stem cell transplants: cancers, blood disorders, congenital metabolic disorders, and immunodeficiencies (see Table 1). Examples of cancers that are treated with stem cells are both lymphoma and leukemia. Nonmalignant hemologic disorders also account for a fair share of the recipients of stem cells. Examples of these blood disorders are various types of anemias, such as sickle-cell anemia and Fanconi’s anemia (the first disorder treated with umbilical cord blood stem cells). Stem cells have also been used to treat various metabolic disorders, such as adrenoleukodystrophy. The fourth major category of uses for stem cells is in treating immunodeficiencies, such as Duncan’s disease or adenosine deaminase deficiency (Drew, 2005; Moise, 2005).
For transplants, the primary advantage of cord blood stem cells over stem cells from adults is that they cause much less graft versus host disease (GvHD). In order to safely transplant adult stem cells, the patient and donor must match over at least 10 of 12 tissue types called Human Leukocyte Antigens (HLA), or 83% HLA match. By comparison, medical outcomes are just as good with cord blood that has a 4 out of 6 or 67% HLA match.
Cord blood transplantation has been shown to be curative in patients with a variety of serious diseases. Physicians should be familiar with the rationale for cord blood banking and with the types of cord blood–banking programs available. Physicians consulted by prospective parents about cord blood banking can provide the following information:
The American Congress of Obstetricians and Gynecologists and the American Academy of Pediatrics don’t recommend routine cord blood storage. The groups say private banks should only be used when there’s a sibling with a medical condition who could benefit from the stem cells. Families are encouraged to donate stem cells to a public bank to help others.

With President Obama’s lifting of the ban on federal funding for embryonic stem cell research, scientists had necessary funding for developing medical treatments, in which case with a new Trump’s administration it might be different now.
Current trials show promise for cord blood in the treatment of strokes, heart disease, diabetes and more. Umbilical cord–derived stem cells, meanwhile, are undergoing clinical trials for the treatment of multiple sclerosis, sports-related injuries and various neurodegenerative diseases including ALS (known also as Lou Gehrig’s disease) and Alzheimer’s.
Refer-a-friend program: The New England Cord Blood Bank gives families $100 for each friend they refer to the company, so customers have further incentive to choose the company for storage and processing.
The procedure of cord clamping can be delayed for a considerable period of time. However, the delay has to be a brief one. It cannot be delayed more than one or two minutes. If the procedure of clamping the cord is delayed for too long, the blood present in the cord might clot and once the blood clots it does not benefit anyone. Neither does it help your baby nor can it be collected for storage.
Direct-donation umbilical cord blood banks function as an amalgamation of public and private banks. Direct-donation banks collect cord blood without charging fees. In addition, they accept autogenous donations and reserve them only for the family, especially for a family whose infant has a sibling with a disorder that may be treated with umbilical cord blood stem cells (Moise, 2005).
Some brochures advertising private cord blood banking show children with cerebral palsy, a neurological disorder, who were treated with their own stem cells. In the case of Cord Blood Registry, the company lists all stem cell transplants conducted at Duke University. In a list of individuals treated in their “stem cell therapy data” cerebral palsy is listed. However, transplants were part of an early research study and studies of efficacy are just now underway.
Why should you consider donating the cord blood to a public bank? Simply because, besides bringing a new life into the world, you could be saving an individual whose best chance at life is a stem cell transplant with your baby’s donated cord blood. This can only happen if you donate and if your baby is a close enough match for a patient in need. If you chose to reserve the cord blood for your family, then siblings who have the same parents have a 25% chance of being an exact match.
Well, this is how the entire procedure of cord blood banking. Right after the blood is extracted, it is sent for to the bank. In the bank, the cord blood is checked, tested, processed and finally preserved. This preservation is ensured by controlled freezing under high end freezing conditions. Certain private banks collect a certain segment of the umbilical cord along with the cord blood. The umbilical cord tissue contains various stem cells that are quite different from the general cord blood cells. Research experts are studying in order to understand the possible use of the stem cells in medicine.

LifebankUSA is the only cord blood banking company to have pioneered the advanced technology to collect additional placental stem cells for today’s treatments, and unique placental stem cells for future medical advancements. We discovered unique stem cells that remained trapped in the blood vessels of the placenta, so we created an innovative retrieval method to collect those cells.

Now when you know what is cord blood, you might be wondering how it is collected. Well, cord blood is collected right after the birth of your little one. The procedure is completely painless and free from risks as well. The procedure is so quick, hassle-free and painless that neither a newborn nor a new mother realizes the entire procedure has taken place. Following is a list of steps depicting how the procedure is actually convened. Read on, to grasp a better insight on cord blood banking and its proceedings.
To begin a discussion of umbilical cord blood banking, it must first be understood that the component from the blood that is salvaged is the stem cells. Stem cells are unspecialized cells that are the basis of all tissue and organ cells of the body. There are three main sources of stem cells in humans: embryonic stem cells, adult stem cells, and umbilical cord stem cells. Embryonic stem cells are generally used in research but not in clinical practice. Adult stem cells are found in various locations in the human body, but they are most commonly found in bone marrow (McGuckin & Forraz, 2008). Over the years, transplants of bone marrow stem cells have been used clinically to treat disease processes in which stem cells are beneficial. Umbilical cord blood stem cells were historically considered a waste product of the birthing process but are now known to have up to 10 times more stem cells than adult bone marrow (Gunning, 2007).
Private cord blood banks store cord blood for you in case your child or someone in your immediate family needs it in the future. These private collections are owned by you and you decide how your baby’s cord blood is used. There are processing and storage fees associated with private cord blood banks.
The blood within your newborn baby’s umbilical cord contains young stem cells that can renew themselves and become specialized. These cord blood stem cells have been proven in treatment to help children replace damaged blood cells with healthy ones and strengthen their immune systems. Cord blood banking is the process of collecting and storing these stem cells for potential medical use.
For much of pregnancy, the umbilical cord is the lifeline of a fetus, tethering it to the placenta. Snaking through the nearly 2-feet-long cord, there’s a vein ferrying nutrients and oxygen from mom’s blood (via the placenta), plus two arteries carrying oxygen- and nutrient-depleted blood from the fetus back to mom. Because mother’s blood and fetal blood don’t actually mix much, the blood in the placenta and umbilical cord at birth belongs mainly to the fetus.
Proponents of cord blood banking are convinced that instead of being medical waste, the fetal cells within are biological gold. In this post, and the two that follow, I’ll take a look at the evidence for those claims, and sort through some of the questions that arise as parents consider whether to bank their baby’s cord blood.
Regulatory agencies (eg, FDA, Federal Trade Commission, and state equivalents of these federal agencies) are encouraged to have an active role in providing oversight of the cord blood program. All cord blood–banking programs should comply with FACT or equivalent accreditation standards.
Private (commercial) cord banks will store the donated blood for use by the donor and family members only. They can be expensive. These banks charge a fee for processing and an annual fee for storage.
You’ve just visited the doctor and the good news is that you’re going to have a baby and everything looks good. Thirty years ago, your doctor may have given you a baby book and information about products that sponsors want you to buy for your new addition. Today, along with pretty much the same materials, you’ll be asked to consider saving the blood of your newborn that’s left over in the umbilical cord and placenta after the delivery. Another big decision, and possibly a costly one.
There are three types of umbilical cord blood banks: private, public, and direct-donation banks. The private bank is a commercial, for-profit entity that often advertises directly to expectant parents. These banks are designed for the sole use of the families who have saved the cord blood. Private banks charge an initial fee for collection and processing and, then, a yearly fee to maintain the specimen. Another fee is often charged when a sample is removed for testing or treatment (Moise, 2005).
To most people, the issue comes down to money. If you had unlimited money, you would spend a few thousand to even miniscually increase the chance of your child enjoying good health. However, since you probably don’t have unlimited money, you will have to decide how to best spend and save for your children’s future. If you invested the Viacord fee of $1550 plus $150 for the courier at your child’s birth in the stock market, you would have $12,210 by the time he turned 21. That would certainly help pay for college or even his medical insurance after he graduated from college. The odds are that your child will need a college education more than an autologous bone marrow transplant. So if you have to choose between one or the other, make the right choice by saving the money for his future.
To explain why cord blood banking is so expensive in the United States, we wrote an article with the CEO of a public cord blood bank that lists the steps in cord blood banking and itemizes the cost of each one.
Marketing materials by Viacord and Cord Blood Registry, the two largest companies, do not mention that cord blood stem cells cannot be used by the child for genetic diseases, although the fine print does state that cord blood may not be effective for all of the listed conditions.
New England Cord Blood Bank was founded in 1971 and is one of the pioneers in processing and cryopreservation of human cells and tissue. The company is continuing to expand its research and development center.
If you do decide to bank your baby’s cord blood, there’s one more thing to keep in mind: It’s best not to make it a last-minute decision. You should coordinate with the bank before your baby is born so nothing is left to chance.
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.
A “clinical trial” is a study in human patients for an emerging therapy that has not been adopted as standard therapy. This website has pages that enable patients to search worldwide for currently recruiting clinical trials with ether cord blood or umbilical cord tissue MSC. The table below checks off all diagnoses that have ever been treated in clinical trials with cord blood or cord tissue, regardless of whether the trials are still open.
