When considering cord blood, cord tissue, and placenta tissue banking, you want all of the facts. Americord’s® Cord Blood Comparison Chart gives you information not only on our costs and services, but also on how other companies measure up.
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.
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:
A well-established history. Public banks are affiliated with nonprofit research institutions or hospitals, so they have a better chance of being managed more soundly. For families without a history of diseases treated by cord blood, such as leukemia and sickle cell anemia, the American Academy of Pediatrics (AAP) recommends that cord blood be donated to public banks. Although the AAP states cord blood has been used to treat certain diseases successfully, there isn’t strong evidence to support cord blood banking. If a family does choose to bank cord blood, the AAP recommends public cord blood banking (instead of private) to cut down on expenditures. Private cord blood banks are affiliated with business corporations, so, like any business, they may go under, says William T. Shearer, M.D., Ph.D., professor of Pediatrics and Immunology at Baylor College of Medicine in Houston.
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.
If you want the blood stored, after the birth, the doctor clamps the umbilical cord in two places, about 10 inches apart, and cuts the cord, separating mother from baby. Then she inserts a needle and collects at least 40 milliliters of blood from the cord. The blood is sealed in a bag and sent to a lab or cord blood bank for testing and storage. The process only takes a few minutes and is painless for mother and baby.
Your own cord blood will always be accessible. This applies only if you pay to store your cord blood at a private bank. The blood is reserved for your own family; nobody else can access or use it, and it will never be allotted to another family or be donated to research. If you donate your cord blood to a public bank, on the other hand, anyone who needs compatible cord blood can have it; there’s no guarantee that it will be available if and when your family needs it.
Private banking is an alternative option if you can afford the associated costs and if the family’s history suggests a higher probability of need. Families that are predisposed to certain diseases, that are ethnically mixed, or that include a family member who may need a stem cell transplant should take special care to understand the value the cells may provide.
Extracting stem cells from bone marrow requires surgery under anesthesia; extracting them from the blood requires taking a drug to stimulate their production. And in order to work, these stem cell donations need to come from a person who carries a similar pattern of proteins on the outsides of his or her cells, a molecular calling card known as HLA type. Stem cells found in cord blood don’t need to be as closely matched to work. Because these cells are so flexible, there’s more wiggle room between donor and recipient. That’s particularly good news for people of certain ethnic minorities who often have trouble finding matched stem cell transplant donors.
Prior to transplanting any type of tissue, a “matching” process must occur to increase the success of the transplant and decrease the likelihood that the transplant will be rejected. The rejection of a transplanted tissue is called “graft versus host disease.” The matching process dates back to the late 1950s when the human leukocyte antigens were discovered. There are two classes of human leukocyte antigens. The first class is located on the surface of almost all of the cells with a nucleus within the body of the cell. The second class of human leukocyte antigens is located on the surface of immune cells. Each of the two classes of antigens has three subgroups, creating six antigens for which matching can occur. Thus, a “6 of 6” matching of the antigens represents a “perfect” match. Beyond the matching process, other factors contribute to the success or failure of a stem cell transplant. These factors include, but are not limited to, the age of both the donor and the patient, the type of disease being treated, and the number of stem cells being transplanted (Moise, 2005).

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).
Carolinas Cord Blood Bank, established in 1998, is one of the largest public cord blood banks. It’s affiliated with Duke University, where trials are currently taking place to treat children with cerebral palsy with their own cord blood. Parents can mail in their cord blood donations and receive financial aid if they have a sick older child or family member who can be treated with cord blood.
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.
CBR presented data, in the form of a poster, at the 2008 joint annual meeting of the Center for International Blood and Marrow Transplant Research (CIBMTR) and the American Society of Blood and Marrow Transplants (ASMBT). In the poster, CBR showed results obtained during implementation of the AXP System. The published abstract reported that, under the controlled conditions of the study, the average recovery rate of the mononucleated cell (MNC) population was approximately 99% (specifically 98.7%). The results presented at this meeting are consistent with some of the high MNC recovery rates reported by other groups that have adopted AXP System (Rubinstein P. Cord blood banking for clinical transplantation. Bone Marrow Transplantation. 2009;44:635-642).
To save money, public banks will not even process a cord blood donation unless they know in advance that they are going to keep it. When the collection first arrives at the lab, it is passed through a cell counting machine. Only collections that have at least 900 million nucleated cells are kept. As a result, over 60%-80% of cord blood donations are discarded. The public bank must absorb the expense of the collection kit and delivery charges for discarded blood; typically $100 per unit.
Priority shipping: Cord blood companies that use priority shipping services have families ship them cord blood in a heavily insulated box, which arrives at the cord bank at a certain time, but does not guarantee that the blood remains at a certain temperature.

Cord blood contains stem cells that can save lives. Patients requiring a stem cell transplant will receive cells from one of three sources: bone marrow, circulating blood, or umbilical cord blood. The first two exist in all healthy adults, but cord blood can only be harvested and stored at birth
8. Arthritis. Also called degenerative joint disease, osteoarthritis—the most common form of arthritis—results when protective cartilage in joints wastes away. Once it’s gone, it’s gone for good. Stem cells could change that. Scientists are examining how best to use them to rebuild lost cartilage and repair shot joints.
So what are your options? You have three choices. One is to store the cord blood with a private company at a cost to you ranging from $1,500 to $2,500 and an annual storage fee in the ballpark of $125. Secondly, you can donate the cord blood to a public bank, if there is one working with your hospital, and your doctor is on board with the idea. There are also public banks that accept mail-in donations, if you register during your second trimester and your doctor is willing to take a short training class on-line. Zero cost to you. The third option is to do nothing and have the cord blood, umbilical cord, and placenta destroyed as medical waste.
CBR works with Quick International, a private courier service with 30 years of experience as the market leader in the transport of cord blood, tissue, organs, and the U.S. blood inventory. CBR offers our clients a unique “Track My Kit” system to provide progress updates as the kit containing the cord blood travels to our lab. If it gets lost or damaged while in transit with Quick International, you are covered by a $2,500 warranty.
Finally, there is a significant lack of regulation for umbilical cord blood banking. The lack of quality control, in turn, affects the quality of the specimen available for transplant. Some cord blood banks have submitted to voluntary accreditation, but the process of accreditation varies from bank to bank, whether public or private (McGuckin & Forraz, 2008; Moise, 2005).
Several of these groundbreaking trials only use cord blood stem cells processed by Cord Blood Registry as a way of ensuring consistent quality. That means, saving with Cord Blood Registry gives families access to more uses and treatments.
10. Organ failure. What better way to ease the shortage of organs for transplantation than to grow new ones? That’s what some scientists think, and with stem cells, that vision may become more than a pipe dream. Last year, researchers grew a beating rat heart in the lab with the help of heart cells from newborn rats, preliminary proof of the concept.
Another important disadvantage that is not well understood by the general public is the limited use of an infant’s own umbilical cord blood stem cells later in life, called an autologous transplant. Commercial cord blood banks often advertise the banking of the infant’s cord blood as “biologic insurance.” However, the chance that a child would be able to use his or her own cord blood is extremely small: from a 1:400 to a 1:200,000 chance over the child’s lifetime (Sullivan, 2008). In fact, there are certain instances in which the use of one’s own umbilical cord blood is contraindicated, as in cases when the defect is of a genetic origin. For example, autologous cord blood stem cells cannot be used to treat malignant cancers such as leukemia because the genetic mutations for the cancer already exist on the DNA of the cord blood. Using one’s own stem cells would be, in effect, “contaminating” oneself with the same disease process (Percer, 2009).
There are several advantages of using umbilical cord blood stem cells over bone marrow stem cells for transplants (see Table 2). The first advantage is that umbilical cord blood is relatively easy to collect and process. Once considered a substance to be thrown away after a birth, now the cord blood can be easily saved. After it is saved and sent to a storage facility, the cord blood is quickly available for use within days to weeks after processing. In contrast, bone marrow stem cells can take much longer to find a match, collect the sample, and process. The process for bone marrow transplantation can take from weeks to months. The collection process for cord blood is not painful to either mother or child and can be done either prior to or after the delivery of the placenta (Gonzalez-Ryan, VanSyckle, Coyne, & Glover, 2000; Percer, 2009). Bone marrow transplants, on the other hand, require the donor to be hospitalized, anesthetized, and experience postcollection pain and discomfort. Thus, compared to cord blood, bone marrow collection and transplantation of stem cells are more costly (Drew, 2005; Moise, 2005).
Of particular interest are the flexible hematopoietic stem cells important in that initial transplant. In certain cases, transplanting these cells might be able to reboot a person’s body and get rid of a disease-related defect. Cord blood transplants are similar to bone marrow transplants. A person with leukemia, for instance, might have his own cancerous blood cells wiped out with chemotherapy and radiation. Healthy, non-cancerous stem cells from a donor can then repopulate the blood.
The stored blood can’t always be used, even if the person develops a disease later on, because if the disease was caused by a genetic mutation, it would also be in the stem cells. Current research says the stored blood may only be useful for 15 years.
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).
