You can check the status of your child’s cord blood unit any time by contacting the public bank. In most cases, the parents won’t have much control over any donated stem cells, so you probably won’t hear much from the storage facility. They may keep you updated if your cells are being used in a patient or clinical trial, but this is up to the bank. By signing the consent form, you are giving the bank full rights to use your child’s cord blood in any patient or clinical trial available.
When an immediate family member has a disease that requires a stem cell transplant, cord blood from a newborn baby in the family may be the best option. There is a 25% chance, for example, that cord blood will be a perfect match for a sibling, because each child shares one of its two HLA genes with each parent. Occasionally cord blood will be a good match for a parent if, by chance, both parents share some of the six HLA antigens. The baby’s cord blood is less likely to be a good match for more distant relatives. The inventories of unrelated cord blood units in public cord blood banks are more likely to provide appropriate matches for parents and distant relatives, as well as for siblings that do not match.
Remaining in the umbilical cord and placenta is approx. 40–120 milliliters of cord blood. The healthcare provider will extract the cord blood from the umbilical cord at no risk or harm to the baby or mother.
The other way the body creates more cells is through its stem cells, and stem cells do things a little differently. They undergo what is called asymmetric division, forming not one but two daughter cells: one cell often an exact replica of itself, a new stem cell with a relatively clean slate, and another stem cell that is ready to turn into a specific type of cell. This trait is known as self-renewal and allows stem cells to proliferate, or reproduce rapidly.
In this way, cord blood offers a useful alternative to bone marrow transplants for some patients. It is easier to collect than bone marrow and can be stored frozen until it is needed. It also seems to be less likely than bone marrow to cause immune rejection or complications such as Graft versus Host Disease. This means that cord blood does not need to be as perfectly matched to the patient as bone marrow (though some matching is still necessary).
A major limitation of cord blood transplantation is that the blood obtained from a single umbilical cord does not contain as many haematopoeitic stem cells as a bone marrow donation. Scientists believe this is the main reason that treating adult patients with cord blood is so difficult: adults are larger and need more HSCs than children. A transplant containing too few HSCs may fail or could lead to slow formation of new blood in the body in the early days after transplantation. This serious complication has been partially overcome by transplanting blood from two umbilical cords into larger children and adults. Results of clinical trials into double cord blood transplants (in place of bone marrow transplants) have shown the technique to be very successful. Some researchers have also tried to increase the total number of HSCs obtained from each umbilical cord by collecting additional blood from the placenta.
The main reason for this requirement is to give the cord blood bank enough time to complete the enrollment process. For the safety of any person who might receive the cord blood donation, the mother must pass a health history screening. And for ethical reasons, the mother must give informed consent.
After your baby is born, the umbilical cord and placenta are usually thrown away. Because you are choosing to donate, the blood left in the umbilical cord and placenta will be collected and tested. Cord blood that meets standards for transplant will be stored at the public cord blood bank until needed by a patient. (It is not saved for your family.)

Mothers and families can donate blood from their child’s umbilical cord, which contains valuable stem cells used in the treatment of over 80 diseases. There are over half a million donated cord blood units around the world, with thousands more added every year.
The procedure for peripheral blood harvesting is easier on the patient than a bone marrow transplant, and stem cell transplants are faster. However, the chances for graft-versus-host disease, where donated cells attack the patient’s body, are much higher after a peripheral blood transplant.
Your adult cells have one disadvantage to cord blood cells – they cannot change their cell type. When stem cells from cord blood and tissue are transplanted, they adjust to fit the individual patient and replace damaged cells. Adult stem cells are also older, which means they have been exposed to disease, and may damage patients after the transplant. Compared to cord blood cells, adult cells have a higher chance for graft-versus-host disease.

For example, in the UK the NHS Cord Blood Bank has been collecting and banking altruistically donated umbilical cord blood since 1996. The cord blood in public banks like this is stored indefinitely for possible transplant, and is available for any patient that needs this special tissue type. There is no charge to the donor but the blood is not stored specifically for that person or their family.
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.
However, cord blood transplants also have limitations. Treatment of adults with cord blood typically requires two units of cord blood to treat one adult. Clinical trials using “double cord blood transplantation” for adults have demonstrated outcomes similar to use of other sources of HSCs, such as bone marrow or mobilized peripheral blood. Current studies are being done to expand a single cord blood unit for use in adults. Cord blood can also only be used to treat blood diseases. No therapies for non-blood-related diseases have yet been developed using HSCs from either cord blood or adult bone marrow.
In March 2004, the European Union Group on Ethics (EGE) has issued Opinion No.19 titled Ethical Aspects of Umbilical Cord Blood Banking. The EGE concluded that “[t]he legitimacy of commercial cord blood banks for autologous use should be questioned as they sell a service, which has presently, no real use regarding therapeutic options. Thus they promise more than they can deliver. The activities of such banks raise serious ethical criticisms.”
If you’re looking to attain cord blood from a public bank, be aware that matched cord blood, as with bone marrow, can be difficult to obtain through a public cord blood bank. Once a match is ascertained, it may take valuable weeks, even months, to retrieve the match, and the cost of acquiring the cord blood from a public bank can be upwards of $40,000. When the newborn’s umbilical cord blood is banked privately, they can be retrieved quickly, and since the parents own the cord blood, banks can perform the retrieval free of charge.

The proteins stem from three HLA genes, and you inherit one HLA from each parent, or half your HLA markers from your mother and half from your father. This gives siblings a 25 percent chance of being a perfect match, a 50 percent chance of being a partial match and another one-in-four chance of not being a match at all. Unfortunately, about seven out 10 patients who need a transplant don’t have a suitable donor in their family. They can either rely on their own stem cells, isolated before treatment or previously preserved, or try to find a match through a public donor.
Since most banks require mothers to sign up for donation between the 28th and 34th week of pregnancy, families must decide to donate ahead of time. If you are considering a public bank for your child’s cord blood, contact the bank and make sure you still have time.
Make sure you meet a few basic guidelines for public banking. Your doctor will give you an advanced blood test after giving birth, but there are a few basic requirements you have to meet before signing up. The requirements are different for each bank, but you can see our basic list of public banking requirements here.
A stem cell has the potential to become one of many different types of cells. Stem cells are unique cells: They have the ability to become many different types of cells, and they can replicate rapidly. Stem cells play a huge part in the body’s healing process, and the introduction of new stem cells has always showed great promise in the treatment of many conditions. It wasn’t until we found out where and how to isolate these cells that we started using them for transplants. Although a person’s own stem cells are always 100 percent compatible, there are risks in using someone else’s stem cells, especially if the donor and recipient are not immediately related. The discovery of certain markers allows us to see how compatible a donor’s and host’s cells will be. The relatively recent discovery of stem cells in the umbilical cord’s blood has proven advantageous over acquiring stem cells from other sources. Researchers are currently conducting clinical trials with stem cells, adding to the growing list of 80 diseases which they can treat.
The term “cord blood” is used for the blood remaining in the umbilical cord and the placenta after the birth of a baby. Cord Blood contains stem cells that can grow into blood and immune system cells, as well as other types of cells. Today cord blood is often used as a substitute for bone marrow in stem cell transplants. There are over 80 diseases treated this way, including cancers, blood disorders, genetic and metabolic diseases.
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.
Florida Hospital for Children is conducting an FDA-regulated phase I clinical trial to investigate the use of a child’s stem cells derived from their own cord blood as a treatment for acquired sensorineural hearing loss.
In a report to the HRSA Advisory Council, scientists estimated that the chances of a pediatric patient finding a cord blood donor in the existing Be the Match registry are over 90 percent for almost all ethnic groups.
Much research is focused on trying to increase the number of HSCs that can be obtained from one cord blood sample by growing and multiplying the cells in the laboratory. This is known as “ex vivo expansion”. Several preliminary clinical trials using this technique are underway. The results so far are mixed: some results suggest that ex vivo expansion reduces the time taken for new blood cells to appear in the body after transplantation; however, adult patients still appear to need blood from two umbilical cords. More research is needed to understand whether there is a real benefit for patients, and this approach has yet to be approved for routine clinical use.
Stem cells from cord blood can be given to more people than those from bone marrow. More matches are possible when a cord blood transplant is used than when a bone marrow transplant is used. In addition, the stem cells in cord blood are less likely to cause rejection than those in bone marrow.
