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.
Are public banks and family banks the same, except for who may use the cord blood and the cost to the parents? No. Public banks are subject to much higher regulatory requirements, and compliance with regulations carries costs. At a family bank you pay the bank enough to cover the cost of storing your baby’s cord blood, plus they make a profit. When you donate to a public bank, it costs you nothing, but the bank pays more on processing each blood collection than at a family bank. Let’s look at the steps that take place in the laboratory.
Umbilical cord blood stem cells have the unique ability to help rebuild a healthy immune system damaged by disease. Cord blood has been used in transplant medicine for nearly 30 years and can be used in the treatment of nearly 80 different diseases today.1 Over the last few years, cord blood use has expanded beyond transplant medicine into clinical research trials for conditions like autism and brain injuries.
Because identical twins have the same genes, they have the same set of HLA antigens. As a result, the patient’s body will accept a transplant from an identical twin. However, identical twins represent a small number of all births, so syngeneic transplantation is rare.
In addition to the stem cells, researchers are discovering specific uses for the other types of cells in the treatment of certain conditions. Cord blood Treg cells hold potential for preventing graft-versus-host disease in stem cell transplantations and ameliorating the effects of autoimmune diseases such as diabetes, rheumatoid arthritis and multiple sclerosis. Cord blood natural killer cells also hold future potential. These cells have been programmed to target specific cancers and tumors in clinical trials. This could make them exceptionally strong candidates for chronic or treatment-resistant cases of cancer.
The stem cells used in PBSCT come from the bloodstream. A process called apheresis or leukapheresis is used to obtain PBSCs for transplantation. For 4 or 5 days before apheresis, the donor may be given a medication to increase the number of stem cells released into the bloodstream. In apheresis, blood is removed through a large vein in the arm or a central venous catheter (a flexible tube that is placed in a large vein in the neck, chest, or groin area). The blood goes through a machine that removes the stem cells. The blood is then returned to the donor and the collected cells are stored. Apheresis typically takes 4 to 6 hours. The stem cells are then frozen until they are given to the recipient.
Patients with leukemia, lymphoma, or certain inherited metabolic or immune system disorders have diseased blood-forming cells. For some patients, an umbilical cord blood or bone marrow transplant (also called a BMT) may be their best treatment option.
There are some hospitals that have dedicated collections staff who can process mothers at the last minute when they arrive to deliver the baby. However, in the United States that is the exception to the rule.
However, parents should know that a child’s own cord blood (stored at birth), would rarely be suitable for a transplant today. It could not be used at present to treat genetic diseases, for example, because the cord blood stem cells carry the same affected genes and. if transplanted, would confer the same condition to the recipient. (See the story of Anthony Dones.) In addition, most transplant physicians would not use a child’s own cord blood to treat leukemia. There are two reasons why the child’s own cord blood is not safe as a transplant source. First, in most cases of childhood leukemia, cells carrying the leukemic mutation are already present at birth and can be demonstrated in the cord blood. Thus, pre-leukemic cells may be given back with the transplant, since there is no effective way to remove them (purge) today. Second, in a child with leukemia, the immune system has already failed to prevent leukemia. Since cord blood from the same child re-establishes the child’s own immune system, doctors fear it would have a poor anti-leukemia effect.
CBR created the world’s only collection device designed specifically for cord blood stem cells. CBR has the highest average published cell recovery rate in the industry – 99% – resulting in the capture of 20% more of the most important cells than other common processing methods.
Most cells can make copies only of themselves. For example, a skin cell only can make another skin cell. Hematopoietic stem cells, however, can mature into different types of blood cells in the body. Hematopoietic stem cells also are found in blood and bone marrow in adults and children.
The major risk of both treatments is an increased susceptibility to infection and bleeding as a result of the high-dose cancer treatment. Doctors may give the patient antibiotics to prevent or treat infection. They may also give the patient transfusions of platelets to prevent bleeding and red blood cells to treat anemia. Patients who undergo BMT and PBSCT may experience short-term side effects such as nausea, vomiting, fatigue, loss of appetite, mouth sores, hair loss, and skin reactions.
Your baby’s newborn stem cells are transported to our banking facilities by our medical courier partner, and you can receive tracking updates. Each sample is processed and stored with great care at our laboratory in Tucson, Arizona. CBR’s Quality Standard means we test every cord blood sample for specific quality metrics.
In an allogenic transplant, another person’s stem cells are used to treat a child’s disease. This kind of transplant is more likely to be done than an autologous transplant. In an allogenic transplant, the donor can be a relative or be unrelated to the child. For an allogenic transplant to work, there has to be a good match between donor and recipient. A donor is a good match when certain things about his or her cells and the recipient’s cells are alike. If the match is not good, the recipient’s immune system may reject the donated cells. If the cells are rejected, the transplant does not work.
There are over 130 public cord blood banks in 35 countries. They are regulated by Governments and adhere to internationally agreed standards regarding safety, sample quality and ethical issues. In the UK, several NHS facilities within the National Blood Service harvest and store altruistically donated umbilical cord blood. Trained staff, working separately from those providing care to the mother and newborn child, collect the cord blood. The mother may consent to donate the blood for research and/or clinical use and the cord blood bank will make the blood available for use as appropriate.
A large challenge facing many areas of medical research and treatments is correcting misinformation. Some companies advertise services to parents suggesting they should pay to freeze their child’s cord blood in a blood bank in case it’s needed later in life. Studies show it is highly unlikely that the cord blood will ever be used for their child. However, clinicians strongly support donating cord blood to public blood banks. This greatly helps increase the supply of cord blood to people who need it.
There is not one right answer. Your family’s medical history and personal preferences will play a major role in this decision process. However, we can help you make sense of the available options. Continue to follow our guide on cord blood to understand what is the best choice for your family.

Cord blood donation doesn’t cost anything for parents. Public cord blood banks pay for everything which includes the collection, testing, and storing of umbilical cord blood. This means that cord blood donation is not possible in every hospital.
In Europe, Canada, and Australia use of cord blood is regulated as well. In the United Kingdom the NHS Cord Blood Bank was set up in 1996 to collect, process, store and supply cord blood; it is a public cord blood bank and part of the NHS.
Upon arrival at CBR’s laboratory, the kit is immediately checked in and inspected. Next, the cord blood unit is tested for sterility, viability, and cell count.

There are no health risks related to cord blood collection. Cord blood is retrieved from the umbilical cord after it has been cut, thus preventing any pain, discomfort, or harm. This process is completely safe.
“This is a medical service that has to be done when your baby’s cells arrive and you certainly want them to be handled by good equipment and good technicians,” says Frances Verter, Ph.D., founder and director of Parent’s Guide to Cord Blood Foundation, a nonprofit dedicated to educating parents about cord blood donation and cord blood therapists. “It’s just not going to be cheap.” Although the American Academy of Pediatrics (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 reduce costs.
The immune system has a way to identify foreign cells; it’s what allows the body to defend itself. So although transplants were proving successful after the first in 1956, they were limited to twins because their shared genetic makeup made them 100 percent compatible. This took a turn in 1958, when scientists discovered a protein present on the surface of almost all cells that lets the body know if the cell is one of its own cells or a foreign cell. In 1973, we finally learned enough about these compatibility markers (called human leukocyte antigens or HLAs) to perform the first unrelated bone marrow transplant.
Umbilical cord blood was once discarded as waste material but is now known to be a useful source of blood stem cells. Cord blood has been used to treat children with certain blood diseases since 1989 and research on using it to treat adults is making progress. So what are the current challenges for cord blood research and how may it be used – now and in the future?
Checked to make sure it has enough blood-forming cells for a transplant. (If there are too few cells, the cord blood unit may be used for research to improve the transplant process for future patients or to investigate new therapies using cord blood, or discarded.)
Frances Verter, PhD, founded the Parent’s Guide to Cord Blood in 1998 and has been a Scientific Advisor to Community Blood Services since 2007. In 2011 the NMDP presented her with their Lifeline Award in recognition of her efforts to improve public education about cord blood donation.
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.
Cord blood transplants aren’t entirely new — they’ve been in use for about 20 years. In fact, the outcome of transplants has improved in the last 10 years, says Joanne Kurtzberg, M.D., director of the pediatric bone marrow and stem cell transplant program at Duke University.

According to Cord Blood Registry, cord blood is defined as “the blood that remains in your baby’s umbilical cord after the cord has been cut, is a rich source of unique stem cells that can be used in medical treatments.” Cord blood has been shown to help treat over 80 diseases, such as leukemia, other cancers, and blood disorders. This cord blood, which can be safely removed from your newborn’s already-cut umbilical cord, can be privately stored for the purpose of possible use in the future for your child or family member. (It can also be donated to a public bank, but this is not widely available)
Cord blood is also being studied as a substitute for normal blood transfusions in the developing world. More research is necessary prior to the generalized utilization of cord blood transfusion.
Cord blood banks may be public or commercial. Public cord blood banks accept donations of cord blood and may provide the donated stem cells to another matched individual in their network. In contrast, commercial cord blood banks will store the cord blood for the family, in case it is needed later for the child or another family member.
Therapies with cord blood have gotten more successful. “The outcomes of cord blood transplants have improved over the past 10 years because researchers and clinicians have learned more about dosing cord blood, picking better matches, and giving the patient better supportive care as they go through the transplant,” says Joanne Kurtzberg, M.D., director of the pediatric bone marrow and stem cell transplant program at Duke University.
