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.
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.
In terms of performance, our PrepaCyte-CB processing method has taken the lead. PrepaCyte-CB greatly improves on parents’ returns on investment because it yields the highest number of stem cells while showing the greatest reduction in red blood cells.1–4 Clinical transplant data show that cord blood processed with PrepaCyte-CB engrafts more quickly than other processing methods.7 This means patients may start feeling better more quickly, may spend less time in the hospital and are less likely to suffer from an infection. The ability to get better more quickly and a reduced chance of infection can prove vital in certain cases. Learn more about PrepaCyte®-CB here.
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.
There are some diseases on the list (like neuroblastoma cancer) where a child could use his or her own cord blood. However, most of the diseases on the proven treatment list are inherited genetic diseases. Typically, a child with a genetic disease would require a cord blood unit from a sibling or an unrelated donor.
Private cord blood banking is recommended for families with a history of certain diseases. Specifically, these are families with diseases that harm the blood and immune system, such as leukemia and certain cancers, sickle-cell anemia, and some metabolic disorders. Why? The type of stem cells in cord blood can form all kinds of blood cells that can help treat these diseases.
We believe that every family should have the opportunity to preserve their baby’s newborn stem cells. That’s why CBR offers transparent costs of cord blood banking, and various payment options to fit this important step into almost every family budget.
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.
Cord blood is collected by your obstetrician or the staff at the hospital where you give birth. Not all hospitals offer this service. Some charge a separate fee that may or may not be covered by insurance.

Private or family banks store cord blood for autologous use or directed donation for a family member. Private banks charge a yearly fee for storage. Blood stored in a private bank must meet the same standards as blood stored in a public bank. If you have a family member with a disorder that may potentially be treated with stem cells, some private banks will store the cord blood free of charge.
Donors to public banks must be screened for blood or immune system disorders or other problems. With a cord blood donation, the mother’s blood is tested for genetic disorders and infections, and the cord blood also is tested after it is collected. Once it arrives at the blood bank, the cord blood is “typed.” It is tracked by a computer so that it can be found quickly for any person who matches when needed.
There are around 20 companies in the United States offering public cord blood banking and 34 companies offering private (or family) cord blood banking. Public cord blood banking is completely free (collecting, testing, processing, and storing), but private cord blood banking costs between $1,400 and $2,300 for collecting, testing, and registering, plus between $95 and $125 per year for storing. Both public and private cord blood banks require moms to be tested for various infections (like hepatitis and HIV).
Today, many conditions may be treatable with cord blood as part of a stem cell transplant, including various cancers and blood, immune, and metabolic disorders. Preserving these cells now may provide your family potential treatment options in the future.
To recap, we have certain types of stem cells that can become a variety of different cells—they are like the renaissance men of cells—but there is one more thing that makes stem cells special. This has to do with how they replicate themselves.
Further advancements were made in 1978, when stem cells were discovered in cord blood and in 1988, when cord blood stem cells were first used in a transplant. Stem cells extracted from the umbilical cord blood or tissue have since been shown to be more advantageous than those extracted from other sources such as bone marrow. In many ways, this is because stem cells from the umbilical cord can be considered naïve and immature compared to stem cells from other sources. Cord stem cells haven’t been exposed to disease or environmental pollutants, and they are more accepting of foreign cells. In this case, inexperience makes them stronger.
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.
After your baby is born the umbilical cord will be clamped and cut. Using ViaCord’s collection kit, your medical professional will insert a needle into the umbilical cord and let the remaining blood drain into our collection bag.
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.
Blood from the umbilical cord and placenta is put into a sterile bag. (The blood is put into the bag either before or after the placenta is delivered, depending upon the procedure of the cord blood bank.)
Some controversial studies suggest that cord blood can help treat diseases other than blood diseases, but often these results cannot be reproduced. Researchers are actively investigating if cord blood might be used to treat various other diseases.
A mini-transplant uses lower, less toxic doses of chemotherapy and/or radiation to prepare the patient for an allogeneic transplant. The use of lower doses of anticancer drugs and radiation eliminates some, but not all, of the patient’s bone marrow. It also reduces the number of cancer cells and suppresses the patient’s immune system to prevent rejection of the transplant.
