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.
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.
After a baby is born, cord blood is left in the umbilical cord and placenta. It is relatively easy to collect, with no risk to the mother or baby. It contains haematopoietic (blood) stem cells: rare cells normally found in the bone marrow.
Cord Blood Registry offers two ways to save your newborn’s stem cells, and convenient payment options to fit your family’s needs. CBR recognizes that each family’s budget is unique. As a result, CBR does not take a one-size-fits-all approach to pricing and payments for cord blood and tissue banking. Calculate your stem cell banking costs and CBR will recommend payment plans that may fit your family’s budget.
There is little doubt that scientists believe umbilical cord blood stem cells hold promise for the future. Cord blood stem cells are already used to treat blood disorders such as aplastic anemia, and research is underway to determine if they can treat other more common conditions like type 1 diabetes. But many experts question whether many companies’s marketing materials confuse or even mislead parents about the usefulness of private banking.
Unlike other banks, CBR uses a seamless cryobag for storage. The seamless construction decreases the potential for breakage that can occur in traditional, seamed-plastic storage bags. Prior to storage, each cryobag is placed in a second overwrap layer of plastic, which is hermetically sealed as an extra precaution against possible cross contamination by current and yet unidentified pathogens that may be discovered in the future. CBR stores the stem cells in vaults, called dewars, specially designed for long-term cryostorage. The cord blood units are suspended above a pool of liquid nitrogen that creates a vapor-phase environment kept at minus 196 degrees Celsius. This keeps the units as cold as liquid nitrogen without immersing them in liquid, which can enable cross-contamination. Cryopreserved cord blood stem cells have proven viable after more than 20 years of storage, and research suggests they should remain viable indefinitely.
There are a number of different processing methods out there for a cord blood bank to use, and the processing method can ultimately affect the purity of the final product, which we’ll explain in a minute. Once the stem and immune system cells have been isolated and extracted from the plasma and red blood cell, they are mixed with a cryo-protectant and stored in a cryo-bag. We overwrap our bags for added protection and use a technique called “controlled-rate freezing” to prepare the cells for long-term storage. The overwrapped cryo-bag is housed in a protective metal cassette and placed in vapor-phase liquid nitrogen freezer for long-term preservation.

If a sibling of a child whose cord blood you banked needs a transplant, then your chances of a match will be far higher than turning to the public. However, the safest bet is to bank the cord blood of all your children, safeguarding them against a number of diseases and ensuring a genetic match if necessary.
Chemotherapy and radiation therapy generally affect cells that divide rapidly. They are used to treat cancer because cancer cells divide more often than most healthy cells. However, because bone marrow cells also divide frequently, high-dose treatments can severely damage or destroy the patient’s bone marrow. Without healthy bone marrow, the patient is no longer able to make the blood cells needed to carry oxygen, fight infection, and prevent bleeding. BMT and PBSCT replace stem cells destroyed by treatment. The healthy, transplanted stem cells can restore the bone marrow’s ability to produce the blood cells the patient needs.
Once it arrives at the storage facility, the cord blood will be processed and placed in storage. The cord blood will either be completely immersed in liquid nitrogen or it will be stored in nitrogen vapor.
ViaCord’s Lab is FDA registered, AABB accredited, CLIA certified and equipped with the same freezers used by major research institutions such as Centers for Disease Control and Prevention and the National Institutes of Health.

Cord blood cannot be used if the donor (baby) contains the same genetic illness as the recipient. Most cord blood banks glaze over this, but it is important to understand that the odds of using cord blood for the same child are much lower than the odds of using them for a sibling.
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.

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.
Families have the additional option of storing a section of the umbilical cord, which is rich in unique and powerful stem cells that may help repair and heal the body in different ways than stem cells derived from cord blood.
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.”
Yes, if you have any sick children who could benefit from umbilical cord blood. Public banks such as Carolinas Cord Bank at Duke University and private banks such as FamilyCord in Los Angeles offer programs in which the bank will assist with cord blood processing and storage if your baby has a biological sibling with certain diseases. FamilyCord will provide free cord blood storage for one year. See a list of banks with these programs at parentsguidecordblood.org/help.php.
Certain public cord blood banks let you mail in your cord blood. You have to decide before the birth if you want to donate your cord blood. If the hospital where you’re delivering doesn’t accept donations, you can contact a lab that offers a mail-in delivery program. After you’ve passed the lab’s screening process, they’ll send you a kit that you can use to package your blood and mail it in, explains Frances Verter, Ph.D., founder and director of Parent’s Guide to Cord Blood Foundation (parentsguidecordblood.org), a nonprofit dedicated to educating parents about cord blood donation and cord blood therapists.
There are two main types of cord blood banks: public and private. Public cord blood banks are usually nonprofit companies that store your donated cord blood for free, to be used for any sick child in another family or for research purposes, so accessing and using your own cord blood is not guaranteed. Private cord blood banks are companies that require a registration fee (plus annual storage fees) for your cord blood, but it is saved specifically for your own family, so you’ll have ready access to it.
The evolution of stem cell therapies has paved the way for further research being conducted through FDA-regulated clinical trials to uncover their potential in regenerative medicine applications. Cord Blood Registry is the first family newborn stem cell company to partner with leading research institutions to establish FDA-regulated clinical trials exploring the potential regenerative ability of cord blood stem cells to help treat conditions that have no cure today, including: acquired hearing loss, autism, cerebral palsy, and pediatric stroke. In fact, 73% of the stem cell units released by CBR have been used for experimental regenerative therapies – more than any other family cord blood bank in the world.
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.
The stem cells used for autologous transplantation must be relatively free of cancer cells. The harvested cells can sometimes be treated before transplantation in a process known as “purging” to get rid of cancer cells. This process can remove some cancer cells from the harvested cells and minimize the chance that cancer will come back. Because purging may damage some healthy stem cells, more cells are obtained from the patient before the transplant so that enough healthy stem cells will remain after purging.
Beyond these blood-related disorders, the therapeutic potential of umbilical cord blood stem cells is unclear. No therapies for non-blood-related diseases have yet been developed using HSCs from either cord blood or adult bone marrow. There have been several reports suggesting that umbilical cord blood contains other types of stem cells that are able to produce cells from other tissues, such as nerve cells. Some other reports claim that umbilical cord blood contains embryonic stem cell-like cells. However, these findings are highly controversial among scientists and are not widely accepted.
Because only a small amount of bone marrow is removed, donating usually does not pose any significant problems for the donor. The most serious risk associated with donating bone marrow involves the use of anesthesia during the procedure.
One reason BMT and PBSCT are used in cancer treatment is to make it possible for patients to receive very high doses of chemotherapy and/or radiation therapy. To understand more about why BMT and PBSCT are used, it is helpful to understand how chemotherapy and radiation therapy work.
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).
Potential long-term risks include complications of the pretransplant chemotherapy and radiation therapy, such as infertility (the inability to produce children); cataracts (clouding of the lens of the eye, which causes loss of vision); secondary (new) cancers; and damage to the liver, kidneys, lungs, and/or heart.
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.
