Since 1988, cord blood transplants have been used to treat over 80 diseases in hospitals around the world. Inherited blood disorders such as sickle cell disease and thalassemia can be cured by cord blood transplant. Over the past decade, clinical trials have been developing cord blood therapies for conditions that affect brain development in early childhood, such as cerebral palsy and autism.
A person will always be a 100% match to his or her cord blood, which is the best fit as there are some conditions that can only be treated with one’s own cord blood stem cells (or a perfect match). However, other conditions can be treated using donor stem cells that are partial genetic matches.
As a result of these advances, it is not unreasonable to hope that cord blood may eventually be used to treat a wider variety of auto-immune and degenerative diseases than is currently being done. If so, (and there are solid indications by researchers that this indeed is the case), it makes perfect sense to consider private cord blood banking.
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.

One of the factors that influence engraftment time is cell dose (Gunning, 2007). Cell dose is directly related to the volume of umbilical cord blood collected. Cell dose refers to the amount of useful stem cells in the sample of blood. Because of the limited volume of cells collected from cord blood, the amount of stem cells in cord blood is approximately 10% less than the amount obtained from bone marrow (Moise, 2005). A single unit of umbilical cord blood usually contains 50 to 200 ml of blood (Gonzalez-Ryan et al., 2000). If an amount of cord blood is less than this minimum volume, the unit is discarded as being unsatisfactory because the cell dose of the sample would not be high enough. Collecting an insufficient volume of cord blood occurs in about 50% or more cases of cord blood collection (Drew, 2005). In general, fewer stem cells are needed for cord blood transplantation, and usually a volume of 50 to 100 ml of cord blood will provide enough of a cell dose for a child or small adult. However, should the recipient need additional stem cells, it is impossible to obtain more stem cells from the infant because the cord blood volume is a limited amount (Percer, 2009).

Cord blood can’t be used to treat everything. If your child is born with a genetic condition such as muscular dystrophy or spina bifida, then the stem cells would have that condition, says Dr. Kurtzberg. But if the cord blood donor is healthy and there is a sibling or another immediate family member who has a genetic condition, the cord blood could be a good match for them.
The “cell recovery rate” is often used to compare processing methods. Expressed as a percentage, the cell recovery rate tells you how many cells are retrieved from the original cord blood collection, once plasma has been removed and red blood cells have been reduced or removed. It is expected that some cells will be lost during processing, and most processing methods have published cell recovery rates between 80%—99%
Osteopetrosis is a genetic disease, so this means that doctors could use a sibling’s cord blood cells to treat Anthony, but they cannot use his own cells because the disease is in every cell in his body. In fact, a majority of the diseases listed in private banking firms’ marketing material as treatable with stem cells are genetic diseases.

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.
Many public banking proponents believe that the greater good to society is to donate your baby’s cord blood stem cells to a public bank for use by someone who may need it, since the likelihood of your baby needing it is very small.
Preserving stem cells does not guarantee that the saved stem cells will be applicable for every situation. Ultimate use will be determined by a physician. Please note: Americord Registry’s activities are limited to collection of umbilical cord tissue from autologous donors. Americord Registry’s possession of a New York State license for such collection does not indicate approval or endorsement of possible future uses or future suitability of cells derived from umbilical cord tissue.
Cord blood banking takes blood from the umbilical cord at the time of birth, and donates it to a public blood bank, or stores it in a private one. Since this blood is so rich in stem cells, which have the potential to become any human cell, it could someday be used as a treatment for the child or their family members.
However, this does not mean more is better. Cord blood banks we reviewed are similar in terms of the quality of services they provided. Affordable services are still available, especially with the different discount options offered by many of the top cord blood banks reviewed.
The syringe or bag should be pre-labeled with a unique number that identifies your baby. Cord blood may only be collected during the first 15 minutes following the birth and should be processed by the laboratory within 48 hours of collection.

As you’re making your cord blood bank comparisons, you may want to factor in the stability of the bank. You’re choosing to store your baby’s cord blood in case it might be needed in the future, so you don’t want the bank to go out of business. Parentsguidecordblood.org offers detailed reviews of every public and private cord blood bank in the U.S.
Recently, it was shown that umbilical cord blood contains a sufficient number of hematopoietic stem cells to be used for transplantation. More than 5500 unrelated-donor cord blood stem cell transplants for a variety of pediatric genetic,22,24–31 hematologic,22,24,25,29,32 immunologic,28 metabolic,26,27,30 and oncologic19,20,33–36 disorders have been performed to date (Table 1). The 1-year survival may be as high as 75% to 90% after sibling HLA-matched cord blood donor stem cell transplantation21,24,29 and 40% to 80% after unrelated cord blood stem cell transplantation.19,20,26,27,33,35,36 Advantages of the use of cord blood include the fact that it is readily available, carries less risk of transmission of blood-borne infectious diseases, and is transplantable across HLA barriers with diminished risk of graft-versus-host disease compared with similarly mismatched stem cells from the peripheral blood or bone marrow of related or unrelated donors.21,34,35,37 Autologous stem cells38,39 have been used for gene therapy in infants with severe combined immunodeficiency, but the appearance of T-lymphocyte leukemia in some patients has indicated the need for more basic research before additional clinical trials of gene therapy can be undertaken.
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.

Families should seriously pursue public banking, donation for research, or private banking instead of discarding their baby’s umbilical cord blood. We aim to be nonpartisan in our dissemination of information, but we believe that discarding your baby’s cord blood is a waste of a once-in-a-lifetime valuable resource.
Tracey said she felt lucky since she banked Anthony’s cord blood with a private company. And Osteopetrosis is one of 80 diseases listed by many cord blood companies in their marketing material as treatable with stem cells.

Cord blood banking is not always cheap. It’s completely free to donate blood to a public cord blood bank, but private banks charge $1,400 to $2,300 for collecting, testing, and registering, plus an annual $95 to $125 storing fee.
A courier collection service. Private banks have a person pick up your donated cord blood, which helps ensure that it arrives at your chosen bank quickly and doesn’t get lost along the way, and that the temperature will remain consistent enough to be accepted at the lab. (Public banks usually send an insulated kit for you to preserve and mail the cord blood.)
Cord blood–banking recruitment practices should be developed with an awareness of the possible emotional vulnerability of pregnant women and their families and friends. Efforts should be made to minimize the effect of this vulnerability on cord blood–banking decisions.
Because of their ability to regenerate, umbilical cord stem cells may provide the answers to conditions such as various forms of heart disease and diabetes. Medical researchers studying umbilical cord blood stem cells have recorded several positive observations in animal studies, including instances where cord blood stem cells have improved vascular functions in injured tissue, as well as blood flow and improved overall heart function.
