When the medical courier delivers the cord blood collection kit to the cord blood bank, it is quickly processed to ensure the continued viability of the stem cells and immune system cells found in the cord blood. Firstly, a sample of the cord blood is tested for microbiological contamination, and the mother’s blood is tested for infectious diseases. As these tests are being conducted, the cord blood is processed to reduce the number of red blood cells and its total volume and isolate the stem cells and immune cells.
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.
The majority of programs that accept cord blood donations require the mother to sign up in advance. In the united States, the current requirement is to sign up by the 34th week of pregnancy. This cannot be over-stressed; time and time again, mothers who want to donate are turned away because they did not inquire about donation until it was too late.

As cord blood is inter-related to cord blood banking, it is often a catch-all term used for the various cells that are stored. It may be surprising for some parents to learn that stored cord blood contains little of what people think of as “blood,” as the red blood cells (RBCs) can actually be detrimental to a cord blood treatment. (As we’ll discuss later, one of the chief goals of cord blood processing is to greatly reduce the volume of red blood cells in any cord blood collection.)
Current applications for newborn stem cells include treatments for certain cancers and blood, metabolic and immune disorders. Additionally, newborn stem cell preservation has a great potential to benefit the newborn’s immediate family members with stem cell samples preserved in their most pristine state.
Like most transplants, the stem cells must be a genetic match with the patients to be accepted by the body’s immune system. It goes without saying that a patient’s own cord blood will be a 100% match. The second highest chance of a genetic match comes from siblings.
AutoXpress™ Platform (AXP) cord blood processing results in a red-cell reduced stem cell product. Each sample is stored in a cryobag consisting of two compartments (one major and one minor) and two integrally attached segments used for unit testing.
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.
In most cases, the success of allogeneic transplantation depends in part on how well the HLA antigens of the donor’s stem cells match those of the recipient’s stem cells. The higher the number of matching HLA antigens, the greater the chance that the patient’s body will accept the donor’s stem cells. In general, patients are less likely to develop a complication known as graft-versus-host disease (GVHD) if the stem cells of the donor and patient are closely matched.
Some parents-to-be are sold on the advertising that banking their child’s cord blood could potentially treat an array of diseases the child, or his siblings, could encounter in their lives. Other parents-to-be may find all the promises too good to be true.
Medical staff at the public cord blood bank will check to see if you can donate. If you have had a disease that can be given to another person through blood-forming cells, such as hepatitis B, hepatitis C, or HIV (the AIDS virus), you will likely not be able to donate. However, other medical reasons may still allow you to donate, for example, hepatitis A or diabetes only during your pregnancy (gestational diabetes). The staff at the public cord blood bank will tell you.

Generally not. The reason siblings are more likely to match is because they get half of their HLA markers from each parent. Based on the way parents pass on genes, there is a 25 percent chance that two siblings will be a whole match, a 50 percent chance they will be a half match, and a 25 percent chance that they will not be a match at all. It is very rare for a parent to be a match with their own child, and even more rare for a grandparent to be a match.
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.
Some brochures advertising private cord blood banking show children with cerebral palsy, a neurological disorder, who were treated with their own stem cells. In the case of Cord Blood Registry, the company lists all stem cell transplants conducted at Duke University. In a list of individuals treated in their “stem cell therapy data” cerebral palsy is listed. However, transplants were part of an early research study and studies of efficacy are just now underway.
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.
To minimize potential side effects, doctors most often use transplanted stem cells that match the patient’s own stem cells as closely as possible. People have different sets of proteins, called human leukocyte-associated (HLA) antigens, on the surface of their cells. The set of proteins, called the HLA type, is identified by a special blood test.
CBR was the first family bank accredited by AABB (formerly the American Association of Blood Banks) and the company’s quality standards have been recognized through ISO 9001:2008 certification—the global business standard for quality. The Federal Drug Administration (FDA) has issued cord blood regulations, and the states of California, Illinois, Maryland, New York and New Jersey have mandatory licensing for cord blood banking. The stringent laboratory processes, record keeping, quality control and quality assurance of CBR are designed to meet all federal and state guidelines and regulations.
With public cord blood banks, there’s a greater chance that your cord blood will be put to use because it could be given to any child or adult in need, says William T. Shearer, M.D., Ph.D., professor of Pediatrics and Immunology at Baylor College of Medicine in Houston. Cord blood is donated and is put on a national registry, to be made available for any transplant patient. So if your child should need the cord blood later in life, there’s no guarantee you would be able to get it back.
Current research aims to answer these questions in order to establish whether safe and effective treatments for non-blood diseases could be developed in the future using cord blood. An early clinical trial investigating cord blood treatment of childhood type 1 diabetes was unsuccessful. Other very early stage clinical trials are now exploring the use of cord blood transplants to treat children with brain disorders such as cerebral palsy or traumatic brain injury. However, such trials have not yet shown any positive effects and most scientists believe much more laboratory research is needed to understand how cord blood cells behave and whether they may be useful in these kinds of treatments
Marketing materials by Viacord and Cord Blood Registry, the two largest companies, do not mention that cord blood stem cells cannot be used by the child for genetic diseases, although the fine print does state that cord blood may not be effective for all of the listed conditions.
Research is being conducted using cord blood cells to analyze immune response and other factors that may eventually shed light on causes and treatment of MS. However, at present there is no treatment available involving cord blood cells. Nor do we know of any sites that are looking for cord blood specifically for MS research.
The first cord blood banks were private cord blood banks. In fact, Cryo-Cell is the world’s first private cord blood bank. It wasn’t until later that the government realized the need to preserve cord blood for research and public welfare. As a result, 31 states have adopted a law or have a piece of pending legislation that requires or encourages OBGYNs to educate expectant parents about cord blood banking and many states now have publicly held cord blood banks. As a result, parents have the option of banking their baby’s cord blood privately for the exclusive use of the child and the rest of the family or donating the cord blood to a public bank so that it can be used in research or by any patient who is a match and in need.
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).
