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.
An HLA match helps ensure the body accepts the new cell and the transplant is successful. It also reduces the risk of graft-versus-host disease (GVHD), which is when the transplanted cells attack the recipient’s body. GVHD occurs in 30%–40% of recipients when they aren’t a perfect match but the donor is still related. If the donor and recipient are not related, it increases to a 60%–80% risk. The better the match, the more likely any GVHD symptoms will be mild, if they suffer from GVHD at all. Unfortunately, GVHD can also be deadly.
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.
The mother signs an informed consent which gives a “public” cord blood bank permission to collect the cord blood after birth and to list it on a database that can be searched by doctors on behalf of patients. The cord blood is listed purely by its genetic type, with no information about the identity of the donor. In the United States, Be The Match maintains a national network of public cord blood banks and registered cord blood donations. However, all the donation registries around the world cooperate with each other, so that a patient who one day benefits from your child’s cord blood may come from anywhere. It is truly a gift to the benefit of humankind.
A “tandem transplant” is a type of autologous transplant. This method is being studied in clinical trials for the treatment of several types of cancer, including multiple myeloma and germ cell cancer. During a tandem transplant, a patient receives two sequential courses of high-dose chemotherapy with stem cell transplant. Typically, the two courses are given several weeks to several months apart. Researchers hope that this method can prevent the cancer from recurring (coming back) at a later time.
If you feel that the procedure is too expensive for your child, check with the hospital to see if there are any programs and/or grants available that can assist with the procedure. Some companies do offer financial aid.
Umbilical cord blood is being studied for potential use in a wide variety of life-threatening diseases because it is a rich source of blood stem cells. Transplantation of blood stem cells from umbilical cords has been used successfully to treat several pediatric blood diseases, including sickle cell anemia and cancers such as leukemia and lymphoma. This procedure is still considered investigational. There is currently no solid evidence that umbilical cord blood stem cells have the ability to be transformed into other types of cells, such as replacement nerve tissue or myelin-making cells.

Dennis Michael Todd, PhD, joined Community Blood Services as its President and CEO in 2000. Community Blood Services operates the NJ Cord Blood Bank and The HLA Registry bone marrow donor center, both of which are affiliated with the National Marrow Donor Program (NMDP). In 2012, the blood center expects to distribute over 85,000 units of red cells and 20,000 platelets to hospitals and medical centers throughout northern NJ and Orange County, NY. Dr. Todd is presently a member of the NMDP Executive Committee and Chairman of the Finance Committee. He is a member of the International Society for Cellular Therapy (ISCT), the International Society for Stem Cell Research (ISSCR), the AABB, the American Association of Bioanalysts, and the New Jersey Society of Blood Bank Professionals.
Cord blood (short for umbilical cord blood) is the blood that remains in the umbilical cord and placenta post-delivery. At or near term, there is a maternal–fetal transfer of cells to boost the immune systems of both the mother and baby in preparation for labor. This makes cord blood at the time of delivery a rich source of stem cells and other cells of the immune system. Cord blood banking is the process of collecting the cord blood and extracting and cryogenically freezing its stem cells and other cells of the immune system for potential future medical use.
The body has two ways to create more cells. The first is usually taught in middle school science. Known as cell division, it’s where a cell replicates within its membrane before dividing into two identical cells. Cells do this as needed for regeneration, which we will touch on in a second.
Umbilical cord blood stem cells are different from embryonic stem cells. Umbilical cord blood stem cells are collected by your ob-gyn or a nurse from the umbilical cord after you give birth (but before your placenta is delivered). Embryonic stem cells are collected when a human embryo is destroyed.
Cord Blood Registry’s Newborn Possibilities Program® serves as a catalyst to advance newborn stem cell medicine and science for families that have been identified with a medical need to potentially use newborn stem cells now or in the near future. NPP offers free cord blood and cord tissue processing and five years of storage to qualifying families. To date, the Newborn Possibilities Program has processed and saved stem cells for nearly 6,000 families.
When all the processing and testing is complete, the cord blood stem cells are frozen in cryogenic nitrogen freezers at -196° C until they are requested for patient therapy. Public banks are required to complete the entire laboratory processing and freeze the cord blood stem cells within 48 hours of collection. This is to insure the highest level of stem cell viability. The accreditation agencies allow family banks a window of 72 hours.
*Fee schedule subject to change without notice. If a client has received a kit and discontinues services prior to collection, there is no cancelation fee if the kit is returned unused within two weeks from cancelation notice; otherwise, a $150 kit replacement fee will be assessed. †Additional courier service fee applies for Alaska, Hawai’i and Puerto Rico. ††Applies to one-year plan and promotional plan only.

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.
As a rich source of Hematopoietic Stem Cells (HSCs), cord blood has a number of advantages, including decreased risk of severity of Graft-Versus-Host-Disease (GCHD) and a lower risk of transmissible infectious disease. However, the usefulness of cord blood in stem cell therapy has been limited by the relatively small amount of blood that can be collected using standard procedures. With Cord Blood 2.0™, Americord® is making cord blood banking a lifelong investment with the possibility of treating patients well into adulthood.
Both public and family cord blood banks must register with the US Food and Drug Administration (FDA), and since Oct. 2011 public banks also need to apply for an FDA license. All cord blood banks are required by federal law to test the blood of the mother for infectious diseases. At public banks the screening is usually more extensive, similar to the tests performed when you donate blood. The typical expense to a public bank is $150 per unit.
Umbilical cord blood is blood that remains in the placenta and in the attached umbilical cord after childbirth. Cord blood is collected because it contains stem cells, which can be used to treat hematopoietic and genetic disorders.
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.

So what are your options? You have three choices. One is to store the cord blood with a private company at a cost to you ranging from $1,500 to $2,500 and an annual storage fee in the ballpark of $125. Secondly, you can donate the cord blood to a public bank, if there is one working with your hospital, and your doctor is on board with the idea. There are also public banks that accept mail-in donations, if you register during your second trimester and your doctor is willing to take a short training class on-line. Zero cost to you. The third option is to do nothing and have the cord blood, umbilical cord, and placenta destroyed as medical waste.
Sometimes, not enough cord blood can be collected. This problem can occur if the baby is preterm or if it is decided to delay clamping of the umbilical cord. It also can happen for no apparent reason. If an emergency occurs during delivery, priority is given to caring for you and your baby over collecting cord blood.
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.
Prior to freezing the cells, samples are taken for quality testing. Banks measure the number of cells that are positive for the CD34 marker, a protein that is used to estimate the number of blood-forming stem cells present. Typical cost, $150 to $200 per unit. They also measure the number of nucleated cells, another measure of stem cells, both before and after processing to determine the cell recovery rate. Typical expense, $35 per unit. A portion of the sample is submitted to check that there is no bacterial or fungal contamination. Typical expense, $75 per unit. Public banks will also check the ability of the sample to grow new cells by taking a culture called the CFU assay. Typical expense, $200 to $250 per unit.
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.
Umbilical cord blood is useful for research. For example, researchers are investigating ways to grow and multiply haematopoietic (blood) stem cells from cord blood so that they can be used in more types of treatments and for adult patients as well as children. Cord blood can also be donated altruistically for clinical use. Since 1989, umbilical cord blood transplants have been used to treat children who suffer from leukaemia, anaemias and other blood diseases.
The Cord Blood Registry (CBR) is unique, because it is currently the world’s largest cord blood bank, with over a half-million cord blood and cord tissue units stored to date. This is substantially more than its nearest competitor, ViaCord, which has 350,000 units stored. It was recently acquired by pharmaceutical giant, AMAG Pharmaceuticals, for $700 million in June 2015.
After all is said and done, the cost to collect, test, process and store a donated cord blood collection at a public bank is estimated to be $1,200 to $1,500 dollars for each unit banked. That does not include the expense for the regulatory and quality systems needed to maintain licensure, or the cost of collecting units that are discarded because they don’t meet standards.
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.)
Cord blood is used the same way that hematopoietic stem cell transplantation is used to reconstitute bone marrow following radiation treatment for various blood cancers, and for various forms of anemia. Its efficacy is similar as well.
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 noted earlier, with better matching, there is a greater chance of success and less risk of graft-versus-host disease (GvHD) in any stem cell transplant. With cord blood, the baby’s own cells are always a perfect match and share little risk. When using cord blood across identical twins, there is also a very low chance of GvHD although mutations and biological changes caused by epigenetic factors can occur. Other blood-related family members have a 35%–45% chance of GvHD, and unrelated persons have a 60%–80% chance of suffering from GvHD.

The use of cord blood is determined by the treating physician and is influenced by many factors, including the patient’s medical condition, the characteristics of the sample, and whether the cord blood should come from the patient or an appropriately matched donor. Cord blood has established uses in transplant medicine; however, its use in regenerative medicine is still being researched. There is no guarantee that treatments being studied in the laboratory, clinical trials, or other experimental treatments will be available in the future.
Not all moms can donate their cord blood. Moms who are not eligible are those who: are younger than 18 years old (in most states), have been treated for cancer or have received chemotherapy for another illness, have had malaria in the last three years, or have been treated for a blood disease such as HIV or hepatitis. It’s also not possible to donate cord blood if a mom has delivered her baby prematurely (there may not be enough blood to collect) or delivered multiples (but it’s possible to bank your cord blood of multiples privately).
Private companies offer to store cord blood for anyone who wants it done, whether or not there is any medical reason known to do so at the time. The fee for private storage varies, but averages about $1,500 up front and $100 per year for storage. When there is no one in the family who needs a transplant, private storage of a newborn’s cord blood is done for a purely speculative purpose that some companies have termed “biological insurance.”
In the United States, the Food and Drug Administration regulates any facility that stores cord blood; cord blood intended for use in the person from whom it came is not regulated, but cord blood for use in others is regulated as a drug and as a biologic. Several states also have regulations for cord blood banks.
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.
In order to preserve more types and quantity of umbilical cord stem cells and to maximize possible future health options, Cryo-Cell’s umbilical cord tissue service provides expectant families with the opportunity to cryogenically store their newborn’s umbilical cord tissue cells contained within substantially intact cord tissue. Should umbilical cord tissue cells be considered for potential utilization in a future therapeutic application, further laboratory processing may be necessary. Regarding umbilical cord tissue, all private blood banks’ activities for New York State residents are limited to collection, processing, and long-term storage of umbilical cord tissue stem cells. The possession of a New York State license for such collection, processing and long-term storage does not indicate approval or endorsement of possible future uses or future suitability of these cells.
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.
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.
As a mother-to-be, you can decide that your baby’s first act may be saving another person’s life. You can do this by choosing to donate your baby’s umbilical cord blood to the St. Louis Cord Blood Bank’s First Gift℠ Donation Program.
In Europe and other parts of the world, cord blood banking is more often referred to as stem cell banking. As banking cord blood is designed more to collect the blood-forming stem cells and not the actual blood cells themselves, this term may be more appropriate.
The next step at either a public or family bank is to process the cord blood to separate the blood component holding stem cells. The final product has a volume of 25 milliliters and includes a cryoprotectant which prevents the cells from bursting when frozen. Typical cost, $250 to $300 per unit.
