Donating your baby’s cord blood is a wonderful gift. The cells may be the perfect match for someone in desperate need of a stem cell transplant. Unfortunately, cord blood banking is still an extremely new industry; there are only a small handful of public banks in certain regions, and those banks are primarily focused on collecting cord blood stem cells from Hispanic and African American families due to the genetic diversity associated with those families. Please visit http://www.marrow.org/ for a list of public banks with their contact information. One other note: It is also a wonderful gift to be a bone marrow donor, and becoming one is much more available to the public, unlike cord blood banking. Please call your local blood bank or the American Red Cross for additional information on how to become a bone marrow donor.
Quite simply, cord blood is the remaining blood from your baby’s umbilical cord and placenta after birth. Cord blood is loaded with our “stem cells” which are origins of the body’s immune and blood system and maybe the origin of other organs and important systems in the body. Stem cells are important because they have the ability to regenerate into other types of cells in the body.
4. Parkinson’s disease. Stem cells may also help those who suffer from Parkinson’s, a neurodegenerative disorder that can cause tremors, stiffness, and other movement and speech problems. Studies show that embryonic stem cells can give rise to the dopamine-making neurons that Parkinson’s patients lack. When transplanted into rodents with a Parkinson’s-like disorder, those replacement brain cells improved the animals’ motor function.

Cord Blood Registry® (CBR®) is the world’s largest newborn stem cell company. Founded in 1992, CBR is entrusted by parents with storing samples from more than 600,000 children. CBR is dedicated to advancing the clinical application of cord blood and cord tissue stem cells by partnering with institutions to establish FDA-regulated clinical trials for conditions that have no cure today.
Public cord blood banking is free, but you give up your rights to the cord blood stem cells at the time of donation. Just like donating to a blood bank, this means your donation would be owned by the public cord blood bank and not by you. Your donated cord blood stem cells can be used for medical research or could possibly save a life through a transplant. Public cord blood banks release your child’s stem cells when a good match from a registry is identified.1
It depends on who you ask. Although commercial cord blood banks often bill their services as “biological insurance” against future diseases, the blood doesn’t often get used. One study says the chance that a child will use their cord blood over their lifetime is between 1 in 400 and 1 in 200,000.
Private cord blood banking costs $2,000 to $3,000 for the initial fee, and around another $100 per year for storage. While that may seem like a hefty price tag, many expectant parents may see it as an investment in their child’s long-term health.
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.
It’s hard to ignore the ads for cord blood banks, offering a lifetime of protection for your children. If you’re an expectant mom, there’s information coming at you constantly from your doctor’s office, magazines, online, and perhaps even your yoga class.
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.

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.
Targeted efforts should be made to recruit underserved minorities (black, Hispanic, American Indian/Alaska Native individuals) in public cord blood–banking programs to extend to them potential treatments afforded other segments of society.
The main disadvantage of cord blood transplants is that they take at least a week longer to “engraft”, which means repopulate the patient’s blood supply so that cell counts reach minimum acceptable levels. The longer engraftment time is a risk because it leaves the patient vulnerable to a fatal infection for a longer time.
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).
9. Sickle cell anemia. Stem cell researchers are exploring ways to correct numerous blood disorders, including sickle cell anemia. Mice have been cured of the sometimes-deadly condition after receiving transfusions of stem cells made from their own skin cells.
Private cord blood banking can benefit those with a strong family history of certain diseases that harm the blood and immune system, such as leukemia and some cancers, sickle-cell anemia, and some metabolic disorders. Parents who already have a child (in a household with biological siblings) who is sick with one of these diseases have the greatest chance of finding a match with their baby’s cord blood. Parents who have a family history of autism, Alzheimer’s, and type 1 diabetes can benefit from cord blood. Although these diseases aren’t currently treated with umbilical cord steam cells, researchers are exploring ways to treat them (and many more) with cord blood.
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.

Part of the reason for the dominance of these three companies in terms of the total number of units stored is that they are three of the oldest cord blood banks within the U.S., founded in 1992, 1993, and 1989, respectively. All three of these cord blood banks also support cord blood research and clinical trials.
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.

Transplant science is constantly improving. Several companies are bringing to market methods of “expanding” the stem cell population in the laboratory, and these methods are starting to be applied in clinical trials.
Four main types of physical conditions are treated with stem cell transplants: cancers, blood disorders, congenital metabolic disorders, and immunodeficiencies (see Table 1). Examples of cancers that are treated with stem cells are both lymphoma and leukemia. Nonmalignant hemologic disorders also account for a fair share of the recipients of stem cells. Examples of these blood disorders are various types of anemias, such as sickle-cell anemia and Fanconi’s anemia (the first disorder treated with umbilical cord blood stem cells). Stem cells have also been used to treat various metabolic disorders, such as adrenoleukodystrophy. The fourth major category of uses for stem cells is in treating immunodeficiencies, such as Duncan’s disease or adenosine deaminase deficiency (Drew, 2005; Moise, 2005).
Learning about cord blood banking shouldn’t have to be confusing – or boring. Watch one of our stem cell experts who also happens to be a former RN and Labor & Delivery nurse, talk cord blood banking 101. She answers the questions every parent has about banking cord blood and ViaCord.
The procedure of cord clamping can be delayed for a considerable period of time. However, the delay has to be a brief one. It cannot be delayed more than one or two minutes. If the procedure of clamping the cord is delayed for too long, the blood present in the cord might clot and once the blood clots it does not benefit anyone. Neither does it help your baby nor can it be collected for storage.
Cord blood has been shown to contain pluripotent stem cells that have the potential to differentiate into nonhematopoietic tissue, such as cardiac, neurologic, pancreatic, and skin tissue, in vitro.53,54 Extensive laboratory research is taking place to explore the potential therapeutic benefit of cord blood under these circumstances. The results of this research will be necessary to formulate future recommendations regarding autologous cord blood banking.
