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.
Parents have the option to privately store their newborn’s cord blood stem cells. There are now over a dozen private cord blood banks, and more open every year. Some have their own labs, while others contract with a lab. Cord blood stem cell banking is not a regulated industry; there are no certifications or licensing requirements to open a cord blood bank. Several banks are accredited by the American Association of Blood Banks. Please keep in mind there is a big difference between being accredited by the AABB and being a member of the AABB. To be accredited, the lab must follow strict standards and be inspected by the association.
When researching cord blood banks, make sure they’re registered with the Food and Drug Administration (FDA), and comply with FDA regulations including current good tissue practice regulations, donor screening and testing for infectious diseases. Check for accreditations with American Association of Blood Banks or the Foundation for the Accreditation of Cellular Therapy. Other factors to consider are the bank’s shipping and delivery methods, clinical experience, processing options, payments and costs.
Despite the benefits of using umbilical cord blood stem cells for transplant, the process also has some disadvantages (see Table 3). For stem cell transplants to be successful, measurable signs of engraftment must occur. Engraftment is the opposite of rejection and indicates that the stem cell transplant is “working.” Two measurable signs of engraftment are the recovery of both neutrophil (a type of white blood cell) and platelet (a clotting factor) production. These two clinical signs of recovery take longer to occur in umbilical cord blood stem cell transplants than in bone marrow stem cell transplants. In other words, the lab values for white blood cell production and platelet production take longer to increase after umbilical cord blood stem cell transplants than after bone marrow stem cell transplants (Hess, 1997; Moise, 2005).
M.A.Z.E. Cord Blood Laboratories is an FDA-approved and regulated storage facility that partners with Community Blood Services for processing. The company has processed over 30,000 units of cord blood since opening in 1997.
“Processing” refers to separating the important components of the whole cord blood before cryopreservation. There are many methods used to process cord blood that can achieve the same goal: storing the important cells for potential future use. However, it’s important to point out some differences between methods:
Banking a baby’s blood and stem cells in a cord blood bank is a type of insurance. Ideally, you would not need to access your baby’s stem cells in order to address a medical concern. However, using a cord blood bank can provide peace of mind in knowing that you have a valuable resource if you need it.
Public umbilical cord blood banks accept altruistic donations of cord blood and do not charge donation fees. Donated units are also processed, antigen typed, and frozen, ready for use. Unlike private banks, public banks do not reserve the units for the family that donated them; rather, units are available to the general public. In fact, a family that donates the blood would be no more likely to be a recipient of the blood than anyone else in the general population. Public cord blood banks function much like venous blood banks. The blood is released on an “as-needed” basis, and a processing fee may be charged to recoup some of the cost of storage (Moise, 2005; Percer, 2009).
Many private banking proponents think that by storing your baby’s cord blood stem cells, you are positioning your family with a form of biological insurance in the event that your child or a close family member has a treatable disease.
Right after the cord is clamped and cut, your medical practitioner uses a needle and gets it inserted into the umbilical vein of the cord. Only that part is cut which is still attached to the placenta. High quality and proper needles are used and they do not go anywhere near your baby.
Cryo-Cell, Viacord, and Cord Blood Registry are three of the oldest and largest private cord blood banks in the United States. They’ve been storing cord blood since the early ’90s, and they’re all accredited by the AABB. Cryo-Cell is located in Oldsmar, Florida; Viacord in Cambridge, Massachusetts; and Cord Blood Registry in San Bruno, California. Each of these banks has its own private labs that test for syphilis, HIV, hepatitis, cytomegalovirus, and human T-cell lymphotrophic virus (considered a precursor to leukemia); the testing is included in their registration fee.
The most obvious argument against is that the odds of needing cord blood for medical treatment is very, very slim.  Below is a news release on a policy published in the July,1999 issue of Pediatrics, the peer-reviewed scientific journal of the American Academy of Pediatrics (AAP):
CBR presented data, in the form of a poster, at the 2008 joint annual meeting of the Center for International Blood and Marrow Transplant Research (CIBMTR) and the American Society of Blood and Marrow Transplants (ASMBT). In the poster, CBR showed results obtained during implementation of the AXP System. The published abstract reported that, under the controlled conditions of the study, the average recovery rate of the mononucleated cell (MNC) population was approximately 99% (specifically 98.7%). The results presented at this meeting are consistent with some of the high MNC recovery rates reported by other groups that have adopted AXP System (Rubinstein P. Cord blood banking for clinical transplantation. Bone Marrow Transplantation. 2009;44:635-642).





Options for Umbilical Cord Blood Banking and Donation—As expectant parents, learn how umbilical cord blood can help others through public donation, family (private) cord blood banking, or directed donation for a biological sibling.
The standard used to identify these cord blood banks was the number of cord blood and cord tissue units stored by each company. The purpose of this analysis is to compare pricing and services among the largest cord blood banks within the U.S., the most mature cord blood banking market in the world. These three industry giants also represent several of the largest cord blood banks worldwide.
Cord blood specimens for non-clinical scientific research studies are also available through the Cord Blood Transplantation (COBLT) Study, funded by the National Heart Lung and Blood Institute (NHLBI)
Over 95% of newborns’ cord blood stem cells fall into this category. It is unfortunate that public banking is not readably available and private banking is so expensive. Some industry leaders believe that as the industry grows, banking or donating cord blood will be as common as it is uncommon today.
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.
FACT accredited: Cord blood companies that are FACT accredited have been evaluated by the Foundation for the Accreditation of Cellular Therapy, and they’re found to have met the foundation’s standards of operation.

Patients with leukemia, lymphoma, or certain inherited metabolic or immune system disorders have diseased blood-forming cells. For some patients, an umbilical cord blood or bone marrow transplant (also called a BMT) may be their best treatment option.
The process for umbilical cord blood harvesting is straightforward: An obstetrician or doctor harvests the umbilical cord blood at the time of the baby’s birth. Timing is very important, as the umbilical cord blood must be harvested quickly so that the cells remain fresh. The harvested umbilical cord blood should preferably be at least 75 mL to make sure that there is enough cord blood and stem cells to be transplanted at a later stage.
Cord blood contains stem cells that can save lives.  Patients requiring a stem cell transplant will receive cells from one of three sources: bone marrow, circulating blood, or umbilical cord blood.  The first two exist in all healthy adults, but cord blood can only be harvested and stored at birth
Tracey Dones of Hicksville, N.Y., paid to bank her son Anthony’s cord blood. But four months after he was born, Anthony was diagnosed with osteopetrosis, a rare disease that causes the body to produce excess bone, leads to blindness, and can be fatal if left untreated.

Public cord blood companies are mostly nonprofit companies that are traded publicly, and doctors can utilize matching cord blood in these banks for treating their patients, even if the blood is not their own.
Your own cord blood will always be accessible. This applies only if you pay to store your cord blood at a private bank. The blood is reserved for your own family; nobody else can access or use it, and it will never be allotted to another family or be donated to research. If you donate your cord blood to a public bank, on the other hand, anyone who needs compatible cord blood can have it; there’s no guarantee that it will be available if and when your family needs it.
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.

In the past years, there have been dramatic medical advances in the arena of stem cell research, and more discoveries are announced practically every month. Many doctors and researchers see great potential in the use of stem cells to reverse or cure many severe, life-threatening diseases. With these facts in mind, many parents are choosing to preserve the stems cells found in umbilical cord blood after birth. There are no health risks in doing so. The primary risk is that the $100 yearly fee for storage will be wasted in the event that the stem cells are never needed.
Research on stem cell transplants began in the 1950s, with successful bone marrow transplants occurring in the 1970s, often to treat cancer patients whose own bone marrow was destroyed by chemotherapy and radiation. The first successful umbilical cord blood stem cell transplant was reported as occurring in the late 1980s. The recipient was a 6-year-old American boy from North Carolina who was treated for Fanconi’s anemia (a genetic disorder) at Hospital St. Louis in Paris, France, using cord blood obtained from his younger sister’s birth. Interestingly, more than 20 years after the transplant, this young man is alive and well. Not only did he survive long term, but both his immune system and his blood were transformed by the transplant of his sister’s cord blood stem cells. Soon after this first documented cord blood stem cell transplant, the first public umbilical cord blood bank was established in 1991 in New York (McGuckin & Forraz, 2008).
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.
