When you consider that public banks can only expect to ship 1-2% of their inventory for transplant, you can quickly understand why most public banks are struggling to make ends meet. That struggle means that fewer collection programs are staffed, and there are fewer opportunities for parents to donate to the public good. We said earlier that public banks only keep cord blood donations over a minimum of 900 million cells, but today most public banks have raised that threshold to 1.5 billion cells. The reason is that the largest units are the ones most likely to be used for transplants that bring income to the bank. Family cord blood banks do not need to impose volume thresholds because they have a profit margin on every unit banked.
Initially, cord blood stem cell transplantation using allogeneic umbilical cord blood was performed in relatively small children, because the cell dose per weight of recipient was shown to be important.19,20 However, older children, adolescents, and adults have benefited from unrelated allogeneic umbilical cord blood transplantation.34,55–61 Because of the relationship between cell dose per recipient weight and transplant outcome, the number of cord blood cells needed for marrow reconstitution in older children or young adults is much larger than that needed when cord blood is used for transplantation in small children. Cord blood transplants using multiple cryopreserved units from separate donors have been performed successfully in adults, and the approach is currently under investigation as a strategy to increase the dose of cells for transplantation in a single recipient.62 Cord blood is collected in observance of good obstetric and pediatric practice.45

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.

The main purpose of a cord blood company is to store umbilical cord blood for families in case they need to access it for future use. Cord blood from a baby is stored because it has the potential to help treat blood or immune system diseases. There are both private and public cord blood companies, sometimes referred to as cord blood banks.
That fetal blood holds all sorts of interesting — and potentially therapeutic — cells and molecules. This realization has, in some cases, changed the way the umbilical cord and placenta are handled during birth. Instead of tossing it aside, some doctors, scientists and parents are choosing to bank this fetal blood — harvesting it from the baby’s umbilical cord and placenta, freezing it and storing it away for later.
According to the statement, “Families may be vulnerable to emotional marketing at the time of birth of a child and may look to their physicians for advice. No accurate estimates exist of the likelihood of children to need their own stored cells. The range of available estimates is from 1 in 1,000 to 1 in 200,000.” For this and other reasons, it is difficult to recommend that parents store their children’s cord blood for future use. The AAP policy states:
Using their banked cord blood stem cells, ViaCord families participate in ongoing IND approved research including autism, cerebral palsy, & brain injury. Over 150 families have participated in ongoing research.
Harvesting and banking cord blood is a fairly simple procedure that can be performed during vaginal or cesarian deliveries without interrupting the birth process. The doctor or nurse will collect the cord blood after the umbilical cord has been clamped. The collection of cord blood is not painful, intrusive or risky to the mother or baby.
Most stored cord blood is discarded. At public cord blood banks, a unit of stored cord blood has a greater chance of being used to help a sick child or used toward stem cell research. Private cord blood banks, on the other hand, eventually throw away blood that a family no longer wants to store or use.
Cord blood transplants aren’t entirely new — they’ve been in use for about 20 years. In fact, the outcome of transplants has improved in the last 10 years, says Joanne Kurtzberg, M.D., director of the pediatric bone marrow and stem cell transplant program at Duke University.
Private cord blood banks store cord blood for you in case your child or someone in your immediate family needs it in the future. These private collections are owned by you and you decide how your baby’s cord blood is used. There are processing and storage fees associated with private cord blood banks.

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.
Your child may never need it. Stem cell-rich cord blood can be used to treat a range of diseases, but Frances Verter, Ph.D., founder and director of Parent’s Guide to Cord Blood Foundation, estimates that there’s only a 1 in 217 chance that your child will ever need a stem cell transplant with cord blood (or bone marrow). This is particularly true if the child doesn’t have a family history of diseases such as leukemia, lymphoma, or sickle cell anemia. Although the American Academy of Pediatrics (AAP) states cord blood has been used to treat certain diseases successfully, there isn’t strong evidence to support cord blood banking. If a family does choose to bank cord blood, the AAP recommends public cord blood banking (instead of private) to cut down on expenditures.
A well-established history. Public banks are affiliated with nonprofit research institutions or hospitals, so they have a better chance of being managed more soundly. For families without a history of diseases treated by cord blood, such as leukemia and sickle cell anemia, the American Academy of Pediatrics (AAP) recommends that cord blood be donated to public banks. Although the AAP states cord blood has been used to treat certain diseases successfully, there isn’t strong evidence to support cord blood banking. If a family does choose to bank cord blood, the AAP recommends public cord blood banking (instead of private) to cut down on expenditures. Private cord blood banks are affiliated with business corporations, so, like any business, they may go under, says William T. Shearer, M.D., Ph.D., professor of Pediatrics and Immunology at Baylor College of Medicine in Houston.
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.
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.
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.

As with all important decisions you make, the more educated you are, the better. After all, you only get one chance to bank your baby’s cord blood and you want to make sure that you choose a cord blood bank you can trust. Cord blood banking companies—especially private ones—vary widely in terms of quality, experience, and even the technology they use to collect, process, and store cord blood.
When parents donate cord blood to a public bank, they are supporting patients around the world who are searching for an unrelated Allogeneic donor. When parents save cord blood in a family bank, they are reserving the options that the baby can use its own stem cells for an Autologous treatment, or an immediate relative (sibling or parents) can use the stem cells for an Allogeneic treatment.
Accreditation agencies and registries have recognized StemCyte™ for its dedication to higher standards and patient care. StemCyte™ is the only private cord blood bank that is both FACT- and AABB-accredited.
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.
Cord blood banking means preserving the newborn stem cells found in the blood of the umbilical cord and the placenta. After a baby is born, and even after delayed cord clamping, there is blood remaining in the umbilical cord and placenta that holds valuable newborn stem cells. Parents have a choice between donating cord blood to a public bank for free, or paying to store it for their family in a private bank. Cord blood banking includes the whole process from collection through storage of newborn stem cells for future medical purposes.
In 1989, Cryo-Cell International was founded in Oldsmar, FL, making it the oldest cord blood bank in the world. By 1992, it began to store cord blood. In addition to pursuing a wide variety of accreditations (AABB, cGMP, and ISO 1345), it was the first private cord blood bank in the U.S. to be awarded FACT accreditation. In 2017, it initiated a $100,000 Engraftment Guarantee (previously $75,000), the highest quality guarantee of any U.S. cord blood bank.
