Your cells didn’t start out knowing how to come together to form your bones, heart or blood; they begun with more of a blank slate. These completely undifferentiated cells can be found during gestation, or the time the baby is in the womb, and are called embryonic stem cells. These early stage stem cells are master cells that have the potential to become any type of cell in the body.
Scientists first found ways to use stem cells in bone marrow, and following this discovery, the first stem cell transplant was performed in 1956 via bone marrow between identical twins. It resulted in the complete remission of the one twin’s leukemia.
A major limitation of cord blood transplantation is that the blood obtained from a single umbilical cord does not contain as many haematopoeitic stem cells as a bone marrow donation. Scientists believe this is the main reason that treating adult patients with cord blood is so difficult: adults are larger and need more HSCs than children. A transplant containing too few HSCs may fail or could lead to slow formation of new blood in the body in the early days after transplantation. This serious complication has been partially overcome by transplanting blood from two umbilical cords into larger children and adults. Results of clinical trials into double cord blood transplants (in place of bone marrow transplants) have shown the technique to be very successful. Some researchers have also tried to increase the total number of HSCs obtained from each umbilical cord by collecting additional blood from the placenta.
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.
The University of Texas Health Science Center at Houston is conducting a pioneering FDA-regulated phase I/II clinical trial to compare the safety and effectiveness of two forms of stem cell therapy in children diagnosed with cerebral palsy. The randomized, double-blinded, placebo-controlled study aims to compare the safety and efficacy of an intravenous infusion of autologous cord blood stem cells to bone marrow stem cells.
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 parents who make the decision to store their baby’s cord blood and cord tissue are thinking ahead, wanting to do right from the start (even before the start), and taking steps to do whatever they can to protect their baby down the road. Today, many conscientious parents are also considering delayed cord clamping (DCC), a practice in which the umbilical cord is not clamped immediately but rather after it continues to pulse for an average of 30 seconds to 180 seconds. Many parents don’t realize that they can delay the clamping of the cord and still bank their baby’s cord blood. As noted early, our premium processing method, PrepaCyte-CB, is able to capture more immune system cells and reduce the greatest number of red blood cell contaminants. This makes it go hand in hand with delayed cord clamping because it is not as affected by volume, effectively making up for the smaller quantity with a superior quality. You can read more about delayed cord clamping vs. cord blood banking here.
Women thinking about donating their child’s cord blood to a public bank must pass certain eligibility requirements. While these vary from bank to bank, the following list shows general health guidelines for mothers wanting to donate.
Blood from the umbilical cord and placenta is put into a sterile bag. (The blood is put into the bag either before or after the placenta is delivered, depending upon the procedure of the cord blood bank.)
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.

The stem cells from your baby’s cord blood may also be effective in treating certain diseases or conditions of a parent or sibling. Cord blood stem cells have similar ability to treat disease as bone marrow but with significantly less rejection.
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.
If a mother meets eligibility requirements, and her baby’s cord blood is determined to be suitable for transplant, it’s stored in a public cord blood bank, and the cord blood unit is listed on the Be the Match registry. (Most blood found not suitable for transplant is used for further research.)
* Annual storage fees will be charged automatically to the credit/debit card on file, on or around your baby’s birthday, unless you’ve chosen a prepay option and are subject to change until they are paid.
While most people have a small amount of stem cells in their bloodstream, donors produce more stem cells after taking growth factor hormones. Doctors give these medications a few days before stem cell harvesting, which makes the bone marrow push more cells into the bloodstream.
ES cells are pluripotent, and similar to iPS cells, but come from an embryo. However, this kills the fertilized baby inside the embryo. This type of cell also has a high chance for graft-versus-host disease, when transplanted cells attack the patient’s body.
Most of the diseases on the proven treatment list are inherited genetic diseases. Typically, these treatments require a donor transplant, as from a sibling. In fact, research shows that treatments using cord blood from a family member are about twice as successful as treatments using cord blood from a non-relative.9a, 17 To date, over 400 ViaCord families have used their cord blood 56% were for transplant.1
STEM CELLS are found in cord blood, cord tissue, and placenta tissue. These cells are highly valuable to your baby, the mother, and possibly other family members. When you save these stem cells with Americord®, you ensure that they are securely stored for you and your family’s future needs. Learn more >
Banking of stem cells from cord blood began in 1994 with the foundation of the New York Blood Centre Cord Blood Bank. The field of umbilical cord blood storage has matured considerably over the last two decades. We continue to learn more about the long-term effects of cryo-preservation on the cells, which has resulted in increased storage times.
Cord blood is also being studied as a substitute for normal blood transfusions in the developing world. More research is necessary prior to the generalized utilization of cord blood transfusion.
As the research into umbilical cord blood and it’s therapeutic use for blood diseases has grown, so has the question as to whether people should privately store the cord blood of their offspring for future use. A recent paper on this issue by Mahendra Rao and colleagues advocates the practice of cord blood banking (for treatment of blood diseases) but in the context of public cord blood banks rather than a private cord blood banks. Any adult needing treated would need at least two cord blood samples that are immune compatible. So one sample will not be sufficient. A child might only need one cord blood sample but in the case of childhood leukaemia there is a risk that pre-leukemic cells are present in cord blood sample – and so the child could not use their own cells for therapy.

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.

Remaining in the umbilical cord and placenta is approx. 40–120 milliliters of cord blood. The healthcare provider will extract the cord blood from the umbilical cord at no risk or harm to the baby or mother.
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.
Hematopoietic stem cells can be used to treat more than 70 types of diseases, including diseases of the immune system, genetic disorders, neurologic disorders, and some forms of cancer, including leukemia and lymphoma. For some of these diseases, stem cells are the primary treatment. For others, treatment with stem cells may be used when other treatments have not worked or in experimental research programs.
