While cord-blood companies herald the possible future treatments of many adult diseases with stem cells, they rarely mention a key issue. Researchers have greater hopes for the potential of embryonic stem cells, which are thought to have the ability to develop into many different types of cells. It is not known whether the stem cells in cord blood have that ability; until recently, it was thought that they (like those in bone marrow) could only regenerate blood and immune cells.
Umbilical cord blood was once discarded as waste material but is now known to be a useful source of blood stem cells. Cord blood has been used to treat children with certain blood diseases since 1989 and research on using it to treat adults is making progress. So what are the current challenges for cord blood research and how may it be used – now and in the future?
Because of the invasive procedure required to obtain the bone marrow, scientist continued to look for a better source, which eventually lead to the discovery of similar stem cells in cord blood in 1978. Cord blood was used in its first transplant in 1988, and cord blood has since been shown to be more advantageous than other means of acquiring similar stem cells and immune system cells. This is because umbilical cord blood can be considered naïve and immature compared to other sources. Cord blood has not been exposed to disease or environmental pollutants, and it is more accepting of foreign cells. In this case, inexperience makes it stronger.
The Medical Letter On Drugs and Therapeutics also recently addressed aspects of public and private cord blood banks, asking the question: “Does Private Banking Make Sense?” After citing various statistics on the actual uses of privately stored cord blood, they concluded that: “At the present time, private storage of umbilical cord blood is unlikely to be worthwhile. Parents should be encouraged to contribute, when they can, to public cord blood banks instead.” [Access The Medical Letter at www.medicalletter.org].
Complications Side Effects As the donor’s stem cells will always be a perfect match, there will be no incidence of graft versus host disease (GVHD), which can be a chronic and even fatal condition. Graft versus host disease (GVHD) is estimated to occur in 60–80 percent of transplants where the donor and recipient are not related. Perfect match! No incidence of graft versus host disease Graft versus host disease (GVHD) occurs in 60%–80% of non-related transplants.
Stem cell transplant using an individual’s own cord blood (called an autologous transplant) cannot be used for genetic disorders such as sickle cell disease and thalassemia, because the genetic mutations which cause these disorders are present in the baby’s cord blood. Other diseases that are treated with stem cell transplant, such as leukemia, may also already be present in a baby’s cord blood.
We are genetically closest to our siblings. That’s because we inherit half of our DNA from our mother and half from our father, so the genes we inherit are based on a chance combination of our parents’. Our siblings are the only other people inheriting the same DNA.
Clearly, it is advantageous to save cord blood stem cells, but it can be confusing to decide where to store them. There are currently two options: public cord blood banks and private cord blood banks. Public and private banks serve very different purposes, and it is important to know which type of bank would be more beneficial to you and your family.
Cost to Donate Client pays a one-time processing fee and annual storage fees. There is no cost for donating, but there is a cost for retreiving from a public bank. One-time processing fee and annual storage fees No cost for donating, but high cost for public bank retrival
In fact, the shocking truth is that the majority of all cord blood stored in private banks may be unusable. Approximately 75 percent of the units donated to public banks are discarded or used in research because they don’t contain enough stem cells for transplants, says Mary Halet, manager of cord-blood operations for the Center for Cord Blood at the National Marrow Donor Program, a Minneapolis-based nonprofit organization that maintains the nation’s largest public supply of cord blood. Yet private banks store every unit they collect, which means that you might pay to store blood that won’t be usable if you need it years later.

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.
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.
The cord blood of your baby is an abundant source of stem cells that are genetically related to your baby and your family. Stem cells are dominant cells in the way they contribute to the development of all tissues, organs, and systems in the body.
Currently, ViaCord has released the most cord blood units for medical transplant and has the highest cord blood transplant survival rate among companies who have disclosed complete transplant data. The one-year survival rate of patients who were treated with ViaCord cord blood units is 88%, and the long-term patient survival rate is 82%.1
After your baby is born, the umbilical cord and placenta are usually thrown away. Because you are choosing to donate, the blood left in the umbilical cord and placenta will be collected and tested. Cord blood that meets standards for transplant will be stored at the public cord blood bank until needed by a patient. (It is not saved for your family.)

Stem cell transplants from a related family member are less likely to be rejected, therefore having your baby’s stem cells available makes it less likely you would have to search for an unrelated donor who is a match
Collection hospitals for the NY Blood Center do NOT require advance registration: mothers can give a partial consent to collect the cord blood during labor, and only if the collected cord blood is suitable for transplantation will the mothers will be given additional education and asked for a final banking consent post-delivery.
The unpredictability of stem cell transportation led CBR to create a crush-resistant, temperature-protected, and electronically tracked collection kit that is designed to preserve the integrity and to help ensure the safe delivery of the blood and/or tissue. CBR’s CellAdvantage® Collection Kit contains everything the healthcare provider needs to easily and safely collect the maximum amount of a newborn’s cord blood following birth.

Some public banks offer sibling-directed donation programs where you can donate cord blood and designate it for use by your baby’s full sibling if that sibling has been diagnosed with a disease for which a cord blood transplant is considered standard treatment.
Cord blood is the blood that remains in the umbilical cord and placenta following birth. This blood is usually discarded. However, cord blood banking utilizes facilities to store and preserve a baby’s cord blood. If you are considering storing your baby’s cord blood, make sure to use a cord blood bank accredited by the American Association of Blood Banks (AABB), like Viacord.
Your free donation will be part of a program that is saving lives and supporting research to discover new uses for cord blood stem cells. Units that meet criteria for storage are made available to anyone, anywhere in the world, who needs a stem cell transplant.
If clients need to use the cord blood stem cells stored with CBR for transplantation and the cells fail to engraft, clients receive a full refund of all fees paid to CBR for cord blood services plus an additional $50,000.
