While the transplantation of cord blood has its advantages, its main disadvantage is the limited amount of blood contained within a single umbilical cord. Because of this, cord blood is most often transplanted in children. Physicians are currently trying to determine ways that cord blood can be used in larger patients, such as transferring two cord blood units or increasing the number of cells in vitro before transplanting to the patient. It also takes longer for cord blood cells to engraft. This lengthier period means that the patient is at a higher risk for infection until the transplanted cells engraft. Patients also cannot get additional donations from the same donor if the cells do not engraft or if the patient relapses. If this is the case, an additional cord blood unit or an adult donor may be used. While cord blood is screened for a variety of common genetic diseases, rare genetic diseases that manifest after birth may be passed on. The National Cord Blood Program estimates that the risk of transmitting a rare genetic disorder is approximately 1 in 10,000.
You and your baby’s personal information are always kept private by the public cord blood bank. The cord blood unit is given a number at the hospital, and this is how it is listed on the registry and at the public cord blood bank.
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

“One of the wonderful things about cord blood is that unlike bone marrow, you don’t always need a perfect match in order for it to work,” says Dr. Kurtzberg, who performed the first unrelated cord-blood transplant in the U.S. And it was a public donation that ultimately saved Anthony Dones. Within a week of starting a search, the National Cord Blood Program, a public bank operated by the New York Blood Center, found a “close enough” match. Had the now-3-year-old been forced to rely on a bone-marrow match, he might still be waiting.
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.
Cord blood collection is a completely painless procedure that does not interfere with the birth or with mother-and-child bonding following the delivery. There is no risk to either the mother or baby. Cord blood collection rarely requires Blood Center staff to be present during the baby’s delivery. There is no cost to you for donating.
There was a time before the 1990s when the umbilical cord and its blood were considered medical waste. Today, parents bank or store their baby’s umbilical cord blood because the stem cells it contains are currently utilized or show promise in the treatment of life-threatening and debilitating diseases.
While many diseases can be treated with a cord blood transplant, most require stem cells from another donor (allogeneic). Cord blood cells taken from the patient (autologous) typically contain the same defect or precancerous cells that caused the patient to need the transplant in the first place. Most medical professionals believe the chance that cord blood banking will be utilized by the patient or a close relative is relatively low. Estimates range from 1 out of 1,000 to 1 out of 200,000. From these estimates, privately stored cord blood is not likely to be utilized by the average family. The American Academy of Pediatrics has discouraged cord blood banking for self-use, since most diseases requiring stem cell transplants are already present in the cord blood stem cells. Additionally, a recent study published in Pediatrics indicates that few transplants have been performed using privately stored cord blood. From the responses of 93 transplant physicians, in only 50 cases was privately banked blood used. In 9 of these cases the cord blood was transplanted back into the donor patient (autologous transplant). One of the main selling points of private cord blood banks is the possibility of a future autologous transplant.
If you or your spouse or partner has a family history of a disease that is treatable with stem cells, or if a family member is currently in need of a stem cell transplant, private cord blood banking could be the right choice for you.

In March 2004, the European Union Group on Ethics (EGE) has issued Opinion No.19 titled Ethical Aspects of Umbilical Cord Blood Banking. The EGE concluded that “[t]he legitimacy of commercial cord blood banks for autologous use should be questioned as they sell a service, which has presently, no real use regarding therapeutic options. Thus they promise more than they can deliver. The activities of such banks raise serious ethical criticisms.”
Several research teams have reported studies in animals suggesting that cord blood can repair tissues other than blood, in diseases ranging from heart attacks to strokes. These findings are controversial: scientists often cannot reproduce such results and it is not clear HOW cord blood may be having such effects. When beneficial effects are observed they may be very slight and not significant enough to be useful for developing treatments. If there are positive effects, they might be explained not by cord blood cells making nerve or heart cells, but by the cells in the cord blood releasing substances that help the body repair damage.
I am currently 38 years old and I would like to have my blood and it’s stem cells harvested via peripheral blood draw to be stored in definitely. Do you offer this service? If so, how can I arrange for my family?
The Leading the Way LifeSaving Ambassadors Club is a recognition program honoring sponsor groups for outstanding performance in reaching or exceeding blood drive collections goals. CBC presents a Leading the Way plaque to winning sponsors on an annual basis. The award is based on three levels of achievement:
The longest study to date, published in 2011 by Broxmeyer at al found that stem cells cyro-preserved for 22.5 years engrafted as expected. There was no significant loss of stem cell recovery or proliferation.
If cord blood can be used for parents is the very common question that many adults have. And of course, the answer is Yes”. Actually, it’s very common reason for the parents to save and store their baby’s umbilical cord blood. And it’s not…
Donating your baby’s umbilical cord blood may offer a precious resource to a patient in need of a life-saving stem cell transplant. Umbilical cord blood is rich in blood-forming stem cells, which can renew themselves and grow into mature blood cells. After your baby is born, these cord blood cells can be collected, preserved and later used as a source of stem cells for transplantation for patients with leukemia, lymphoma, and other life-threatening blood diseases.
After the birth of a baby, the umbilical cord and placenta are typically discarded as medical waste, but if requested, stem cells from the cord blood inside of them can be collected for storage or donation. Stem cells can be used to treat a variety of diseases. Learn what these diseases are in our comprehensive list of diseases treatable with cord blood stem cells.
Public cord blood banks offer free cord blood banking to anyone who meets their donation requirements. They are usually supported by federal or private funding, which is why they can perform these collections at no cost to the family. The pros and cons of public cord blood banking are listed below.
Complicating matters further, each public bank has its own registry, so transplant centers must search many different databases to find a match for a patient. Currently, a Caucasian patient has an 88 percent chance of finding a cord-blood match through a public-bank registry, and minorities have a 58 percent chance. (Collection hospitals tend to be in areas with higher rates of Caucasian births, and parents from certain ethnic groups are wary of donating for religious or cultural reasons.)
ViaCord’s Lab is FDA registered, AABB accredited, CLIA certified and equipped with the same freezers used by major research institutions such as Centers for Disease Control and Prevention and the National Institutes of Health.
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.
In the public arena there has been much discussion on the benefits of for-profit private cord blood banking over public banking. Numerous for-profit companies offer new parents the option of collecting and storing cord blood for future use by the donor infant, siblings, or other family members. Parents may choose to bank cord blood if they have a family history of a particular disease or disorder, or as a means of “biological insurance” in case their child or family member develops a medical condition or becomes injured requiring a transplant.
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.
Companies throughout Europe also offer commercial (private) banking of umbilical cord blood. A baby’s cord blood is stored in case they or a family member develop a condition that could be treated by a cord blood transplant. Typically, companies charge an upfront collection fee plus an annual storage fee.
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.
In addition to the use of cord blood stem cells for transplantation, cord blood stem cells are currently being investigated for use in stem cell therapy. Cord blood stem cells are multipotent and are believed to have greater plasticity (the ability to form into different stem cell types) than adult hematopoietic stem cells found in bone marrow. HSCs are being investigated for use in autoimmune diseases such as diabetes, rheumatoid arthritis, and systemic lupus erythermatosis (SLE) in order to reprogram or reconstitute the immune system. Additionally, research is being conducted on differentiating HSCs into other tissue types such as skeletal and cardiac muscle, liver cells (hepatocytes), and neurons. HSCs are currently being used in gene therapy, due to their self-renewing properties, as a means of delivering genes to repair damaged cells. HSCs are the only cells currently being used in this manner in clinical gene therapy trials.
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?
Are public banks and family banks the same, except for who may use the cord blood and the cost to the parents? No. Public banks are subject to much higher regulatory requirements, and compliance with regulations carries costs. At a family bank you pay the bank enough to cover the cost of storing your baby’s cord blood, plus they make a profit. When you donate to a public bank, it costs you nothing, but the bank pays more on processing each blood collection than at a family bank. Let’s look at the steps that take place in the laboratory.
For example, in the UK the NHS Cord Blood Bank has been collecting and banking altruistically donated umbilical cord blood since 1996. The cord blood in public banks like this is stored indefinitely for possible transplant, and is available for any patient that needs this special tissue type. There is no charge to the donor but the blood is not stored specifically for that person or their family.

“Raising a family is expensive enough,” says Jeffrey Ecker, MD, director of obstetrical clinical research at Massachusetts General Hospital, in Boston, and a member of ACOG’s ethics committee. “There’s no reason for parents to take on this additional financial burden when there’s little chance of a child ever using his own cord blood.”
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
