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.
An additional cost that is borne only by public banks is the “HLA typing” that is used to match donors and patients for transplants. This is an expensive test, running about $75 to $125 per unit. Family banks always defer this test until it is known whether a family member might use the cord blood for therapy.
Cord blood stem cells are classified as adult (or non-embryonic) stem cells. Embryonic stem cells (ESC) are believed to be more advantageous for the treatment of disease or injury due to their pluripotent nature; that is, they have the ability to differentiate into all the cells present in the human body derived from the three germ layers (endoderm, mesoderm, and ectoderm). Adult stem cells are multipotent, implying that they can only differentiate into a limited number of cells typically within the same “family” (e.g., hematopoietic stem cells give rise to red blood cells, white blood cells, and platelets).
Public cord blood banking supports the health of the community. Public banks collect qualifying cord blood donations from healthy pregnancies and save them in case one of them will be the match to save the life of a patient who needs a stem cell transplant. In the United States our registry of donors is called Be The Match. Patients who have a rare genetic type are more likely to receive cord blood transplants. In order for parents to donate cord blood to a public bank, their baby must be born at a hospital that accepts donations. Public cord blood banking is highly recommended by both the American Academy of Pediatrics (AAP) and American Medical Association (AMA).
The main reason for this requirement is to give the cord blood bank enough time to complete the enrollment process. For the safety of any person who might receive the cord blood donation, the mother must pass a health history screening. And for ethical reasons, the mother must give informed consent.
“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.
When the medical courier delivers the cord blood collection kit to the cord blood bank, it is quickly processed to ensure the continued viability of the stem cells and immune system cells found in the cord blood. Firstly, a sample of the cord blood is tested for microbiological contamination, and the mother’s blood is tested for infectious diseases. As these tests are being conducted, the cord blood is processed to reduce the number of red blood cells and its total volume and isolate the stem cells and immune cells.
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.
Private companies offer to store cord blood for anyone who wants it done, whether or not there is any medical reason known to do so at the time. The fee for private storage varies, but averages about $1,500 up front and $100 per year for storage. When there is no one in the family who needs a transplant, private storage of a newborn’s cord blood is done for a purely speculative purpose that some companies have termed “biological insurance.”
The Stem Cell Therapeutic and Research Act was passed in 2005, which supports building a public reserve of 150,000 cord blood units from ethnically diverse donors in order to treat more than 90% of patients in need of HSC transplants. Donors from ethnic minority patients are particularly in need due to the greater variation of HLA-types in non-Caucasian ethnicities. Thirty-five percent of cord blood units go to patients of diverse ethnic and racial backgrounds.

Current research aims to answer these questions in order to establish whether safe and effective treatments for non-blood diseases could be developed in the future using cord blood. An early clinical trial investigating cord blood treatment of childhood type 1 diabetes was unsuccessful. Other very early stage clinical trials are now exploring the use of cord blood transplants to treat children with brain disorders such as cerebral palsy or traumatic brain injury. However, such trials have not yet shown any positive effects and most scientists believe much more laboratory research is needed to understand how cord blood cells behave and whether they may be useful in these kinds of treatments
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.
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.
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.
Fortunately, those odds should improve soon. In 2005, Congress passed the Stem Cell Therapeutic and Research Act, which provides $79 million in federal funding to create a centralized cord-blood registry much like the one that exists for bone marrow. The goal is to expand the existing inventory of 45,000 donated cord-blood units to 150,000.
In the procurement of embryonic stem cells for research, the embryo from which the cells are harvested is destroyed. For those who believe that human life begins at conception this research is obviously unethical. In contrast, adult stem cells can be isolated from tissue from a consenting patient. While cord blood stem cells are classified as adult stem cells, they appear to have greater potency (ability to differentiate into other cell types) than other adult stem cells, making them a potentially valuable option for use in a variety of treatments and therapies. Cord blood stem cells offer some of the advantages of ESCs without any of the ethical drawbacks. Research into the use of cord blood stem cells for the treatment of disease and disability is a promising and ethical avenue of stem cell research.
If you’re thinking about banking your baby’s cord blood stem cells, one question you’ve probably considered is whether to choose a private or public cord blood bank. As with any major decision in your life, it pays to do your research so you can make the best choice for your family about the future of your baby’s cord blood.
Checked to make sure it has enough blood-forming cells for a transplant. (If there are too few cells, the cord blood unit may be used for research to improve the transplant process for future patients or to investigate new therapies using cord blood, or discarded.)
* 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.
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.
You certainly should, especially if you have a family history of any diseases or conditions that could be treated with cord blood stem cells. Since there is only a 25% chance of a match, you should bank the cord blood of each individual child if you have the means.

The majority of programs that accept cord blood donations require the mother to sign up in advance. In the united States, the current requirement is to sign up by the 34th week of pregnancy. This cannot be over-stressed; time and time again, mothers who want to donate are turned away because they did not inquire about donation until it was too late.
They aren’t the only ones questioning the business practices of private cord-blood banks. Both the American College of Obstetricians and Gynecologists (ACOG) and the American Academy of Pediatrics (AAP) issued statements in the late 1990s opposing the use of for-profit banks — and criticizing their marketing tactics. Instead, they recommended that parents donate cord blood to public banks, which make it available for free to anyone who needs it. Globally, other organizations have done the same. Italy and France have banned private cord-blood banking altogether.
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 baby’s cord blood could be a valuable resource for another family. From foundations to non-profit blood banks and medical facilities, there are numerous locations that will collect, process, and use the stem cells from your baby’s cord blood to treat other people.
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.
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?
Cord blood cannot be used if the donor (baby) contains the same genetic illness as the recipient. Most cord blood banks glaze over this, but it is important to understand that the odds of using cord blood for the same child are much lower than the odds of using them for a sibling.
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.
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.

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.

Meet Dylan. Diagnosed with leukemia at just 8 weeks old, he received a life-saving cord blood transplant at 6 months old. Today, Dylan is growing up strong, going to school, travelling with his family and just having fun being a kid!
The mother signs an informed consent which gives a “public” cord blood bank permission to collect the cord blood after birth and to list it on a database that can be searched by doctors on behalf of patients. The cord blood is listed purely by its genetic type, with no information about the identity of the donor. In the United States, Be The Match maintains a national network of public cord blood banks and registered cord blood donations. However, all the donation registries around the world cooperate with each other, so that a patient who one day benefits from your child’s cord blood may come from anywhere. It is truly a gift to the benefit of humankind.
The European Group on Ethics in Science and New Technologies (EGE) has also adopted a position on the ethical aspects of umbilical cord blood banking. The EGE is of the opinion that “support for public cord blood banks for allogeneic transplantations should be increased and long term functioning should be assured.” They further stated that “the 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.”
