Prior to freezing the cells, samples are taken for quality testing. Banks measure the number of cells that are positive for the CD34 marker, a protein that is used to estimate the number of blood-forming stem cells present. Typical cost, $150 to $200 per unit. They also measure the number of nucleated cells, another measure of stem cells, both before and after processing to determine the cell recovery rate. Typical expense, $35 per unit. A portion of the sample is submitted to check that there is no bacterial or fungal contamination. Typical expense, $75 per unit. Public banks will also check the ability of the sample to grow new cells by taking a culture called the CFU assay. Typical expense, $200 to $250 per unit.
As noted, there are different ways to process cord blood, and although the type of processing method doesn’t always enter the conversation on cord blood banking, it is a big part of the purity of any cord blood collection. Red blood cells can have a negative impact on a cord blood transfusion. In addition, there is a certain number of stem cells that need to be present in order for the cord blood to be effective in disease treatment. Each processing method has the ability to better reduce the number of RBCs and capture more stem cells. Some processing methods like AutoXpress and Sepax are automated to ensure a level of consistency across all collections. HES is preferred by some banks because it was the original processing method used by most banks and it has a proven track record. You can read more about the different cord blood processing methods here.
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.
No one knows how stem cells will be used in the future, but researchers hope that they may be used to treat many conditions, like Alzheimer’s, diabetes, heart failure, spinal cord damage, and other conditions.
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.
Umbilical cord blood is useful for research. For example, researchers are investigating ways to grow and multiply haematopoietic (blood) stem cells from cord blood so that they can be used in more types of treatments and for adult patients as well as children. Cord blood can also be donated altruistically for clinical use. Since 1989, umbilical cord blood transplants have been used to treat children who suffer from leukaemia, anaemias and other blood diseases.
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.
As your baby’s birth approaches, think about making a cord blood donation. You have the power to Give Life to patients like Jessica. Because two babies’ families gave life through cord blood donation, she can watch her own children grow up.
Banked cord blood is most abundant in white blood cells and stem cells. While a lot of attention is paid to the stem cells, there are approximately 10 times more total nucleated cells (TNCs) than stem cells in any cord blood collection. TNCs are basically white blood cells, or leukocytes; they are the cells of the immune system that protect the body. Despite stem cells comprising one-tenth of most collections, cord blood is still considered a rich source of hematopoietic (he-mah-toe-po-ee-tic) stem cells (HSCs). HSCs are often designated by the marker CD34+. Hematopoietic stem cells can become two categories of cells: myeloid and lymphoid cells. Myeloid cells go on to form your red blood cells, platelets, and other cells of the blood. Lymphoid cells go on to become the B cells and T cells and are the basis for the immune system. Cord blood also contains mesenchymal (meh-sen-ki-mal) stem cells (MSCs), but they are much more abundant in cord tissue, which we will discuss in a minute.
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.
Today, many conditions may be treatable with cord blood as part of a stem cell transplant, including various cancers and blood, immune, and metabolic disorders. Preserving these cells now may provide your family potential treatment options in the future.
The American Academy of Pediatrics supports efforts to provide information about the potential benefits and limitations of cord blood banking and transplantation so that parents can make an informed decision. In addition, the American College of Obstetricians and Gynecologists recommends that if a patient requests information on umbilical cord blood banking, balanced information should be given. Cord blood education is also supported by legislators at the federal and state levels. In 2005, the National Academy of Sciences published an Institute of Medicine (IoM) report titled “Establishing a National Cord Blood Stem Cell Bank Program”.
Your baby’s newborn stem cells are transported to our banking facilities by our medical courier partner, and you can receive tracking updates. Each sample is processed and stored with great care at our laboratory in Tucson, Arizona. CBR’s Quality Standard means we test every cord blood sample for specific quality metrics.
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.
Cord blood can’t be used to treat everything. If your child is born with a genetic condition such as muscular dystrophy or spina bifida, then the stem cells would have that condition, says Dr. Kurtzberg. But if the cord blood donor is healthy and there is a sibling or another immediate family member who has a genetic condition, the cord blood could be a good match for them.
Umbilical cord blood can save lives. Cord blood is rich in stem cells that can morph into all sorts of blood cells, which can be used to treat diseases that harm the blood and immune system, such as leukemia and certain cancers, sickle-cell anemia, and some metabolic disorders. There are a few ways for transplant patients to get blood cells (umbilical and placenta, bone marrow, peripheral/circulation), but cord blood is easier to match with patients, and because it is gathered during birth from the umbilical cord, it’s a painless procedure.
After a baby is born, cord blood is left in the umbilical cord and placenta. It is relatively easy to collect, with no risk to the mother or baby. It contains haematopoietic (blood) stem cells: rare cells normally found in the bone marrow.
Private (commercial) cord banks will store the donated blood for use by the donor and family members only. They can be expensive. These banks charge a fee for processing and an annual fee for storage.
It’s possible that storing your child’s cord blood cells now may be useful one day in combating these diseases. For now, these treatments are only theoretical. It’s also not clear if stem cells from cord blood — as opposed to stem cells from other sources — will be useful in these potential treatments.

As cord blood is inter-related to cord blood banking, it is often a catch-all term used for the various cells that are stored. It may be surprising for some parents to learn that stored cord blood contains little of what people think of as “blood,” as the red blood cells (RBCs) can actually be detrimental to a cord blood treatment. (As we’ll discuss later, one of the chief goals of cord blood processing is to greatly reduce the volume of red blood cells in any cord blood collection.)
If siblings are a genetic match, a cord blood transplant is a simple procedure that is FDA approved to treat over 80 diseases. However, there are a few considerations you should make before deciding to only bank one of your children’s blood:
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.
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.
Another type of cell that can also be collected from umbilical cord blood are mesenchymal stromal cells. These cells can grown into bone, cartilage and other types of tissues and are being used in many research studies to see if patients could benefit from these cells too.

Life Line Stem Cell asks mothers arriving for delivery to donate all perinatal tissue: cord blood, cord tissue, and the placenta. Cord blood donations that are eligible for transplant are sent to a public cord blood bank; the tissue collections go towards research programs.
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.
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
Chloe Savannah Metz’ mother donated her baby girl’s cord blood to the NCBP in December 2000. “Many thanks to the New York Blood Center for giving us the opportunity to donate our cord — we hope to give someone a second chance!” – Christine Metz
There is often confusion over who can use cord blood stem cells in treatment — the baby they were collected from or a sibling? The short answer is both, but it very much depends on the condition being treated. And it’s ultimately the treating physician’s decision.
Blood in the umbilical cord and placenta is rich with blood-forming stem cells that can help save the lives of patients with diseases and disorders such as leukemia, lymphoma and aplastic anemia. With your consent, Canadian Blood Services can collect cord blood when you deliver your baby for Canadian Blood Services’ Cord Blood Bank—to be used by anyone who needs stem cell treatment.
Only 25-50% of donations to public cord blood banks end up being stored.4 Typically, public cord blood banks only store donations that meet the size threshold for transplant use. That means most public cord blood banks will only keep cord blood collections that are at least 3 ounces.2
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.
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.
The Doneses were shocked, however, when doctors told them that Anthony’s cord blood couldn’t be used because the cells contained the same genetic defect that caused his condition. “The materials provided by the bank said this was Anthony’s life insurance and could save him if he needed it. They never mentioned that the cells could be diseased. We felt duped,” Tracey says. The Long Island, New York, couple has since filed a lawsuit against the bank alleging false advertising and consumer fraud.
Cord blood holds promise for future medical procedures. Scientists are still studying more ways to treat more diseases with cord blood. At Duke University, for example, researchers are using patients’ own cord blood in trials for cerebral palsy and Hypoxic ischemic encephalopathy (a condition in which the brain does not receive enough oxygen). Trials are also under way for the treatment of autism at the Sutter Neuroscience Institute in Sacramento, California.
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 is a confusing topic. Many parents get bombarded with information when searching to see if cord blood banking is right for them. There is information that private cord blood banking companies, like Viacord and Cord Blood Registry, will not tell you, until now.
