Patients with leukemia, lymphoma, or certain inherited metabolic or immune system disorders have diseased blood-forming cells. For some patients, an umbilical cord blood or bone marrow transplant (also called a BMT) may be their best treatment option.
Most public banks only work with selected hospitals in their community. They do this because they need to train the staff who will collect the cord blood, and they want the blood to be transported to their laboratory as quickly as possible. A parent who wants to donate should start by finding public banks in your country.
If everyone donated cord blood to public registries for the ‘common good’ this would increase the chances of someone benefiting from a double cord blood transplant. This far outweights the actual probability of the person who donated the sample being able to usefully use it for themself.
Though uses of cord blood beyond blood and immunological disorders is speculative, some research has been done in other areas. Any such potential beyond blood and immunological uses is limited by the fact that cord cells are hematopoietic stem cells (which can differentiate only into blood cells), and not pluripotent stem cells (such as embryonic stem cells, which can differentiate into any type of tissue). Cord blood has been studied as a treatment for diabetes. However, apart from blood disorders, the use of cord blood for other diseases is not in routine clinical use and remains a major challenge for the stem cell community.
Tracey said she felt lucky since she banked Anthony’s cord blood with a private company. And Osteopetrosis is one of 80 diseases listed by many cord blood companies in their marketing material as treatable with stem cells.
Therapies with cord blood have gotten more successful. “The outcomes of cord blood transplants have improved over the past 10 years because researchers and clinicians have learned more about dosing cord blood, picking better matches, and giving the patient better supportive care as they go through the transplant,” says Joanne Kurtzberg, M.D., director of the pediatric bone marrow and stem cell transplant program at Duke University.
Another way scientists are working with stem cells is through expansion technologies that spur replication of the cord blood stem cells. If proven effective and approved by the U.S. Food and Drug Administration, these expansion technologies will allow scientists to culture many stem cells from a small sample. This could provide doctors and researchers with enough stem cells to treat multiple family members with one cord blood collection or provide the baby with multiple treatments over time. To better prepare for the day when these expansion technologies are more easily accessible, some cord blood banks have begun to separate their cord blood collections into separate compartments, which can easily be detached from the rest of the collection and used independently.

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.
The proteins stem from three HLA genes, and you inherit one HLA from each parent, or half your HLA markers from your mother and half from your father. This gives siblings a 25 percent chance of being a perfect match, a 50 percent chance of being a partial match and another one-in-four chance of not being a match at all. Unfortunately, about seven out 10 patients who need a transplant don’t have a suitable donor in their family. They can either rely on their own stem cells, isolated before treatment or previously preserved, or try to find a match through a public donor.
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.
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.
Cord blood is used to treat children with cancerous blood disorders such as leukaemia, or genetic blood diseases like Fanconi anaemia. The cord blood is transplanted into the patient, where the HSCs can make new, healthy blood cells to replace those damaged by the patient’s disease or by a medical treatment such as chemotherapy for cancer.
Experts believe that umbilical cord blood is an important source of blood stem cells and expect that its full potential for treatment of blood disorders is yet to be revealed. Other types of stem cell such as induced pluripotent stem cells may prove to be better suited to treating non-blood-related diseases, but this question can only be answered by further research.
Umbilical cord blood is the blood left over in the placenta and in the umbilical cord after the birth of the baby. The cord blood is composed of all the elements found in whole blood. It contains red blood cells, white blood cells, plasma, platelets and is also rich in hematopoietic stem cells. There are several methods for collecting cord blood. The method most commonly used in clinical practice is the “closed technique”, which is similar to standard blood collection techniques. With this method, the technician cannulates the vein of the severed umbilical cord using a needle that is connected to a blood bag, and cord blood flows through the needle into the bag. On average, the closed technique enables collection of about 75 ml of 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

Since 1988, cord blood transplants have been used to treat over 80 diseases in hospitals around the world. Inherited blood disorders such as sickle cell disease and thalassemia can be cured by cord blood transplant. Over the past decade, clinical trials have been developing cord blood therapies for conditions that affect brain development in early childhood, such as cerebral palsy and autism.
Bone marrow is the soft, sponge-like material found inside bones. It contains immature cells known as hematopoietic or blood-forming stem cells. (Hematopoietic stem cells are different from embryonic stem cells. Embryonic stem cells can develop into every type of cell in the body.) Hematopoietic stem cells divide to form more blood-forming stem cells, or they mature into one of three types of blood cells: white blood cells, which fight infection; red blood cells, which carry oxygen; and platelets, which help the blood to clot. Most hematopoietic stem cells are found in the bone marrow, but some cells, called peripheral blood stem cells (PBSCs), are found in the bloodstream. Blood in the umbilical cord also contains hematopoietic stem cells. Cells from any of these sources can be used in transplants.
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.
Tom Moore, CEO of Cord Blood Registry, the largest private cord blood banking firm, told ABC News conceded that there was no proof that the transplants worked, but added that there is strong anecdotal evidence.
After your baby is born the umbilical cord will be clamped and cut. Using ViaCord’s collection kit, your medical professional will insert a needle into the umbilical cord and let the remaining blood drain into our collection bag.
In this way, cord blood offers a useful alternative to bone marrow transplants for some patients. It is easier to collect than bone marrow and can be stored frozen until it is needed. It also seems to be less likely than bone marrow to cause immune rejection or complications such as Graft versus Host Disease. This means that cord blood does not need to be as perfectly matched to the patient as bone marrow (though some matching is still necessary).

CBR collection kits have been designed to shield the samples from extreme temperatures (shielding for more than 1 hour at extreme hot and cold). Samples remain at room temperature and are shipped directly to the CBR lab for processing.
You’ve just visited the doctor and the good news is that you’re going to have a baby and everything looks good. Thirty years ago, your doctor may have given you a baby book and information about products that sponsors want you to buy for your new addition. Today, along with pretty much the same materials, you’ll be asked to consider saving the blood of your newborn that’s left over in the umbilical cord and placenta after the delivery. Another big decision, and possibly a costly one.
Some controversial studies suggest that cord blood can help treat diseases other than blood diseases, but often these results cannot be reproduced. Researchers are actively investigating if cord blood might be used to treat various other diseases.
Brigham and Women’s Hospital and Dana-Farber Cancer Institute jointly oversee the Cord Blood Donation Program to provide hope to all patients in need of a life-saving stem cell transplant. For more information about the stem cell transplant program please visit The Stem Cell/Bone Marrow Transplant Program at Dana-Farber/Brigham and Women’s Cancer Center (DF/BWCC) web site.
Dennis Michael Todd, PhD, joined Community Blood Services as its President and CEO in 2000. Community Blood Services operates the NJ Cord Blood Bank and The HLA Registry bone marrow donor center, both of which are affiliated with the National Marrow Donor Program (NMDP). In 2012, the blood center expects to distribute over 85,000 units of red cells and 20,000 platelets to hospitals and medical centers throughout northern NJ and Orange County, NY. Dr. Todd is presently a member of the NMDP Executive Committee and Chairman of the Finance Committee. He is a member of the International Society for Cellular Therapy (ISCT), the International Society for Stem Cell Research (ISSCR), the AABB, the American Association of Bioanalysts, and the New Jersey Society of Blood Bank Professionals.
To prevent graft-versus-host disease and help ensure engraftment, the stem cells being transfused need to match the cells of the patient completely or to a certain degree (depending on what is being treated). Cord blood taken from a baby’s umbilical cord is always a perfect match for the baby. In addition, immediate family members are more likely to also be a match for the banked cord blood. Siblings have a 25 percent chance of being a perfect match and a 50 percent chance of being a partial match. Parents, who each provide half the markers used in matching, have a 100% chance of being a partial match. Even aunts, uncles, grandparents and other extended family members have a higher probability of being a match and could possibly benefit from the banked cord blood. Read more reasons why you should bank cord blood.
The process used to collect cord blood is simple and painless. After the baby is born, the umbilical cord is cut and clamped. Blood is drawn from the cord with a needle that has a bag attached. The process takes about 10 minutes.

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
If you want the blood stored, after the birth, the doctor clamps the umbilical cord in two places, about 10 inches apart, and cuts the cord, separating mother from baby. Then she inserts a needle and collects at least 40 milliliters of blood from the cord. The blood is sealed in a bag and sent to a lab or cord blood bank for testing and storage. The process only takes a few minutes and is painless for mother and baby.
Private cord blood banking costs $2,000 to $3,000 for the initial fee, and around another $100 per year for storage. While that may seem like a hefty price tag, many expectant parents may see it as an investment in their child’s long-term health.
