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.
Yes, if you have any sick children who could benefit from umbilical cord blood. Public banks such as Carolinas Cord Bank at Duke University and private banks such as FamilyCord in Los Angeles offer programs in which the bank will assist with cord blood processing and storage if your baby has a biological sibling with certain diseases. FamilyCord will provide free cord blood storage for one year. See a list of banks with these programs at parentsguidecordblood.org/help.php.
Cord blood banking means preserving the newborn stem cells found in the blood of the umbilical cord and the placenta. After a baby is born, and even after delayed cord clamping, there is blood remaining in the umbilical cord and placenta that holds valuable newborn stem cells. Parents have a choice between donating cord blood to a public bank for free, or paying to store it for their family in a private bank. Cord blood banking includes the whole process from collection through storage of newborn stem cells for future medical purposes.
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.”
After being treated with high-dose anticancer drugs and/or radiation, the patient receives the stem cells through an intravenous (IV) line just like a blood transfusion. This part of the transplant takes 1 to 5 hours.
The body has two ways to create more cells. The first is usually taught in middle school science. Known as cell division, it’s where a cell replicates within its membrane before dividing into two identical cells. Cells do this as needed for regeneration, which we will touch on in a second.
Luckily for expectant parents, cord blood can be easily collected at the baby’s birth via the umbilical cord with no harm to the mother or baby. This is why pregnancy is a great time to plan to collect and bank a baby’s cord blood.
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.
Tracey Dones of Hicksville, N.Y., paid to bank her son Anthony’s cord blood. But four months after he was born, Anthony was diagnosed with osteopetrosis, a rare disease that causes the body to produce excess bone, leads to blindness, and can be fatal if left untreated.
Some brochures advertising private cord blood banking show children with cerebral palsy, a neurological disorder, who were treated with their own stem cells. In the case of Cord Blood Registry, the company lists all stem cell transplants conducted at Duke University. In a list of individuals treated in their “stem cell therapy data” cerebral palsy is listed. However, transplants were part of an early research study and studies of efficacy are just now underway.
Most cells can make copies only of themselves. For example, a skin cell only can make another skin cell. Hematopoietic stem cells, however, can mature into different types of blood cells in the body. Hematopoietic stem cells also are found in blood and bone marrow in adults and children.
An HLA match helps ensure the body accepts the new cell and the transplant is successful. It also reduces the risk of graft-versus-host disease (GVHD), which is when the transplanted cells attack the recipient’s body. GVHD occurs in 30%–40% of recipients when they aren’t a perfect match but the donor is still related. If the donor and recipient are not related, it increases to a 60%–80% risk. The better the match, the more likely any GVHD symptoms will be mild, if they suffer from GVHD at all. Unfortunately, GVHD can also be deadly.
Just like other blood donations, there is no cost to the donor of cord blood. If you do not choose to store your baby’s blood, please consider donating it. Your donation could make a difference in someone else’s life.
Medical staff at the public cord blood bank will check to see if you can donate. If you have had a disease that can be given to another person through blood-forming cells, such as hepatitis B, hepatitis C, or HIV (the AIDS virus), you will likely not be able to donate. However, other medical reasons may still allow you to donate, for example, hepatitis A or diabetes only during your pregnancy (gestational diabetes). The staff at the public cord blood bank will tell you.
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.
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 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.
Blood from the umbilical cord and placenta is put into a sterile bag. (The blood is put into the bag either before or after the placenta is delivered, depending upon the procedure of the cord blood bank.)
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.
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”.
There is a high likelihood that immediate biological family members could benefit from the baby’s cord tissue stem cells, with parents having a 100% likelihood of being compatible, siblings having a 75% likelihood of being compatible, and grandparents having a 25% likelihood of being compatible.16,50 Another reason why parents today are choosing to bank their baby’s cord tissue for the future.
With allogeneic transplants, GVHD sometimes develops when white blood cells from the donor (the graft) identify cells in the patient’s body (the host) as foreign and attack them. The most commonly damaged organs are the skin, liver, and intestines. This complication can develop within a few weeks of the transplant (acute GVHD) or much later (chronic GVHD). To prevent this complication, the patient may receive medications that suppress the immune system. Additionally, the donated stem cells can be treated to remove the white blood cells that cause GVHD in a process called “T-cell depletion.” If GVHD develops, it can be very serious and is treated with steroids or other immunosuppressive agents. GVHD can be difficult to treat, but some studies suggest that patients with leukemia who develop GVHD are less likely to have the cancer come back. Clinical trials are being conducted to find ways to prevent and treat GVHD.
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.
Public cord blood banks store cord blood for allogenic transplants. They do not charge to store cord blood. The stem cells in the donated cord blood can be used by anyone who matches. Some public banks will store cord blood for directed donation if you have a family member who has a disease that could potentially be treated with stem cells.
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
The blood within your baby’s umbilical cord is called ‘cord blood’ for short. Cord blood contains the same powerful stem cells that help your baby develop organs, blood, tissue, and an immune system during pregnancy. After your baby is born, and even after delayed cord clamping, there is blood left over in the umbilical cord that can be collected and saved, or ‘banked.’
