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.
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.’
There are some hospitals that have dedicated collections staff who can process mothers at the last minute when they arrive to deliver the baby. However, in the United States that is the exception to the rule.
The second question concerns “storing” the newborn’s cord blood for the child’s future use or a family member’s future use. The American Academy of Pediatrics has issued a policy statement saying that, “Cord blood donation should be discouraged when cord blood stored in a bank is to be directed for later personal or family use.” They state: “No accurate estimates exist of the likelihood of children to need their own stored cord blood stem cells in the future. The range of available estimates is from 1 in 1000 to more than 1 in 200000.51 The potential for children needing their own cord blood stem cells for future autologous use is controversial presently.” Read the complete statement here.
Preserving stem cells does not guarantee that the saved stem cells will be applicable for every situation. Ultimate use will be determined by a physician. Please note: Americord Registry’s activities are limited to collection of umbilical cord tissue from autologous donors. Americord Registry’s possession of a New York State license for such collection does not indicate approval or endorsement of possible future uses or future suitability of cells derived from umbilical cord tissue.
Banking cord blood is a new type of medical protection, and there are a lot of questions that parents may want to ask. The Parent’s Guide to Cord Blood organization even has questions it believes all parents should ask their cord blood banks. We have answers to these and other frequently asked cord blood questions in our FAQs. If you can’t find the answer for which you are looking, please feel free to engage one of our cord blood educators through the website’s chat interface.
After entering the bloodstream, the stem cells travel to the bone marrow, where they begin to produce new white blood cells, red blood cells, and platelets in a process known as “engraftment.” Engraftment usually occurs within about 2 to 4 weeks after transplantation. Doctors monitor it by checking blood counts on a frequent basis. Complete recovery of immune function takes much longer, however—up to several months for autologous transplant recipients and 1 to 2 years for patients receiving allogeneic or syngeneic transplants. Doctors evaluate the results of various blood tests to confirm that new blood cells are being produced and that the cancer has not returned. Bone marrow aspiration (the removal of a small sample of bone marrow through a needle for examination under a microscope) can also help doctors determine how well the new marrow is working.
The Cord Blood Registry (CBR) is unique, because it is currently the world’s largest cord blood bank, with over a half-million cord blood and cord tissue units stored to date. This is substantially more than its nearest competitor, ViaCord, which has 350,000 units stored. It was recently acquired by pharmaceutical giant, AMAG Pharmaceuticals, for $700 million in June 2015.
Because identical twins have the same genes, they have the same set of HLA antigens. As a result, the patient’s body will accept a transplant from an identical twin. However, identical twins represent a small number of all births, so syngeneic transplantation is rare.
Marketing materials by Viacord and Cord Blood Registry, the two largest companies, do not mention that cord blood stem cells cannot be used by the child for genetic diseases, although the fine print does state that cord blood may not be effective for all of the listed conditions.
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.
We’d like to extend our sincere gratitude to the thousands of obstetricians, nurses, midwives, and childbirth educators who support placenta and umbilical cord blood banking. There is no doubt that these efforts save lives.
While banking cord blood is a new experience for many parents, it is a simple one. After all, most mothers are worried about how the delivery will go and don’t want to also be worried about the details of collecting, processing and cryo-preserving their babies’s cord blood. Thankfully, the healthcare provider and the cord blood bank do most of the work. Here are the steps found in cord blood banking:
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.
Stem cells also may be retrieved from umbilical cord blood. For this to occur, the mother must contact a cord blood bank before the baby’s birth. The cord blood bank may request that she complete a questionnaire and give a small blood sample.
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.
When all the processing and testing is complete, the cord blood stem cells are frozen in cryogenic nitrogen freezers at -196° C until they are requested for patient therapy. Public banks are required to complete the entire laboratory processing and freeze the cord blood stem cells within 48 hours of collection. This is to insure the highest level of stem cell viability. The accreditation agencies allow family banks a window of 72 hours.
In the rare event of a processed sample not adhering to quality standards, CBR’s certified genetic counselors will work with potential clients to help them understand their options. Under this scenario, clients will have the option to discontinue storage and receive a refund.
Potential long-term risks include complications of the pretransplant chemotherapy and radiation therapy, such as infertility (the inability to produce children); cataracts (clouding of the lens of the eye, which causes loss of vision); secondary (new) cancers; and damage to the liver, kidneys, lungs, and/or heart.
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.
Depending on the predetermined period of storage, the initial fee can range from $900 to $2100. Annual storage fees after the initial storage fee are approximately $100. It is common for storage facilities to offer prepaid plans at a discount and payment plans to help make the initial storage a more attractive option for you and your family.
The stored blood can’t always be used, even if the person develops a disease later on, because if the disease was caused by a genetic mutation, it would also be in the stem cells. Current research says the stored blood may only be useful for 15 years.
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.
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.
The cord blood of your baby is an abundant source of stem cells that are genetically related to your baby and your family. Stem cells are dominant cells in the way they contribute to the development of all tissues, organs, and systems in the body.
