In addition to the stem cells, researchers are discovering specific uses for the other types of cells in the treatment of certain conditions. Cord blood Treg cells hold potential for preventing graft-versus-host disease in stem cell transplantations and ameliorating the effects of autoimmune diseases such as diabetes, rheumatoid arthritis and multiple sclerosis. Cord blood natural killer cells also hold future potential. These cells have been programmed to target specific cancers and tumors in clinical trials. This could make them exceptionally strong candidates for chronic or treatment-resistant cases of cancer.
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.
In an allogenic transplant, another person’s stem cells are used to treat a child’s disease. This kind of transplant is more likely to be done than an autologous transplant. In an allogenic transplant, the donor can be a relative or be unrelated to the child. For an allogenic transplant to work, there has to be a good match between donor and recipient. A donor is a good match when certain things about his or her cells and the recipient’s cells are alike. If the match is not good, the recipient’s immune system may reject the donated cells. If the cells are rejected, the transplant does not work.
A “mini-transplant” (also called a non-myeloablative or reduced-intensity transplant) is a type of allogeneic transplant. This approach is being studied in clinical trials for the treatment of several types of cancer, including leukemia, lymphoma, multiple myeloma, and other cancers of the blood.
One reason BMT and PBSCT are used in cancer treatment is to make it possible for patients to receive very high doses of chemotherapy and/or radiation therapy. To understand more about why BMT and PBSCT are used, it is helpful to understand how chemotherapy and radiation therapy work.
Stem Cell Storage is not included in their price. Viacord and Cord Blood Registry both charge for annual storage. This means that when you pay for your initial cord blood and/or cord tissue storage you will also have to pay annually for storage.
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:
Shai was a feisty little girl whose mother used her scientific background to search for the best approach to cure her cancer. Shai narrowly escaped death many times, including a recovery that even her doctors considered a miracle, yet she died at dawn on the day that she would have begun kindergarten. Her mother went on to found this website and charity in her memory. Read more…
Your cells didn’t start out knowing how to come together to form your bones, heart or blood; they begun with more of a blank slate. These completely undifferentiated cells can be found during gestation, or the time the baby is in the womb, and are called embryonic stem cells. These early stage stem cells are master cells that have the potential to become any type of cell in the body.
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.
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.
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.
In Europe, Canada, and Australia use of cord blood is regulated as well. In the United Kingdom the NHS Cord Blood Bank was set up in 1996 to collect, process, store and supply cord blood; it is a public cord blood bank and part of the NHS.
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.
The syringe or bag should be pre-labeled with a unique number that identifies your baby. Cord blood may only be collected during the first 15 minutes following the birth and should be processed by the laboratory within 48 hours of collection.
NCI’s Cancer Information Service (CIS) can provide patients and their families with additional information about sources of financial assistance at 1–800–422–6237 (1–800–4–CANCER). NCI is part of the National Institutes of Health.
To minimize potential side effects, doctors most often use transplanted stem cells that match the patient’s own stem cells as closely as possible. People have different sets of proteins, called human leukocyte-associated (HLA) antigens, on the surface of their cells. The set of proteins, called the HLA type, is identified by a special blood test.
Cord blood (short for umbilical cord blood) is the blood that remains in the umbilical cord and placenta post-delivery. At or near term, there is a maternal–fetal transfer of cells to boost the immune systems of both the mother and baby in preparation for labor. This makes cord blood at the time of delivery a rich source of stem cells and other cells of the immune system. Cord blood banking is the process of collecting the cord blood and extracting and cryogenically freezing its stem cells and other cells of the immune system for potential future medical use.

In most cases, the success of allogeneic transplantation depends in part on how well the HLA antigens of the donor’s stem cells match those of the recipient’s stem cells. The higher the number of matching HLA antigens, the greater the chance that the patient’s body will accept the donor’s stem cells. In general, patients are less likely to develop a complication known as graft-versus-host disease (GVHD) if the stem cells of the donor and patient are closely matched.
As most parents would like to bank their babies’ cord blood to help safeguard their families, it is often the cost of cord blood banking that is the one reason why they do not. Most cord blood banks have an upfront fee for collecting, processing and cryo-preserving the cord blood that runs between $1,000 and $2,000. This upfront fee often also includes the price of the kit provided to collect and safely transport the cord blood, the medical courier service used to expedite the kit’s safe shipment, the testing of the mother’s blood for any infectious diseases, the testing of the baby’s blood for any contamination, and the cost of the first full year of storage. There is then often a yearly fee on the baby’s birthday for continued storage that runs around $100 to $200 a year.
If you feel that the procedure is too expensive for your child, check with the hospital to see if there are any programs and/or grants available that can assist with the procedure. Some companies do offer financial aid.
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”.
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.
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.
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.)
In some types of leukemia, the graft-versus-tumor (GVT) effect that occurs after allogeneic BMT and PBSCT is crucial to the effectiveness of the treatment. GVT occurs when white blood cells from the donor (the graft) identify the cancer cells that remain in the patient’s body after the chemotherapy and/or radiation therapy (the tumor) as foreign and attack them.
A limitation of cord blood is that it contains fewer HSCs than a bone marrow donation does, meaning adult patients often require two volumes of cord blood for treatments. Researchers are studying ways to expand the number of HSCs from cord blood in labs so that a single cord blood donation could supply enough cells for one or more HSC transplants.
Further advancements were made in 1978, when stem cells were discovered in cord blood and in 1988, when cord blood stem cells were first used in a transplant. Stem cells extracted from the umbilical cord blood or tissue have since been shown to be more advantageous than those extracted from other sources such as bone marrow. In many ways, this is because stem cells from the umbilical cord can be considered naïve and immature compared to stem cells from other sources. Cord stem cells haven’t been exposed to disease or environmental pollutants, and they are more accepting of foreign cells. In this case, inexperience makes them stronger.
