There have been several reports suggesting that cord blood may contain other types of stem cells which can produce specialised cells that do not belong to the blood, such as nerve cells. These findings are highly controversial among scientists and are not widely accepted.
Research is being conducted using cord blood cells to analyze immune response and other factors that may eventually shed light on causes and treatment of MS. However, at present there is no treatment available involving cord blood cells. Nor do we know of any sites that are looking for cord blood specifically for MS research.
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.
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.
Stem cells from cord blood can be given to more people than those from bone marrow. More matches are possible when a cord blood transplant is used than when a bone marrow transplant is used. In addition, the stem cells in cord blood are less likely to cause rejection than those in bone marrow.
CBR created the world’s only collection device designed specifically for cord blood stem cells. CBR has the highest average published cell recovery rate in the industry – 99% – resulting in the capture of 20% more of the most important cells than other common processing methods.
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 blood that remains in the umbilical cord and the placenta after birth is called “cord blood”. Umbilical cord blood, umbilical cord tissue, and the placenta are all very rich sources of newborn stem cells. The stem cells in the after birth are not embryonic. Most of the stem cells in cord blood are blood-forming or hematopoietic stem cells. Most of the stem cells in cord tissue and the placenta are mesenchymal stem cells.
Umbilical cord blood was once discarded as waste material but is now known to be a useful source of blood stem cells. Cord blood has been used to treat children with certain blood diseases since 1989 and research on using it to treat adults is making progress. So what are the current challenges for cord blood research and how may it be used – now and in the future?
Cord Blood Registry® (CBR®) is the world’s largest newborn stem cell company. Founded in 1992, CBR is entrusted by parents with storing samples from more than 600,000 children. CBR is dedicated to advancing the clinical application of cord blood and cord tissue stem cells by partnering with institutions to establish FDA-regulated clinical trials for conditions that have no cure today.
Clinical trials that include BMT and PBSCT are a treatment option for some patients. Information about ongoing clinical trials is available from NCI’s CIS at 1–800–422–6237 (1–800–4–CANCER) or on NCI’s website.
Tissue typed and listed on the registry of the C.W. Bill Young Cell Transplantation Program, also called the Be The Match Registry®. (The registry is a listing of potential marrow donors and donated cord blood units. When a patient needs a transplant, the registry is searched to find a matching marrow donor or cord blood unit.)
You certainly should, especially if you have a family history of any diseases or conditions that could be treated with cord blood stem cells. Since there is only a 25% chance of a match, you should bank the cord blood of each individual child if you have the means.
Umbilical cord blood contains haematopoietic (blood) stem cells. These cells are able to make the different types of cell in the blood – red blood cells, white blood cells and platelets. Haematopoietic stem cells, purified from bone marrow or blood, have long been used in stem cell treatments for leukaemia, blood and bone marrow disorders, cancer (when chemotherapy is used) and immune deficiencies.
Once it arrives at the storage facility, the cord blood will be processed and placed in storage. The cord blood will either be completely immersed in liquid nitrogen or it will be stored in nitrogen vapor.
If you do decide to bank your baby’s cord blood, there’s one more thing to keep in mind: It’s best not to make it a last-minute decision. You should coordinate with the bank before your baby is born so nothing is left to chance.
However, the American Academy of Pediatrics strongly encourages umbilical cord donations for general research purposes. Donors are encouraged to contact a cord blood bank by the 35th week of pregnancy.
We are genetically closest to our siblings. That’s because we inherit half of our DNA from our mother and half from our father, so the genes we inherit are based on a chance combination of our parents’. Our siblings are the only other people inheriting the same DNA.
If someone doesn’t have cord blood stored, they will have to rely on stem cells from another source. For that, we can go back to the history of cord blood, which really begins with bone marrow. Bone marrow contains similar although less effective and possibly tainted versions of the same stem cells abundant in cord blood. Scientists performed the first bone marrow stem cell transplant in 1956 between identical twins. It resulted in the complete remission of the one twin’s leukemia.
Taking time to consider helping another person when you are already busy planning for the birth of your child is greatly appreciated. A gift of cord blood may someday give someone a second chance at 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.
We offer standard and premium cord blood processing options. Our standard service has been used in thousands of successful transplants since 1988 and begins at $1600. For $350 more, our premium service uses a superior new processing method that greatly enhances parents’ return on investment. (Please visit our processing technology page to learn about our cord blood processing methods.) For an additional $950, you can also store your baby’s cord tissue, which has the potential to help heal the body in different ways than cord blood.
With the consent of the parents, blood can be collected from the umbilical cord of a newborn baby shortly after birth. This does not hurt the baby or the mother in any way, and it is blood that would otherwise be discarded as biological waste along with the placenta (another rich source of stem cells) after the birth.
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.
Private cord blood banking is recommended for families with a history of certain diseases. Specifically, these are families with diseases that harm the blood and immune system, such as leukemia and certain cancers, sickle-cell anemia, and some metabolic disorders. Why? The type of stem cells in cord blood can form all kinds of blood cells that can help treat these diseases.

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.
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.
The term “cord blood” is used for the blood remaining in the umbilical cord and the placenta after the birth of a baby. Cord Blood contains stem cells that can grow into blood and immune system cells, as well as other types of cells. Today cord blood is often used as a substitute for bone marrow in stem cell transplants. There are over 80 diseases treated this way, including cancers, blood disorders, genetic and metabolic diseases.
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.
Properly preserved cord blood is long-lasting. Cord blood is stored in a nitrogen freezer (the same technology used to freeze donated sperm), so it can last for a long time. “The scientist who first developed cord blood preservation methods in 1990 has confirmed that some of the first specimens he stored 23 plus years ago are just as potent as fresh cord blood,” says Mary Halet, Director, Central Region at Be The Match, which is operated by the National Bone Marrow Foundation.
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.
Why should you consider donating the cord blood to a public bank? Simply because, besides bringing a new life into the world, you could be saving an individual whose best chance at life is a stem cell transplant with your baby’s donated cord blood. This can only happen if you donate and if your baby is a close enough match for a patient in need. If you chose to reserve the cord blood for your family, then siblings who have the same parents have a 25% chance of being an exact match.
Chemotherapy and radiation therapy generally affect cells that divide rapidly. They are used to treat cancer because cancer cells divide more often than most healthy cells. However, because bone marrow cells also divide frequently, high-dose treatments can severely damage or destroy the patient’s bone marrow. Without healthy bone marrow, the patient is no longer able to make the blood cells needed to carry oxygen, fight infection, and prevent bleeding. BMT and PBSCT replace stem cells destroyed by treatment. The healthy, transplanted stem cells can restore the bone marrow’s ability to produce the blood cells the patient needs.
Yes, stem cells can be used on the donor following chemo and radiation to repair the bone marrow. For a full list of treatments, please visit : http://cellsforlife.com/cord-blood-basics/diseases-treated-with-cord-blood-stem-cells/
Cord blood collection is a completely painless procedure that does not interfere with the birth or with mother-and-child bonding following the delivery. There is no risk to either the mother or baby. Cord blood collection rarely requires Blood Center staff to be present during the baby’s delivery. There is no cost to you for donating.
Unlike traditional BMT or PBSCT, cells from both the donor and the patient may exist in the patient’s body for some time after a mini-transplant. Once the cells from the donor begin to engraft, they may cause the GVT effect and work to destroy the cancer cells that were not eliminated by the anticancer drugs and/or radiation. To boost the GVT effect, the patient may be given an injection of the donor’s white blood cells. This procedure is called a “donor lymphocyte infusion.”
The National Marrow Donor Program® (NMDP), a nonprofit organization, manages the world’s largest registry of more than 11 million potential donors and cord blood units. The NMDP operates Be The Match®, which helps connect patients with matching donors.
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.
