The other way the body creates more cells is through its stem cells, and stem cells do things a little differently. They undergo what is called asymmetric division, forming not one but two daughter cells: one cell often an exact replica of itself, a new stem cell with a relatively clean slate, and another stem cell that is ready to turn into a specific type of cell. This trait is known as self-renewal and allows stem cells to proliferate, or reproduce rapidly.
All cord blood is screened and tested. Whether you use a public or private bank, you’ll still need to be tested for various infections (such as hepatitis and HIV). If tests come back positive for disease or infection, you will not be able to store your cord blood.
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.
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.
Cord blood donation doesn’t cost anything for parents. Public cord blood banks pay for everything which includes the collection, testing, and storing of umbilical cord blood. This means that cord blood donation is not possible in every hospital.
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.
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.
Banked cord blood is most abundant in white blood cells and stem cells. While a lot of attention is paid to the stem cells, there are approximately 10 times more total nucleated cells (TNCs) than stem cells in any cord blood collection. TNCs are basically white blood cells, or leukocytes; they are the cells of the immune system that protect the body. Despite stem cells comprising one-tenth of most collections, cord blood is still considered a rich source of hematopoietic (he-mah-toe-po-ee-tic) stem cells (HSCs). HSCs are often designated by the marker CD34+. Hematopoietic stem cells can become two categories of cells: myeloid and lymphoid cells. Myeloid cells go on to form your red blood cells, platelets, and other cells of the blood. Lymphoid cells go on to become the B cells and T cells and are the basis for the immune system. Cord blood also contains mesenchymal (meh-sen-ki-mal) stem cells (MSCs), but they are much more abundant in cord tissue, which we will discuss in a minute.
Along with cord blood, Wharton’s jelly and the cord lining have been explored as sources for mesenchymal stem cells (MSC), and as of 2015 had been studied in vitro, in animal models, and in early stage clinical trials for cardiovascular diseases, as well as neurological deficits, liver diseases, immune system diseases, diabetes, lung injury, kidney injury, and leukemia.
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).
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.
The first successful cord blood transplant (CBT) was done in 1988 in a child with Fanconi anemia. Early efforts to use CBT in adults led to mortality rates of about 50%, due somewhat to the procedure being done in very sick people, but perhaps also due to slow development of immune cells from the transplant. By 2013, 30,000 CBT procedures had been performed and banks held about 600,000 units of cord blood.
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.
Not all moms can donate their cord blood. Moms who are not eligible are those who: are younger than 18 years old (in most states), have been treated for cancer or have received chemotherapy for another illness, have had malaria in the last three years, or have been treated for a blood disease such as HIV or hepatitis. It’s also not possible to donate cord blood if a mom has delivered her baby prematurely (there may not be enough blood to collect) or delivered multiples (but it’s possible to bank your cord blood of multiples privately).
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.
It depends on who you ask. Although commercial cord blood banks often bill their services as “biological insurance” against future diseases, the blood doesn’t often get used. One study says the chance that a child will use their cord blood over their lifetime is between 1 in 400 and 1 in 200,000.
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.

Pro: It gives you that peace of mind that if anything did happen to your child, the doctors would have access to their blood. This could potentially be a great benefit, and you would have no idea what would have happened if it weren’t for this blood.
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.

Because of the invasive procedure required to obtain the bone marrow, scientist continued to look for a better source, which eventually lead to the discovery of similar stem cells in cord blood in 1978. Cord blood was used in its first transplant in 1988, and cord blood has since been shown to be more advantageous than other means of acquiring similar stem cells and immune system cells. This is because umbilical cord blood can be considered naïve and immature compared to other sources. Cord blood has not been exposed to disease or environmental pollutants, and it is more accepting of foreign cells. In this case, inexperience makes it stronger.
A “tandem transplant” is a type of autologous transplant. This method is being studied in clinical trials for the treatment of several types of cancer, including multiple myeloma and germ cell cancer. During a tandem transplant, a patient receives two sequential courses of high-dose chemotherapy with stem cell transplant. Typically, the two courses are given several weeks to several months apart. Researchers hope that this method can prevent the cancer from recurring (coming back) at a later time.
Cord blood in public banks is available to unrelated patients who need haematopoietic stem cell transplants. Some banks, such as the NHS bank in the UK, also collect and store umbilical cord blood from children born into families affected by or at risk of a disease for which haematopoietic stem cell transplants may be necessary – either for the child, a sibling or a family member. It is also possible to pay to store cord blood in a private bank for use by your own family only.
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.

There are so many things to think about when you have a child. One of them is the blood from your baby’s umbilical cord (which connects the baby to the mother while in the womb). It used to be thrown away at birth, but now, many parents store the blood for the future health of their child. Should you do it?
* Disclaimer: Banking cord blood does not guarantee that treatment will work and only a doctor can determine when it can be used. Cord tissue stem cells are not approved for use in treatment, but research is ongoing.
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.
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.
In terms of performance, our PrepaCyte-CB processing method has taken the lead. PrepaCyte-CB greatly improves on parents’ returns on investment because it yields the highest number of stem cells while showing the greatest reduction in red blood cells.1–4 Clinical transplant data show that cord blood processed with PrepaCyte-CB engrafts more quickly than other processing methods.7 This means patients may start feeling better more quickly, may spend less time in the hospital and are less likely to suffer from an infection. The ability to get better more quickly and a reduced chance of infection can prove vital in certain cases. Learn more about PrepaCyte®-CB here.
