As noted, there are different ways to process cord blood, and although the type of processing method doesn’t always enter the conversation on cord blood banking, it is a big part of the purity of any cord blood collection. Red blood cells can have a negative impact on a cord blood transfusion. In addition, there is a certain number of stem cells that need to be present in order for the cord blood to be effective in disease treatment. Each processing method has the ability to better reduce the number of RBCs and capture more stem cells. Some processing methods like AutoXpress and Sepax are automated to ensure a level of consistency across all collections. HES is preferred by some banks because it was the original processing method used by most banks and it has a proven track record. You can read more about the different cord blood processing methods here.
A major limitation of cord blood transplantation is that the blood obtained from a single umbilical cord does not contain as many haematopoeitic stem cells as a bone marrow donation. Scientists believe this is the main reason that treating adult patients with cord blood is so difficult: adults are larger and need more HSCs than children. A transplant containing too few HSCs may fail or could lead to slow formation of new blood in the body in the early days after transplantation. This serious complication has been partially overcome by transplanting blood from two umbilical cords into larger children and adults. Results of clinical trials into double cord blood transplants (in place of bone marrow transplants) have shown the technique to be very successful. Some researchers have also tried to increase the total number of HSCs obtained from each umbilical cord by collecting additional blood from the placenta.
Private companies offer to store cord blood for anyone who wants it done, whether or not there is any medical reason known to do so at the time. The fee for private storage varies, but averages about $1,500 up front and $100 per year for storage. When there is no one in the family who needs a transplant, private storage of a newborn’s cord blood is done for a purely speculative purpose that some companies have termed “biological insurance.”
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.
On average, the transport time for stem cells from the hospital to CBR’s lab is 19 hours. CBR partners with Quick International, a private medical courier service with 30 years of experience in the transportation of blood and tissue for transplant and research.
Bone marrow is the soft, sponge-like material found inside bones. It contains immature cells known as hematopoietic or blood-forming stem cells. (Hematopoietic stem cells are different from embryonic stem cells. Embryonic stem cells can develop into every type of cell in the body.) Hematopoietic stem cells divide to form more blood-forming stem cells, or they mature into one of three types of blood cells: white blood cells, which fight infection; red blood cells, which carry oxygen; and platelets, which help the blood to clot. Most hematopoietic stem cells are found in the bone marrow, but some cells, called peripheral blood stem cells (PBSCs), are found in the bloodstream. Blood in the umbilical cord also contains hematopoietic stem cells. Cells from any of these sources can be used in transplants.

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.
If siblings are a genetic match, a cord blood transplant is a simple procedure that is FDA approved to treat over 80 diseases. However, there are a few considerations you should make before deciding to only bank one of your children’s blood:
There is little doubt that scientists believe umbilical cord blood stem cells hold promise for the future. Cord blood stem cells are already used to treat blood disorders such as aplastic anemia, and research is underway to determine if they can treat other more common conditions like type 1 diabetes. But many experts question whether many companies’s marketing materials confuse or even mislead parents about the usefulness of private banking.
Cord blood banks may be public or commercial. Public cord blood banks accept donations of cord blood and may provide the donated stem cells to another matched individual in their network. In contrast, commercial cord blood banks will store the cord blood for the family, in case it is needed later for the child or another family member.
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.
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.
Companies throughout Europe also offer commercial (private) banking of umbilical cord blood. A baby’s cord blood is stored in case they or a family member develop a condition that could be treated by a cord blood transplant. Typically, companies charge an upfront collection fee plus an annual storage fee.
Advances in treatment methods, including the use of PBSCT, have reduced the amount of time many patients must spend in the hospital by speeding recovery. This shorter recovery time has brought about a reduction in cost. However, because BMT and PBSCT are complicated technical procedures, they are very expensive. Many health insurance companies cover some of the costs of transplantation for certain types of cancer. Insurers may also cover a portion of the costs if special care is required when the patient returns home.
A woman can donate her baby’s umbilical cord blood to public cord blood banks at no charge. However, commercial blood banks do charge varying fees to store umbilical cord blood for the private use of the patient or his or her family.

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.

The process used to collect cord blood is simple and painless. After the baby is born, the umbilical cord is cut and clamped. Blood is drawn from the cord with a needle that has a bag attached. The process takes about 10 minutes.
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.
