Because the body’s immune system is designed to find and get rid of what it believes to be outside contaminants, stem cells and other cells of the immune system cannot be transfused into just anyone. For stem cell transfusions of any type, the body’s immune system can mistakenly start attacking the patient’s own body. This is known as graft-versus-host disease (GvHD) and is a big problem post-transplant. GvHD can be isolated and minimal, but it can also be acute, chronic and even deadly.
Within 24 hours of giving birth, your doctor will take a small blood sample. In most cases, the blood sample is sent to the bank along with your child’s cord blood. This helps the storage facility staff when checking the blood for diseases and contamination. Some hospitals may decide to test the mother’s blood for diseases themselves.
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:
Much research is focused on trying to increase the number of HSCs that can be obtained from one cord blood sample by growing and multiplying the cells in the laboratory. This is known as “ex vivo expansion”. Several preliminary clinical trials using this technique are underway. The results so far are mixed: some results suggest that ex vivo expansion reduces the time taken for new blood cells to appear in the body after transplantation; however, adult patients still appear to need blood from two umbilical cords. More research is needed to understand whether there is a real benefit for patients, and this approach has yet to be approved for routine clinical use.
The body has two ways to create more cells. The first is usually taught in middle school science. Known as cell division, it’s where a cell replicates within its membrane before dividing into two identical cells. Cells do this as needed for regeneration, which we will touch on in a second.
Stem cells are often extracted from cord blood and bone marrow.Different cells have different life cycles, and many are constantly regenerating, but when damage occurs and the body needs to come up with a new supply of cells to heal itself, it relies on the stem cell’s ability to quickly create more cells to repair the wound. Herein lays the potential for the introduction of new stem cells to enhance or be the driving factor in the healing process.
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.
Each year, thousands of people are diagnosed with leukemia, lymphoma, or certain immune system or genetic metabolic disorder. Many of these patients need an umbilical cord blood or bone marrow transplant (also called a BMT). Because the qualities that make a suitable match for bone marrow or umbilical cord blood are inherited, a match from a sibling or other family member is often checked first. However, 70 percent of patients will not find a matching donor in their family. For these patients, a transplant of bone marrow or cord blood from an unrelated donor may be their only transplant option.
Unlike some other cord blood banks, Cryo-Cell does not charge any upfront enrollment fees. You’ll be charged only after your baby’s cord blood and cord tissue have been processed and we’ve confirmed that the collection meets our high standards for viability and the number of stem cells. If for any reason your collection falls below our standards, we will notify you promptly and let you make a decision whether to continue to cryo-preserve your baby’s stem cells. Our processing fees include the first year of storage. After the first year, you can continue to pay for the storage annually or pre-pay for storage at a significantly discounted price and for added convenience. Our annual storage fees are fixed for the life of your contract.
Cord tissue use is still in early research stages, and there is no guarantee that treatments using cord tissue will be available in the future. Cord tissue is stored whole. Additional processing prior to use will be required to extract and prepare any of the multiple cell types from cryopreserved cord tissue. Cbr Systems, Inc.’s activities for New York State residents are limited to collection of umbilical cord tissue and long-term storage of umbilical cord–derived stem cells. Cbr Systems, Inc.’s possession of a New York State license for such collection and long-term storage does not indicate approval or endorsement of possible future uses or future suitability of these cells.
While the stem cell count is smaller during a cord blood transplant, these cells multiply quickly, and researchers are studying new methods to increase cells naturally. Compared to bone marrow, cord blood cells multiply faster and don’t require an exact match type to complete a successful transplant. Some techniques medical experts are testing to increase the amount of stem cells include:

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.
For these and other reasons, the American Academy of Pediatrics (AAP) and many physicians do not recommend private cord blood banking except as “directed donations” in cases where a family member already has a current need or a very high potential risk of needing a bone marrow transplant. In all other cases, the AAP has declared the use of cord blood as “biological insurance” to be “unwise.” [Read the AAP’s news release at http://www.aap.org/advocacy/archives/julcord.htm ]
Parents sign a consent form, giving the public bank permission to add their child’s cord blood to a database. This database will match transplant patients with a suitable donor. No information about the donor, or their family, is displayed online. The website used in America is Be The Match. They maintain a database of donations and banks across the country, while also working with foreign banks. Your child’s cord blood could save someone living anywhere in the world.
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.
Cord blood banking means preserving the newborn stem cells found in the blood of the umbilical cord and the placenta. After a baby is born, and even after delayed cord clamping, there is blood remaining in the umbilical cord and placenta that holds valuable newborn stem cells. Parents have a choice between donating cord blood to a public bank for free, or paying to store it for their family in a private bank. Cord blood banking includes the whole process from collection through storage of newborn stem cells for future medical purposes.
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.)
Families have the additional option of storing a section of the umbilical cord, which is rich in unique and powerful stem cells that may help repair and heal the body in different ways than stem cells derived from cord blood.
Tracey said she felt lucky since she banked Anthony’s cord blood with a private company. And Osteopetrosis is one of 80 diseases listed by many cord blood companies in their marketing material as treatable with stem cells.
Parents often complain about cord blood banking costs. This is not an industry where costs can be cut by running a turn-key operation. Each cord blood unit must be individually tested and processed by trained technicians working in a medical laboratory.
Blood from the umbilical cord and placenta is put into a sterile bag. (The blood is put into the bag either before or after the placenta is delivered, depending upon the procedure of the cord blood bank.)
You and your baby’s personal information are always kept private by the public cord blood bank. The cord blood unit is given a number at the hospital, and this is how it is listed on the registry and at the public cord blood bank.
During the harvesting procedure, doctors use a catheter to draw out blood. The blood moves through a machine, which separates stem cells and allows these cells to be put into storage. This process takes a few hours, and may be repeated over several days in order for doctors to get enough stem cells.

As a mother-to-be, you can decide that your baby’s first act may be saving another person’s life. You can do this by choosing to donate your baby’s umbilical cord blood to the St. Louis Cord Blood Bank’s First Gift℠ Donation Program.
Once donated cord blood is listed on the Be the Match registry, doctors can access it to treat patients who need stem cell transplants. Public cord blood banks keep the names of both mothers and babies confidential to protect the privacy of families.
There is often confusion over who can use cord blood stem cells in treatment — the baby they were collected from or a sibling? The short answer is both, but it very much depends on the condition being treated. And it’s ultimately the treating physician’s decision.
