Umbilical cords have traditionally been viewed as disposable biological by-product. Cord blood, however, is rich in multi-potent hematopoietic stem cells (HSCs). Recent medical advances have indicated that these stem cells found in cord blood can be used to treat the same disorders as the hematopoietic stem cells found in bone marrow and in the bloodstream but without some of the disadvantages of these types of transplants. Cord blood is currently used to treat approximately 70 diseases including leukemias, lymphomas, anemias, and Severe Combined Immunodeficiency (SCID). Six thousand patients worldwide have been treated with cord blood stem cell transplants, although the FDA considers the procedure to be experimental. These multipotent stem cells also show promise for the treatment of a variety of diseases and disorders other than those affecting the blood.
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.

Throughout pregnancy your baby’s umbilical nurtures life. It carries oxygen-rich cells and nutrients from your placenta to your baby and then allows your baby to pump deoxygenated and nutrient-depleted blood back to your placenta. This constant exchange is protected by a special type of tissue that acts like a cushion, preventing twisting and compression to ensure that the cord blood flow remains steady and constant.
The European Group on Ethics in Science and New Technologies (EGE) has also adopted a position on the ethical aspects of umbilical cord blood banking. The EGE is of the opinion that “support for public cord blood banks for allogeneic transplantations should be increased and long term functioning should be assured.” They further stated that “the legitimacy of commercial cord blood banks for autologous use should be questioned as they sell a service which has presently no real use regarding therapeutic options.”
Cord tissue is rich in another type of stem cell. Although there are no current uses, researchers are excited about the benefits cord tissue stem cells may offer in potential future users, such as regenerative medicine. By storing both, you’ll have potential access to more possibilities
Excitement about cord tissue’s potential to help conditions affecting cartilage, muscle and nerve cells continues to grow.19 Researchers are focusing on a wide range of potential treatment areas, including Parkinson’s disease, Alzheimer’s, liver fibrosis, lung cancer, and sports injuries. Since 2007 there have been 150 clinical trials using cord tissue stem cells.

Graft-versus-host disease (GVHD) is a common complication after an allogeneic transplant (from a source other than the patient) where the patient’s immune system recognizes the cells as “foreign” and attacks the newly transplanted cells. This can be a potentially life threatening complication. The risk for developing GVHD is lower with cord blood transplants than with marrow or peripheral blood transplants. Patients who do develop GVHD after a cord blood transplant typically do not develop as severe of a case of GVHD. Cord blood also is less likely to transmit certain viruses such as cytomegalovirus (CMV), which poses serious risks for transplant patients with compromised immune systems.
Are there situations where private cord blood banking might make sense? Some parents choose to bank their child’s blood if they don’t know his or her medical background — for instance, if a parent was adopted or the child was conceived with a sperm or egg donor.
Today, many conditions may be treatable with cord blood as part of a stem cell transplant, including various cancers and blood, immune, and metabolic disorders. Preserving these cells now may provide your family potential treatment options in the future.
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.
Up to 180 mL of blood can be taken from an umbilical cord for use in stem cell transplants. Due to the experimental nature of cord blood transplants, such transplants are considered on a case-by-case basis. This blood is collected from the umbilical cord, processed, and cryogenically preserved shortly after the umbilical cord is clamped. This blood can be cryogenically preserved for public or private (family) use. Public registries store cord blood donated for availability to the general public for transplantation. Private registries store cord blood on behalf of families who wish to use this blood for the donor infant, siblings, or other family members. Private cord blood banks charge a collection fee (ranging from $1,000-2,000) and an annual storage fee (approximately $150 per year).
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?
The Celebration Stem Cell Centre (CSCC), offers both public donation and private “family banking” of umbilical cord blood. All cord blood collections are processed according to the highest standards in the industry in a new, state-of-the art facility located in Gilbert, Arizona. The public cord blood donation program is funded by the private “family banking” program and private philanthropy.
Cord Blood Registry is headquartered in South San Francisco, California. CBR owns their 80,000 square foot laboratory located in Tucson, Arizona. CBR’s laboratory processes cord blood collections seven days a week, 365 days a year. The state-of-the-art facility has the capacity to store the stem cell samples of five million newborns.
After your baby is born, the umbilical cord and placenta are usually thrown away. Because you are choosing to donate, the blood left in the umbilical cord and placenta will be collected and tested. Cord blood that meets standards for transplant will be stored at the public cord blood bank until needed by a patient. (It is not saved for your family.)
Even if a sick child has a sibling donor, there’s only a 25 percent chance that cord blood will be a perfect match — and an equal chance it won’t match at all. That’s why public donations are so important. So far, many more stem-cell transplants have been done using cord blood stored in public banks. From 2000 to 2004, more than 2,200 unrelated transplants were done nationwide.
Only 25-50% of donations to public cord blood banks end up being stored.4 Typically, public cord blood banks only store donations that meet the size threshold for transplant use. That means most public cord blood banks will only keep cord blood collections that are at least 3 ounces.2
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.
New Jersey Cord Blood Bank can accept donations without pre-registration at participating hospitals that have on-site staff. Donations are also accepted from certain hospitals via partnerships with local charities.
While many diseases can be treated with a cord blood transplant, most require stem cells from another donor (allogeneic). Cord blood cells taken from the patient (autologous) typically contain the same defect or precancerous cells that caused the patient to need the transplant in the first place. Most medical professionals believe the chance that cord blood banking will be utilized by the patient or a close relative is relatively low. Estimates range from 1 out of 1,000 to 1 out of 200,000. From these estimates, privately stored cord blood is not likely to be utilized by the average family. The American Academy of Pediatrics has discouraged cord blood banking for self-use, since most diseases requiring stem cell transplants are already present in the cord blood stem cells. Additionally, a recent study published in Pediatrics indicates that few transplants have been performed using privately stored cord blood. From the responses of 93 transplant physicians, in only 50 cases was privately banked blood used. In 9 of these cases the cord blood was transplanted back into the donor patient (autologous transplant). One of the main selling points of private cord blood banks is the possibility of a future autologous transplant.
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?
