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.
In addition to hematopoietic cells, Mesenchymal cells derived from Wharton’s jelly are useful as feeder layers for the propagation of other stem cell types. For example, equine embryonic stem cell-like cells derived from the inner cell mass were propagated successfully for more than 350 divisions on a feeder layer derived from stem cells isolated from Wharton’s jelly of equine umbilical cords (74). The equine ES-like cells could be maintained without leukemia inhibitory factor (LIF) as long as they were on the cord matrix cells.
MSC-like cells derived from Wharton’s jelly adjacent to umbilical vessels (termed human umbilical cord perivascular cells) cultured in nonosteogenic media nevertheless contained a subpopulation that demonstrated a functional osteogenic phenotype with the elaboration of bone nodules (29); addition of osteogenic supplements further enhanced this population. These findings suggest that cord matrix stem cells, like bmMSCs, are multipotent: capable of making ectoderm- and mesoderm-derived cells.
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.
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).
When a donor signs up with a public bank, the mother must pass a health screening and sign a consent form. After that, the bank processes the application, which makes last-minute donations impossible. However, there are a small number of banks that accept late donor requests.
Complicating matters further, each public bank has its own registry, so transplant centers must search many different databases to find a match for a patient. Currently, a Caucasian patient has an 88 percent chance of finding a cord-blood match through a public-bank registry, and minorities have a 58 percent chance. (Collection hospitals tend to be in areas with higher rates of Caucasian births, and parents from certain ethnic groups are wary of donating for religious or cultural reasons.)

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.
Stem cells are injected into the veins during a peripheral blood transplant, and naturally work their way to the bone marrow. Once there, the new cells start increasing healthy blood count. Compared to bone marrow transplants, cells from peripheral blood are usually faster, creating new blood cells within two weeks.
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.
In the rare event of a processed sample not adhering to quality standards, CBR’s certified genetic counselors will work with potential clients to help them understand their options. Under this scenario, clients will have the option to discontinue storage and receive a refund.
CBR Cord Blood Education Specialists are available 7 days a week (Monday – Friday 6 AM – 9 PM PST and Saturday – Sunday 6 AM – 4 PM PST) to respond to consumer inquiries. In addition, consumers may request to schedule a call with a CBR Cord Blood Education Specialist at a specific date and time.
iPS cells are artificially-made pluripotent stem cells. This technique allows medical staff to create additional pluripotent cells, which will increase treatment options for patients using stem cell therapy in the near future.
Current research aims to answer these questions in order to establish whether safe and effective treatments for non-blood diseases could be developed in the future using cord blood. An early clinical trial investigating cord blood treatment of childhood type 1 diabetes was unsuccessful. Other very early stage clinical trials are now exploring the use of cord blood transplants to treat children with brain disorders such as cerebral palsy or traumatic brain injury. However, such trials have not yet shown any positive effects and most scientists believe much more laboratory research is needed to understand how cord blood cells behave and whether they may be useful in these kinds of treatments
Life Line Stem Cell asks mothers arriving for delivery to donate all perinatal tissue: cord blood, cord tissue, and the placenta. Cord blood donations that are eligible for transplant are sent to a public cord blood bank; the tissue collections go towards research programs.
A nurse from the St. Louis Cord Blood Bank may contact you several weeks after your delivery to check on the health of you and your baby. If your child’s cord blood is identified as a potential match for a patient anytime in the future, an additional phone call will be made to check on the health of your child and family. This call is to obtain and update medical information only. At no time will you or your child be asked for additional blood samples.
If you’re looking to attain cord blood from a public bank, be aware that matched cord blood, as with bone marrow, can be difficult to obtain through a public cord blood bank. Once a match is ascertained, it may take valuable weeks, even months, to retrieve the match, and the cost of acquiring the cord blood from a public bank can be upwards of $40,000. When the newborn’s umbilical cord blood is banked privately, they can be retrieved quickly, and since the parents own the cord blood, banks can perform the retrieval free of charge.

Recently the minimal defining characteristics of MSCs was the subject of a blue ribbon panel of scientists (24). This panel ascribed three defining characteristics to MSCs. First, MSCs are plastic-adherent when maintained in standard culture conditions. Second, MSCs express the cell surface markers CD105, CD73, and CD90 and lack expression of CD45, CD34, CD14 or CD11b, CD79 or CD19, and HLA-DR. Third, MSCs differentiate to osteoblasts, adipocytes, and chondroblasts in vitro. As shown in Table 1, mesenchymal-like cells collected from the umbilical cord, placenta, and from umbilical cord blood, perivascular space, and placenta all share a relatively consistent set of surface markers, which is apparently consistent with the hypothesis that they are MSC-like.
Public cord blood banks do not pay the fees associated with transporting the stored cord blood to the necessary medical facility if they are needed for a transplant, so if this is not covered by your insurance, it could be very costly to use stem cells from a public cord blood bank
Students who register to donate blood three or more times during their high school career earn a Red Cord to wear during graduation events. Seniors must complete the requirement by May 15 (or by the date of their school’s final blood drive of the year, whichever is later).
