Beyond these blood-related disorders, the therapeutic potential of umbilical cord blood stem cells is unclear. No therapies for non-blood-related diseases have yet been developed using HSCs from either cord blood or adult bone marrow. There have been several reports suggesting that umbilical cord blood contains other types of stem cells that are able to produce cells from other tissues, such as nerve cells. Some other reports claim that umbilical cord blood contains embryonic stem cell-like cells. However, these findings are highly controversial among scientists and are not widely accepted.
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.
Cord Blood Registry’s Newborn Possibilities Program® serves as a catalyst to advance newborn stem cell medicine and science for families that have been identified with a medical need to potentially use newborn stem cells now or in the near future. NPP offers free cord blood and cord tissue processing and five years of storage to qualifying families. To date, the Newborn Possibilities Program has processed and saved stem cells for nearly 6,000 families.
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 literature review revealed a question about the stability of umbilical cord cells in culture. Two groups found that the cell surface marker expression shifted over passage (28,29). Sarugaser’s (29) work indicated that HLA-1 was lost as a result of cryopreservation. Whereas, umbilical cord perivascular cells lost cell surface staining for HLA-1 with freeze–thaw, HLA-1 surface staining was consistent out to passage 5 for cells maintained in culture. In contrast, Weiss et al. (28) reported a decrease in the percentage of cells expressing CD49e and CD105 when human UCM cells were maintained in culture for passage 4–8 and no significant changes in HLA-1 expression. This question about the stability of surface marker expression may indicate that epigenetic phenomena associated with cell culture are influencing the cord MSC-like cells. Further characterization of the cord MSC-like cells is needed to understand the mechanisms of these changes.
The syringe or bag should be pre-labeled with a unique number that identifies your baby. Cord blood may only be collected during the first 15 minutes following the birth and should be processed by the laboratory within 48 hours of collection.
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 ]

The stored blood can’t always be used, even if the person develops a disease later on, because if the disease was caused by a genetic mutation, it would also be in the stem cells. Current research says the stored blood may only be useful for 15 years.
Find a public bank that participates with your hospital. Public banks usually partner with specific hospitals, so you will usually only have one choice. If your hospital doesn’t partner with a public bank, or if you don’t like the facility they work with, several private banks offer a donation option, which means public banking may still be possible.
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.

Another type of cell that can also be collected from umbilical cord blood are mesenchymal stromal cells. These cells can grown into bone, cartilage and other types of tissues and are being used in many research studies to see if patients could benefit from these cells too.
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.
Pregnant women sometimes have questions or concerns regarding umbilical cord blood donation. Two common questions are: Can their infant’s cord blood be used to benefit MS research? Another question: Is it worthwhile to “bank” their infant’s umbilical cord blood for the benefit of a family member who might need the umbilical stem cells for future treatment of their MS?
“This reanalysis supports several previously expressed opinions that autologous [to use one’s OWN cells] banking of cord blood privately as a biological insurance for the treatment of life-threatening diseases in children and young adults is not clinically justified because the chances of ever using it are remote. The absence of published peer-reviewed evidence raises the serious ethical concern of a failure to inform prospective parents about the lack of future benefit for autologous cord banking … Attempts to justify this [commercial cord blood banking] are based on the success of unrelated public domain cord banking and allogeneic [using someone ELSE’S cells] cord blood transplantation, and not on the use of autologous [the person’s OWN cells] cord transplantation, the efficacy of which remains unproven”.
The first cord blood transplant was performed in Paris on October 6, 1988. Since that time, over 1 million cord blood units have been collected and stored in public and family banks all over the world.
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.
Hematopoietic stem cells can be used to treat more than 70 types of diseases, including diseases of the immune system, genetic disorders, neurologic disorders, and some forms of cancer, including leukemia and lymphoma. For some of these diseases, stem cells are the primary treatment. For others, treatment with stem cells may be used when other treatments have not worked or in experimental research programs.
While donating cord blood is honorable, there is a lot people do not know about the public option. Most public cord blood banks have a limited number of collection sites, and they only retain a small number of collections because of volume and other criteria that must be met. Once cord blood is donated, it is highly unlikely that the donation can ever be attained by the donor or his or her family if the need arises. In addition, it may be hard to find another viable match from what is publically available. While donating is free, retreiving a cord blood sample from a public cord blood bank is not and pales in comparison to the overall cost of privately banking cord blood. These are just some of the reasons why privately banking cord blood may be a better option for some families.
I am currently 38 years old and I would like to have my blood and it’s stem cells harvested via peripheral blood draw to be stored in definitely. Do you offer this service? If so, how can I arrange for my family?
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.
Cord blood (short for umbilical cord blood) is the blood that remains in the umbilical cord and placenta post-delivery. At or near term, there is a maternal–fetal transfer of cells to boost the immune systems of both the mother and baby in preparation for labor. This makes cord blood at the time of delivery a rich source of stem cells and other cells of the immune system. Cord blood banking is the process of collecting the cord blood and extracting and cryogenically freezing its stem cells and other cells of the immune system for potential future medical use.
Bone marrow transplantation, also called hemopoietic stem cell transplantation, is under investigation for the treatment of severe forms of multiple sclerosis. The long-term benefits of this experimental procedure have not yet been established. In this procedure, the individual receives grafts of his or her own blood stem cells, and thus donor stem cells are not used or needed.
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.
Cord blood has an abundance of stem cells and immune system cells, and the medical uses of these cells has been expanding at a rapid pace. As these cells help the body re-generate tissues and systems, cord blood is often referred to as a regenerative medicine.
