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.
If you’re thinking about banking your baby’s cord blood stem cells, one question you’ve probably considered is whether to choose a private or public cord blood bank. As with any major decision in your life, it pays to do your research so you can make the best choice for your family about the future of your baby’s cord blood.
After your unit arrives at ViaCord’s Processing Lab, specialists will process your baby’s stem cells to maximize cell yield. They are then transferred to a transplant-ready cryobag for storage at or below ≤ -170º C (brrr).
Your baby’s cord blood could be a valuable resource for another family. From foundations to non-profit blood banks and medical facilities, there are numerous locations that will collect, process, and use the stem cells from your baby’s cord blood to treat other people.
A limitation of cord blood is that it contains fewer HSCs than a bone marrow donation does, meaning adult patients often require two volumes of cord blood for treatments. Researchers are studying ways to expand the number of HSCs from cord blood in labs so that a single cord blood donation could supply enough cells for one or more HSC transplants.
LifebankUSA seeks mothers in NEW YORK & NEW JERSEY ONLY who will donate both their cord blood and their placenta. The donations support an international registry, clinical trials and research. Donations can be taken from any hospital, but mothers must register at least 8 weeks prior to delivery and pass a health screening.

Stem cells are the next frontier in medicine. Stem cells are thought to have great therapeutic and biotechnological potential. This will not only to replace damaged or dysfunctional cells, but also rescue them and/or deliver therapeutic proteins after they have been engineered to do so. Currently, ethical and scientific issues surround both embryonic and fetal stem cells and hinder their widespread implementation. In contrast, stem cells recovered postnatally from the umbilical cord, including the umbilical cord blood cells, amnion/placenta, umbilical cord vein, or umbilical cord matrix cells, are a readily available and inexpensive source of cells that are capable of forming many different cell types (i.e., they are “multipotent”). This review will focus on the umbilical cord-derived stem cells and compare those cells with adult bone marrow-derived mesenchymal stem cells.
Fortunately, those odds should improve soon. In 2005, Congress passed the Stem Cell Therapeutic and Research Act, which provides $79 million in federal funding to create a centralized cord-blood registry much like the one that exists for bone marrow. The goal is to expand the existing inventory of 45,000 donated cord-blood units to 150,000.
There are some hospitals that have dedicated collections staff who can process mothers at the last minute when they arrive to deliver the baby. However, in the United States that is the exception to the rule.
If someone doesn’t have cord blood stored, they will have to rely on stem cells from another source. For that, we can go back to the history of cord blood, which really begins with bone marrow. Bone marrow contains similar although less effective and possibly tainted versions of the same stem cells abundant in cord blood. Scientists performed the first bone marrow stem cell transplant in 1956 between identical twins. It resulted in the complete remission of the one twin’s leukemia.
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.
In the event your child becomes seriously ill, develops a genetic disorder, illness affecting the immune system or blood-related disease, we ask that you notify the cord blood bank as this could impact the patient receiving your cord blood donation. Contact us for information »
The Medical Letter On Drugs and Therapeutics also recently addressed aspects of public and private cord blood banks, asking the question: “Does Private Banking Make Sense?” After citing various statistics on the actual uses of privately stored cord blood, they concluded that: “At the present time, private storage of umbilical cord blood is unlikely to be worthwhile. Parents should be encouraged to contribute, when they can, to public cord blood banks instead.” [Access The Medical Letter at www.medicalletter.org].
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.
Stem cells are defined simply as cells meeting three basic criteria (illustrated in Fig. 1. First, stem cells renew themselves throughout life, i.e., the cells divide to produce identical daughter cells and thereby maintain the stem cell population. Second, stem cells have the capacity to undergo differentiation to become specialized progeny cells (1). When stem cells differentiate, they may divide asymmetrically to yield an identical cell and a daughter cell that acquires properties of a particular cell type, for example, specific morphology, phenotype, and physiological properties that categorize it as a cell belonging to a particular tissue (2). Stem cells that may differentiate into tissues derived from all three germ layers, for example, ectoderm, endoderm, and mesoderm, are called “pluripotent.” The best example of pluripotent stem cells are the embryonic stem cells (ESCs) derived from the inner cell mass of early embryos. In contrast with ESCs, most stem cells that have been well characterized are multipotent, i.e., they may differentiate into derivatives of two of the three germ layers. The third property of stem cells is that they may renew the tissues that they populate. All tissue compartments contain cells that satisfy the definition of “stem cells” (3), and the rate at which stem cells contribute to replacement cells varies throughout the body. For example, blood-forming stem cells, gut epithelium stem cells, and skin-forming stem cells must be constantly replaced for normal health. In contrast, the stem cells in the nervous system that replace neurons are relatively quiescent and do not participate in tissue renewal or replace neurons lost to injury or disease.
Cord Blood Registry offers two ways to save your newborn’s stem cells, and convenient payment options to fit your family’s needs. CBR recognizes that each family’s budget is unique. As a result, CBR does not take a one-size-fits-all approach to pricing and payments for cord blood and tissue banking. Calculate your stem cell banking costs and CBR will recommend payment plans that may fit your family’s budget.
AutoXpress™ Platform (AXP) cord blood processing results in a red-cell reduced stem cell product. Each sample is stored in a cryobag consisting of two compartments (one major and one minor) and two integrally attached segments used for unit testing.
Umbilical cord blood is being studied for potential use in a wide variety of life-threatening diseases because it is a rich source of blood stem cells. Transplantation of blood stem cells from umbilical cords has been used successfully to treat several pediatric blood diseases, including sickle cell anemia and cancers such as leukemia and lymphoma. This procedure is still considered investigational. There is currently no solid evidence that umbilical cord blood stem cells have the ability to be transformed into other types of cells, such as replacement nerve tissue or myelin-making cells.
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.
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.
Even if you don’t want to store the cord blood, highly consider donating the cord blood to local public banks. This cord blood can help patients that are on waiting lists with diseases such as leukemia.
In 2007, the AAP issued a revised cord-blood-banking policy, that discourages private banks for families who aren’t already facing a health crisis. “These banks prey on parents’ fears of the unknown, and there’s no scientific basis for a number of medical claims they make,” says Bertram Lubin, MD, president and director of medical research for Children’s Hospital Oakland Research Institute, and coauthor for the AAP’s 2006 cord-blood-banking committee.
Several research teams have reported studies in animals suggesting that cord blood can repair tissues other than blood, in diseases ranging from heart attacks to strokes. These findings are controversial: scientists often cannot reproduce such results and it is not clear HOW cord blood may be having such effects. When beneficial effects are observed they may be very slight and not significant enough to be useful for developing treatments. If there are positive effects, they might be explained not by cord blood cells making nerve or heart cells, but by the cells in the cord blood releasing substances that help the body repair damage.
Cord blood is used to treat children with cancerous blood disorders such as leukaemia, or genetic blood diseases like Fanconi anaemia. The cord blood is transplanted into the patient, where the HSCs can make new, healthy blood cells to replace those damaged by the patient’s disease or by a medical treatment such as chemotherapy for cancer.
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.
