In addition to their immune-suppressive properties, MSCs appear to exhibit a tropism for damaged or rapidly growing tissues. For example, following injection into the brain, MSCs migrate along known pathways when injected into the corpus striatum (44). MSCs migrated throughout forebrain and cerebellum, integrated into central nervous system cytoarchitecture, and expressed markers typical of mature astrocytes and neurons after injection into the lateral ventricle of neonatal mice (45). MSCs injected into injured spinal cord were found to form guiding “cord,” ushering in regenerating fibers (46). MSCs may assist with regeneration in stroke (47–51) or myocardial ischemia (52–55) by release of trophic factors such as brain-derived neurotrophic factor, glial cell line-derived neurotrophic factor, or angiogenic factors (56–61).
The Doneses were shocked, however, when doctors told them that Anthony’s cord blood couldn’t be used because the cells contained the same genetic defect that caused his condition. “The materials provided by the bank said this was Anthony’s life insurance and could save him if he needed it. They never mentioned that the cells could be diseased. We felt duped,” Tracey says. The Long Island, New York, couple has since filed a lawsuit against the bank alleging false advertising and consumer fraud.
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.
A cord blood bank may be private (i.e. the blood is stored for and the costs paid by donor families) or public (i.e. stored and made available for use by unrelated donors). While public cord blood banking is widely supported, private cord banking is controversial in both the medical and parenting community. Although umbilical cord blood is well-recognized to be useful for treating hematopoietic and genetic disorders, some controversy surrounds the collection and storage of umbilical cord blood by private banks for the baby’s use. Only a small percentage of babies (estimated at between 1 in 1,000 to 1 in 200,000) ever use the umbilical cord blood that is stored. The American Academy of Pediatrics 2007 Policy Statement on Cord Blood Banking stated: “Physicians should be aware of the unsubstantiated claims of private cord blood banks made to future parents that promise to insure infants or family members against serious illnesses in the future by use of the stem cells contained in cord blood.” and “private storage of cord blood as ‘biological insurance’ is unwise” unless there is a family member with a current or potential need to undergo a stem cell transplantation. The American Academy of Pediatrics also notes that the odds of using a person’s own cord blood is 1 in 200,000 while the Institute of Medicine says that only 14 such procedures have ever been performed.
Haematopoietic stem cells (HSCs) can make every type of cell in the blood – red cells, white cells and platelets. They are responsible for maintaining blood production throughout our lives. They have been used for many years in bone marrow transplants to treat blood diseases.
The work from Dr. Verfaillie’s lab on the multipotent adult progenitor cell (MAPC) has received much attention (15,16,18–22). Their findings indicate that the MAPC is pluripotential and slightly enigmatic, as it appears after extensive passage in cell culture. Similarly, in umbilical cord blood, Kogler et al. (17,23) identified a cell that they call the universal somatic stem cell (USSC). The USSC is another rare cell (average of 16 cells in initial isolate; able to isolate USSC in 50% of the cords attempted). The USSC, like the MAPC, offers much promise as an embryo-safe pluripotent cell. Widespread acceptance of these two cells will come when the methods for their isolation become robust such that any laboratory can isolate them and contribute to the field.
The members of the team at CORD:USE are credited for discovering the field of cord blood banking and transplantation. With more than 150 years of combined knowledge and experience, our team members are universally recognized as pioneers and leading experts in the field.
Private (commercial) cord banks will store the donated blood for use by the donor and family members only. They can be expensive. These banks charge a fee for processing and an annual fee for storage.
MSCs are reported to have immune-suppressive effects. To comment human fetal and adult MSCs are not inherently immunostimulatory in vitro and fail to induce proliferation of allogeneic lymphocytes (37–39; for review, see ref. 40). In one human case, fully mismatched allogeneic fetal liver-derived MSCs were transplanted into an immunocompetent fetus with osteogenesis imperfecta in the third trimester of gestation (41). No immunoreactivity was observed when patient lymphocytes were re-exposed to the graft in vitro, indicating that MSCs can be tolerated when transplanted across MHC barriers in humans. Similarly, after intrauterine transplantation of human MSCs into sheep, the cells persisted long-term and differentiated along multiple mesenchymal lineages (42). Instead, the cells are immunosuppressive and reduce lymphocyte proliferation and the formation of cytotoxic T-cells and natural killer cells when present in mixed lymphocyte cultures. The mechanism whereby MSCs suppress lymphocyte proliferation is still largely unknown but appears to, at least in part, be mediated by a soluble factor. Several factors, including MSC-produced prostaglandin E2, indoleamine 2,3-dioxygenase-mediated tryptophan depletion, transforming growth factor-β1, and hepatocyte growth factor have been proposed to mediate the suppression, but the data remain controversial.
Georgia Regents University is conducting an FDA-regulated phase I/II clinical trial to assess whether an infusion of autologous stem cells derived from their own cord blood can improve the quality of life for children with cerebral palsy.
Luckily for expectant parents, cord blood can be easily collected at the baby’s birth via the umbilical cord with no harm to the mother or baby. This is why pregnancy is a great time to plan to collect and bank a baby’s cord blood.
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.
Anthony’s doctors found a match for him through the New York Blood Center’s National Cord Blood Program, a public cord blood bank. Unlike private banks, public banks do not charge to collect cord blood, they charge a patients insurance company when cells are used. And once it is entered in the public system, the blood is available to anyone who needs it.
Private cord blood banking can benefit those with a strong family history of certain diseases that harm the blood and immune system, such as leukemia and some cancers, sickle-cell anemia, and some metabolic disorders. Parents who already have a child (in a household with biological siblings) who is sick with one of these diseases have the greatest chance of finding a match with their baby’s cord blood. Parents who have a family history of autism, Alzheimer’s, and type 1 diabetes can benefit from cord blood. Although these diseases aren’t currently treated with umbilical cord steam cells, researchers are exploring ways to treat them (and many more) with cord blood.
Meet Dylan. Diagnosed with leukemia at just 8 weeks old, he received a life-saving cord blood transplant at 6 months old. Today, Dylan is growing up strong, going to school, travelling with his family and just having fun being a kid!
However, parents should know that a child’s own cord blood (stored at birth), would rarely be suitable for a transplant today. It could not be used at present to treat genetic diseases, for example, because the cord blood stem cells carry the same affected genes and. if transplanted, would confer the same condition to the recipient. (See the story of Anthony Dones.) In addition, most transplant physicians would not use a child’s own cord blood to treat leukemia. There are two reasons why the child’s own cord blood is not safe as a transplant source. First, in most cases of childhood leukemia, cells carrying the leukemic mutation are already present at birth and can be demonstrated in the cord blood. Thus, pre-leukemic cells may be given back with the transplant, since there is no effective way to remove them (purge) today. Second, in a child with leukemia, the immune system has already failed to prevent leukemia. Since cord blood from the same child re-establishes the child’s own immune system, doctors fear it would have a poor anti-leukemia effect.

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?
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?
Your baby’s cord blood tissue, or umbilical cord lining, holds different stem cells. Researchers are breaking new ground with these cells, with applications which could prove to be beneficial in the future for the treatment of many more common diseases.
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?
While all three stem cell sources are used in similar procedures, they each have advantages and drawbacks. Bone marrow transplants are the traditional form of therapy, but peripheral blood cells are becoming more popular, since doctors often get more stem cells from the bloodstream.
Operating both a family and public bank, CORD:USE cord blood units have been used in more transplants in the past 9 years than the two largest family cord blood banks have been involved in over their combined past 43 years of business2,3.
In addition to the benefits related to transplanting HSCs derived from cord blood, HSCs are relatively easy to isolate, giving them an advantage over other adult stem cell types. Cord blood HSCs are also believed to have greater plasticity than HSCs found in bone marrow or the blood stream. The limits and possibilities of using HSCs to repair tissues and treat non-blood related disorders are currently being studied.
In an allogenic transplant, another person’s stem cells are used to treat a child’s disease. This kind of transplant is more likely to be done than an autologous transplant. In an allogenic transplant, the donor can be a relative or be unrelated to the child. For an allogenic transplant to work, there has to be a good match between donor and recipient. A donor is a good match when certain things about his or her cells and the recipient’s cells are alike. If the match is not good, the recipient’s immune system may reject the donated cells. If the cells are rejected, the transplant does not work.
Cord blood donation doesn’t cost anything for parents. Public cord blood banks pay for everything which includes the collection, testing, and storing of umbilical cord blood. This means that cord blood donation is not possible in every hospital.
