Stay up on the latest stem cell developments with our stem cell news blog. Read about the newest trials that are underway, how current trials are faring and new ways that cord blood and tissue stem cells are being used in regenerative therapies. For doctors and researches, the Stem Cell Insider provides a more detailed look at the latest stem cell news and showcases the latest advancements in our products to help ensure stem cells preserved with us are viable and pure.
A typical cord blood collection only contains enough stem cells to transplant a large child or small adult. This website has a page explaining the optimum transplant dose. At one time it was believed that cell dose limitations restricted the use of cord blood transplants to children. In recent years growing numbers of adults are also receiving cord blood transplants, either by growing the cells in a lab prior to transplant or by transplanting more than one cord blood unit at a time. More information about these trials is available on the web page about Research on Cord Blood Transplants.
A number of private for-profit companies have been established that encourage parents to bank their children’s cord blood for their own autologous use or for directed donor allogeneic use for a family member should the need arise. Parents have been encouraged to bank their infants’ cord blood as a form of “biological insurance.” Physicians, employees, and/or consultants of such companies may have potential conflicts of interest in recruiting patients because of their own financial gain. Annual disclosure of the financial interest and potential conflicts of interest must be made to institutional review boards that are charged with the responsibility of mitigation of these disclosures and risks. Families may be vulnerable to the emotional effects of marketing for cord blood banking at the time of birth of a child and may look to their physicians for advice. No accurate estimates exist of the likelihood of children to need their own stored cord blood stem cells in the future. The range of available estimates is from 1 in 1000 to more than 1 in 200000.51 The potential for children needing their own cord blood stem cells for future autologous use is controversial presently.51 There also is no evidence of the safety or effectiveness of autologous cord blood stem cell transplantation for the treatment of malignant neoplasms.51 Indeed, there is evidence demonstrating the presence of DNA mutations in cord blood obtained from children who subsequently develop leukemia.52 Thus, an autologous cord blood transplantation might even be contraindicated in the treatment of a child who develops leukemia.
Blood naturally starts to clot when its outside the body. An anticoagulant is used to help prevent the cord blood from clotting while it is in transit to the laboratory for processing. CBR deliberately chose to use lyophilized (dry) heparin as the anticoagulant because of some potential advantages, including:
Cord blood can only be collected at birth, that’s why it’s important to do your research well before your baby’s due date. Watch this short video to learn exactly how cord blood is collected, processed and stored.
Public cord blood companies are mostly nonprofit companies that are traded publicly, and doctors can utilize matching cord blood in these banks for treating their patients, even if the blood is not their own.
These are diagnoses for which stem cell treatments are being studied either in the laboratory with cell cultures or in animals that mimic the human disease. The experimental therapies are not yet in human clinical trials. In experimental research, it is often not clear whether an eventual therapy, if developed, would be Autologous or Allogeneic.
Both public and family cord blood banks must register with the US Food and Drug Administration (FDA), and since Oct. 2011 public banks also need to apply for an FDA license. All cord blood banks are required by federal law to test the blood of the mother for infectious diseases. At public banks the screening is usually more extensive, similar to the tests performed when you donate blood. The typical expense to a public bank is $150 per unit.
Our annual storage fee is due every year on the birth date of the child and covers the cost of storage until the following birthday. The fee is the same $150 for both our standard and our premium cord blood services. The annual cord tissue storage fee is an additional $150.
Public cord blood banking is free, but you give up your rights to the cord blood stem cells at the time of donation. Just like donating to a blood bank, this means your donation would be owned by the public cord blood bank and not by you. Your donated cord blood stem cells can be used for medical research or could possibly save a life through a transplant. Public cord blood banks release your child’s stem cells when a good match from a registry is identified.1
A “clinical trial” is a study in human patients for an emerging therapy that has not been adopted as standard therapy. This website has pages that enable patients to search worldwide for currently recruiting clinical trials with ether cord blood or umbilical cord tissue MSC. The table below checks off all diagnoses that have ever been treated in clinical trials with cord blood or cord tissue, regardless of whether the trials are still open.
Cord blood–banking recruitment practices should be developed with an awareness of the possible emotional vulnerability of pregnant women and their families and friends. Efforts should be made to minimize the effect of this vulnerability on cord blood–banking decisions.
Cord blood donation should be encouraged when the cord blood is stored in a bank for public use. Parents should recognize that genetic (eg, chromosomal abnormalities) and infectious disease testing is performed on the cord blood and that if abnormalities are identified, they will be notified. Parents should also be informed that the cord blood banked in a public program may not be accessible for future private use.

Cord Blood Registry is a cord blood storage company that collects, processes and stores stem cells to help families with medical needs later in life. Founded in 1992, it is the world’s largest newborn stem cell company.
This is only the beginning. Newborn stem cell research is advancing, and may yield discoveries that could have important benefits for families. CBR’s mission is to support the advancement of newborn stem cell research, with the hope that the investment you are making now will be valuable to your family in the future. CBR offers a high quality newborn stem cell preservation system to protect these precious resources for future possible benefits for your family.

In 1988, a 5-year-old named Matthew with a rare type of anemia received umbilical cord blood cells from his newborn sister, who didn’t have the disease. That transfer, called an umbilical cord blood transplant, worked, and the boy was soon free of the disease.
In a number of genetic, hematologic, immunologic, metabolic, and oncologic disorders, reconstitution of bone marrow (transplantation) can be a potentially life-saving procedure.1–16 Allogeneic (related or unrelated) or autologous (self) bone marrow or peripheral blood stem cells are the usual sources of hematopoietic progenitor cells to achieve this goal. If autologous stem cells are not available or cannot be used, the best option for successful reconstitution therapy is to secure stem cells from an HLA-matched sibling.1,3,11 Close matching confers a higher probability of successful engraftment and minimizes the risk of potentially fatal graft-versus-host disease. Unfortunately, there is only a 25% chance for identifying a full HLA match in a sibling donor.17,18
A person will always be a 100% match to his or her cord blood, which is the best fit as there are some conditions that can only be treated with one’s own cord blood stem cells (or a perfect match). However, other conditions can be treated using donor stem cells that are partial genetic matches.
If you intend donating umbilical cord blood for preservation and later use, you should let your doctor know by your 34th week so that they can help make any arrangements with a cord blood bank. Once you and your doctor have decided on which cord blood bank to use, you will often be sent informational reading materials from the cord blood bank for further education regarding the process of cord blood harvesting.
Another important disadvantage that is not well understood by the general public is the limited use of an infant’s own umbilical cord blood stem cells later in life, called an autologous transplant. Commercial cord blood banks often advertise the banking of the infant’s cord blood as “biologic insurance.” However, the chance that a child would be able to use his or her own cord blood is extremely small: from a 1:400 to a 1:200,000 chance over the child’s lifetime (Sullivan, 2008). In fact, there are certain instances in which the use of one’s own umbilical cord blood is contraindicated, as in cases when the defect is of a genetic origin. For example, autologous cord blood stem cells cannot be used to treat malignant cancers such as leukemia because the genetic mutations for the cancer already exist on the DNA of the cord blood. Using one’s own stem cells would be, in effect, “contaminating” oneself with the same disease process (Percer, 2009).
4. Parkinson’s disease. Stem cells may also help those who suffer from Parkinson’s, a neurodegenerative disorder that can cause tremors, stiffness, and other movement and speech problems. Studies show that embryonic stem cells can give rise to the dopamine-making neurons that Parkinson’s patients lack. When transplanted into rodents with a Parkinson’s-like disorder, those replacement brain cells improved the animals’ motor function.
A few years ago, cord blood was simply discarded as medical waste after a birth. However, in the past few years, doctors have recognized that the stem cells have unique qualities which can be used in the treatment of certain cancers. The most common medical use is for transplantation in many situations where bone marrow is considered. In the future, it is possible that scientists will discover more diseases that can be cured with cord blood.
The main disadvantage of cord blood transplants is that they take at least a week longer to “engraft”, which means repopulate the patient’s blood supply so that cell counts reach minimum acceptable levels. The longer engraftment time is a risk because it leaves the patient vulnerable to a fatal infection for a longer time.
Many private banking proponents think that by storing your baby’s cord blood stem cells, you are positioning your family with a form of biological insurance in the event that your child or a close family member has a treatable disease.
Cord blood contains stem cells that can save lives. Patients requiring a stem cell transplant will receive cells from one of three sources: bone marrow, circulating blood, or umbilical cord blood. The first two exist in all healthy adults, but cord blood can only be harvested and stored at birth
Accurate information about the potential benefits and limitations of allogeneic and autologous cord blood banking and transplantation should be provided. Parents should be informed that autologous cord blood would not be used as a stem cell source if the donor developed leukemia later in life. Parents should recognize that there are no scientific data to support the claim that autologous cord blood is a tissue source proven to be of value for regenerative medical purposes. The current standard uses of cord blood transplantation are listed in Table 1.
