In recent years, umbilical cord blood has been used successfully to treat a variety of pediatric genetic, hematologic and oncologic disorders. This advance has resulted in both not-for-profit and for-profit cord blood banking programs. The AAP’s statement is intended to help guide physicians in answering parents’ questions about cord blood banking.
The most obvious argument against is that the odds of needing cord blood for medical treatment is very, very slim. Below is a news release on a policy published in the July,1999 issue of Pediatrics, the peer-reviewed scientific journal of the American Academy of Pediatrics (AAP):
In order to preserve more types and quantity of umbilical cord stem cells and to maximize possible future health options, Cryo-Cell’s umbilical cord tissue service provides expectant families with the opportunity to cryogenically store their newborn’s umbilical cord tissue cells contained within substantially intact cord tissue. Should umbilical cord tissue cells be considered for potential utilization in a future therapeutic application, further laboratory processing may be necessary. Regarding umbilical cord tissue, all private blood banks’ activities for New York State residents are limited to collection, processing, and long-term storage of umbilical cord tissue stem cells. The possession of a New York State license for such collection, processing and long-term storage does not indicate approval or endorsement of possible future uses or future suitability of these cells.
With President Obama’s lifting of the ban on federal funding for embryonic stem cell research, scientists had necessary funding for developing medical treatments, in which case with a new Trump’s administration it might be different now.
Cryo-Cell, Viacord, and Cord Blood Registry are three of the oldest and largest private cord blood banks in the United States. They’ve been storing cord blood since the early ’90s, and they’re all accredited by the AABB. Cryo-Cell is located in Oldsmar, Florida; Viacord in Cambridge, Massachusetts; and Cord Blood Registry in San Bruno, California. Each of these banks has its own private labs that test for syphilis, HIV, hepatitis, cytomegalovirus, and human T-cell lymphotrophic virus (considered a precursor to leukemia); the testing is included in their registration fee.
Stem cells are able to transform into other types of cells in the body to create new growth and development. They are also the building blocks of the immune system. The transformation of these cells provides doctors with a way to treat leukemia and some inherited health disorders.

Therapies with cord blood have gotten more successful. “The outcomes of cord blood transplants have improved over the past 10 years because researchers and clinicians have learned more about dosing cord blood, picking better matches, and giving the patient better supportive care as they go through the transplant,” says Joanne Kurtzberg, M.D., director of the pediatric bone marrow and stem cell transplant program at Duke University.
For much of pregnancy, the umbilical cord is the lifeline of a fetus, tethering it to the placenta. Snaking through the nearly 2-feet-long cord, there’s a vein ferrying nutrients and oxygen from mom’s blood (via the placenta), plus two arteries carrying oxygen- and nutrient-depleted blood from the fetus back to mom. Because mother’s blood and fetal blood don’t actually mix much, the blood in the placenta and umbilical cord at birth belongs mainly to the fetus.
An additional cost that is borne only by public banks is the “HLA typing” that is used to match donors and patients for transplants. This is an expensive test, running about $75 to $125 per unit. Family banks always defer this test until it is known whether a family member might use the cord blood for therapy.
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.
You can also support your local research and academic institutions that are accepting cord blood donations. Stem cell research has become a provocative debate because of the ethical disagreements around embryonic stem cells. UCB avoids the debate entirely while still providing valuable stem cells in the quest to cure disease and mitigate human suffering.
Prior to freezing the cells, samples are taken for quality testing. Banks measure the number of cells that are positive for the CD34 marker, a protein that is used to estimate the number of blood-forming stem cells present. Typical cost, $150 to $200 per unit. They also measure the number of nucleated cells, another measure of stem cells, both before and after processing to determine the cell recovery rate. Typical expense, $35 per unit. A portion of the sample is submitted to check that there is no bacterial or fungal contamination. Typical expense, $75 per unit. Public banks will also check the ability of the sample to grow new cells by taking a culture called the CFU assay. Typical expense, $200 to $250 per unit.
Umbilical cord blood stem cells are different from embryonic stem cells. Umbilical cord blood stem cells are collected by your ob-gyn or a nurse from the umbilical cord after you give birth (but before your placenta is delivered). Embryonic stem cells are collected when a human embryo is destroyed.
CBR’s quality control team performs over 5 million sample checks per year which includes 3 million temperature checks, 20,000 environmental sterility tests, and 95 control checks on each sample to ensure processes are working correctly so that your family’s stem cells are kept protected. At CBR we take the safe storage of your stem cells seriously.
*Fee schedule subject to change without notice. If a client has received a kit and discontinues services prior to collection, there is no cancelation fee if the kit is returned unused within two weeks from cancelation notice; otherwise, a $150 kit replacement fee will be assessed. †Additional courier service fee applies for Alaska, Hawai’i and Puerto Rico. ††Applies to one-year plan and promotional plan only. After the first year, an annual storage fee will apply. Cryo-Cell guarantees to match any written offer for product determined to be similar at Cryo-Cell’s sole discretion. ** Promotional Plan cannot be combined with any other promotional offers, coupons or financing.
The cord blood collection process is simple, safe, and painless. The process usually takes no longer than five minutes. Cord blood collection does not interfere with delivery and is possible with both vaginal and cesarean deliveries.
Despite the benefits of using umbilical cord blood stem cells for transplant, the process also has some disadvantages (see Table 3). For stem cell transplants to be successful, measurable signs of engraftment must occur. Engraftment is the opposite of rejection and indicates that the stem cell transplant is “working.” Two measurable signs of engraftment are the recovery of both neutrophil (a type of white blood cell) and platelet (a clotting factor) production. These two clinical signs of recovery take longer to occur in umbilical cord blood stem cell transplants than in bone marrow stem cell transplants. In other words, the lab values for white blood cell production and platelet production take longer to increase after umbilical cord blood stem cell transplants than after bone marrow stem cell transplants (Hess, 1997; Moise, 2005).
CBR presented data, in the form of a poster, at the 2008 joint annual meeting of the Center for International Blood and Marrow Transplant Research (CIBMTR) and the American Society of Blood and Marrow Transplants (ASMBT). In the poster, CBR showed results obtained during implementation of the AXP System. The published abstract reported that, under the controlled conditions of the study, the average recovery rate of the mononucleated cell (MNC) population was approximately 99% (specifically 98.7%). The results presented at this meeting are consistent with some of the high MNC recovery rates reported by other groups that have adopted AXP System (Rubinstein P. Cord blood banking for clinical transplantation. Bone Marrow Transplantation. 2009;44:635-642).
4. If your family, especially your children, are of mixed ethnic background, it may be impossible to find an adult bone marrow donor who is a perfect match. In that event, cord blood from even a partially matched sibling would be invaluable if a stem cell transplant is necessary.
