The umbilical cord is a rich source of two main types of stem cells: cord blood stem cells and cord tissue stem cells. Through the science of cord blood and cord tissue banking, these stem cells can help nurture life, long after your baby’s birth.
We have shown that porcine UCM stem cells can be xeno-transplanted into nonimmune-suppressed rats, where they engrafted, proliferated in a controlled fashion, and exhibited TH expression in some cells (27). Most recently, our lab (28), and others (31) have reported that UCM cells ameliorate behavioral deficits in the hemi-parkinsonian rat, and UCM cell transplantation resulted in significantly more dopaminergic neurons in the substantia nigra compared with lesioned, nontransplanted rats that responded to the transplant (28). In contrast with our work, in which UCM cells were transplanted without prior differentiation, Fu et al. (31) subjected UCM cells to an in vitro induction protocol utilizing neuronconditioned media, sonic hedgehog, and fibroblast growth factor (FGF)-8 to increase the number of tyrosine hydroxylasepositive cells. After transplantation of these predifferentiated human UCMS cells into hemi-parkinsonian rats, Dr. Fu’s lab reported that they prevented the progressive degeneration/ deterioration in their Parkinson’s disease model.
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.
Finally, the healthy stem cells are placed into long-term cryogenic storage. Compared to other stem cell sources, cord blood units are available very quickly since a doctor can remove them from storage and send them to the transplant hospital within a few days.
Yes, if you have any sick children who could benefit from umbilical cord blood. Public banks such as Carolinas Cord Bank at Duke University and private banks such as FamilyCord in Los Angeles offer programs in which the bank will assist with cord blood processing and storage if your baby has a biological sibling with certain diseases. FamilyCord will provide free cord blood storage for one year. See a list of banks with these programs at parentsguidecordblood.org/help.php.

Is the blood stored as a single unit or in several samples? Freezing in portions is preferred so the blood can be tested for potential transplant use without thawing — and wasting — the entire sample.
Umbilical cord blood was once discarded as waste material but is now known to be a useful source of blood stem cells. Cord blood has been used to treat children with certain blood diseases since 1989 and research on using it to treat adults is making progress. So what are the current challenges for cord blood research and how may it be used – now and in the future?
Another way scientists are working with stem cells is through expansion technologies that spur replication of the cord blood stem cells. If proven effective and approved by the U.S. Food and Drug Administration, these expansion technologies will allow scientists to culture many stem cells from a small sample. This could provide doctors and researchers with enough stem cells to treat multiple family members with one cord blood collection or provide the baby with multiple treatments over time. To better prepare for the day when these expansion technologies are more easily accessible, some cord blood banks have begun to separate their cord blood collections into separate compartments, which can easily be detached from the rest of the collection and used independently. You can learn more about Cryo-Cell’s five-chambered storage bag here.
A major potential application of stem cells in medicine is for “tissue engineering,” in which the ultimate goal is to provide off-the-shelf tissues and organs. UCM cells demonstrate excellent cell growth properties on bioabsorbable polymer constructs (75). UCM cells were used to seed blood vessel conduits fashioned from rapidly bioabsorbable polymers and grown in vitro in a pulse duplicator bioreactor (76). Recently, living patches engineered from UCMS cells and cord-derived endothelial precursor cells have been described for potential use in human pediatric cardiovascular tissue engineering (77,78).

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.
More cord blood donations are desperately needed to cover the transplant needs of adults. Cord blood donations from newborns of diverse ethnic and racial backgrounds are especially needed. Tissue types are inherited, so patients who need a stem cell transplant are more likely to find a matched cord blood unit from someone in their own race or ethnic group.
Medical staff at the public cord blood bank will check to see if you can donate. If you have had a disease that can be given to another person through blood-forming cells, such as hepatitis B, hepatitis C, or HIV (the AIDS virus), you will likely not be able to donate. However, other medical reasons may still allow you to donate, for example, hepatitis A or diabetes only during your pregnancy (gestational diabetes). The staff at the public cord blood bank will tell you.
While the stem cell count is smaller during a cord blood transplant, these cells multiply quickly, and researchers are studying new methods to increase cells naturally. Compared to bone marrow, cord blood cells multiply faster and don’t require an exact match type to complete a successful transplant. Some techniques medical experts are testing to increase the amount of stem cells include:
Cord blood is also being studied as a substitute for normal blood transfusions in the developing world. More research is necessary prior to the generalized utilization of cord blood transfusion.
When a patient needs bone marrow for a transplant, stem cells are thawed and injected into the bloodstream. The cells then make their way to the bone marrow, and start producing new blood cells – this process usually takes a few weeks.
As noted earlier, with better matching, there is a greater chance of success and less risk of graft-versus-host disease (GvHD) in any stem cell transplant. With cord blood, the baby’s own cells are always a perfect match and share little risk. When using cord blood across identical twins, there is also a very low chance of GvHD although mutations and biological changes caused by epigenetic factors can occur. Other blood-related family members have a 35%–45% chance of GvHD, and unrelated persons have a 60%–80% chance of suffering from GvHD.
Life Line Stem Cell asks mothers arriving for delivery to donate all perinatal tissue: cord blood, cord tissue, and the placenta. Cord blood donations that are eligible for transplant are sent to a public cord blood bank; the tissue collections go towards research programs.
Founded in 1992, CBR has stored more than 600,000 cord blood and cord tissue collections from 3,500 hospitals in over 100 countries and partnered with institutions to establish multiple FDA-regulated clinical trials. CBR has helped more than 400 families use their cord blood stem cells for established and experimental medical treatments, more than any other family cord blood bank. CBR’s goal is to expand the potential scope of newborn stem cell therapies that may be available to patients and their families.
With the consent of the parents, blood can be collected from the umbilical cord of a newborn baby shortly after birth. This does not hurt the baby or the mother in any way, and it is blood that would otherwise be discarded as biological waste along with the placenta (another rich source of stem cells) after the birth.
CBR collection kits have been designed to shield the samples from extreme temperatures (shielding for more than 1 hour at extreme hot and cold). Samples remain at room temperature and are shipped directly to the CBR lab for processing.
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).
The mother signs an informed consent which gives a “public” cord blood bank permission to collect the cord blood after birth and to list it on a database that can be searched by doctors on behalf of patients. The cord blood is listed purely by its genetic type, with no information about the identity of the donor. In the United States, Be The Match maintains a national network of public cord blood banks and registered cord blood donations. However, all the donation registries around the world cooperate with each other, so that a patient who one day benefits from your child’s cord blood may come from anywhere. It is truly a gift to the benefit of humankind.
In addition to hematopoietic cells, Mesenchymal cells derived from Wharton’s jelly are useful as feeder layers for the propagation of other stem cell types. For example, equine embryonic stem cell-like cells derived from the inner cell mass were propagated successfully for more than 350 divisions on a feeder layer derived from stem cells isolated from Wharton’s jelly of equine umbilical cords (74). The equine ES-like cells could be maintained without leukemia inhibitory factor (LIF) as long as they were on the cord matrix cells.
Preserving stem cells does not guarantee that the saved stem cells will be applicable for every situation. Ultimate use will be determined by a physician. Please note: Americord Registry’s activities are limited to collection of umbilical cord tissue from autologous donors. Americord Registry’s possession of a New York State license for such collection does not indicate approval or endorsement of possible future uses or future suitability of cells derived from umbilical cord tissue.
Collected cord blood is cryopreserved and then stored in a cord blood bank for future transplantation. Cord blood collection is typically depleted of red blood cells before cryopreservation to ensure high rates of stem cell recovery.
* Disclaimer: Banking cord blood does not guarantee that treatment will work and only a doctor can determine when it can be used. Cord tissue stem cells are not approved for use in treatment, but research is ongoing.

Clearly, it is advantageous to save cord blood stem cells, but it can be confusing to decide where to store them. There are currently two options: public cord blood banks and private cord blood banks. Public and private banks serve very different purposes, and it is important to know which type of bank would be more beneficial to you and your family.

Clinical Trials More likely to be used in clinical trials to potentially treat strokes, heart attacks, diabetes, cerebral palsy, autism and a range of other serious medical conditions Less likely to be available to the donor or family members for use in clinical trials More likely to be used in clinical trials for range of other serious medical conditions Less likely to be available for use in clinical trials
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.
There are no health risks related to cord blood collection. Cord blood is retrieved from the umbilical cord after it has been cut, thus preventing any pain, discomfort, or harm. This process is completely safe.
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.
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.
Since 1989, umbilical cord blood has been used successfully to treat children with leukaemia, anaemias and other blood diseases. Researchers are now looking at ways of increasing the number of haematopoietic stem cells that can be obtained from cord blood, so that they can be used to treat adults routinely too.
There’s a network of public cord blood banks in the United States that can take your donation. Most public banks are nonprofit organizations, and all public cord blood banks must meet stringent quality standards.
Cord Blood Registry (CBR) is a private bank that offers collection and long-term storage of both cord blood and cord tissue. With more than 700,000 stored units, CBR is one of the largest of the cord blood banks.
Chloe Savannah Metz’ mother donated her baby girl’s cord blood to the NCBP in December 2000. “Many thanks to the New York Blood Center for giving us the opportunity to donate our cord — we hope to give someone a second chance!” – Christine Metz
If everyone donated cord blood to public registries for the ‘common good’ this would increase the chances of someone benefiting from a double cord blood transplant. This far outweights the actual probability of the person who donated the sample being able to usefully use it for themself.
The procedure for obtaining the cord blood involves clamping the umbilical cord at the time of birth. The small amount of blood remaining in the umbilical cord is drained and taken to a cord blood bank. It is free to donate.

Your baby’s umbilical cord is made up of tissue and contains blood. Both cord blood and cord tissue are rich sources of powerful stem cells. Cord blood stem cells are currently used in transplant medicine to regenerate healthy blood and immune systems. These cells are being researched for their ability to act like our body’s own personal repair kit and may be able to help our bodies heal in new ways.
Most cells can make copies only of themselves. For example, a skin cell only can make another skin cell. Hematopoietic stem cells, however, can mature into different types of blood cells in the body. Hematopoietic stem cells also are found in blood and bone marrow in adults and children.
There is often confusion over who can use cord blood stem cells in treatment — the baby they were collected from or a sibling? The short answer is both, but it very much depends on the condition being treated. And it’s ultimately the treating physician’s decision.
