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.
Over 95% of newborns’ cord blood stem cells fall into this category. It is unfortunate that public banking is not readably available and private banking is so expensive. Some industry leaders believe that as the industry grows, banking or donating cord blood will be as common as it is uncommon today.

Umbilical cord blood was once thought of as a waste product of the birthing experience, but now it is valued for its content of stem cells. Today, more than 20 years after the first successful umbilical cord blood stem cell transplant, more families are seeking information about whether or not to invest in saving their newborn’s umbilical cord blood. Saving the cord blood in public banks is a worthy undertaking for any family. It is recommended that expectant families only consider cord blood banking in private banks when they have a relative with a known disorder that is already treatable by stem cell transplants. Moreover, expectant families should not rely on commercial cord blood banks as their sole source of information about cord blood banking.
The evolution from pluripotent stem cells down to blood stem cells is currently poorly understood. The latest indication is that, under the right conditions, stem cells in cord blood can be teased to grow into other types of tissue besides blood. This would open up an entirely new realm of potential treatment through the use of stem cells.

Make no mistake, cord banks are businesses to the core. And just like any other business, there’s always the possibility of a cord bank failing. Which is why we suggest begining your search by checking the company’s experience, the number cord blood units stored, and how many of these cord blood units have been used for transplants.
Of particular interest are the flexible hematopoietic stem cells important in that initial transplant. In certain cases, transplanting these cells might be able to reboot a person’s body and get rid of a disease-related defect. Cord blood transplants are similar to bone marrow transplants. A person with leukemia, for instance, might have his own cancerous blood cells wiped out with chemotherapy and radiation. Healthy, non-cancerous stem cells from a donor can then repopulate the blood.
You’ve just visited the doctor and the good news is that you’re going to have a baby and everything looks good. Thirty years ago, your doctor may have given you a baby book and information about products that sponsors want you to buy for your new addition. Today, along with pretty much the same materials, you’ll be asked to consider saving the blood of your newborn that’s left over in the umbilical cord and placenta after the delivery. Another big decision, and possibly a costly one.

Some researchers suspect that umbilical cord blood contains other cells that may have therapeutic effects beyond the blood. Specialized immune cells may be able to tweak brain function, for instance. Trials around the world are studying umbilical cord blood’s capabilities in a wide range of diseases (see Table 2 here): Cerebral palsy, autism, diabetes and lupus are currently under investigation. The cells are even being tested for an ameliorating role in Alzheimer’s disease and other neurodegenerative conditions.
The “cell recovery rate” is often used to compare processing methods. Expressed as a percentage, the cell recovery rate tells you how many cells are retrieved from the original cord blood collection, once plasma has been removed and red blood cells have been reduced or removed. It is expected that some cells will be lost during processing, and most processing methods have published cell recovery rates between 80%—99%
Current applications for newborn stem cells include treatments for certain cancers and blood, metabolic and immune disorders. Additionally, newborn stem cell preservation has a great potential to benefit the newborn’s immediate family members with stem cell samples preserved in their most pristine state.
Prior to transplanting any type of tissue, a “matching” process must occur to increase the success of the transplant and decrease the likelihood that the transplant will be rejected. The rejection of a transplanted tissue is called “graft versus host disease.” The matching process dates back to the late 1950s when the human leukocyte antigens were discovered. There are two classes of human leukocyte antigens. The first class is located on the surface of almost all of the cells with a nucleus within the body of the cell. The second class of human leukocyte antigens is located on the surface of immune cells. Each of the two classes of antigens has three subgroups, creating six antigens for which matching can occur. Thus, a “6 of 6” matching of the antigens represents a “perfect” match. Beyond the matching process, other factors contribute to the success or failure of a stem cell transplant. These factors include, but are not limited to, the age of both the donor and the patient, the type of disease being treated, and the number of stem cells being transplanted (Moise, 2005).
Just like other blood donations, there is no cost to the donor of cord blood. If you do not choose to store your baby’s blood, please consider donating it. Your donation could make a difference in someone else’s life.

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
When all the processing and testing is complete, the cord blood stem cells are frozen in cryogenic nitrogen freezers at -196° C until they are requested for patient therapy. Public banks are required to complete the entire laboratory processing and freeze the cord blood stem cells within 48 hours of collection. This is to insure the highest level of stem cell viability. The accreditation agencies allow family banks a window of 72 hours.
Initially, cord blood stem cell transplantation using allogeneic umbilical cord blood was performed in relatively small children, because the cell dose per weight of recipient was shown to be important.19,20 However, older children, adolescents, and adults have benefited from unrelated allogeneic umbilical cord blood transplantation.34,55–61 Because of the relationship between cell dose per recipient weight and transplant outcome, the number of cord blood cells needed for marrow reconstitution in older children or young adults is much larger than that needed when cord blood is used for transplantation in small children. Cord blood transplants using multiple cryopreserved units from separate donors have been performed successfully in adults, and the approach is currently under investigation as a strategy to increase the dose of cells for transplantation in a single recipient.62 Cord blood is collected in observance of good obstetric and pediatric practice.45
When parents donate cord blood to a public bank, they are supporting patients around the world who are searching for an unrelated Allogeneic donor. When parents save cord blood in a family bank, they are reserving the options that the baby can use its own stem cells for an Autologous treatment, or an immediate relative (sibling or parents) can use the stem cells for an Allogeneic treatment.
“Processing” refers to separating the important components of the whole cord blood before cryopreservation. There are many methods used to process cord blood that can achieve the same goal: storing the important cells for potential future use. However, it’s important to point out some differences between methods:
To save money, public banks will not even process a cord blood donation unless they know in advance that they are going to keep it. When the collection first arrives at the lab, it is passed through a cell counting machine. Only collections that have at least 900 million nucleated cells are kept. As a result, over 60%-80% of cord blood donations are discarded. The public bank must absorb the expense of the collection kit and delivery charges for discarded blood; typically $100 per unit.
That may sound expensive, but the cost of processing cord blood and storing it in medical freezers for years on end is considerable. Even public cord blood banks say the initial collection, processing, and storage cost them about $1,500 per unit of cord blood.

The stored blood can’t always be used, even if the person develops a disease later on, because if the disease was caused by a genetic mutation, it would also be in the stem cells. Current research says the stored blood may only be useful for 15 years.
