A major limitation of cord blood transplantation is that the blood obtained from a single umbilical cord does not contain as many haematopoeitic stem cells as a bone marrow donation. Scientists believe this is the main reason that treating adult patients with cord blood is so difficult: adults are larger and need more HSCs than children. A transplant containing too few HSCs may fail or could lead to slow formation of new blood in the body in the early days after transplantation. This serious complication has been partially overcome by transplanting blood from two umbilical cords into larger children and adults. Results of clinical trials into double cord blood transplants (in place of bone marrow transplants) have shown the technique to be very successful. Some researchers have also tried to increase the total number of HSCs obtained from each umbilical cord by collecting additional blood from the placenta.
There are over 130 public cord blood banks in 35 countries. They are regulated by Governments and adhere to internationally agreed standards regarding safety, sample quality and ethical issues. In the UK, several NHS facilities within the National Blood Service harvest and store altruistically donated umbilical cord blood. Trained staff, working separately from those providing care to the mother and newborn child, collect the cord blood. The mother may consent to donate the blood for research and/or clinical use and the cord blood bank will make the blood available for use as appropriate.
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?
CBR created the world’s only collection device designed specifically for cord blood stem cells. CBR has the highest average published cell recovery rate in the industry – 99% – resulting in the capture of 20% more of the most important cells than other common processing methods.
Private companies offer to store cord blood for anyone who wants it done, whether or not there is any medical reason known to do so at the time. The fee for private storage varies, but averages about $1,500 up front and $100 per year for storage. When there is no one in the family who needs a transplant, private storage of a newborn’s cord blood is done for a purely speculative purpose that some companies have termed “biological insurance.”
One oft cited argument against cord blood banking is that it is not known how long these cells can remain viable in storage. While it is not known if cells taken from an individual as an infant will be beneficial to them as an adult, units stored for up to 10 years have been transplanted successfully. This indicates that there is no reason to suggest serious deterioration in the quality of cord blood units stored for longer periods of time.
Umbilical cord blood is the blood left over in the placenta and in the umbilical cord after the birth of the baby. The cord blood is composed of all the elements found in whole blood. It contains red blood cells, white blood cells, plasma, platelets and is also rich in hematopoietic stem cells. There are several methods for collecting cord blood. The method most commonly used in clinical practice is the “closed technique”, which is similar to standard blood collection techniques. With this method, the technician cannulates the vein of the severed umbilical cord using a needle that is connected to a blood bag, and cord blood flows through the needle into the bag. On average, the closed technique enables collection of about 75 ml of cord blood.
To prevent graft-versus-host disease and help ensure engraftment, the stem cells being transfused need to match the cells of the patient completely or to a certain degree (depending on what is being treated). Cord blood taken from a baby’s umbilical cord is always a perfect match for the baby. In addition, immediate family members are more likely to also be a match for the banked cord blood. Siblings have a 25 percent chance of being a perfect match and a 50 percent chance of being a partial match. Parents, who each provide half the markers used in matching, have a 100% chance of being a partial match. Even aunts, uncles, grandparents and other extended family members have a higher probability of being a match and could possibly benefit from the banked cord blood.

Blood in the umbilical cord and placenta is rich with blood-forming stem cells that can help save the lives of patients with diseases and disorders such as leukemia, lymphoma and aplastic anemia. With your consent, Canadian Blood Services can collect cord blood when you deliver your baby for Canadian Blood Services’ Cord Blood Bank—to be used by anyone who needs stem cell treatment.
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.
If you’re reading this, you may likely also agree that the cord blood should be saved, leaving only a decision whether to donate your baby’s cord blood to a public bank or to preserve it for your baby’s and other family members’ potential future use. Parents should be fully informed of how each options compares prior to making a final decision.

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.
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. Anyway, the excitement over the embryonic cells comes from…
The Celebration Stem Cell Centre (CSCC), offers both public donation and private “family banking” of umbilical cord blood. All cord blood collections are processed according to the highest standards in the industry in a new, state-of-the art facility located in Gilbert, Arizona. The public cord blood donation program is funded by the private “family banking” program and private philanthropy.

While cord-blood companies herald the possible future treatments of many adult diseases with stem cells, they rarely mention a key issue. Researchers have greater hopes for the potential of embryonic stem cells, which are thought to have the ability to develop into many different types of cells. It is not known whether the stem cells in cord blood have that ability; until recently, it was thought that they (like those in bone marrow) could only regenerate blood and immune cells.
Cord blood (short for umbilical cord blood) is the blood that remains in the umbilical cord and placenta post-delivery. At or near term, there is a maternal–fetal transfer of cells to boost the immune systems of both the mother and baby in preparation for labor. This makes cord blood at the time of delivery a rich source of stem cells and other cells of the immune system. Cord blood banking is the process of collecting the cord blood and extracting and cryogenically freezing its stem cells and other cells of the immune system for potential future medical use.
There is no significant opposition in the medical community to the public banking of cord blood. The donation of cord blood to public banks has generally been encouraged by the medical profession. The American Academy of Pediatrics encourages the public donation of cord blood with appropriate genetic and infectious disease testing, although they caution that parents should be notified that they will receive the results of this testing. They also recommend that parents be informed that publicly banked cord blood may not be available for future private use.
Pro: It gives you that peace of mind that if anything did happen to your child, the doctors would have access to their blood. This could potentially be a great benefit, and you would have no idea what would have happened if it weren’t for this blood.
At present, the odds of undergoing any stem cell transplant by age 70 stands at one in 217, but with the continued advancement of cord blood and related stem and immune cell research, the likelihood of utilizing the preserved cord blood for disease treatment will continue to grow.

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.
