Some controversial studies suggest that cord blood can help treat diseases other than blood diseases, but often these results cannot be reproduced. Researchers are actively investigating if cord blood might be used to treat various other diseases.
Checked to make sure it has enough blood-forming cells for a transplant. (If there are too few cells, the cord blood unit may be used for research to improve the transplant process for future patients or to investigate new therapies using cord blood, or discarded.)
There are some hospitals that have dedicated collections staff who can process mothers at the last minute when they arrive to deliver the baby. However, in the United States that is the exception to the rule.
The next step at either a public or family bank is to process the cord blood to separate the blood component holding stem cells. The final product has a volume of 25 milliliters and includes a cryoprotectant which prevents the cells from bursting when frozen. Typical cost, $250 to $300 per unit.
Umbilical cord blood is blood that remains in the placenta and in the attached umbilical cord after childbirth. Cord blood is collected because it contains stem cells, which can be used to treat hematopoietic and genetic disorders.
Cord blood is currently approved by the FDA for the treatment for nearly 80 diseases, and cord blood treatments have been performed more than 35,000 times around the globe to treat cancers (including lymphoma and leukemia), anemias, inherited metabolic disorders and some solid tumors and orthopedic repair. Researchers are also exploring how cord blood has the ability to cross the blood–brain barrier and differentiate into neurons and other brain cells, which may be instrumental in treating conditions that have been untreatable up to this point. The most exciting of these are autism, cerebral palsy and Alzheimer’s.
There are several cord blood banks that are accredited by the American Association of Blood Banks. Most offer information on cord blood banking and provide private cord blood banking services. With a little research, you should be able to locate a credible cord blood bank online.
When Tracey and Victor Dones’s 4-month-old son was diagnosed with osteopetrosis, a potentially fatal disorder that affects bone formation, the panic-stricken couple was relieved to hear that a stem-cell transplant could save his life. “We’d paid to store Anthony’s umbilical-cord blood in a private bank in case he ever needed it — and I thought we were so smart for having had the foresight to do that,” says Tracey.
Cord blood is used to treat children with cancerous blood disorders such as leukaemia, or genetic blood diseases like Fanconi anaemia. The cord blood is transplanted into the patient, where the HSCs can make new, healthy blood cells to replace those damaged by the patient’s disease or by a medical treatment such as chemotherapy for cancer.
The parents who make the decision to store their baby’s cord blood and cord tissue are thinking ahead, wanting to do right from the start (even before the start), and taking steps to do whatever they can to protect their baby down the road. Today, many conscientious parents are also considering delayed cord clamping (DCC), a practice in which the umbilical cord is not clamped immediately but rather after it continues to pulse for an average of 30 seconds to 180 seconds. Many parents don’t realize that they can delay the clamping of the cord and still bank their baby’s cord blood. As noted early, our premium processing method, PrepaCyte-CB, is able to capture more immune system cells and reduce the greatest number of red blood cell contaminants. This makes it go hand in hand with delayed cord clamping because it is not as affected by volume, effectively making up for the smaller quantity with a superior quality. You can read more about delayed cord clamping vs. cord blood banking here.
Cord Blood Registry is headquartered in South San Francisco, California. CBR owns their 80,000 square foot laboratory located in Tucson, Arizona. CBR’s laboratory processes cord blood collections seven days a week, 365 days a year. The state-of-the-art facility has the capacity to store the stem cell samples of five million newborns.
Though uses of cord blood beyond blood and immunological disorders is speculative, some research has been done in other areas. Any such potential beyond blood and immunological uses is limited by the fact that cord cells are hematopoietic stem cells (which can differentiate only into blood cells), and not pluripotent stem cells (such as embryonic stem cells, which can differentiate into any type of tissue). Cord blood has been studied as a treatment for diabetes. However, apart from blood disorders, the use of cord blood for other diseases is not in routine clinical use and remains a major challenge for the stem cell community.
There is no cost associated with public cord blood banking, but you do give up your rights to your baby’s stem cells at the time of donation. The public cord blood bank owns the donation. If your child or another family member needs a transplant in the future, there is no guarantee you would have access to your baby’s cord blood.
Cost to Donate Client pays a one-time processing fee and annual storage fees. There is no cost for donating, but there is a cost for retreiving from a public bank. One-time processing fee and annual storage fees No cost for donating, but high cost for public bank retrival
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
Today, cord blood stem cells have been used in more than 35,000 transplants worldwide to regenerate healthy blood and immune systems, like in a bone marrow transplant. 1* Find out which conditions have been treated here.
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. Read more about cord blood as a regenerative medicine here.
As cord blood is inter-related to cord blood banking, it is often a catch-all term used for the various cells that are stored. It may be surprising for some parents to learn that stored cord blood contains little of what people think of as “blood,” as the red blood cells (RBCs) can actually be detrimental to a cord blood treatment. (As we’ll discuss later, one of the chief goals of cord blood processing is to greatly reduce the volume of red blood cells in any cord blood collection.)
Cord blood has an abundance of stem cells and immune system cells, and the medical uses of these cells has been expanding at a rapid pace. As these cells help the body re-generate tissues and systems, cord blood is often referred to as a regenerative medicine.
If you make a donation to a public cord blood bank, you can’t reserve it for your family, so it may not be available for your future use. Both the American Academy of Pediatrics (AAP) and American Medical Association (AMA) recommend public cord blood banking over private cord blood banking. Here’s why:
Not surprisingly, this emotional pitch is working — especially because the seemingly unlimited potential of stem cells has dominated the news in recent years. From 2003 to 2004, for example, the number of couples opting to use a private bank increased by 55 percent to 271,000. The three biggest companies — who have the majority of the approximately $250 million market — are vying for business.
Blood from the umbilical cord and placenta is put into a sterile bag. (The blood is put into the bag either before or after the placenta is delivered, depending upon the procedure of the cord blood bank.)
There has been considerable debate about the ethical and practical implications of commercial versus public banking. The main arguments against commercial banking have to do with questions about how likely it is that the cord blood will be used by an individual child, a sibling or a family member; the existence of several well-established alternatives to cord blood transplantation and the lack of scientific evidence that cord blood may be used to treat non-blood diseases (such as diabetes and Parkinson’s disease). In some cases patients may not be able to receive their own cord blood, as the cells may already contain the genetic changes that predispose them to disease.
As your baby’s birth approaches, think about making a cord blood donation. You have the power to Give Life to patients like Jessica. Because two babies’ families gave life through cord blood donation, she can watch her own children grow up.
As the research into umbilical cord blood and it’s therapeutic use for blood diseases has grown, so has the question as to whether people should privately store the cord blood of their offspring for future use. A recent paper on this issue by Mahendra Rao and colleagues advocates the practice of cord blood banking (for treatment of blood diseases) but in the context of public cord blood banks rather than a private cord blood banks. Any adult needing treated would need at least two cord blood samples that are immune compatible. So one sample will not be sufficient. A child might only need one cord blood sample but in the case of childhood leukaemia there is a risk that pre-leukemic cells are present in cord blood sample – and so the child could not use their own cells for therapy.
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.
