The American Pediatric Association in 2008 recommended that physicians recommend that cord blood be donated instead of saved privately for family families. One of the major proponents for this was Joanne Kurtzberg, who profited from this by getting funding for her public cord blood bank at Duke University. She has since started her own private cord blood bank after doing more research on Cerebral Palsy. Interesting.
While many diseases can be treated with a cord blood transplant, most require stem cells from another donor (allogeneic). Cord blood cells taken from the patient (autologous) typically contain the same defect or precancerous cells that caused the patient to need the transplant in the first place. Most medical professionals believe the chance that cord blood banking will be utilized by the patient or a close relative is relatively low. Estimates range from 1 out of 1,000 to 1 out of 200,000. From these estimates, privately stored cord blood is not likely to be utilized by the average family. The American Academy of Pediatrics has discouraged cord blood banking for self-use, since most diseases requiring stem cell transplants are already present in the cord blood stem cells. Additionally, a recent study published in Pediatrics indicates that few transplants have been performed using privately stored cord blood. From the responses of 93 transplant physicians, in only 50 cases was privately banked blood used. In 9 of these cases the cord blood was transplanted back into the donor patient (autologous transplant). One of the main selling points of private cord blood banks is the possibility of a future autologous transplant.
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.
Banked cord blood is most abundant in white blood cells and stem cells. While a lot of attention is paid to the stem cells, there are approximately 10 times more total nucleated cells (TNCs) than stem cells in any cord blood collection. TNCs are basically white blood cells, or leukocytes; they are the cells of the immune system that protect the body. Despite stem cells comprising one-tenth of most collections, cord blood is still considered a rich source of hematopoietic (he-mah-toe-po-ee-tic) stem cells (HSCs). HSCs are often designated by the marker CD34+. Hematopoietic stem cells can become two categories of cells: myeloid and lymphoid cells. Myeloid cells go on to form your red blood cells, platelets, and other cells of the blood. Lymphoid cells go on to become the B cells and T cells and are the basis for the immune system. Cord blood also contains mesenchymal (meh-sen-ki-mal) stem cells (MSCs), but they are much more abundant in cord tissue, which we will discuss in a minute.
Haematopoietic stem cells (HSCs) can make every type of cell in the blood – red cells, white cells and platelets. They are responsible for maintaining blood production throughout our lives. They have been used for many years in bone marrow transplants to treat blood diseases.
Banking a baby’s blood and stem cells in a cord blood bank is a type of insurance. Ideally, you would not need to access your baby’s stem cells in order to address a medical concern. However, using a cord blood bank can provide peace of mind in knowing that you have a valuable resource if you need it.
Your baby’s cord blood could be a valuable resource for another family. From foundations to non-profit blood banks and medical facilities, there are numerous locations that will collect, process, and use the stem cells from your baby’s cord blood to treat other people.
In addition to the use of cord blood stem cells for transplantation, cord blood stem cells are currently being investigated for use in stem cell therapy. Cord blood stem cells are multipotent and are believed to have greater plasticity (the ability to form into different stem cell types) than adult hematopoietic stem cells found in bone marrow. HSCs are being investigated for use in autoimmune diseases such as diabetes, rheumatoid arthritis, and systemic lupus erythermatosis (SLE) in order to reprogram or reconstitute the immune system. Additionally, research is being conducted on differentiating HSCs into other tissue types such as skeletal and cardiac muscle, liver cells (hepatocytes), and neurons. HSCs are currently being used in gene therapy, due to their self-renewing properties, as a means of delivering genes to repair damaged cells. HSCs are the only cells currently being used in this manner in clinical gene therapy trials.
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.
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.)
“This reanalysis supports several previously expressed opinions that autologous [to use one’s OWN cells] banking of cord blood privately as a biological insurance for the treatment of life-threatening diseases in children and young adults is not clinically justified because the chances of ever using it are remote. The absence of published peer-reviewed evidence raises the serious ethical concern of a failure to inform prospective parents about the lack of future benefit for autologous cord banking … Attempts to justify this [commercial cord blood banking] are based on the success of unrelated public domain cord banking and allogeneic [using someone ELSE’S cells] cord blood transplantation, and not on the use of autologous [the person’s OWN cells] cord transplantation, the efficacy of which remains unproven”.
Of course, this means that expectant parents will have one more choice to make about their child’s health and future. “I certainly don’t think parents should feel guilty if they don’t privately bank their child’s blood,” Dr. Kurtzberg says. The best choice is the one that works for your family.
Like most transplants, the stem cells must be a genetic match with the patients to be accepted by the body’s immune system. It goes without saying that a patient’s own cord blood will be a 100% match. The second highest chance of a genetic match comes from siblings.
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.
Today, many conditions may be treatable with cord blood as part of a stem cell transplant, including various cancers and blood, immune, and metabolic disorders. Preserving these cells now may provide your family potential treatment options in the future.
In Europe, Canada, and Australia use of cord blood is regulated as well. In the United Kingdom the NHS Cord Blood Bank was set up in 1996 to collect, process, store and supply cord blood; it is a public cord blood bank and part of the NHS.
Florida Hospital for Children is conducting an FDA-regulated phase I clinical trial to investigate the use of a child’s stem cells derived from their own cord blood as a treatment for acquired sensorineural hearing loss.
Private cord blood banks allow families to store cord blood stem cells for themselves and their loved ones. They are privately funded, and typically charge a first-year processing fee that ranges from about $1,400 to $2,300, plus annual storage costs of about $115 to $175. (Americord offers cord blood banking for a one-time fee of $3,499, which includes 20 years of storage). The pros and cons of private cord blood banking are listed below.
Cord blood donation doesn’t cost anything for parents. Public cord blood banks pay for everything which includes the collection, testing, and storing of umbilical cord blood. This means that cord blood donation is not possible in every hospital.
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.
Generally, cord blood can only be used to treat children up to 65 lbs. This is because there simply aren’t enough stem cells on average in one unit of cord blood to treat an adult. Through our Cord Blood 2.0 technology, we have been able to collect up to twice as many stem cells as the industry average. Getting more stem cells increases the chance of being able to treat someone later in life.
Cord blood contains mesenchymal stem cells but is much more abundant in hematopoietic stem cells. Cord tissue, on the other hand, contains some hematopoietic stem cells but is much richer in mesenchymal stem cells. Cord tissue, or Wharton’s jelly, is the protective layer that covers the umbilical cord’s vein and other vessels. Its MSCs can become a host of cells including those found in the nervous system, sensory organs, circulatory tissues, skin, bone, cartilage, and more. MSCs are currently undergoing clinical trials for sports injuries, heart and kidney disease, ALS, wound healing and autoimmune disease. As with cord blood, cord tissue is easily collected at the type of birth and holds great potential in regenerative medicine. Learn more about cord tissue banking here.
Up to 180 mL of blood can be taken from an umbilical cord for use in stem cell transplants. Due to the experimental nature of cord blood transplants, such transplants are considered on a case-by-case basis. This blood is collected from the umbilical cord, processed, and cryogenically preserved shortly after the umbilical cord is clamped. This blood can be cryogenically preserved for public or private (family) use. Public registries store cord blood donated for availability to the general public for transplantation. Private registries store cord blood on behalf of families who wish to use this blood for the donor infant, siblings, or other family members. Private cord blood banks charge a collection fee (ranging from $1,000-2,000) and an annual storage fee (approximately $150 per year).
Your baby isn’t the only one who may benefit from having access to preserved newborn stem cells. The cells can potentially be used by siblings and parents, too. In many cord blood treatments, stem cells from a matched family member are preferred.
Banking of stem cells from cord blood began in 1994 with the foundation of the New York Blood Centre Cord Blood Bank. The field of umbilical cord blood storage has matured considerably over the last two decades. We continue to learn more about the long-term effects of cryo-preservation on the cells, which has resulted in increased storage times.
Your baby’s newborn stem cells are transported to our banking facilities by our medical courier partner, and you can receive tracking updates. Each sample is processed and stored with great care at our laboratory in Tucson, Arizona. CBR’s Quality Standard means we test every cord blood sample for specific quality metrics.
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.
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.
Cord blood cannot be used if the donor (baby) contains the same genetic illness as the recipient. Most cord blood banks glaze over this, but it is important to understand that the odds of using cord blood for the same child are much lower than the odds of using them for a sibling.
The Stem Cell Therapeutic and Research Act was passed in 2005, which supports building a public reserve of 150,000 cord blood units from ethnically diverse donors in order to treat more than 90% of patients in need of HSC transplants. Donors from ethnic minority patients are particularly in need due to the greater variation of HLA-types in non-Caucasian ethnicities. Thirty-five percent of cord blood units go to patients of diverse ethnic and racial backgrounds.
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.
Generally not. The reason siblings are more likely to match is because they get half of their HLA markers from each parent. Based on the way parents pass on genes, there is a 25 percent chance that two siblings will be a whole match, a 50 percent chance they will be a half match, and a 25 percent chance that they will not be a match at all. It is very rare for a parent to be a match with their own child, and even more rare for a grandparent to be a match.
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:
While banking cord blood is a new experience for many parents, it is a simple one. After all, most mothers are worried about how the delivery will go and don’t want to also be worried about the details of collecting, processing and cryo-preserving their babies’s cord blood. Thankfully, the healthcare provider and the cord blood bank do most of the work. Here are the steps found in cord blood banking:
The majority of programs that accept cord blood donations require the mother to sign up in advance. In the united States, the current requirement is to sign up by the 34th week of pregnancy. This cannot be over-stressed; time and time again, mothers who want to donate are turned away because they did not inquire about donation until it was too late.
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.
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.
The University of Texas Health Science Center at Houston is conducting a pioneering FDA-regulated phase I/II clinical trial to compare the safety and effectiveness of two forms of stem cell therapy in children diagnosed with cerebral palsy. The randomized, double-blinded, placebo-controlled study aims to compare the safety and efficacy of an intravenous infusion of autologous cord blood stem cells to bone marrow stem cells.
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.
No one knows how stem cells will be used in the future, but researchers hope that they may be used to treat many conditions, like Alzheimer’s, diabetes, heart failure, spinal cord damage, and other conditions.
