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.
It’s hard to ignore the ads for cord blood banks, offering a lifetime of protection for your children. If you’re an expectant mom, there’s information coming at you constantly from your doctor’s office, magazines, online, and perhaps even your yoga class.
There are a number of different processing methods out there for a cord blood bank to use, and the processing method can ultimately affect the purity of the final product, which we’ll explain in a minute. Once the stem and immune system cells have been isolated and extracted from the plasma and red blood cell, they are mixed with a cryo-protectant and stored in a cryo-bag. We overwrap our bags for added protection and use a technique called “controlled-rate freezing” to prepare the cells for long-term storage. The overwrapped cryo-bag is housed in a protective metal cassette and placed in vapor-phase liquid nitrogen freezer for long-term preservation.
The European Group on Ethics in Science and New Technologies (EGE) has also adopted a position on the ethical aspects of umbilical cord blood banking. The EGE is of the opinion that “support for public cord blood banks for allogeneic transplantations should be increased and long term functioning should be assured.” They further stated that “the legitimacy of commercial cord blood banks for autologous use should be questioned as they sell a service which has presently no real use regarding therapeutic options.”
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
Tracey said she felt lucky since she banked Anthony’s cord blood with a private company. And Osteopetrosis is one of 80 diseases listed by many cord blood companies in their marketing material as treatable with stem cells.
Stem cells are injected into the veins during a peripheral blood transplant, and naturally work their way to the bone marrow. Once there, the new cells start increasing healthy blood count. Compared to bone marrow transplants, cells from peripheral blood are usually faster, creating new blood cells within two weeks.
Along with cord blood, Wharton’s jelly and the cord lining have been explored as sources for mesenchymal stem cells (MSC), and as of 2015 had been studied in vitro, in animal models, and in early stage clinical trials for cardiovascular diseases, as well as neurological deficits, liver diseases, immune system diseases, diabetes, lung injury, kidney injury, and leukemia.
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.
As noted, there are different ways to process cord blood, and although the type of processing method doesn’t always enter the conversation on cord blood banking, it is a big part of the purity of any cord blood collection. Red blood cells can have a negative impact on a cord blood transfusion. In addition, there is a certain number of stem cells that need to be present in order for the cord blood to be effective in disease treatment. Each processing method has the ability to better reduce the number of RBCs and capture more stem cells. Some processing methods like AutoXpress and Sepax are automated to ensure a level of consistency across all collections. HES is preferred by some banks because it was the original processing method used by most banks and it has a proven track record. You can read more about the different cord blood processing methods here.
There was a time before the 1990s when the umbilical cord and its blood were considered medical waste. Today, parents bank or store their baby’s umbilical cord blood because the stem cells it contains are currently utilized or show promise in the treatment of life-threatening and debilitating diseases.
The American Academy of Pediatrics supports efforts to provide information about the potential benefits and limitations of cord blood banking and transplantation so that parents can make an informed decision. In addition, the American College of Obstetricians and Gynecologists recommends that if a patient requests information on umbilical cord blood banking, balanced information should be given. Cord blood education is also supported by legislators at the federal and state levels. In 2005, the National Academy of Sciences published an Institute of Medicine (IoM) report titled “Establishing a National Cord Blood Stem Cell Bank Program”.
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.
Private cord blood banking can benefit those with a strong family history of certain diseases that harm the blood and immune system, such as leukemia and some cancers, sickle-cell anemia, and some metabolic disorders. Parents who already have a child (in a household with biological siblings) who is sick with one of these diseases have the greatest chance of finding a match with their baby’s cord blood. Parents who have a family history of autism, Alzheimer’s, and type 1 diabetes can benefit from cord blood. Although these diseases aren’t currently treated with umbilical cord steam cells, researchers are exploring ways to treat them (and many more) with cord blood.
Cord blood is one of three sources of blood-regenerating cells used in stem cell transplantation; the other two sources are bone marrow and peripheral blood stem cells. Stem cells have ability to transform themselves into different types of cells that help replace or heal impaired cells such as bone, nerve and blood cells.

The baby’s cord blood will be processed and stored in a laboratory facility, often referred to as a blood bank. The cord blood should be processed and stored in a facility that is accredited by the American Association of Blood Banks (AABB) for the purpose of handling stem cells.
Umbilical cord blood is useful for research. For example, researchers are investigating ways to grow and multiply haematopoietic (blood) stem cells from cord blood so that they can be used in more types of treatments and for adult patients as well as children. Cord blood can also be donated altruistically for clinical use. Since 1989, umbilical cord blood transplants have been used to treat children who suffer from leukaemia, anaemias and other blood diseases.
Genes: Segments of DNA that contain instructions for the development of a person’s physical traits and control of the processes in the body. They are the basic units of heredity and can be passed down from parent to offspring.
If a sibling of a child whose cord blood you banked needs a transplant, then your chances of a match will be far higher than turning to the public. However, the safest bet is to bank the cord blood of all your children, safeguarding them against a number of diseases and ensuring a genetic match if necessary.
The biggest advantage for cord blood is the “immaturity” of the cells, which means transplants do not require an exact match. For bone marrow and peripheral blood transplants, donors need to match the patient’s cellular structure. However, cord blood cells can adapt to a wide variety of patients, and don’t require donor matching. Chances for graft-versus-host disease are also much lower for cord blood transplants.
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.
CBR uses the AutoExpress automated processing method. AutoExpress (AXP) reduces the chance of human error and provides consistent results in the reduction of certain blood components. It also provides quick and accurate data tracking. Cord Blood Registry is the only cord blood bank to have adopted the AXP processing method.
Stem cells can be used in treatments for many different types of diseases. One of the main places young stem cells are found is in cord blood, which can be stored at birth and saved for future use if needed. Stem cells are also found in other places in the human body, including blood and bone marrow.
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.
Mothers and families can donate blood from their child’s umbilical cord, which contains valuable stem cells used in the treatment of over 80 diseases. There are over half a million donated cord blood units around the world, with thousands more added every year.
This and all other stem cell therapies since involve introducing new stem cells into the area to encourage the healing process. Often, the stem cell will create a particular type of cell simply because it is in proximity to other cells of that type. Unfortunately, researchers still had a ways to go before they could use stem cells from unrelated persons.
Another type of cell that can also be collected from umbilical cord blood are mesenchymal stromal cells. These cells can grown into bone, cartilage and other types of tissues and are being used in many research studies to see if patients could benefit from these cells too.
During the harvesting procedure, doctors use a catheter to draw out blood. The blood moves through a machine, which separates stem cells and allows these cells to be put into storage. This process takes a few hours, and may be repeated over several days in order for doctors to get enough stem cells.
Each year, thousands of people are diagnosed with leukemia, lymphoma, or certain immune system or genetic metabolic disorder. Many of these patients need an umbilical cord blood or bone marrow transplant (also called a BMT). Because the qualities that make a suitable match for bone marrow or umbilical cord blood are inherited, a match from a sibling or other family member is often checked first. However, 70 percent of patients will not find a matching donor in their family. For these patients, a transplant of bone marrow or cord blood from an unrelated donor may be their only transplant option.
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.
If you’re looking to attain cord blood from a public bank, be aware that matched cord blood, as with bone marrow, can be difficult to obtain through a public cord blood bank. Once a match is ascertained, it may take valuable weeks, even months, to retrieve the match, and the cost of acquiring the cord blood from a public bank can be upwards of $40,000. When the newborn’s umbilical cord blood is banked privately, they can be retrieved quickly, and since the parents own the cord blood, banks can perform the retrieval free of charge.
