As noted earlier, with better matching, there is a greater chance of success and less risk of graft-versus-host disease (GvHD) in any stem cell transplant. With cord blood, the baby’s own cells are always a perfect match and share little risk. When using cord blood across identical twins, there is also a very low chance of GvHD although mutations and biological changes caused by epigenetic factors can occur. Other blood-related family members have a 35%–45% chance of GvHD, and unrelated persons have a 60%–80% chance of suffering from GvHD.
While most people have a small amount of stem cells in their bloodstream, donors produce more stem cells after taking growth factor hormones. Doctors give these medications a few days before stem cell harvesting, which makes the bone marrow push more cells into the bloodstream.
HSCs can become any type of blood cell or cellular blood component inside the body, including white blood cells and red blood cells. These cells are found in umbilical cord blood and are multipotent, which means they can develop into more than one cell type.
Stem cells from cord blood can be used for the newborn, their siblings, and potetinally other relatives. Patients with genetic disorders like cystic fibrosis, cannot use their own cord blood and will need stem cells from a sibling’s cord blood. In the case of leukemia or other blood disorders, a child can use either their own cord blood or their sibling’s for treatment.
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.
Meet Dylan. Diagnosed with leukemia at just 8 weeks old, he received a life-saving cord blood transplant at 6 months old. Today, Dylan is growing up strong, going to school, travelling with his family and just having fun being a kid!
The proteins stem from three HLA genes, and you inherit one HLA from each parent, or half your HLA markers from your mother and half from your father. This gives siblings a 25 percent chance of being a perfect match, a 50 percent chance of being a partial match and another one-in-four chance of not being a match at all. Unfortunately, about seven out 10 patients who need a transplant don’t have a suitable donor in their family. They can either rely on their own stem cells, isolated before treatment or previously preserved, or try to find a match through a public donor.
There is little doubt that scientists believe umbilical cord blood stem cells hold promise for the future. Cord blood stem cells are already used to treat blood disorders such as aplastic anemia, and research is underway to determine if they can treat other more common conditions like type 1 diabetes. But many experts question whether many companies’s marketing materials confuse or even mislead parents about the usefulness of private banking.

Public cord blood banks store cord blood for allogenic transplants. They do not charge to store cord blood. The stem cells in the donated cord blood can be used by anyone who matches. Some public banks will store cord blood for directed donation if you have a family member who has a disease that could potentially be treated with stem cells.
Stem cells are powerful, adaptable cells that can be used to promote healing and reverse damage. Stem cells are found in various places within the human body, but the purest stem cells are found in the umbilical cord.
Fill out medical history sheets. The bank will ask you and your doctor to fill out medical forms that cover your infant, adolescent, and adult health. This helps the bank understand your general medical health to see if your child’s cord blood is useable in treatment. Overall, public banks usually accept healthy mothers without a history of severe inherited conditions.
iPS cells are artificially-made pluripotent stem cells. This technique allows medical staff to create additional pluripotent cells, which will increase treatment options for patients using stem cell therapy in the near future.
Tissue is typed and listed on the registry of the C.W. Bill Young Cell Transplantation Program, also called the Be The Match Registry®. (The registry is a listing of potential marrow donors and donated cord blood units. When a patient needs a transplant, the registry is searched to find a matching marrow donor or cord blood unit.) It’s frozen in a liquid nitrogen freezer and stored, so if the unit is selected as a match for a patient needing a transplant, it will be available.

For example, in the UK the NHS Cord Blood Bank has been collecting and banking altruistically donated umbilical cord blood since 1996. The cord blood in public banks like this is stored indefinitely for possible transplant, and is available for any patient that needs this special tissue type. There is no charge to the donor but the blood is not stored specifically for that person or their family.
Tracey Dones of Hicksville, N.Y., paid to bank her son Anthony’s cord blood. But four months after he was born, Anthony was diagnosed with osteopetrosis, a rare disease that causes the body to produce excess bone, leads to blindness, and can be fatal if left untreated.
* Annual storage fees will be charged automatically to the credit/debit card on file, on or around your baby’s birthday, unless you’ve chosen a prepay option and are subject to change until they are paid.
The range of diseases that doctors can treat with cord blood is vast. More than 80 diseases are currently known to respond to cord blood stem cells transplants and, as more are studied and tested, that number is sure to grow.
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 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.
Let the birthing staff know you’re donating cord blood. They will either have a kit sent to them from the private bank, or have the necessary equipment on location. Your bank should have already spoken with your doctor and the birthing staff on proper cord blood collections procedures, but you want to make sure everyone there knows to collect the umbilical cord after birth.
Stem cells from cord blood can be given to more people than those from bone marrow. More matches are possible when a cord blood transplant is used than when a bone marrow transplant is used. In addition, the stem cells in cord blood are less likely to cause rejection than those in bone marrow.
It depends on who you ask. Although commercial cord blood banks often bill their services as “biological insurance” against future diseases, the blood doesn’t often get used. One study says the chance that a child will use their cord blood over their lifetime is between 1 in 400 and 1 in 200,000.
The therapuetic potential of cord blood continues to grow. Over the last few years cord blood use has expanded into an area known as regenerative medicine. Regenerative medicine is the science of living cells being used to potentially regenerate or facilitate the repair of cells damaged by disease, genetics, injury or simply aging. Research is underway with the hope that cord blood stem cells may prove beneficial in young patients facing life-changing medical conditions once thought untreatable – such as autism and cerebral palsy.
Scientists first found ways to use stem cells in bone marrow, and following this discovery, the first stem cell transplant was performed in 1956 via bone marrow between identical twins. It resulted in the complete remission of the one twin’s leukemia.
Your cells didn’t start out knowing how to come together to form your bones, heart or blood; they begun with more of a blank slate. These completely undifferentiated cells can be found during gestation, or the time the baby is in the womb, and are called embryonic stem cells. These early stage stem cells are master cells that have the potential to become any type of cell in the body.
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.
CBR is committed to advancing the science of newborn stem cells. We’ve awarded a grant to the Cord Blood Association, to help fund a multi-center clinical trial researching the use of cord blood for children with autism and cerebral palsy.
“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”.
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.
Your adult cells have one disadvantage to cord blood cells – they cannot change their cell type. When stem cells from cord blood and tissue are transplanted, they adjust to fit the individual patient and replace damaged cells. Adult stem cells are also older, which means they have been exposed to disease, and may damage patients after the transplant. Compared to cord blood cells, adult cells have a higher chance for graft-versus-host disease.
Several research teams have reported studies in animals suggesting that cord blood can repair tissues other than blood, in diseases ranging from heart attacks to strokes. These findings are controversial: scientists often cannot reproduce such results and it is not clear HOW cord blood may be having such effects. When beneficial effects are observed they may be very slight and not significant enough to be useful for developing treatments. If there are positive effects, they might be explained not by cord blood cells making nerve or heart cells, but by the cells in the cord blood releasing substances that help the body repair damage.
Most cells can make copies only of themselves. For example, a skin cell only can make another skin cell. Hematopoietic stem cells, however, can mature into different types of blood cells in the body. Hematopoietic stem cells also are found in blood and bone marrow in adults and children.
Families have the additional option of storing a section of the umbilical cord, which is rich in unique and powerful stem cells that may help repair and heal the body in different ways than stem cells derived from cord blood.
In an allogenic transplant, another person’s stem cells are used to treat a child’s disease. This kind of transplant is more likely to be done than an autologous transplant. In an allogenic transplant, the donor can be a relative or be unrelated to the child. For an allogenic transplant to work, there has to be a good match between donor and recipient. A donor is a good match when certain things about his or her cells and the recipient’s cells are alike. If the match is not good, the recipient’s immune system may reject the donated cells. If the cells are rejected, the transplant does not work.
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.
