Pregnant women sometimes have questions or concerns regarding umbilical cord blood donation. Two common questions are: Can their infant’s cord blood be used to benefit MS research? Another question: Is it worthwhile to “bank” their infant’s umbilical cord blood for the benefit of a family member who might need the umbilical stem cells for future treatment of their MS?
Excitement about cord tissue’s potential to help conditions affecting cartilage, muscle and nerve cells continues to grow.19 Researchers are focusing on a wide range of potential treatment areas, including Parkinson’s disease, Alzheimer’s, liver fibrosis, lung cancer, and sports injuries. Since 2007 there have been 150 clinical trials using cord tissue stem cells.
Yes, if you have any sick children who could benefit from umbilical cord blood. Public banks such as Carolinas Cord Bank at Duke University and private banks such as FamilyCord in Los Angeles offer programs in which the bank will assist with cord blood processing and storage if your baby has a biological sibling with certain diseases. FamilyCord will provide free cord blood storage for one year. See a list of banks with these programs at parentsguidecordblood.org/help.php.
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.
Beyond these blood-related disorders, the therapeutic potential of umbilical cord blood stem cells is unclear. No therapies for non-blood-related diseases have yet been developed using HSCs from either cord blood or adult bone marrow. There have been several reports suggesting that umbilical cord blood contains other types of stem cells that are able to produce cells from other tissues, such as nerve cells. Some other reports claim that umbilical cord blood contains embryonic stem cell-like cells. However, these findings are highly controversial among scientists and are not widely accepted.
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.
The stem cells used in BMT come from the liquid center of the bone, called the marrow. In general, the procedure for obtaining bone marrow, which is called “harvesting,” is similar for all three types of BMTs (autologous, syngeneic, and allogeneic). The donor is given either general anesthesia, which puts the person to sleep during the procedure, or regional anesthesia, which causes loss of feeling below the waist. Needles are inserted through the skin over the pelvic (hip) bone or, in rare cases, the sternum (breastbone), and into the bone marrow to draw the marrow out of the bone. Harvesting the marrow takes about an hour.
The immune system has a way to identify foreign cells; it’s what allows the body to defend itself. So although transplants were proving successful after the first in 1956, they were limited to twins because their shared genetic makeup made them 100 percent compatible. This took a turn in 1958, when scientists discovered a protein present on the surface of almost all cells that lets the body know if the cell is one of its own cells or a foreign cell. In 1973, we finally learned enough about these compatibility markers (called human leukocyte antigens or HLAs) to perform the first unrelated bone marrow transplant.
Through these two means, we are always producing more cells. In fact, much of your body is in a state of constant renewal because many cells can live for only certain periods of time. The lifespan for a cell in the stomach lining is about two days. Red blood cells, about four months. Nerve and brain cells are supposed to live forever. This is why these cells rarely regenerate and take a long time if they do.
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.
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.
Tissue 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.)
Further advancements were made in 1978, when stem cells were discovered in cord blood and in 1988, when cord blood stem cells were first used in a transplant. Stem cells extracted from the umbilical cord blood or tissue have since been shown to be more advantageous than those extracted from other sources such as bone marrow. In many ways, this is because stem cells from the umbilical cord can be considered naïve and immature compared to stem cells from other sources. Cord stem cells haven’t been exposed to disease or environmental pollutants, and they are more accepting of foreign cells. In this case, inexperience makes them stronger.
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.
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.
Your body has many different types of cells (more than 200 to be more exact) each geared towards specific functions. You have skin cells and blood cells, and you have bone cells and brain cells. All your organs comprise specific cells, too, from kidney cells to heart cells.
Clinical trials that include BMT and PBSCT are a treatment option for some patients. Information about ongoing clinical trials is available from NCI’s CIS at 1–800–422–6237 (1–800–4–CANCER) or on NCI’s website.
Taking time to consider helping another person when you are already busy planning for the birth of your child is greatly appreciated. A gift of cord blood may someday give someone a second chance at life.
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.
Because only a small amount of bone marrow is removed, donating usually does not pose any significant problems for the donor. The most serious risk associated with donating bone marrow involves the use of anesthesia during the procedure.
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.

Since 1989, umbilical cord blood has been used successfully to treat children with leukaemia, anaemias and other blood diseases. Researchers are now looking at ways of increasing the number of haematopoietic stem cells that can be obtained from cord blood, so that they can be used to treat adults routinely too.
All cord blood is screened and tested. Whether you use a public or private bank, you’ll still need to be tested for various infections (such as hepatitis and HIV). If tests come back positive for disease or infection, you will not be able to store your cord blood.
