The Cord Blood Bank of Arkansas launched operations in 2011, providing both public donation and family banking services. They accept donations from ANY HOSPITAL IN THE STATE OF ARKANSAS. They also accept donations from bordering states so long as the donor is an Arkansas resident.
Fortunately, those odds should improve soon. In 2005, Congress passed the Stem Cell Therapeutic and Research Act, which provides $79 million in federal funding to create a centralized cord-blood registry much like the one that exists for bone marrow. The goal is to expand the existing inventory of 45,000 donated cord-blood units to 150,000.
Within 24 hours of giving birth, your doctor will take a small blood sample. In most cases, the blood sample is sent to the bank along with your child’s cord blood. This helps the storage facility staff when checking the blood for diseases and contamination. Some hospitals may decide to test the mother’s blood for diseases themselves.
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.
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.
In this way, cord blood offers a useful alternative to bone marrow transplants for some patients. It is easier to collect than bone marrow and can be stored frozen until it is needed. It also seems to be less likely than bone marrow to cause immune rejection or complications such as Graft versus Host Disease. This means that cord blood does not need to be as perfectly matched to the patient as bone marrow (though some matching is still necessary).
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.
While the stem cell count is smaller during a cord blood transplant, these cells multiply quickly, and researchers are studying new methods to increase cells naturally. Compared to bone marrow, cord blood cells multiply faster and don’t require an exact match type to complete a successful transplant. Some techniques medical experts are testing to increase the amount of stem cells include:
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.
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.
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.)
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.
In the body, stem cells live in specialized “niches,” microenvironments included stem cell support cells and extracellular matrix. The niche microenvironment regulates the growth and differentiation of stem cells (4–6). Understanding the role of the various “support” cells and the environment of the niche is helpful for in vitro manipulation and maintenance of stem cell populations. For example, a normal atmospheric oxygen concentration of 21% is relatively toxic to stem cells, and growth in “hyoxic” conditions of 2–3% oxygen is preferred (7). Other components of the niche, such as the extracellular matrix and growth and angiogenic factors, play a role in stem cell regulation. Understanding the stem cell microenviornment is rapidly unfolding and is an important topic which, however, is beyond the scope of this article.
Since most banks require mothers to sign up for donation between the 28th and 34th week of pregnancy, families must decide to donate ahead of time. If you are considering a public bank for your child’s cord blood, contact the bank and make sure you still have time.
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.

Be the Match is a nonprofit organization that supports public cord blood banks’ efforts to encourage donations. It maintains the largest public listing of donated cord blood available for transplantation in the United States. The organization has facilitated more than 7,000 unrelated cord blood transplants since the year 2000.
The first cord blood banks were private cord blood banks. In fact, Cryo-Cell is the world’s first private cord blood bank. It wasn’t until later that the government realized the need to preserve cord blood for research and public welfare. As a result, 31 states have adopted a law or have a piece of pending legislation that requires or encourages OBGYNs to educate expectant parents about cord blood banking and many states now have publicly held cord blood banks. As a result, parents have the option of banking their baby’s cord blood privately for the exclusive use of the child and the rest of the family or donating the cord blood to a public bank so that it can be used in research or by any patient who is a match and in need.
Importantly, ESCs are the de facto pluripotent cells for biomedical research. Proponents state that ESCs will enable cell-based therapeutics and biopharmaceutical testing/manufacturing. In contrast, biomedical research conducted using postnatally collected tissues and stem cells has generated less controversy and enjoyed more therapeutic applications to date. This is likely owing to the fact that blood and bone marrow stem cells were found to rescue patients with bone marrow deficiencies about 40 yr ago (8,9). The result of this work produced the national bone marrow registry, which was established in the United States in 1986.
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.
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.
If everyone donated cord blood to public registries for the ‘common good’ this would increase the chances of someone benefiting from a double cord blood transplant. This far outweights the actual probability of the person who donated the sample being able to usefully use it for themself.
On average, the transport time for stem cells from the hospital to CBR’s lab is 19 hours. CBR partners with Quick International, a private medical courier service with 30 years of experience in the transportation of blood and tissue for transplant and research.
We will notify both your doctor and the hospital that you have registered to donate your baby’s cord blood to our program. However, we recommend that you remind the Labor and Delivery staff when you go for your delivery that you want to donate cord blood.
Make sure you meet a few basic guidelines for public banking. Your doctor will give you an advanced blood test after giving birth, but there are a few basic requirements you have to meet before signing up. The requirements are different for each bank, but you can see our basic list of public banking requirements here.
