cord blood testing | what are stem cells cord blood

The blood collected from the cord is, in fact, the same blood your baby receives from the placenta. The blood itself is not ‘from the cord’ but collected from that area. This blood is rich in stem cells, which can grow into blood vessels, organs, and tissues.
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.)
In addition to the stem cells, researchers are discovering specific uses for the other types of cells in the treatment of certain conditions. Cord blood Treg cells hold potential for preventing graft-versus-host disease in stem cell transplantations and ameliorating the effects of autoimmune diseases such as diabetes, rheumatoid arthritis and multiple sclerosis. Cord blood natural killer cells also hold future potential. These cells have been programmed to target specific cancers and tumors in clinical trials. This could make them exceptionally strong candidates for chronic or treatment-resistant cases of cancer.
Another way scientists are working with stem cells is through expansion technologies that spur replication of the cord blood stem cells. If proven effective and approved by the U.S. Food and Drug Administration, these expansion technologies will allow scientists to culture many stem cells from a small sample. This could provide doctors and researchers with enough stem cells to treat multiple family members with one cord blood collection or provide the baby with multiple treatments over time. To better prepare for the day when these expansion technologies are more easily accessible, some cord blood banks have begun to separate their cord blood collections into separate compartments, which can easily be detached from the rest of the collection and used independently.

All families should decide what they want to do with their cord blood well before delivery and make the arrangements accordingly. Because the issue is complex and the decision is a personal one—it’s best to speak with your doctor about what’s right for your family.
Hematopoietic stem cells can be used to treat more than 70 types of diseases, including diseases of the immune system, genetic disorders, neurologic disorders, and some forms of cancer, including leukemia and lymphoma. For some of these diseases, stem cells are the primary treatment. For others, treatment with stem cells may be used when other treatments have not worked or in experimental research programs.
The American Congress of Obstetricians and Gynecologists and the American Academy of Pediatrics don’t recommend routine cord blood storage. The groups say private banks should only be used when there’s a sibling with a medical condition who could benefit from the stem cells. Families are encouraged to donate stem cells to a public bank to help others.
Both public and family cord blood banks must register with the US Food and Drug Administration (FDA), and since Oct. 2011 public banks also need to apply for an FDA license. All cord blood banks are required by federal law to test the blood of the mother for infectious diseases. At public banks the screening is usually more extensive, similar to the tests performed when you donate blood. The typical expense to a public bank is $150 per unit.
However, most cord banks state one of the key factors in successful cord blood treatment is the volume of blood which is infused with stem cells: the greater the cord blood volume, the greater the chance of a successful outcome for the treatment.
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.

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.
Stem cells in the cord blood, cord tissue, and placenta tissue are genetically unique to your baby and family. They can be used to treat various medical problems for your child, his or her siblings, and other family members.

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.
The Medical Letter On Drugs and Therapeutics also recently addressed aspects of public and private cord blood banks, asking the question: “Does Private Banking Make Sense?” After citing various statistics on the actual uses of privately stored cord blood, they concluded that: “At the present time, private storage of umbilical cord blood is unlikely to be worthwhile. Parents should be encouraged to contribute, when they can, to public cord blood banks instead.” [Access The Medical Letter at www.medicalletter.org].
The American Academy of Pediatrics (AAP) recommends families choose to donate their cord blood to public banks in most cases. Private banking should be considered for family use where there is a full sibling in the family with a condition that could potentially benefit from a transplant as siblings have a 25% chance of being a match.
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.
You can choose to donate your baby’s cord blood to a public bank or have it stored in a private bank just for your family. Some hospitals and medical centers are affiliated with public banks — you can check to see about whether this applies to the hospital where you’re planning to give birth.
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 collection of cord blood takes place after the baby has been delivered, so there is no risk to either the mother or baby. The delivery process is not changed or modified because of the cord blood collection. The umbilical cord is clamped, cut and separated from the baby. The baby is then placed in the mother’s arms or taken to a warmer. Only then will your physician or midwife collect the cord blood. The blood from the umbilical cord drains into a standard blood donor collection bag by gravity.

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.
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.
Cord blood is the blood that remains in the umbilical cord and placenta following birth. This blood is usually discarded. However, cord blood banking utilizes facilities to store and preserve a baby’s cord blood. If you are considering storing your baby’s cord blood, make sure to use a cord blood bank accredited by the American Association of Blood Banks (AABB), like Viacord.
Your own cord blood will always be accessible. This applies only if you pay to store your cord blood at a private bank. The blood is reserved for your own family; nobody else can access or use it, and it will never be allotted to another family or be donated to research. If you donate your cord blood to a public bank, on the other hand, anyone who needs compatible cord blood can have it; there’s no guarantee that it will be available if and when your family needs it.
“One of the biggest concerns families have about publicly banking cord blood is: Will it be available to them, if needed? The answer is a little complicated,” Dr. Aghajanian says. “Cord blood donated to a public bank can be pulled for a family of origin.” As long as it is still available, of course.
Currently, cord blood can only treat blood and immune diseases. There is research being done into other ways of using cord blood, such as in the treatment of diabetes, Alzheimer’s or Parkinson’s disease, but there is no conclusive evidence this research will lead to effective treatments.
Cord blood stem cells can be used in the treatment nearly 80 diseases today. Click on a category below to see specific diseases. Note: Banking cord blood does not guarantee that treatment will work and only a doctor can determine when it can be used.
Private banking guarantees the blood always will be available. However, the fees can include a first-year charge of $1000-3000, plus annual storage fees of $90-175. Most of the time, stored blood is eventually discarded or donated for use in research.
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!
Though cord blood banking has gotten more attention in recent years, it isn’t new. Cord blood has been collected to treat serious illnesses since the 1970s. And experts are continuing to learn how it can help with a growing number of diseases and disorders — from autism, heart birth defects and cerebral palsy to diabetes and Parkinson’s disease.
After your unit arrives at ViaCord’s Processing Lab, specialists will process your baby’s stem cells to maximize cell yield. They are then transferred to a transplant-ready cryobag for storage at or below ≤ -170º C (brrr). 
There are around 20 companies in the United States offering public cord blood banking and 34 companies offering private (or family) cord blood banking. Public cord blood banking is completely free (collecting, testing, processing, and storing), but private cord blood banking costs between $1,400 and $2,300 for collecting, testing, and registering, plus between $95 and $125 per year for storing. Both public and private cord blood banks require moms to be tested for various infections (like hepatitis and HIV).
Frances Verter, PhD, founded the Parent’s Guide to Cord Blood in 1998 and has been a Scientific Advisor to Community Blood Services since 2007. In 2011 the NMDP presented her with their Lifeline Award in recognition of her efforts to improve public education about cord blood donation.
When the medical courier delivers the cord blood collection kit to the cord blood bank, it is quickly processed to ensure the continued viability of the stem cells and immune system cells found in the cord blood. Firstly, a sample of the cord blood is tested for microbiological contamination, and the mother’s blood is tested for infectious diseases. As these tests are being conducted, the cord blood is processed to reduce the number of red blood cells and its total volume and isolate the stem cells and immune cells.
First, a little history. The first transplant took place in 1988 with a 5-year-old in Paris who was diagnosed with severe aplastic anemia. Post-treatment, the patient exhibits no signs of the disease and is now healthy over 25 years later.
These powerful cells play an important role in treating many life-threatening diseases. They can help someone who is sick and in need of a stem transplant now or in the near future. They could also help your child or another member of your family if they get sick later on. How the cells are used depends on the cord blood banking method you choose.
Whole genome sequencing is the process of mapping out the entire DNA sequence of a person’s genome. This test can show what type of health concerns we might face and most importantly how we can improve our health and quality of life.

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.
Since then, many families who suffered from a compatible disease grew hopeful for this newfound anecdote that seems to save so many lives effortlessly. This year to count there are 600,000 umbilical cord blood samples that have been stored and over 30,000 transplants performed. Cord blood can save lives, but cord blood banking may not be the right decision for you and your family. Read on to find out why.
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.
Collecting the cord blood is a noninvasive procedure, which is a good thing since it takes place during such an important event in a new mother’s (and baby’s) life. Once the baby is born, the blood is extracted from the umbilical cord and stored. It will either be picked up by the privately owned blood bank or donated to a local hospital. The most reassuring part is that the doctor is 100% responsible for the task at hand and is trained to do so efficiently.
