To begin a discussion of umbilical cord blood banking, it must first be understood that the component from the blood that is salvaged is the stem cells. Stem cells are unspecialized cells that are the basis of all tissue and organ cells of the body. There are three main sources of stem cells in humans: embryonic stem cells, adult stem cells, and umbilical cord stem cells. Embryonic stem cells are generally used in research but not in clinical practice. Adult stem cells are found in various locations in the human body, but they are most commonly found in bone marrow (McGuckin & Forraz, 2008). Over the years, transplants of bone marrow stem cells have been used clinically to treat disease processes in which stem cells are beneficial. Umbilical cord blood stem cells were historically considered a waste product of the birthing process but are now known to have up to 10 times more stem cells than adult bone marrow (Gunning, 2007).
Most of the diseases for which HSCT is a standard treatment are disorders of blood cell lineage. The proliferation by which blood cells are formed from stem cells is illustrated in the side graphic (click on the image to expand it); you can also read about specific cell types in the immune system in more detail. In the United States, most health insurance providers will pay for a stem cell transplant if it is a “standard therapy” for the patient’s diagnosis.
Medical shipping: Some cord blood companies use medical shipping companies to deliver cord blood; these companies guarantee that cord blood is kept a certain temperature and delivered to the facility by a certain time, typically within 24 hours of collection.

Now when you know what is cord blood, you might be wondering how it is collected. Well, cord blood is collected right after the birth of your little one. The procedure is completely painless and free from risks as well. The procedure is so quick, hassle-free and painless that neither a newborn nor a new mother realizes the entire procedure has taken place. Following is a list of steps depicting how the procedure is actually convened. Read on, to grasp a better insight on cord blood banking and its proceedings.
3. Families should consider is whether the odds given for the “average baby” apply to them. Some families do have a higher predisposition to cancer and immune disorders and would be far more likely to benefit from cord blood banking than the statistics indicate.
CBR’s quality control team performs over 5 million sample checks per year which includes 3 million temperature checks, 20,000 environmental sterility tests, and 95 control checks on each sample to ensure processes are working correctly so that your family’s stem cells are kept protected. At CBR we take the safe storage of your stem cells seriously.
All cord blood banks in the US are required to register with Food and Drug Administration. To ensure safety, cord blood banks must comply with FDA regulations, including current good tissue practice regulations, donor screening and testing for infectious diseases, including HIV I & II (the virus that causes AIDS), Hepatitis B & C, which can cause liver disease, Cytomegalovirus (CMV) a virus that can lead to pneumonia, Human T-cell Lymphotropic Virus (HTLV) 1 & 2, which can suppress the immune system, West Nile Virus, Zika Virus, Treponema pallidum (the bacterium that can cause syphilis) and Variant Creutzfeldt-Jakob Disease (vCJD), a rare virus that can cause brain disease. Since 2011, the FDA has required public cord blood banks to obtain a license under a Biologics License Application.
The American Academy of Pediatrics (AAP, 2007) states that the use of banked umbilical cord blood as “biologic insurance” is unwarranted. The AAP also notes that many of the claims of private cord blood banks are unfounded. Unlike ACOG, the AAP recommends cord blood collection and banking for all families; however, their distinction is that all cord blood should be banked in public banks for use by the general population. In one study, the researchers reported that when pediatric transplant specialists were surveyed, overall, they did not recommend private cord blood banking (Thornley et al., 2009). The AAP recommends private cord blood banking only if a full sibling has a medical diagnosis for which stem cells are currently being used for treatment.





Although cord blood is currently considered discarded human material, it should only be collected for banking with an institutional review board–approved protocol and with signed informed consent from a parent.42,43 Pertinent donor information communicated to the cord blood bank should be kept confidential by the cord blood bank and used only to report important medical information obtained during the cord blood collection, processing, and screening process that is relevant to the safety of the donor and family. If cord blood was collected from a newborn who subsequently developed a genetic, immunologic, or malignant neoplastic disorder, parents should notify the cord blood bank so that the unit is not used for transplantation. All cord blood units banked for potential use should be tested for infectious diseases, similar to those tested in a blood bank, and for hereditary hematologic diseases. The informed consent must contain information pertaining to what tests are to be performed on the cord blood and how the parents will be informed if test results are abnormal. Pediatricians should be aware that legal cases relating to the duty of a physician to warn parents about the risks of inheriting a genetic disease are new and untested. Pediatricians should remain vigilant, because future cases may define who has a legal duty to notify parents about genetic abnormalities identified during cord blood testing. Informed consent should be obtained before the onset of active labor and before cord blood collection.
Quite simply, cord blood is the remaining blood from your baby’s umbilical cord and placenta after birth.  Cord blood is loaded with our “stem cells” which are origins of the body’s immune and blood system and maybe the origin of other organs and important systems in the body.  Stem cells are important because they have the ability to regenerate into other types of cells in the body.
For transplants, the primary advantage of cord blood stem cells over stem cells from adults is that they cause much less graft versus host disease (GvHD).  In order to safely transplant adult stem cells, the patient and donor must match over at least 10 of 12 tissue types called Human Leukocyte Antigens (HLA), or 83% HLA match.  By comparison, medical outcomes are just as good with cord blood that has a 4 out of 6 or 67% HLA match.

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.
Clinical experience with leading institutions: Many reputed hospitals have depended on the company for cord blood, including Duke University, Children’s Healthcare of Atlanta and the University of Minnesota Medical Center.

There are three types of umbilical cord blood banks: private, public, and direct-donation banks. The private bank is a commercial, for-profit entity that often advertises directly to expectant parents. These banks are designed for the sole use of the families who have saved the cord blood. Private banks charge an initial fee for collection and processing and, then, a yearly fee to maintain the specimen. Another fee is often charged when a sample is removed for testing or treatment (Moise, 2005).
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.
Regenerative therapy is the practice of delivering cells and cell products to renew diseased or damaged tissues in a specific area. It is one of the fastest growing fields of medical research. Each year, new regenerative therapies using stem cells from cord blood and cord tissue enter into clinical trials for the treatment of chronic and life-threatening diseases. If proven successful, these clinical trials will lead to approval from the Food and Drug Administration (FDA). With FDA-approval, these treatments can then be administered as a general practice.
In recent years, umbilical cord blood has been used successfully to treat a variety of pediatric genetic, hematologic and oncologic disorders. This advance has resulted in both not-for-profit and for-profit cord blood banking programs. The AAP’s statement is intended to help guide physicians in answering parents’ questions about cord blood banking.
Additional ethical concerns about umbilical cord blood banking involve the timing of clamping the umbilical cord after birth. Overall, the issue of when to clamp and cut the umbilical cord is controversial. There is no consensus on how early or how late in the birthing process the umbilical cord ought to be clamped and cut, although the cord obviously still provides nourishment and removes waste until it is clamped or spontaneously stops pulsing (Lothian & DeVries, 2010). However, some practitioners might clamp the umbilical cord early in an effort to maximize the amount of cord blood obtained for banking, and thus “short change” the child and allow the infant to become anemic (Drew, 2005).
The blood within your newborn baby’s umbilical cord contains young stem cells that can renew themselves and become specialized. These cord blood stem cells have been proven in treatment to help children replace damaged blood cells with healthy ones and strengthen their immune systems. Cord blood banking is the process of collecting and storing these stem cells for potential medical use.
However, this does not mean more is better. Cord blood banks we reviewed are similar in terms of the quality of services they provided. Affordable services are still available, especially with the different discount options offered by many of the top cord blood banks reviewed.
