Adverse effects are similar to hematopoietic stem cell transplantation, namely graft-versus-host disease if the cord blood is from a genetically different person, and the risk of severe infection while the immune system is reconstituted. There is a lower incidence with cord blood compared with traditional HSCT, despite less stringent HLA match requirements. 
The longest study to date, published in 2011 by Broxmeyer at al found that stem cells cyro-preserved for 22.5 years engrafted as expected. There was no significant loss of stem cell recovery or proliferation.
Private cord blood banking is recommended for families with a history of certain diseases. Specifically, these are families with diseases that harm the blood and immune system, such as leukemia and certain cancers, sickle-cell anemia, and some metabolic disorders. Why? The type of stem cells in cord blood can form all kinds of blood cells that can help treat these diseases.
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.)
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.
There has been considerable debate about the ethical and practical implications of commercial versus public banking. The main arguments against commercial banking have to do with questions about how likely it is that the cord blood will be used by an individual child, a sibling or a family member; the existence of several well-established alternatives to cord blood transplantation and the lack of scientific evidence that cord blood may be used to treat non-blood diseases (such as diabetes and Parkinson’s disease). In some cases patients may not be able to receive their own cord blood, as the cells may already contain the genetic changes that predispose them to disease.
Bone marrow is the soft, sponge-like material found inside bones. It contains immature cells known as hematopoietic or blood-forming stem cells. (Hematopoietic stem cells are different from embryonic stem cells. Embryonic stem cells can develop into every type of cell in the body.) Hematopoietic stem cells divide to form more blood-forming stem cells, or they mature into one of three types of blood cells: white blood cells, which fight infection; red blood cells, which carry oxygen; and platelets, which help the blood to clot. Most hematopoietic stem cells are found in the bone marrow, but some cells, called peripheral blood stem cells (PBSCs), are found in the bloodstream. Blood in the umbilical cord also contains hematopoietic stem cells. Cells from any of these sources can be used in transplants.
* Disclaimer: Banking cord blood does not guarantee that treatment will work and only a doctor can determine when it can be used. Cord tissue stem cells are not approved for use in treatment, but research is ongoing.
Cord tissue is rich in another type of stem cell. Although there are no current uses, researchers are excited about the benefits cord tissue stem cells may offer in potential future users, such as regenerative medicine. By storing both, you’ll have potential access to more possibilities
Choosing a bank (specifically a private bank) for her daughter’s cord blood made perfect sense to Julie Lehrman, a mom based in Chicago. “We wanted the extra assurance that we were doing everything we could to keep Lexi healthy,” Lehrman says. “I was older when Lexi was born, and there’s a lot we didn’t know about my mom’s health history, so we felt that we were making a smart decision.” Fortunately, Lexi was born healthy, and neither she nor anyone else in the family has needed the cord blood since it was stored seven years ago. But Lehrman has no regrets; she still feels the family made a wise investment. “Lexi or her brother or even one of us could still need that blood in the future, so I’m thankful that we have it.” But banking your child’s cord blood may not be the right decision for you. Read on to see if you should opt for private cord blood banking.
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.
The stem cells used for autologous transplantation must be relatively free of cancer cells. The harvested cells can sometimes be treated before transplantation in a process known as “purging” to get rid of cancer cells. This process can remove some cancer cells from the harvested cells and minimize the chance that cancer will come back. Because purging may damage some healthy stem cells, more cells are obtained from the patient before the transplant so that enough healthy stem cells will remain after purging.
A “tandem transplant” is a type of autologous transplant. This method is being studied in clinical trials for the treatment of several types of cancer, including multiple myeloma and germ cell cancer. During a tandem transplant, a patient receives two sequential courses of high-dose chemotherapy with stem cell transplant. Typically, the two courses are given several weeks to several months apart. Researchers hope that this method can prevent the cancer from recurring (coming back) at a later time.
Experts believe that umbilical cord blood is an important source of blood stem cells and expect that its full potential for treatment of blood disorders is yet to be revealed. Other types of stem cell such as induced pluripotent stem cells may prove to be better suited to treating non-blood-related diseases, but this question can only be answered by further research.
Umbilical cord blood is being studied for potential use in a wide variety of life-threatening diseases because it is a rich source of blood stem cells. Transplantation of blood stem cells from umbilical cords has been used successfully to treat several pediatric blood diseases, including sickle cell anemia and cancers such as leukemia and lymphoma. This procedure is still considered investigational. There is currently no solid evidence that umbilical cord blood stem cells have the ability to be transformed into other types of cells, such as replacement nerve tissue or myelin-making cells.
A “mini-transplant” (also called a non-myeloablative or reduced-intensity transplant) is a type of allogeneic transplant. This approach is being studied in clinical trials for the treatment of several types of cancer, including leukemia, lymphoma, multiple myeloma, and other cancers of the blood.
There are usually two fees involved in cord blood banking. The first is the initial fee that covers enrollment, collection, and storage for at least the first year. The second is an annual storage fee. Some facilities vary the initial fee based upon the length of a predetermined period of storage.
There is a high likelihood that immediate biological family members could benefit from the baby’s cord tissue stem cells, with parents having a 100% likelihood of being compatible, siblings having a 75% likelihood of being compatible, and grandparents having a 25% likelihood of being compatible.16,50 Another reason why parents today are choosing to bank their baby’s cord tissue for the future.
It’s hard to ignore the ads for cord blood banks, offering a lifetime of protection for your children. If you’re an expectant mom, there’s information coming at you constantly from your doctor’s office, magazines, online, and perhaps even your yoga class.
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.
One reason BMT and PBSCT are used in cancer treatment is to make it possible for patients to receive very high doses of chemotherapy and/or radiation therapy. To understand more about why BMT and PBSCT are used, it is helpful to understand how chemotherapy and radiation therapy work.
Americord® is committed to pioneering the development of new cord blood, cord tissue, and placenta tissue banking technologies. Under the leadership of Executive Medical Director, Dr. Robert Dracker, Americord® developed Cord Blood 2.0™. This revolutionary extraction process harvests up to twice as many stem cells compared to a traditional cord blood collection.
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.
Cord blood (short for umbilical cord blood) is the blood that remains in the umbilical cord and placenta post-delivery. At or near term, there is a maternal–fetal transfer of cells to boost the immune systems of both the mother and baby in preparation for labor. This makes cord blood at the time of delivery a rich source of stem cells and other cells of the immune system. Cord blood banking is the process of collecting the cord blood and extracting and cryogenically freezing its stem cells and other cells of the immune system for potential future medical use.
Cord Blood Registry® (CBR®) is the world’s largest newborn stem cell company. Founded in 1992, CBR is entrusted by parents with storing samples from more than 600,000 children. CBR is dedicated to advancing the clinical application of cord blood and cord tissue stem cells by partnering with institutions to establish FDA-regulated clinical trials for conditions that have no cure today.CBR has helped more than 400 families use their cord blood stem cells for established and experimental medical treatments, more than any other family cord blood bank. CBR’s goal is to expand the potential scope of newborn stem cell therapies that may be available to patients and their families.

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.
First isolated in 1998, there is a lot of controversy around acquiring embryonic stem cells. Thankfully, we can also acquire the stem cells that form just a little bit later down the road, like in the umbillical cord tissue. These stem cells, known as adult stem cells, stay with us for life. (Later, we will learn why not all adult stem cells are equal.) Adult stem cells are more limited in the types of cells they can become, something known as being tissue-specific, but share many of the same qualities. Hematopoietic stem cells (Greek “to make blood” and pronounced he-mah-toe-po-ee-tic) found in the umbilical cord’s blood, for instance, can become any of the different types of blood cells found in the body and are the foundation of our immune system. Another example is mesenchymal (meh-sen-ki-mal) stem cells, which can be found in the umbilical cord tissue and can become a host of cells including those found in your nervous system, sensory organs, circulatory tissues, skin, bone, cartilage, and more.
Options for Umbilical Cord Blood Banking and Donation—As expectant parents, learn how umbilical cord blood can help others through public donation, family (private) cord blood banking, or directed donation for a biological sibling.
If you’re looking to attain cord blood from a public bank, be aware that matched cord blood, as with bone marrow, can be difficult to obtain through a public cord blood bank. Once a match is ascertained, it may take valuable weeks, even months, to retrieve the match, and the cost of acquiring the cord blood from a public bank can be upwards of $40,000. When the newborn’s umbilical cord blood is banked privately, they can be retrieved quickly, and since the parents own the cord blood, banks can perform the retrieval free of charge. Learn more about public versus private cord blood banking here.
The use of cord blood is determined by the treating physician and is influenced by many factors, including the patient’s medical condition, the characteristics of the sample, and whether the cord blood should come from the patient or an appropriately matched donor. Cord blood has established uses in transplant medicine; however, its use in regenerative medicine is still being researched. There is no guarantee that treatments being studied in the laboratory, clinical trials, or other experimental treatments will be available in the future.
