Because of the invasive procedure required to obtain the bone marrow, scientist continued to look for a better source, which eventually lead to the discovery of similar stem cells in cord blood in 1978. Cord blood was used in its first transplant in 1988, and cord blood has since been shown to be more advantageous than other means of acquiring similar stem cells and immune system cells. This is because umbilical cord blood can be considered naïve and immature compared to other sources. Cord blood has not been exposed to disease or environmental pollutants, and it is more accepting of foreign cells. In this case, inexperience makes it stronger.
Private cord blood banking (also known as family banking), is preferred for families in a situation, where they currently have a family member suffering from a genetic disorder or have a family history of this type of disorder. By using a private cord blood bank, such as CariCord, your baby’s cord blood and tissue are stored for exclusive use by your family. It will always be there and readily available if it is ever needed. If it is donated to a public bank it can be accessed by anyone who is a match to it and there are no guarantees that it would be available, should your family ever need it later.
Access Immediately available once a match is confirmed. Search and match process may take weeks or months; ultimately, a match may not be located. Immediately available upon HLA match May take weeks or months; no match may be found
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.
In 2003, we reported that UCM cells can be induced in vitro to become cells with morphological and biochemical characteristics of neurons (26). These findings have been extended by others, for example, neurons (30–32), cardiac muscle, bone, and cartilage (29,32). Using two in vitro differentiation methods, Wang et al. (32) found that umbilical cord matrix stem (UCMS) cells could be induced to exhibit cardiomyocyte morphology and synthesize cardiac muscle proteins such as N-cadherin and cardiac troponin I. The cells responded to five azacytidine or culture in cardiomyocyte-conditioned media. Fu et al. (30) used media conditioned by primary rat brain neurons to induce human UCMS cells to synthesize NeuN neurofilament. Furthermore, they could invoke an inward current in UCM cells with glutamate. In that report, exposure to neural-conditioned media also increased the proportion of cells synthesizing the astroglial protein glial fibrillary acidic protein (GFAP) from 94% initially to 5% after 9 d, although the percentage had declined to about 2% by day 12. The multilineage potential of UCMS cells was also verified by Wang and colleagues (32), who showed that they could be induced in vitro into chondrogenic, osteogenic, and adipogenic lineages.

Operating both a family and public bank, CORD:USE cord blood units have been used in more transplants in the past 9 years than the two largest family cord blood banks have been involved in over their combined past 43 years of business2,3.
Some brochures advertising private cord blood banking show children with cerebral palsy, a neurological disorder, who were treated with their own stem cells. In the case of Cord Blood Registry, the company lists all stem cell transplants conducted at Duke University. In a list of individuals treated in their “stem cell therapy data” cerebral palsy is listed. However, transplants were part of an early research study and studies of efficacy are just now underway.
While cord-blood companies herald the possible future treatments of many adult diseases with stem cells, they rarely mention a key issue. Researchers have greater hopes for the potential of embryonic stem cells, which are thought to have the ability to develop into many different types of cells. It is not known whether the stem cells in cord blood have that ability; until recently, it was thought that they (like those in bone marrow) could only regenerate blood and immune cells.
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.

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.
Much research is focused on trying to increase the number of HSCs that can be obtained from one cord blood sample by growing and multiplying the cells in the laboratory. This is known as “ex vivo expansion”. Several preliminary clinical trials using this technique are underway. The results so far are mixed: some results suggest that ex vivo expansion reduces the time taken for new blood cells to appear in the body after transplantation; however, adult patients still appear to need blood from two umbilical cords. More research is needed to understand whether there is a real benefit for patients, and this approach has yet to be approved for routine clinical use.
It would be possible for a healthy child’s cord blood to be used to treat a sibling with leukemia, but the banks’ literature doesn’t spell out that distinction. In the last 10 years, almost all of the approximately 70 cord-blood transplants that have used privately stored blood were given to relatives with preexisting conditions, not to the donors themselves.
Most of the diseases on the proven treatment list are inherited genetic diseases. Typically, these treatments require a donor transplant, as from a sibling. In fact, research shows that treatments using cord blood from a family member are about twice as successful as treatments using cord blood from a non-relative.9a, 17 To date, over 400 ViaCord families have used their cord blood 56% were for transplant.1
During the harvesting procedure, doctors use a catheter to draw out blood. The blood moves through a machine, which separates stem cells and allows these cells to be put into storage. This process takes a few hours, and may be repeated over several days in order for doctors to get enough stem cells.
The European Group on Ethics in Science and New Technologies (EGE) has also adopted a position on the ethical aspects of umbilical cord blood banking. The EGE is of the opinion that “support for public cord blood banks for allogeneic transplantations should be increased and long term functioning should be assured.” They further stated that “the legitimacy of commercial cord blood banks for autologous use should be questioned as they sell a service which has presently no real use regarding therapeutic options.”
There are a few simple things that you need to do in order to donate cord blood. These include a medical history questionnaire, a consent form, a blood sample and maybe a follow up phone call. If you’re considering donating your baby’s umbilical cord blood, call the St. Louis Cord Blood Bank at 314-268-2787 or 888-453-2673 to register and download the required forms here. This can be done anytime before you deliver.
Generalized stem cell lineage concept. The lineage is characterized by a self-maintaining “parent” true stem cell population that resides within a specialized niche microenvironment, which aids the regulation of stem cell division or quiescence (nondividing). Derivative cells (called progeny or daughter cells) are of two types: symmetric division produces two identical daughter cells to expand or maintain the stem cell population; asymmetric division produces an identical daughter and a specialized cell (a differentiated cell). The differentiated cell is an intermediate type of precursor cell, termed the transient dividing population. The number of divisions of the intermediate precursor is fairly tightly regulated by microenvironment and inborn regulation factors. The intermediate precursors are thought to have a limited proliferative capacity. Further tissue-specific specialization continues form the intermediate precursors, producing specialized populations with a commitment to a progressively more specialized (differentiated) fate. The end points are fully differentiated cells that are nondividing and that live for various, tissue-specific periods prior to senescence or damage that leads to cell death. In some tissues, the naturally occurring cell loss produces various feedback signals that trigger normal cell replacement via amplification/differentiation of either stem cells or the intermediate precursors.
The cord is cut and clamped, just like normal. The mother doesn’t go through anything different during birth, and neither does her child. They will experience no additional pain or procedures before, during, or after birth.
Like any insurance, cord-blood banking isn’t cheap. Banks initially charge from $1,000 to $2,000 to collect and process the stem-cell units, which are stored for a family’s exclusive use. When you factor in additional costs for shipping (about $150 for a medical courier), the doctor’s collection fee (prices can range from $150 to $500), and annual storage fees averaging $100 per year for 18 years, parents can expect to pay up to $4,000 in expenses not covered by insurance.
Women typically sign up for cord blood banking between the 28th and 34th week of pregnancy. Some private banks will allow for early or late sign up, but most public storage facilities won’t accept any mother past her 34th week. While most banks don’t officially sign up mothers until a certain time, it’s never too early to research.
Today, cord blood stem cells have been used in more than 35,000 transplants worldwide to regenerate healthy blood and immune systems, like in a bone marrow transplant. 1* Find out which conditions have been treated here.
Another contributor to cord blood banking costs is the quality of the collection kit. Cheaper banks typically use flimsy collection kits. To insure the survival of newborn stem cells, the shipping container should be thermally insulated to maintain kit temperature during cord blood shipments.
Your adult cells have one disadvantage to cord blood cells – they cannot change their cell type. When stem cells from cord blood and tissue are transplanted, they adjust to fit the individual patient and replace damaged cells. Adult stem cells are also older, which means they have been exposed to disease, and may damage patients after the transplant. Compared to cord blood cells, adult cells have a higher chance for graft-versus-host disease.
When a donor signs up with a public bank, the mother must pass a health screening and sign a consent form. After that, the bank processes the application, which makes last-minute donations impossible. However, there are a small number of banks that accept late donor requests.
Upon arrival at CBR’s laboratory, the kit is immediately checked in and inspected. Next, the cord blood unit is tested for sterility, viability, and cell count. In addition, the cord tissue is tested for sterility. CBR processes cord blood using the AutoXpress® Platform* (AXP®) – a fully automated, functionally closed stem cell processing technology. The AXP platform is an integral component of CBR’s proprietary CellAdvantage® system. CBR has the industry’s highest published average cell recovery rate of 99%.
