In recent years, umbilical cord blood, which contains a rich source of hematopoietic stem and progenitor cells, has been used successfully as an alternative allogeneic donor source to treat a variety of pediatric genetic, hematologic, immunologic, and oncologic disorders. Because there is diminished risk of graft-versus-host disease after transplantation of cord stem cells using matched related donors, the use of less-than-completely matched HLA cord blood stem cells may incur less risk of graft-versus-host disease than mismatched cells from either a related or unrelated “walking” donor, although this remains to be proven. Gene-therapy research involving modification of autologous cord blood stem cells for the treatment of childhood genetic disorders, although experimental at the present time, may prove to be of value. These scientific advances have resulted in the establishment of not-for-profit and for-profit cord blood–banking programs for allogeneic and autologous cord blood transplantation. Many issues confront institutions that wish to establish or participate in such programs. Parents often seek information from their physicians about this new biotechnology option. This document is intended to provide information to guide physicians in responding to parents’ questions about cord blood donation and banking and the types and quality of cord blood banks. Provided also are recommendations about appropriate ethical and operational standards, including informed consent policies, financial disclosures, and conflict-of-interest policies for physicians, institutions, and organizations that operate or have a relationship with cord blood–banking programs.
This is absolutely rare and unique technology to infuse the pure organic oil with the sunlight frequency waves and vibrations that almost instantly have an incredible effect on the body, either from the physiological point of view or spiritual. The small drop of the sunlight oil immediately affects the blood cells and create an easy and stress-free blood flow, balancing and harmonizing the entire body system as well as giving the energy boost for the whole day.
ViaCord collaborates with leading research and medical centers across the country to help advance medical treatments using cord blood, discover treatments using cord tissue, and connect families to relevant clinical trials.
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).
With public cord blood banks, there’s a greater chance that your cord blood will be put to use because it could be given to any child or adult in need, says William T. Shearer, M.D., Ph.D., professor of Pediatrics and Immunology at Baylor College of Medicine in Houston. Cord blood is donated and is put on a national registry, to be made available for any transplant patient. So if your child should need the cord blood later in life, there’s no guarantee you would be able to get it back.

A typical cord blood collection only contains enough stem cells to transplant a large child or small adult.  This website has a page explaining the optimum transplant dose.  At one time it was believed that cell dose limitations restricted the use of cord blood transplants to children.  In recent years growing numbers of adults are also receiving cord blood transplants, either by growing the cells in a lab prior to transplant or by transplanting more than one cord blood unit at a time.  More information about these trials is available on the web page about Research on Cord Blood Transplants.
M.A.Z.E. Cord Blood Laboratories is an FDA-approved and regulated storage facility that partners with Community Blood Services for processing. The company has processed over 30,000 units of cord blood since opening in 1997.
Stem cells in the umbilical cord blood were first discovered in 1978. The stem cells found in cord blood give rise to all the other blood cells and are the foundation of our bodies’ immune system. More recently, scientists discovered a rich supply of a different type of stem cell in the cord tissue. These stem cells give rise to the tissues that comprise our nervous system, sensory organs, circulatory tissues, skin, bone, cartilage and more.
The process for umbilical cord blood harvesting is straightforward: An obstetrician or doctor harvests the umbilical cord blood at the time of the baby’s birth. Timing is very important, as the umbilical cord blood must be harvested quickly so that the cells remain fresh. The harvested umbilical cord blood should preferably be at least 75 mL to make sure that there is enough cord blood and stem cells to be transplanted at a later stage.
The most obvious argument against is that the odds of needing cord blood for medical treatment is very, very slim.  Below is a news release on a policy published in the July,1999 issue of Pediatrics, the peer-reviewed scientific journal of the American Academy of Pediatrics (AAP):
Laughlin MJ, Rizzieri DA, Smith CA, et al. Hematologic engraftment and reconstitution of immune function post unrelated placental cord blood transplant in an adult with acute lymphocytic leukemia. Leuk Res.1998;22 :215– 219
Cord tissue contains a special type of stem cell that has the potential to treat injuries and diseases affecting cartilage, muscle, and nerve cells.19 Since 2007 there have been about 150 clinical trials that have used cord tissue stem cells in human patients.
The stem cells obtained from umbilical cord blood are also less likely than bone marrow stem cells to be rejected in transplants. Considered to be immunologically immature, umbilical cord blood stem cells produce significantly fewer natural killer cells, creating a substantial decrease in rejection. Consequently, cord blood stem cells require less rigorous antigen tissue matching for transplants than bone marrow stem cells (Sullivan, 2008). Research indicates that a mismatch of up to two antigen sites still provides successful clinical outcomes (Ballen, 2006; Fox et al., 2007). In fact, researchers report that the rate of rejection for cord blood stem cell transplants is half the rate of rejection for bone marrow transplants (Ballen et al., 2001). When compared directly in cases of mismatched antigens, there was clearly less rejection in transplants involving cord blood stem cells than bone marrow stem cells (Moise, 2005).

Americord offers parents the ability to collect stem cells from the placenta and umbilical cord soon after the child’s birth. These stem cells, obtained from cord blood, cord tissue and placenta tissue, can be used to help treat genetic diseases and other threats to the baby’s life. Placenta tissue stem cells can also be used to benefit the mother.
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.
Cord blood donation should be discouraged when cord blood stored in a bank is to be directed for later personal or family use, because most conditions that might be helped by cord blood stem cells already exist in the infant’s cord blood (ie, premalignant changes in stem cells). Physicians should be aware of the unsubstantiated claims of private cord blood banks made to future parents that promise to insure infants or family members against serious illnesses in the future by use of the stem cells contained in cord blood. Although not standard of care, directed cord blood banking should be encouraged when there is knowledge of a full sibling in the family with a medical condition (malignant or genetic) that could potentially benefit from cord blood transplantation.

Well, this is how the entire procedure of cord blood banking. Right after the blood is extracted, it is sent for to the bank. In the bank, the cord blood is checked, tested, processed and finally preserved. This preservation is ensured by controlled freezing under high end freezing conditions. Certain private banks collect a certain segment of the umbilical cord along with the cord blood. The umbilical cord tissue contains various stem cells that are quite different from the general cord blood cells. Research experts are studying in order to understand the possible use of the stem cells in medicine.
The choices expectant parents make today go beyond finding out the gender of their baby. They span beyond deciding whether to find out if their child, still in the womb, may potentially have a genetic disorder. Today, many parents must decide whether to store their baby’s umbilical cord blood so it will be available to heal their child if at any point in the child’s lifetime he or she becomes sick.
Another advantage of using umbilical cord blood stem cells is the decreased risk of the transmission of infectious disease. This particular advantage is partly because umbilical cord blood is almost never contaminated by Epstein-Barr virus or cytomegalovirus (Drew, 2005; Gonzalez-Ryan et al., 2000). Additionally, the processing of cord blood includes collecting data on the history of infection during the mother’s pregnancy. For example, if the pregnant woman has a history of group B streptococcus, active genital herpes, or prolonged rupture of membranes and chorioamnionitis, umbilical cord blood is not saved. Generally, samples of the mother’s blood are also drawn to test for infectious diseases, such as hepatitis, human immunodeficiency virus, and syphilis (Moise, 2005). Furthermore, after the cord blood units are collected, they are screened for disease, and any units that are deemed contaminated or infected are thrown away (Gunning, 2007).
The American College of Obstetricians and Gynecologists (ACOG, 2008) recommends giving pregnant women information about umbilical cord blood banking that is free from bias. According to ACOG, the chance of a child or family member needing a stem cell transplant is about 1 in 2,700. Therefore, ACOG recommends the collection and banking of cord blood only when an immediate family member has a known diagnosis for which stem cells are currently being used for treatment, and not for potential future uses.
24/7 opperation of services, including holidays, is a must.  As we all know, giving birth can happen at any time of day, which is why core blood banks should be at the ready for whenever your little one make his or her grand debut. Select a cord blood bank that utilizes industry approved standards for shipping. Temperature fluctuations speeds up cell death which affects the number of viable cells that reaches the laboratory for storage. Cord blood banks which use commercial shipping services, such as FedEx, use heavily insulated boxes to protect specimens. While others use medical couriers who specialize in delivering medical specimens, for added protection of your cord blood or tissue specimens.
Many public banking proponents believe that the greater good to society is to donate your baby’s cord blood stem cells to a public bank for use by someone who may need it, since the likelihood of your baby needing it is very small.
Cord Blood Registry is a cord blood storage company that collects, processes and stores stem cells to help families with medical needs later in life. Founded in 1992, it is the world’s largest newborn stem cell company.
When you consider that public banks can only expect to ship 1-2% of their inventory for transplant, you can quickly understand why most public banks are struggling to make ends meet. That struggle means that fewer collection programs are staffed, and there are fewer opportunities for parents to donate to the public good. We said earlier that public banks only keep cord blood donations over a minimum of 900 million cells, but today most public banks have raised that threshold to 1.5 billion cells. The reason is that the largest units are the ones most likely to be used for transplants that bring income to the bank. Family cord blood banks do not need to impose volume thresholds because they have a profit margin on every unit banked.
Current applications for newborn stem cells include treatments for certain cancers and blood, metabolic and immune disorders. Additionally, newborn stem cell preservation has a great potential to benefit the newborn’s immediate family members with stem cell samples preserved in their most pristine state.
The baby’s cord blood will be processed and stored in a laboratory facility, often referred to as a blood bank. The cord blood should be processed and stored in a facility that is accredited by the American Association of Blood Banks (AABB) for the purpose of handling stem cells.
Physicians or other professionals who recruit pregnant women and their families for for-profit placental cord blood stem cell banking should disclose any financial interest or other potential conflict of interest they have in the procedure to their patients.
Anyway, the excitement over the embryonic cells comes from their remarkable ability, as biological blank slates, to become virtually any of the body’s cell types. Many observers believe the president’s move will accelerate the hunt for cures for some of our most vexing diseases. However, the benefits are largely hypothetical, given the infancy of the field, and are offset by some real obstacles: The risks of embryonic stem cells, as well as cells programmed to become like them, including the possibility they will actually cause cancers in people who receive them. Nonetheless, here’s a look at 10 health problems that stem cells might someday cure or at least help treat.
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
You need to plan ahead if you decide to store cord blood. Banks need to be notified four to six weeks before your due date if you’re interested in donating blood. Once you do decide on a public bank, those affiliated with the Be the Match registry (bethematch.org/cord) will cover the costs of collecting, processing, and storing cord blood units.
Carolinas Cord Blood Bank, established in 1998, is one of the largest public cord blood banks. It’s affiliated with Duke University, where trials are currently taking place to treat children with cerebral palsy with their own cord blood. Parents can mail in their cord blood donations and receive financial aid if they have a sick older child or family member who can be treated with cord blood.
Donating to research is another alternative. In some areas, you may be able to donate your newborn’s cord blood stem cells to a university or biotech firm. There are also now several private banks who offer to bank your baby’s cord blood as a donation, but they will typically sell it to a research facility. Cord Blood Options will be compiling additional data for this section in the near future.
These are diagnoses for which stem cell treatments are being studied either in the laboratory with cell cultures or in animals that mimic the human disease. The experimental therapies are not yet in human clinical trials. In experimental research, it is often not clear whether an eventual therapy, if developed, would be Autologous or Allogeneic.

Over 95% of newborns’ cord blood stem cells fall into this category. It is unfortunate that public banking is not readably available and private banking is so expensive. Some industry leaders believe that as the industry grows, banking or donating cord blood will be as common as it is uncommon today.
Initially, cord blood stem cell transplantation using allogeneic umbilical cord blood was performed in relatively small children, because the cell dose per weight of recipient was shown to be important.19,20 However, older children, adolescents, and adults have benefited from unrelated allogeneic umbilical cord blood transplantation.34,55–61 Because of the relationship between cell dose per recipient weight and transplant outcome, the number of cord blood cells needed for marrow reconstitution in older children or young adults is much larger than that needed when cord blood is used for transplantation in small children. Cord blood transplants using multiple cryopreserved units from separate donors have been performed successfully in adults, and the approach is currently under investigation as a strategy to increase the dose of cells for transplantation in a single recipient.62 Cord blood is collected in observance of good obstetric and pediatric practice.45
So what are your options? You have three choices. One is to store the cord blood with a private company at a cost to you ranging from $1,500 to $2,500 and an annual storage fee in the ballpark of $125. Secondly, you can donate the cord blood to a public bank, if there is one working with your hospital, and your doctor is on board with the idea. There are also public banks that accept mail-in donations, if you register during your second trimester and your doctor is willing to take a short training class on-line. Zero cost to you. The third option is to do nothing and have the cord blood, umbilical cord, and placenta destroyed as medical waste.
9. Sickle cell anemia. Stem cell researchers are exploring ways to correct numerous blood disorders, including sickle cell anemia. Mice have been cured of the sometimes-deadly condition after receiving transfusions of stem cells made from their own skin cells.
Despite the benefits of using umbilical cord blood stem cells for transplant, the process also has some disadvantages (see Table 3). For stem cell transplants to be successful, measurable signs of engraftment must occur. Engraftment is the opposite of rejection and indicates that the stem cell transplant is “working.” Two measurable signs of engraftment are the recovery of both neutrophil (a type of white blood cell) and platelet (a clotting factor) production. These two clinical signs of recovery take longer to occur in umbilical cord blood stem cell transplants than in bone marrow stem cell transplants. In other words, the lab values for white blood cell production and platelet production take longer to increase after umbilical cord blood stem cell transplants than after bone marrow stem cell transplants (Hess, 1997; Moise, 2005).
5. Alzheimer’s disease. Likewise, embryonic stem cells may come in handy against Alzheimer’s disease, a progressive and deadly disorder that degrades and kills brain cells, leading to memory loss, cognitive decline, and behavioral problems. Stem cells may give rise to new treatments or even, some say, a cure; other experts have expressed skepticism.
Only three to five ounces of blood is collected from each umbilical cord. This small amount is enough to treat a sick child, but not an adult, unless multiple units of matched cord blood are used, says William T. Shearer, M.D., Ph.D., professor of Pediatrics and Immunology at Baylor College of Medicine in Houston.
