  1. The next step at either a public or family bank is to process the cord blood to separate the blood component holding stem cells. The final product has a volume of 25 milliliters and includes a cryoprotectant which prevents the cells from bursting when frozen. Typical cost, $250 to $300 per unit.
    Cord blood is the fastest growing source of stem cells in pediatric transplants, and ongoing research indicates that we’ve only just begun to harness the healing power of these amazing cells.3, 15 By collaborating with some of the country’s leading hospitals and research centers, ViaCord is helping to advance critical research in cord blood stem cell therapy and to unlock the promise of cord tissue stem cells.
    Description:  ViaCord, a PerkinElmer company, is an industry leading Cord Blood Collection and Storage company that was established in 1993.  Over the years ViaCord has added services such as Cord Tissue collection & storage, and newborn genetic screening.
    Public umbilical cord blood banks accept altruistic donations of cord blood and do not charge donation fees. Donated units are also processed, antigen typed, and frozen, ready for use. Unlike private banks, public banks do not reserve the units for the family that donated them; rather, units are available to the general public. In fact, a family that donates the blood would be no more likely to be a recipient of the blood than anyone else in the general population. Public cord blood banks function much like venous blood banks. The blood is released on an “as-needed” basis, and a processing fee may be charged to recoup some of the cost of storage (Moise, 2005; Percer, 2009).
    If you do decide to bank your baby’s cord blood, there’s one more thing to keep in mind: It’s best not to make it a last-minute decision. You should coordinate with the bank before your baby is born so nothing is left to chance.
    Family Cord, located in Los Angeles, has a high-quality lab, a top rating from the Better Business Bureau, and accreditation from AABB; it’s also been in business since 1997. Family Cord is one of the few banks that will also cover the cost of cord blood banking for the first year (there’s an annual fee after the first year) in cases where a baby has a sick sibling or another family member who could benefit from the cord blood.
    Save by paying in advance for 21 years of storage through our long-term storage plan. This plan covers all the initial fees (collection kit, courier service, processing, and preservation) and the cost of 21 years of continuous storage. A lifetime plan is also available; call for details.
    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).
    With umbilical cord blood harvesting, the harvested cord blood does not come from the newborn baby itself; instead, the cord blood is harvested from the blood that remains in the umbilical cord after birth. Umbilical cord blood is never harvested from either mother or child, but only from the unused blood in the umbilical cord, which would otherwise be discarded waste. The harvesting procedure takes only a few minutes and there is zero danger to either the parent or the baby.
    Make no mistake, cord banks are businesses to the core. And just like any other business, there’s always the possibility of a cord bank failing. Which is why we suggest begining your search by checking the company’s experience, the number cord blood units stored, and how many of these cord blood units have been used for transplants. 

  2. Research on stem cell transplants began in the 1950s, with successful bone marrow transplants occurring in the 1970s, often to treat cancer patients whose own bone marrow was destroyed by chemotherapy and radiation. The first successful umbilical cord blood stem cell transplant was reported as occurring in the late 1980s. The recipient was a 6-year-old American boy from North Carolina who was treated for Fanconi’s anemia (a genetic disorder) at Hospital St. Louis in Paris, France, using cord blood obtained from his younger sister’s birth. Interestingly, more than 20 years after the transplant, this young man is alive and well. Not only did he survive long term, but both his immune system and his blood were transformed by the transplant of his sister’s cord blood stem cells. Soon after this first documented cord blood stem cell transplant, the first public umbilical cord blood bank was established in 1991 in New York (McGuckin & Forraz, 2008).
    In a number of genetic, hematologic, immunologic, metabolic, and oncologic disorders, reconstitution of bone marrow (transplantation) can be a potentially life-saving procedure.1–16 Allogeneic (related or unrelated) or autologous (self) bone marrow or peripheral blood stem cells are the usual sources of hematopoietic progenitor cells to achieve this goal. If autologous stem cells are not available or cannot be used, the best option for successful reconstitution therapy is to secure stem cells from an HLA-matched sibling.1,3,11 Close matching confers a higher probability of successful engraftment and minimizes the risk of potentially fatal graft-versus-host disease. Unfortunately, there is only a 25% chance for identifying a full HLA match in a sibling donor.17,18
    There are several cord blood banks that are accredited by the American Association of Blood Banks. Most offer information on cord blood banking and provide private cord blood banking services. With a little research, you should be able to locate a credible cord blood bank online.
    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.
