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.

The Medical Letter On Drugs and Therapeutics also recently addressed aspects of public and private cord blood banks, asking the question: “Does Private Banking Make Sense?” After citing various statistics on the actual uses of privately stored cord blood, they concluded that: “At the present time, private storage of umbilical cord blood is unlikely to be worthwhile. Parents should be encouraged to contribute, when they can, to public cord blood banks instead.” [Access The Medical Letter at www.medicalletter.org].
Part of the reason for the dominance of these three companies in terms of the total number of units stored is that they are three of the oldest cord blood banks within the U.S., founded in 1992, 1993, and 1989, respectively. All three of these cord blood banks also support cord blood research and clinical trials.
For families who wish to donate cord blood to a public bank, the biggest hurdle may be finding a nearby hospital that collects cord blood for donation. Most public banks only work with select hospitals in their community. In the U.S., there are only about 200 hospitals that collect cord blood donations. Find out if there is a donation hospital near you.
Your baby’s umbilical cord is made up of tissue and contains blood. Both cord blood and cord tissue are rich sources of powerful stem cells. Cord blood stem cells are currently used in transplant medicine to regenerate healthy blood and immune systems. These cells are being researched for their ability to act like our body’s own personal repair kit and may be able to help our bodies heal in new ways.
A major limitation of cord blood transplantation is that the blood obtained from a single umbilical cord does not contain as many haematopoeitic stem cells as a bone marrow donation. Scientists believe this is the main reason that treating adult patients with cord blood is so difficult: adults are larger and need more HSCs than children. A transplant containing too few HSCs may fail or could lead to slow formation of new blood in the body in the early days after transplantation. This serious complication has been partially overcome by transplanting blood from two umbilical cords into larger children and adults. Results of clinical trials into double cord blood transplants (in place of bone marrow transplants) have shown the technique to be very successful. Some researchers have also tried to increase the total number of HSCs obtained from each umbilical cord by collecting additional blood from the placenta.
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.

The term “Cord Blood harvesting” has a slightly morbid sound, but in reality, it is a very worthwhile and potentially lifesaving field of medical science. Umbilical Cord blood is blood that remains in the umbilical cord after birth. This umbilical cord blood is full of…

Cord blood cannot be used if the donor (baby) contains the same genetic illness as the recipient. Most cord blood banks glaze over this, but it is important to understand that the odds of using cord blood for the same child are much lower than the odds of using them for a sibling.
“One of the wonderful things about cord blood is that unlike bone marrow, you don’t always need a perfect match in order for it to work,” says Dr. Kurtzberg, who performed the first unrelated cord-blood transplant in the U.S. And it was a public donation that ultimately saved Anthony Dones. Within a week of starting a search, the National Cord Blood Program, a public bank operated by the New York Blood Center, found a “close enough” match. Had the now-3-year-old been forced to rely on a bone-marrow match, he might still be waiting.
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 are over 130 public cord blood banks in 35 countries. They are regulated by Governments and adhere to internationally agreed standards regarding safety, sample quality and ethical issues. In the UK, several NHS facilities within the National Blood Service harvest and store altruistically donated umbilical cord blood. Trained staff, working separately from those providing care to the mother and newborn child, collect the cord blood. The mother may consent to donate the blood for research and/or clinical use and the cord blood bank will make the blood available for use as appropriate.
When Tracey and Victor Dones’s 4-month-old son was diagnosed with osteopetrosis, a potentially fatal disorder that affects bone formation, the panic-stricken couple was relieved to hear that a stem-cell transplant could save his life. “We’d paid to store Anthony’s umbilical-cord blood in a private bank in case he ever needed it — and I thought we were so smart for having had the foresight to do that,” says Tracey.
The American Academy of Pediatrics supports efforts to provide information about the potential benefits and limitations of cord blood banking and transplantation so that parents can make an informed decision. In addition, the American College of Obstetricians and Gynecologists recommends that if a patient requests information on umbilical cord blood banking, balanced information should be given. Cord blood education is also supported by legislators at the federal and state levels. In 2005, the National Academy of Sciences published an Institute of Medicine (IoM) report titled “Establishing a National Cord Blood Stem Cell Bank Program”.
There is no significant opposition in the medical community to the public banking of cord blood. The donation of cord blood to public banks has generally been encouraged by the medical profession. The American Academy of Pediatrics encourages the public donation of cord blood with appropriate genetic and infectious disease testing, although they caution that parents should be notified that they will receive the results of this testing. They also recommend that parents be informed that publicly banked cord blood may not be available for future private use.
For example, in the UK the NHS Cord Blood Bank has been collecting and banking altruistically donated umbilical cord blood since 1996. The cord blood in public banks like this is stored indefinitely for possible transplant, and is available for any patient that needs this special tissue type. There is no charge to the donor but the blood is not stored specifically for that person or their family.
An additional cost that is borne only by public banks is the “HLA typing” that is used to match donors and patients for transplants. This is an expensive test, running about $75 to $125 per unit. Family banks always defer this test until it is known whether a family member might use the cord blood for therapy.
Most public banks only work with selected hospitals in their community. They do this because they need to train the staff who will collect the cord blood, and they want the blood to be transported to their laboratory as quickly as possible. A parent who wants to donate should start by finding public banks in your country.
However, parents should know that a child’s own cord blood (stored at birth), would rarely be suitable for a transplant today. It could not be used at present to treat genetic diseases, for example, because the cord blood stem cells carry the same affected genes and. if transplanted, would confer the same condition to the recipient. (See the story of Anthony Dones.) In addition, most transplant physicians would not use a child’s own cord blood to treat leukemia. There are two reasons why the child’s own cord blood is not safe as a transplant source. First, in most cases of childhood leukemia, cells carrying the leukemic mutation are already present at birth and can be demonstrated in the cord blood. Thus, pre-leukemic cells may be given back with the transplant, since there is no effective way to remove them (purge) today. Second, in a child with leukemia, the immune system has already failed to prevent leukemia. Since cord blood from the same child re-establishes the child’s own immune system, doctors fear it would have a poor anti-leukemia effect.

The Cord Blood Registry (CBR) is unique, because it is currently the world’s largest cord blood bank, with over a half-million cord blood and cord tissue units stored to date. This is substantially more than its nearest competitor, ViaCord, which has 350,000 units stored. It was recently acquired by pharmaceutical giant, AMAG Pharmaceuticals, for $700 million in June 2015.
* 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.
Not surprisingly, this emotional pitch is working — especially because the seemingly unlimited potential of stem cells has dominated the news in recent years. From 2003 to 2004, for example, the number of couples opting to use a private bank increased by 55 percent to 271,000. The three biggest companies — who have the majority of the approximately $250 million market — are vying for business.
