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…
Unlike other banks, CBR uses a seamless cryobag for storage. The seamless construction decreases the potential for breakage that can occur in traditional, seamed-plastic storage bags. Prior to storage, each cryobag is placed in a second overwrap layer of plastic, which is hermetically sealed as an extra precaution against possible cross contamination by current and yet unidentified pathogens that may be discovered in the future. CBR stores the stem cells in vaults, called dewars, specially designed for long-term cryostorage. The cord blood units are suspended above a pool of liquid nitrogen that creates a vapor-phase environment kept at minus 196 degrees Celsius. This keeps the units as cold as liquid nitrogen without immersing them in liquid, which can enable cross-contamination. Cryopreserved cord blood stem cells have proven viable after more than 20 years of storage, and research suggests they should remain viable indefinitely.
Prior to freezing the cells, samples are taken for quality testing. Banks measure the number of cells that are positive for the CD34 marker, a protein that is used to estimate the number of blood-forming stem cells present. Typical cost, $150 to $200 per unit. They also measure the number of nucleated cells, another measure of stem cells, both before and after processing to determine the cell recovery rate. Typical expense, $35 per unit. A portion of the sample is submitted to check that there is no bacterial or fungal contamination. Typical expense, $75 per unit. Public banks will also check the ability of the sample to grow new cells by taking a culture called the CFU assay. Typical expense, $200 to $250 per unit.
The cord blood collection process is simple, safe, and painless. The process usually takes no longer than five minutes. Cord blood collection does not interfere with delivery and is possible with both vaginal and cesarean deliveries.
Companies throughout Europe also offer commercial (private) banking of umbilical cord blood. A baby’s cord blood is stored in case they or a family member develop a condition that could be treated by a cord blood transplant. Typically, companies charge an upfront collection fee plus an annual storage fee.
Since the first successful sibling-to-sibling cord-blood stem-cell transplant was performed in 1988 to treat a genetic disorder called Fanconi’s anemia, more than 20 private banks have opened. And they seem to have the address of every expectant couple in America — whose mailboxes bulge with brochures encouraging them to take advantage of this once-in-a-lifetime opportunity. “Cord-blood banking is like insurance to protect your family against unforeseeable events,” says Stephen Grant, cofounder and senior vice president of Cord Blood Registry, a large California-based private bank. “You do it out of love and responsibility for your family. Sure, you hope you’ll never have to use the blood, but if you do, it’ll be there.”

Like most transplants, the stem cells must be a genetic match with the patients to be accepted by the body’s immune system. It goes without saying that a patient’s own cord blood will be a 100% match. The second highest chance of a genetic match comes from siblings.
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.
Though uses of cord blood beyond blood and immunological disorders is speculative, some research has been done in other areas. Any such potential beyond blood and immunological uses is limited by the fact that cord cells are hematopoietic stem cells (which can differentiate only into blood cells), and not pluripotent stem cells (such as embryonic stem cells, which can differentiate into any type of tissue). Cord blood has been studied as a treatment for diabetes. However, apart from blood disorders, the use of cord blood for other diseases is not in routine clinical use and remains a major challenge for the stem cell community.
Clearly, it is advantageous to save cord blood stem cells, but it can be confusing to decide where to store them. There are currently two options: public cord blood banks and private cord blood banks. Public and private banks serve very different purposes, and it is important to know which type of bank would be more beneficial to you and your family.
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.
Private cord blood banking can benefit those with a strong family history of certain diseases that harm the blood and immune system, such as leukemia and some cancers, sickle-cell anemia, and some metabolic disorders. Parents who already have a child (in a household with biological siblings) who is sick with one of these diseases have the greatest chance of finding a match with their baby’s cord blood. Parents who have a family history of autism, Alzheimer’s, and type 1 diabetes can benefit from cord blood. Although these diseases aren’t currently treated with umbilical cord steam cells, researchers are exploring ways to treat them (and many more) with cord blood.
Even if a sick child has a sibling donor, there’s only a 25 percent chance that cord blood will be a perfect match — and an equal chance it won’t match at all. That’s why public donations are so important. So far, many more stem-cell transplants have been done using cord blood stored in public banks. From 2000 to 2004, more than 2,200 unrelated transplants were done nationwide.
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.

The majority of programs that accept cord blood donations require the mother to sign up in advance. In the united States, the current requirement is to sign up by the 34th week of pregnancy. This cannot be over-stressed; time and time again, mothers who want to donate are turned away because they did not inquire about donation until it was too late.
Founded in 1992, CBR has stored more than 600,000 cord blood and cord tissue collections from 3,500 hospitals in over 100 countries and partnered with institutions to establish multiple FDA-regulated clinical trials. 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.

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.
Only 25-50% of donations to public cord blood banks end up being stored.4 Typically, public cord blood banks only store donations that meet the size threshold for transplant use. That means most public cord blood banks will only keep cord blood collections that are at least 3 ounces.2
Your baby isn’t the only one who may benefit from having access to preserved newborn stem cells. The cells can potentially be used by siblings and parents, too. In many cord blood treatments, stem cells from a matched family member are preferred.
Cord blood banking is not always cheap. It’s completely free to donate blood to a public cord blood bank, but private banks charge $1,400 to $2,300 for collecting, testing, and registering, plus an annual $95 to $125 storing fee.
The umbilical cord is a rich source of two main types of stem cells: cord blood stem cells and cord tissue stem cells. Through the science of cord blood and cord tissue banking, these stem cells can help nurture life, long after your baby’s birth.

I am currently 38 years old and I would like to have my blood and it’s stem cells harvested via peripheral blood draw to be stored in definitely. Do you offer this service? If so, how can I arrange for my family?
Students who register to donate blood three or more times during their high school career earn a Red Cord to wear during graduation events. Seniors must complete the requirement by May 15 (or by the date of their school’s final blood drive of the year, whichever is later).
Cord blood is used to treat children with cancerous blood disorders such as leukaemia, or genetic blood diseases like Fanconi anaemia. The cord blood is transplanted into the patient, where the HSCs can make new, healthy blood cells to replace those damaged by the patient’s disease or by a medical treatment such as chemotherapy for cancer.
