A successful blood stem cell transplantation can potentially cure patients of some diseases by replacing their blood stem cells. Diseases most commonly treated by transplantation include diseases of the blood such as cancers or red blood cell disorders , bone marrow failure diseases, and certain immunodeficiencies diseases that result from missing or dysfunctional immune cells.
Less commonly treated by transplantation are inherited metabolic diseases deficiencies in breaking down substances in the body. A list of diseases that can be treated by blood stem cell transplantation is available on Be the Match , the largest international registry of blood stem cells.
Additional information on blood stem cell transplantation is available from the National Institute of Health. Be aware that many predatory clinics offer treatments using cord blood cells, or cells derived from the placenta or amnion, that are not supported by the current understanding of science and blood stem cell biology.
While these stem cell clinics may advertise the use of blood stem cell transplantation for a variety of diseases, many of these treatments have not been proven to be safe or effective. Finding your match. Blood stem cells used for a transplant can either come from yourself or from someone else. If the patient has a blood cancer or another genetic blood disease, their stem cells may also be diseased and therefore cannot be used in their own transplant. If a donor is needed, they must be a good immunological match with the patient.
Private banking vs. Public donation After cord blood is collected it can be banked, frozen at very low temperatures and stored, for future use see figure at right. In , the American Academy of Pediatrics reported that there are about , units of cord blood stored at public banks, and over 5 million units banked for private use worldwide.
Even though there are over 6 times as many units stored in private banks, public banks have released about 30 times more units for therapeutic use. Families storing cord blood should seek facilities that have been accredited by reputable organizations. Foundation for the Accreditation of Cellular Therapies FACT sets international standards and accredits cord blood banks and cell transplantation programs. This upfront fee often also includes the price of the kit provided to collect and safely transport the cord blood, the medical courier service used to expedite the kit's safe shipment, the testing of the mother's blood for any infectious diseases, the testing of the baby's blood for any contamination, and the cost of the first full year of storage.
We offer special discounts and offers for multiple births, returning customers, referrals, military families, medical professionals, long-term, pre-paid storage plans and more. See how much cord blood banking costs at Cryo-Cell here. While banking cord blood is a new experience for many parents, it is a simple one. Thankfully, the healthcare provider and the cord blood bank do most of the work.
Here are the steps found in cord blood banking:. This is a simplified version of the steps to cord blood banking.
For a more detailed overview, you can read more about the steps to cord blood banking here. When the medical courier delivers the cord blood collection kit to the cord blood bank, it is quickly processed to ensure the continued viability of the stem cells and immune system cells found in the cord blood. As these tests are being conducted, the cord blood is processed to reduce the number of red blood cells and its total volume and isolate the stem cells and immune cells.
There are a number of different processing methods out there for a cord blood bank to use, and the processing method can ultimately affect the purity of the final product, which we'll explain in a minute.
Once the stem and immune system cells have been isolated and extracted from the plasma and red blood cell, they are mixed with a cryo-protectant and stored in a cryo-bag. We over-wrap our bags for added protection and use a technique called "controlled-rate freezing" to prepare the cells for long-term storage. The over-wrapped cryo-bag is housed in a protective metal cassette and placed in vapor-phase liquid nitrogen freezer for long-term preservation. As noted, there are different ways to process cord blood, and although the type of processing method doesn't always enter the conversation on cord blood banking, it is a big part of the purity of any cord blood collection.
Red blood cells can have a negative impact on a cord blood transfusion. In addition, there is a certain number of stem cells that need to be present in order for the cord blood to be effective in disease treatment. Each processing method has the ability to better reduce the number of RBCs and capture more stem cells. Some processing methods like AutoXpress and Sepax are automated to ensure a level of consistency across all collections.
HES is preferred by some banks because it was the original processing method used by most banks and it has a proven track record. You can read more about the different cord blood processing methods here. In terms of performance, our PrepaCyte-CB processing method has taken the lead. PrepaCyte-CB greatly improves on parents' returns on investment because it yields the highest number of stem cells while showing the greatest reduction in red blood cells.
The ability to get better more quickly and a reduced chance of infection can prove vital in certain cases. Today, many conscientious parents are also considering delayed cord clamping DCC , a practice in which the umbilical cord is not clamped immediately but rather after it continues to pulse for an average of 30 seconds to seconds.
As noted early, our premium processing method, PrepaCyte-CB, is able to capture more immune system cells and reduce the greatest number of red blood cell contaminants. This makes it go hand in hand with delayed cord clamping because it is not as affected by volume, effectively making up for the smaller quantity with a superior quality.
You can read more about delayed cord clamping vs. Banked cord blood is most abundant in white blood cells and stem cells. While a lot of attention is paid to the stem cells, there are approximately 10 times more total nucleated cells TNCs than stem cells in any cord blood collection.
TNCs are basically white blood cells, or leukocytes; they are the cells of the immune system that protect the body. Despite stem cells comprising one-tenth of most collections, cord blood is still considered a rich source of hematopoietic he-mah-toe-po-ee-tic stem cells HSCs. Google Scholar.
