Cord Blood Stem Cell Banking INFORMATION FOR HEALTHCARE PROFESSIONALS
Today, parents and expectant mothers and fathers, have access to more information about child healthcare than probably any other generation in history. They ask their doctors, nurses, midwives, obstetricians and paediatricians, more questions, and demand more answers. And one of these questions concerns collecting and preserving their baby's cord blood stem cells.
This booklet is designed to help, by providing you with at least some of the information you will need. It will explain what stem cells are, and what their clinical applications are. It will also detail the accreditations and licences required by organizations in the UK to perform the storage and preservation of stem cells, plus itemize which accreditations are held by Future Health Technologies.

What are stem cells? Stem cells are the body's very early unspecialized "master" cells. They have two distinct characteristics: â€˘ They can self-renew through cell division for the duration of our life. â€˘ They have the remarkable potential to develop into other types of cells and tissue, such as red or white blood cells, nerve cells, brain cells or even the cells of the heart. Therefore they serve as a repair system for the body, continuously replenishing other cells. Umbilical cord blood is a rich source of haematopoetic progenitor cells (HPCs) as well as multipotent stem cells called multilineage progenitor cells MLPCs1. More specifically cord blood stem cells include mesenchymal stem cells (MSCs)2 and dendritic cells3,4,5. In fact, cord blood has a significantly higher concentration per volume of primitive HPCs than bone marrow 6,7, thereby making it a good source of cells for transplantation8.
When can cord blood stem cells be collected? Stem cells from peripheral blood and bone marrow can be collected at any time. But the procedure for bone marrow collection can be painful and finding a perfect or ideal match could be problematic. Cord blood stem cells, on the other hand, can only be collected at birth. Unfortunately, this precious blood is routinely discarded at birth by the hospital.
When was cord blood treatment first performed? The first cord blood transplant was performed in the 1960's. The first successful cord blood transplant was performed in 1988 by Dr E Gluckman on a 5 year old boy with Fanconi Anaemia. He was given a 0% chance of survival 9. The donor was his HLA-identical newborn sister who was known by pre-natal diagnosis to be HLA identical and not affected by the Fanconi mutation. The cord blood was collected during her birth and was then processed and cryopreserved. The transplant was successful without Graft versus Host Disease (GvHD), and the patient is currently alive and free of disease more than 20 years after transplant, with full haematologic and immunologic reconstitution. At the time of the first successful transplant, little was known about the biologic properties of cord blood cells and it was thanks to the pioneering work of H. E. Broxmeyer and E. A. Boyse, who studied the progenitor cell content of cord blood, and of A. D. Auerbach, who realised the pre-natal diagnosis of Fanconi Anaemia, that this transplant was possible.
How widespread is the treatment? In the years following that first successful procedure, the number of transplants of HPCs derived from cord blood has steadily increased. Transplants take place - and diseases are treated in children and adults - all over the world. Dr E. Gluckman announced in May 2006 at the International Society for Cellular Therapy conference in Berlin that over 10.000 cord blood stem cell transplants have already been performed10. In June 2008 at the Cord Blood Transplantation Symposium in Los Angeles California, Dr E. Gluckman reported that over 14,000 cord blood transplants have been formally recorded worldwide, but actual numbers are probably closer to 20,000.
What conditions are stem cells used to treat? Numerous reports document the feasibility and efficacy of the transplantation of cord blood stem cells for the treatment of a broad range of disorders, including haematological malignancies, solid tumours, constitutional and acquired bone marrow failure syndromes, haemoglobinopathies, congenital immune deficiencies, and inherited disorders of metabolism11,12,13. When properly processed and tested, cord blood stem cells may be used by the entire family; they may be used by the child from which they were collected (autologous use) as well as his/her brothers and sisters and possibly the parents (related allogeneic use) themselves. All properly accredited cord blood stem cell banks perform full testing of the samples. 07
Here’s what various studies indicate about specific conditions: Chronic Myeloid Leukaemia (CML)
“Autologous haematopoietic stem cell transplantation (autoHSCT) is a widely used form of treatment for haematological malignancies, including chronic myeloid leukaemia (CML)” D. S. Krause, Massachussetts General Hospital, Boston, MA14. Multiple Myeloma
A study on 508 patients with multiple myeloma undergoing autologous stem cell transplantation confirmed that high doses of autologous CD34+ cells shorten haematopoietic reconstitution and reduced hospitalisation15. Lymphoid Malignancies
Autologous stem cell transplantation is used in patients with lymphoid malignancies including Hodgkin's disease, non-Hodgkin's lymphoma or Multiple Myeloma16. Neuroblastoma
Autologous stem cell transplantation is used in children with high-risk Neuroblastoma17.
Autologous transplants Allogeneic transplants

Chart 2: Related v Unrelated Allogeneic Hematopoietic Stem Cell Transplants 2003 - worldwide
Transplant data for all types of stem cell transplantations performed is collected by CIBMTR (Center for International Blood & Marrow Transplant Research). The data demonstrate that the majority of transplants are autologous.In North America out of the 16900 transplants in the statistics for the year 2003, 9600 (56.8%) were autologous. Of the allogeneic transplants, again the majority are related transplants. Worldwide, out of 13700 transplants in the statistics for the year 2003, 8800 (64.2%) were related (i.e. the samples came from a relative of the patient, not from an unrelated person). Therefore, only a small percentage of the total number of transplants come from an unrelated person. The majority of the transplants are either autologous or from a relative of the transplant recipient. The data was given by the Statistical Center of the Center for International Blood and Marrow Transplant Research (CIBMTR). www.cibmtr.org. The site states that: "The CIBMTR unites and builds on the strengths of two leaders in the field of blood and marrow transplantation, the International Bone Marrow Transplant Registry and the Autologous Blood and Marrow Transplant Registry (IBMTR/ABMTR), and National Marrow Donor Program (NMDP)" A list of conditions for which stem cell transplantation is used worldwide follows. More conditions will be added to the list as time goes by. It should be noted that stem cells are not normally used to treat genetic disorders on the child from which the sample was collected. In this case a sample collected from a sibling is the best option. One major benefit of cord blood is the reduced capacity of cord blood cells to produce an alloreactive response (i.e., an immune response against the recipient). This results in markedly less frequent and less severe graft versus host disease (GvHD)18. Cord blood stem cells are a perfect match for the baby and carry a significant probability of match in other family members, with the probability of an exact match for a sibling being 25%19. "Studies consistently demonstrate that umbilical cord blood (UCB) is an effective alternative source of haematopoietic stem cells (HSC) for adult transplantation with at least comparable results to other HSC sources for adult patients."

What conditions could be treated in the future? Exciting developments in the research of treatments appear almost daily in the media, announcing the potential of stem cells to treat a variety of diseases, including Multiple Sclerosis20, Type 1 Diabetes21, Testicular Cancer22,Liver Cancer and to regenerate the heart following a Myocardial infarction23,24. Studies demonstrate the use of cord blood stem cells for cardiac regeneration38,39,40,41. The UK government has already funded a lot of this research and announced in the 2005 Budget a £2.5 Billion investment over the next 10 years.
As Dr. E. Gluckman indicated at the International Society for Cellular Therapy Conference in Berlin in May 2006, “there are “ES-equivalent stem cells”, or “unrestricted somatic cells”, in cord blood that can differentiate into osteoblasts, chondroblasts, adipocytes, hepatocytes and neural cells in a homogeneous fashion in various animal models. It is also claimed that this cell population, although rare in cord blood, can be expanded to give a very large number of cells without losing pluripotency. In conclusion, cord blood is a unique biological resource for haematopoietic transplantation, regenerative medicine and scientific research10.”
Umbilical cord blood MLPCs is a “new and powerful tool in tissue engineering and the development of more effective ECM scaffolds26.”
“Autologous stem cell transplantation could be a safe and valuable method for restoration of neurological function in stroke patients27.”
“Mounting evidence for the concept that umbilical cord blood may serve as a convenient source of neuronal progenitors28.”
Dendritic Cells are a promising tool of immunotherapy for cancers “We were able to produce enough amount of matured Dendritic Cells for clinical use and this study provides noteworthy results of generating a large number of functional DCs using CD34+ progenitor cells obtained from umbilical cord blood3.”
“High-dose chemotherapy with autologous stem cell transplantation appears to be an effective treatment for MS both in terms of clinical and patientreported outcomes29.”
Studies have indicated that:
Multi-Lineage Progenitor Cells (MLPCs) found in cord blood can be differentiated into respiratory epithelial cells25.
Who preserves cord blood stem cells?
What reasons are there for storing cord blood?
Following the first successful transplant, the importance of cord blood stem cells in medical treatments became recognized among doctors and their storage for future use became a pressing need. In 1992, a doctor of biochemistry, David Harris, set the foundations for the establishment of the first private cord blood bank when he decided to preserve the cord blood stem cells of his newborn son. Since that date, it is estimated that over a million parents worldwide have chosen to store their child's cord blood in a private facility.
Many factors affect the parents' decision to bank their child's cord blood. Of course the obvious one is that parents see cord blood stem cells as a valuable resource for the future. They see the research findings published to date and firmly believe that the potential applications may be of benefit to their baby or other biological family members in the future. In other words…they believe it's better to have it and maybe not need it, than to need it and not have it!
The first NHS cord blood bank was set up in the UK in 1996 by the National Blood Service and to date have collected and cryopreserved over 10,000 donated samples. This is based on altruistic cord blood donation, where donor cord blood is kept in a 'pool' for anyone to use. Altruistic cord blood donation is still only available in 4 hospitals in the UK 30, 31 so the opportunity to donate is limited. "Collection and freezing of cord blood units should be considered strongly in families with a child affected with haemoglobinopathy or other genetic diseases." Royal College of Obstetricians and Gynaecologists Scientific Advisory Committee, Opinion Paper 2, Revised June 2006.
However, there are circumstances where storing cord blood stem cells is more than simply 'insurance'. Where there are real medical considerations. For instance: • If there is a family history of one or more of the diseases that use stem cells as a treatment. • If the parents are from a mixed race background. Research has shown that finding a match for this group is very difficult. • If a baby is born as the result of IVF treatment using donor egg/sperm, it is more difficult to trace prospective donors, should the need arise.
How easy is it to collect umbilical cord blood? â€œBanking of cord blood has developed to supplement bone marrow stem cell transplantation. Placental umbilical cord blood can be used as an alternative to bone marrow or peripheral blood cells to treat life-threatening disorders of children and adults. Cord blood is collected at no risk to the donor, is less likely than adult bone marrow donations to carry viral infections, brings to the recipient a lower incidence and severity of acute and chronic graft-versus-host-disease.â€? Sue Armitage et al.:Cord Blood donation, testing and banking: A guide for midwives, British Journal of Midwifery, Vol. 14,(1): 6 - 9, 05 Jan 2006.
It's not only easy, it's also non-invasive and risk-free to baby and mother. What's more, it's a procedure that's performed routinely by obstetricians, midwives and nurses in many hospital delivery rooms all over the world, where the newborn is jaundiced or the mother's blood group is Rh negative or for blood typing. You may even be familiar with collecting cord blood yourself. However, there is a protocol that should never, under any circumstances be deviated from. The first priority of any Healthcare Professional in a birthing situation is the health of the mother. Second, the health of the baby. Then, and only then, the collection, if requested, of the baby's cord blood. Many parents who choose to collect and save their babies cord blood will approach their midwife and ask for help and guidance. They will not only ask about the procedure, they will also ask about how their baby's cord blood stem cells will be storedâ€Śand who will store them. Many parents will have already 'done their homework'. They may have contacted a number of cord blood storage facilities. They might already know as much as you do about the procedure.
Who is Future Health? We were the FIRST private family cord blood bank in the UK to receive a full accreditation as a human tissue bank (accreditation awarded in 2004 by the UK's Medicines & Healthcare products Regulatory Agency (MHRA) of the DoH (0083/00/00/0-04)). On April 7th 2006, we received a deemed licence from the Human Tissue Authority (HTA), according to the new EU Tissues and Cells Directives (2004-2006). On 1st September 2006 we were again, the FIRST private tissue bank to receive a 3 year substantive licence from the HTA. The Human Tissue Authority (HTA) regulates the processing and storage of human tissue, for a number of Scheduled Purposes set out within the Human Tissue Act. As part of their regulatory function, the Authority carries out inspections of licensed establishments, making sure that certain activities are only carried out under the authority of a licence granted by them. At the end of 2007 we completed the construction of our new labs. The Human Tissue Authority (HTA) inspected the new labs as well as the rest of the facilities and renewed our licence for a further 3 years, Licence 22503 02-04-08. This means that everything, from our collection methodology, through to our laboratory processes and storage facilities, has been rigorously inspected and fully approved. Our own purpose built laboratory strictly adheres to the guidelines of the Code of Practice for Human Tissue Banks, the guidance on the Microbiological Safety of Human Organs, Tissues and Cells used in Transplantation and current Good Manufacturing Practice (cGMP). We also adhere to all current EU directives. We use the very latest processing and cryopreservation equipment, and operate under the very highest security and monitoring protocols. For instance, we require that the collection be made only by a Healthcare Professional, and transported by approved medical couriers in thermal shipping boxes, for protection against adverse temperature conditions. Future Health is based in Nottingham UK, where we have our own purpose-built laboratories, on-site storage facility and administrative offices. We have already collected samples from over 35 countries in the world. We have offices in over 15 countries around the world. Our network of offices is rapidly expanding in order to meet the local needs in each country and culture. Being an accredited facility brings peace of mind and valued reassurance not only to parents, but also to Healthcare Professionals. What does it mean to have a licence as a Human Tissue Bank? • Not a simple laboratory licence. We can legally handle human tissues and cells • We can legally transport human cells (biological material) within and across countries according to EU Directives • Samples can be used by: 1. Donor / child (autologous use) 2. Any family member or other person (allogeneic / heterologous use) • The sample is legally accepted from all the hospitals and transplantation centres as an injectible substance.
The HTA is now the Competent Authority in the UK under the new EU Tissues and Cells Directive, with responsibility for licensing the storage of human tissues and cells, including haemopoietic stem cells. (EUTCD Commission Directive 2006/86/EC, 24 October 2006, 2006/17/EC, 8 February 2006. Directive 2004/23/EC, 31 March 2004).
Cord blood collection kit All necessary equipment for the collection is included in the kit that the parents will bring with them to the delivery room. The kit contains a purpose-designed cord blood collection bag, enclosed in an individual sterile package, with two needles for ease of collection and to reduce the possibility of contamination. The bag contains the correct amount and type of anticoagulant for cord blood preservation. In addition, the cord blood must be collected using Aseptic Technique to prevent contamination of the sample. The sample is transferred in special isothermic packaging designed by Future Health, which is accredited (BVI C-07.004) according to the regulations concerning the safety of transportation of biological substances (UN 3373, IATA PACKING INSTRUCTION 650).
Advanced cryopreservation facility Stem cell separation and preservation are carried out by specialised, scientific laboratory personnel - in accordance with strict guidelines, in line with our MHRA accreditation and HTA licence. The samples are processed in sterile, Grade B clean rooms with Grade A laminar flow work areas, in a positive pressure controlled atmosphere. The air within the controlled area passes through hepa filters and is continuously renewed. The entrance from the Grade C lab area to the Grade B clean rooms is through double pressure doors, accessed only by lab technicians, who wear sterile full body suits, completely covering the entire body from head to toe. Room sterility is continuously monitored by the use of agar plates, the testing of which is performed by the Nottingham University Hospitals Trust, as an additional precaution. These strict conditions of sterility are superior even to a hospital operating theatre. This is a measure of assurance above and beyond the requirements of the UK Department of Health. Cord blood stem cell samples are placed in special, laminated cryobags, which is a vital part of our closed processing system. This prevents any contact with atmospheric air. They are not placed in vials, as these have been known to cause problems in long term sample cryostorage. The cryobag consists of two, independent chambers, permitting the multiple future use of each sample. This bag is then bar coded with a metallic label, to ensure the positive identification of each sample, then sealed and placed in an external protective bag. The double-bagged sample is then placed in a metal canister for additional protection against possible mechanical damage. The metal canisters are then bar coded with the same unique number as the cryobags. They're then stored in the vapour phase of liquid nitrogen in automated cryostorage tanks as opposed to being immersed in liquid nitrogen. This prevents the possibility of cross contamination between samples in the liquid phase. Storage temperature is controlled and monitored on a 24 hours basis. In the remote case of a prolonged power failure or malfunction of the automatic system, the tanks are designed to be operated manually for indefinite periods of time, ensuring in every case the proper long term cryopreservation of the samples. Our facility has 24/7 recording of storage condition parameters and 24/7 security systems and security personnel on site. Future Health specialises only in processing and storing cord blood stem cells. All client information is handled according to the UK Data Protection Act.
Facts and misconceptions Misconception: All cord blood stem cell banks are fully accredited and fully licensed to the highest standards. FACT: That's not the case. Future Health is the first family cord blood stem cell bank in the UK to be accredited by the Medicines and Healthcare Products Regulatory Agency and fully licensed by the UK Human Tissue Authority - according to the new EU Tissue and Cells Directives (2004-2006).
Misconception: Preserving and banking cord blood is not justifiable, as the probability of a family ever needing to use it is extremely low. FACT: New data published in March 200832 indicates the probability of an individual in the United States needing a stem cell transplant, using either one's own stem cells or those from a donor, is much higher than previously stated. This new research says that as many as 1 in 200 people will receive a stem cell transplant during their lifetime, based on current therapeutic use of hematopoietic stem cells. These outcomes stand in stark contrast to previous estimates that suggested a much lower probability.
Misconception: The Healthcare Professional who collects the cord blood, will be held responsible and liable if, for any reason, the cord blood isn't collected, or not enough blood is collected. FACT: Any parent who asks their Healthcare Professional to collect cord blood for storage with Future Health, signs a legal disclaimer form. This legally exempts the Healthcare Professional from any responsibility, should the sample not be collected or should anything go wrong. They would have our full support on any such issue.
Misconception: A person will never be able to receive an autologous cord blood transplant because it would have the traits of the disease. FACT: Autologous stem cell transplants have been routinely performed throughout the world to treat haematological disorders and various solid tumours 4,14-17,24. Stem cells in cord blood should be normal and free of malignancy, giving them a potential advantage over autologous cells collected during haematological remission from a patient with malignancy32. According to a new study published recently37 the lifetime probability that an individual will undergo a stem cell transplant with his own stem cells for treatment is 1:435. Cord blood may also be used by the siblings or parents when there is sufficient compatibility. It is always up to the doctor to decide but cord blood may even be used when there are cases where there is a four out of six HLA type compatibility.
Misconception: When cord blood is stored for the family in a private facility, it deprives the NHS of a potentially donated sample. FACT: Every year, more than 99% of the potential cord blood samples from over 700,000 births in the UK are discarded. There are potentially far more samples available than the National Blood Service could possibly store. What's more, donating cord blood is available in only 4 hospitals in the UK30. Recent reports suggest that only 30% of donated cord blood is actually kept, due to various factors related to the donors. Most parents do not have the option of donating their cord blood, and many feel that this resource is too valuable to simply be thrown away.
Misconception: Cord blood stem cells have only been used experimentally. FACT: Since the first successful cord blood transplant in Paris in 1988, more than 10,000 cord blood transplants have taken place as part of standard medical treatments worldwide10. In June 2008 at the Cord Blood Transplantation Symposium in Los Angeles California, Dr E. Gluckman reported that over 14,000 cord blood transplants have been formally recorded worldwide, but actual numbers are probably closer to 20,000.
Facts and misconceptions Misconception: Privately stored cord blood stem cells may only be used by the child from whom they were collected. FACT: Cord blood stem cells are 100% compatible with the person from which they were collected from. However, they may also be used by the parents and siblings of the child since there is a significant possibility of histocompatibility among family members. The allogeneic use of a sample is only allowed if the sample was processed and stored in a fully licensed bank such as Future Health. This increases both the scope and the chances of use of the sample. If a sample is stored in a bank that does not have a Human Tissue Bank licence then it can only be given back to the donor (autologous use only).
Misconception: Cord blood stem cells can be used in children but not adults. FACT: â€œStudies consistently demonstrate that umbilical cord blood (UCB) is an effective alternative source of haematopoietic stem cells (HSC) for adult transplantation with at least comparable results to other HSC sources for adult patients36.â€? The first adult transplantation in the UK was carried out in 2002 in Newcastle.
