The establishment of a national tissue bank for inflammatory bowel disease research in Canada.

The Crohn's and Colitis Foundation of Canada (CCFC) has established a national bank for tissue, serum and blood from patients with inflammatory bowel disease (IBD). Investigators from across the country submit material to the bank together with clinical data. Investigators may access their own patient information from the bank for their own study purposes, but the distribution of tissue is restricted to specific CCFC-funded projects. Currently, tissues are being collected from newly diagnosed, untreated IBD patients to support a recent initiative aimed at characterizing microbes in colonic and ileal biopsies from such patients. In the future, criteria for the submission of tissue will be tailored to specific research questions. This bank is believed to be the first national bank of its kind dedicated to research in Crohn's disease and ulcerative colitis

Microbiological monitoring of bone grafts: two years' experience at a tissue bank.

In the first two years of operation of a tissue bank, bone was processed on 63 occasions from 22 cadaveric donors and on 37 occasions from 185 living donors. A standardized protocol for microbiological sampling, culturing and interpretation of the results was developed. Semi-quantitative culture of washings of bone was performed on receipt by the tissue bank, and broth enrichment cultures of bone samples were performed at the end of processing, and again after irradiation. One bone donation was rejected because of heavy contamination with Klebsiella sp. on receipt, and contamination of six donations with Burkholderia cepacia was shown to have come from a water deionizer. Contamination of bone on receipt by the tissue bank decreased during the study period, probably related to increasing experience of staff harvesting bone. Microbiological surveillance of bone grafts protect recipients from infection, and is useful as a quality control of the process of bone banking.

Navigating tissue banking regulation: conceptual frameworks for researchers, administrators, regulators and policy-makers.

In the "post-genomic" age of biomedical research, researchers often wish to utilise collections of human tissue. This type of research raises many ethical and legal issues and anyone wishing to use such collections is faced with an enormously complex set of regulatory requirements, many of which are still ambiguous, reflecting ongoing ethical and legal debate. Whilst there is no way of entirely avoiding such regulatory complexity and ambiguity, conceptual frameworks can assist those who wish to use, administer, authorise and generate policy on tissue banking research. Two conceptual frameworks are described here: a taxonomy of tissue banking practices, aimed at assisting those who need to ensure that tissue banks meet ethical and legal requirements; and a "syncretic" approach to policy-making, for those who wish to generate new policy, or streamline existing policy relating to tissue banking research.

Equipment and organization of a frozen tissue bank--an update.

The growth of molecular diagnostics and its application in various clinical laboratories has made it necessary to standardize the methods used to freeze and store tissues used in molecular testing. It may now be advantageous to preserve fresh tissues and other specimen types in a central frozen tissue bank so that sample preparation and storage conditions are appropriate for molecular applications and so that the specimen inventory can be efficiently managed. The pathology laboratory is a logical site for this facility since the professional and technical expertise available is focused on the complex scientific and managerial aspects of laboratory medicine. Organizationally, the tissue bank program should be overseen by a surgical pathologist in order to integrate it into routine surgical pathology activities. A member of the laboratory technical staff can serve as the tissue bank coordinator with responsibility for systematic storage and retrieval of specimens and routine maintenance of equipment and supplies. In order to facilitate the tissue freezing procedure as well as efficient storage of multiple types of specimens, 2.0 ml cryogenic vials are used as the uniform storage container. All specimens are stored at -140 to -150 degrees C in the vapor phase of liquid nitrogen. The specimen inventory data are maintained with a computerized program specifically designed to manage complex specimen storage. A frozen tissue bank is easily implemented in a pathology laboratory and is a valuable institutional asset for diagnostic and research purposes.

Tissue banking in Mexico.

INTRODUCTION: Here, we describe our Tissue Banking experiences of 4 years of activity in Mexico. METHODS: Data of allografts provided by our Bank and bone retrievals performed by our teams between February of 2001 and August of 2004 were included. RESULTS: There were 100 bone donors, a total of 1,107 tissues were obtained with an average of 11 tissues by retrieval, samples from all tissues were obtained during retrieval and cultured for bacterial contamination, 250 tissues were positives to bacterial growth with an average of 22.58% of bacterial contamination of tissue by retrieval. A total of 4,493 allografts were provided and were utilized in 3,643 patients. The allografts were used mainly by orthopedic surgeons (62%) and dentists (30%). The most used allografts were morcellized cancellous bone 31%, pulverized 25% and chips of cancellous bone 20%. Among orthopedic patients the most frequent procedures were related with spine degenerative diseases 39.09%, followed by non-pathological fractures and its complications 28.67% and bone tumors and cystic bone lesions 11.59%. CONCLUSIONS: Sustained increase of allograft utilization in Mexico reflects a great necessity for them in our country. The increase in public awareness about tissue donation has allowed an increase in tissue donations and retrievals.

Ovarian tissue banking for cancer patients: reduction of post-transplantation ischaemic injury: intact ovary freezing and transplantation.

Despite reasonable achievements in different animal species, the debate about many technical aspects of ovarian tissue banking is continuing. Human ovarian tissue banks are increasingly established around the world without a clear plan about how to make the best use of such tissue. One of the important challenges facing this growing technology is to determine the ideal method for the use of this cryopreserved ovarian tissue. It is not uncommon in medicine to introduce a technology without a clear understanding of the consequences. If it is decided that ovarian tissue is to be autotransplanted, what is the most suitable place? Which technique should be implemented? As a part of the ongoing debate on ovarian tissue banking in cancer patients, this paper supports the notion that cryopreservation of an intact ovary with its vascular pedicle may be a viable alternative to the currently available techniques. Research in the development of technology to cryopreserve whole organs as well surgical techniques for the auto-transplantation of an ovary with its vascular pedicle should be encouraged.

Fourth meeting of the European Network of Research Tissue Banks - future strategy to increase collaborations in the supply of human tissue for biomedical research.

This report records the Fourth meeting of the European Network of Research Tissue Bank (Brussels, 18th March 2004) which was attended by Mel Read MEP. The existing membership of this informal group represents European Human Research Tissue Bankers, biomedical researchers seeking access to human tissue and allied groups including animal welfare representatives. This Fourth meeting provided a forum to update members on individual activity in this area. A particular focus of this meeting was to consider the status of this group and future affiliations to increase the profile and activity of this Network. This meeting addressed differences in legislative and ethical requirements governing the use of human tissue in biomedical research in the different countries represented. Future activity of the ENRTB, planned at this meeting, will target harmonisation of current differences which are currently barriers to increased access to human tissue for biomedical research. Through the harmonisation of procurement, processing and distribution of human tissue specimens the ENRTB will provide a mechanism to benefit human health through increased use of human tissue in pharmacotoxicological studies and the associated replacement of animal tests.

Tissue banking: the role of the Regional Blood Centre: an American experience in Minnesota.

The clinical use of bone, cornea, skin, connective tissue and heart valve allografts has increased greatly in the past several years, with bone the most commonly transplanted tissue. Tissue allografts have been the vehicle to transmit infectious disease from donor to recipient. Provision of safe and effective tissue has gradually developed and improved as regional tissue banks have organized, and standards of practice evolved. Regional Blood Centres have the special capabilities and experience to provide the expertise required in tissue banking. Consequent to these community needs, regional bone and tissue banks have been established in blood banks and the experience of the American Red Cross in St Paul, Minnesota is described.

[Organization of a bone and tissue bank].

The regional bone bank offers a good foundation for covering the expanding clinical demands in tumor and revision surgery. Since 1980 the tissue bank of Münster consists of 32 cadaveric and 41 multi organ donors. In the guidelines of the tissue bank the responsibility, organisation form, donor selection, quality control, sterilisation, documentation and all questions of finances are fixed, in accordance to the American Association of Tissue Banks. A fixed staff will be helpful to offer a secure and not expensive donor tissue for the clinical demands.

Supply and use of human tissue for research purposes: survey of BATB affiliated tissue banks.

This paper describes a survey undertaken to identify the extent of supply and use of human tissue in research by BATB affiliated tissue banks. Approximately one third of tissue banks registered with the BATB are currently supplying samples that are found to be unsuitable for clinical use, for research. These banks all obtain consent for research and all supply tissue for in-house research. Some tissue is transferred to other public and commercial institutions. A harmonised network approach is proposed as the way forward to meet the increasing demand for human tissue in research.

Ethical issues in tissue banking for research: a brief review of existing organizational policies.

Based on a general review of international, representative tissue banking policies that were described in the medical, ethics, and legal literature, this paper reviews the range of standards, both conceptually and in existing regulations, relevant to four main factors: (1) commercialization, (2) confidentiality, (3) informed consent, and (4) quality of research. These four factors were selected as reflective of some of the major ethical considerations that arise in the conduct of tissue banking research. The authors emphasize that any policy or ethical guidelines designed to regulate tissue bank research should address all four factors. Whenever this sort of research is conducted between several institutions or several countries, the paper suggests that the relevant entities work collaboratively to harmonize their standards.

[Tissue bank for the musculoskeletal system. Clinical applications].

From June 1987 to June 1990, the musculoskeletal system tissues bank of the Orthopaedics and Traumatology Department of the University Clinic of Navarra has used 310 allografts. Of this, 219 has been used in our Department, 142 of cancellous bone and 42 of cortical bone. 24 of patellar tendon and 11 of fascia lata. The other 91 grafts have been sent to other hospitals in the country. In the present work we make a retrospective study that included the patients who were operate with allograft. We observe the differences between several types of allografts comparing them with conventional surgery technics. Within the complications we distinguished a 10.52% of infection in cortical bone allografts used in patients with neoplastic treatment. In the other type of allograft we didn't present this complication. We concluded that a bone bank or a musculoskeletal system tissues bank has a great usefulness in different reconstructive surgery technics and arthrodesis. They are used more frequent in orthopaedics and traumatology surgery improving the development of this surgery.

Vascular tissue banking: state of the art.

INTRODUCTION: The cardiovascular homograft banks in Italy were set up in 1994 in Milan (Lombardia) and Treviso (Veneto) and in 2001 in Bologna, Emilia Romagna. In this study we briefly summarize the data from Emilia Romagna Cardiovascular Tissue Bank. MATERIAL AND METHODS: In Emilia Romagna, vascular homografts were harvested from brain-dead multiorgan donors (aged 15-55 years) by a dedicated vascular surgery team. All donors were virologically screened for human immunodeficiency virus (HIV), hepatitis B and C, Treponema pallidum, cytomegalovirus (CMV), and Toxoplasma. After transferring the vascular homografts to Emilia Romagna Cardiovascular Tissue Bank facilities, the arteries were prepared, classified (class III to I), and transferred to an antibiotic-containing solution under a laminar flow cabinet. After the decontamination, all homografts were cryopreserved and stored in the vapour phase of liquid nitrogen. Microbiological tests were performed in all phases of preparation. Samples were routinely taken from 1 vessel and formalin fixed for the histology. Bags with cryopreserved homografts were sent in dry ice to the hospitals when required and thawing protocol of the Bank was included. RESULTS AND CONCLUSIONS: From January 2002 to October 2004, 543 homografts from 125 heart-beating donors were harvested and transferred to Emilia Romagna Cardiovascular Tissue Bank. After preparation, 459 of 543 (85%) were cryopreserved and stored. Vascular homografts classified class I were discarded. Other criteria of rejection were: (1) positive serology, and (2) persistent positive microbiology after decontamination. From March 2002, 333 cryopreserved homografts were assigned to several vascular surgery departments in Italy. The assessment of 3-year activity of Emilia Romagna Cardiovascular Tissue Bank might be used as an indicator of the efficiency of selecting, cryopreserving, and allocating quality-controlled vascular homografts.

TuBaFrost: European virtual tumor tissue banking.

TuBaFrost is a consortium responsible for the task to create a virtual European human frozen tumor tissue bank, composed of high quality frozen tumor tissue collections with corresponding accurate diagnosis stored in European cancer centers and universities, searchable on the Internet, providing rules for access and use and a code of conduct to comply with the various legal and ethical regulations in European countries. Such infrastructure would enlarge tissue availability and accessibility in large amounts of specified or even rare tumor samples. Design of an infrastructure for European residual tissue banking with the described characteristics, clear focus points emerge that can be broken down in dedicated subjects: (1) standardization and quality assurance (QA) to avoid inter-institute quality variation; (2) law and ethics enabling exchange of tissue samples possible between institutes in the different European countries, where law and ethics are characterized by a strong variability; (3) rules for access, with sufficient incentives for collectors; (4) central database application containing innovations on search and selection procedures; (5) support when needed with histology images; and (6) Internet access to search and upload, with in addition a solid website giving proper information on the procedures, intentions and activities not only to the scientific community, but also to the general public. One consortium decision, part of the incentives for collectors, had major impact on the infrastructure; custodianship over the tissues as well as the tissues stay with the collector institute. Resulting in specimens that are not given to an organization, taking decisions on participation of requests, but instead the local collected tissues stay very easy to access by the collector and allows autonomous negotiation between collector and requestor on cooperation, coauthorship in publication or compensation in costs. Thereby, improving availability of large amounts of high quality samples of a highly specified or rare tumor types and contact opportunities for cooperation with other institutes.

Ovarian tissue banking for cancer patients. To do or not to do?

A large proportion of childhood and young cancer patients will lose their fertility after aggressive cancer therapy because of the gonadotoxicities of chemotherapy and radiotherapy. One of the strategies to preserve fertility for those facing premature ovarian failure is ovarian tissue banking. We are seeing a growing enthusiasm about this emerging technology. At the same time, scepticism is prevalent, as the efficacy of ovarian tissue banking for fertility restoration in humans has not yet been proved. However, there is ample evidence of its efficacy in animal studies. Ovarian tissue banking requires further investigations and should be considered experimental in humans at present.
