Multiple types of organizations have developed to supply human tissues to support biomedical research. These organizations follow different models including the specific models of 1) prospective collection, 2) tissue banking, and 3) tissue collection associated with clinical trials as well as the model of 4) a tissue resource that incorporates features of the other models. These types of organizations devoted to supplying tissues for research have chosen different goals to meet the different tissue and informational needs of the investigators to whom they supply tissue. In order to provide high quality tissues to support research, all models should rely on a strong quality assurance program with extensive quality control of the tissues being provided to support research. In addition to facilities which collect, process, store and provide tissues, the need for a rigorous QA program applies to all resources and infrastructures used to support biomedical research. The UAB Tissue Collection and Banking Facility which provides human tissue to support biomedical research has been functioning and developing since 1979. To our knowledge, similar programs in providing tissues from animals are less developed, but could easily follow the models which UAB and other institutions providing human tissues have established, including the approaches of UAB and others to QA and QC. This manuscript reviews the current concepts of QA and QC in use in organizations supplying tissue to support biomedical research as well as new approaches in QA and QC that have been proposed.","PeriodicalId":51233,"journal":{"name":"Cell Preservation Technology","volume":"6 2 1","pages":"113-118"},"PeriodicalIF":0.0,"publicationDate":"2008-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1089/CPT.2008.9993","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60916146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A stream imaging system composed of a microfluidic device, a charge-coupled device camera, and a microscope has been developed to study the osmotic behavior of multiple cells in response toward their extracellular environment. Cells of interest were first mixed with the desired extracellular medium and streamed into a microchannel. The microchannel confines the movement of the cells in a monolayer and allows cells to move along the flow direction only. The cells then pass through a sensing zone where the images of cells were capable of being captured under a microscope. Using mouse dendritic cells (mDCs) as a model system, the membrane transport properties were investigated. The kinetics volume changes of mDCs under various extracellular conditions at room temperature (22°C) were analyzed using a biophysical model to determine water and cryoprotectant transport properties of the cell membrane. This prototype system directly allows us to observe, trace, capture, and store the sample information in terms of number, concentration, dynamic size, or shape for further analyses and documentations. We believe that the system has the potential of being used as a stand-alone equipment, or integrated into a lab-on-a-chip system, or embedded into commercialized instruments.</p>","PeriodicalId":51233,"journal":{"name":"Cell Preservation Technology","volume":"6 2","pages":"125-132"},"PeriodicalIF":0.0,"publicationDate":"2008-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1089/cpt.2008.0002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29032318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study we assessed two procedures to cryopreserve skin biopsies from live brown bears. Skin biopsies were taken from six live, anesthetized brown bears. Single biopsies (n = 3) of each animal were cut into small pieces and assigned to one of the three experimental groups: freezing, vitrification, or untreated fresh. There were no differences on cell attachment. However, both freezing and fresh culture allowed for higher cell proliferation (p < 0.05) and less days to reach 70% to 80% confluence (p < 0.03) than vitrification. Skin biopsies from brown bears can be preserved long term, allowing fibroblasts to proliferate in culture. Slow freezing was effective to cryopreserve skin biopsies from brown bears.","PeriodicalId":51233,"journal":{"name":"Cell Preservation Technology","volume":"6 1","pages":"83-86"},"PeriodicalIF":0.0,"publicationDate":"2008-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1089/CPT.2007.0518","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60915137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimal and efficient transformation requires an accurate assessment of the titer of the virus in each virus preparation. However, current methods to determine EBV titer assess transformation efficiency using large-scale biological assays ending in the establishment of lymphoblastoid cell lines (LCLs). This method determines the virus dilution capable of producing LCL outgrowth but does not determine virion number and optimal dilution will vary with the preparation. Therefore, we developed a real-time PCR method to detect and quantify EBV DNA. In addition to quantifying the titer of the viral supernatants, we evaluated both the biological activity of the viral dilutions as measured by LCL outgrowth and the use of diluted EBV viral stocks to transform previously fr...","PeriodicalId":51233,"journal":{"name":"Cell Preservation Technology","volume":"6 1","pages":"73-81"},"PeriodicalIF":0.0,"publicationDate":"2008-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1089/CPT.2007.0515","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60914910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Critical to the success of biorepository operations is the safe, secure, viable storage of the specimens entrusted to its care. The primary means by which this is accomplished is to ensure proper function of ultralow freezers. For a large biorepository this involves the tracking and monitoring of hundreds of freezers. Biorepository procedures typically require recording of the temperature of each freezer on a daily basis. At the Central Repository of the National Cancer Institute in Frederick, Maryland, temperature monitoring has been taken one step further. New procedures utilize the in-house 24-h temperature monitoring system to produce daily printouts of the fluctuation of temperature with time. These graphs are reviewed, and based upon an understanding of freezer compressor cycles are used to identify potential problems with freezer function.
