#1
William E Grizzle, Katherine C Sexton
Many classic biobanks collect more human tissues than they distribute, leading to increased inventories, unnecessary storage, increased expenses, and reduced chargeback income. This situation is a result of biobanks operating without well-defined goals, having incorrect views of the potential number of investigators who will utilize specimens, and collection of biospecimens without adequately considering the need for specific tissues by investigators. These deficiencies frequently lead to unrealistic plans for biospecimen utilization and biobanks that are larger than necessary...

The cryotolerance of farm animal spermatozoa varies according to their specific features, such as size, shape, and lipid composition. Thus, it is impossible to develop a standardized freezing procedure for different kinds of livestock species. The establishment of an efficient semen cryopreservation procedure will facilitate long-term conservation of small ruminant genetic resources and extension of artificial insemination in daily production. Different from sheep, goat seminal plasma contains a phospholipase, which can affect spermatozoa viability through interaction with milk or egg yolk...

One of the main problems in the cryopreservation of biological samples is the formation of ice and the consequent mechanical damage to cells and tissues, due to the crystalline structure of ice and its associated mechanical damage. It is necessary to detect this deleterious formation of ice, especially in tissues and organs, because of their large volume and the complexity of their vascular system in the case of bulky organs. In this work, we propose the use of X-ray Computed Tomography (CT) to detect this ice formation inside tissues and organs...

A major concern in biomedical research is the quality of biological samples. RNAlater is a stabilizer, which was originally developed for RNA preservation in fresh tissues and is important for collection and transportation. However, this reagent lacks a comprehensive and systematic evaluation of its preservative effect on different mammalian tissues under consistent experimental conditions. In this study, we collected liver, kidney, testis, brain, and colon tissues from mice and divided the samples into the following respective groups: fresh, RNAlater preserved, and liquid nitrogen snap frozen...

BACKGROUND: Molecular research is increasingly dependent on high-quality biobanked biospecimens. Preanalytical variables in tissue processing and preservation may influence the RNA quality and research results. Hence, the effect of long-term storage and clinicopathological parameters on RNA quality needs to be elucidated. METHODS: Ninety gastric cancer tissue samples were collected and fresh-frozen in a -80°C freezer for 12 years (2006-2017). The histology was assessed and RNA integrity number (RIN) was detected by an Agilent 2100 Bioanalyzer...

Prospective collection is a model through which biospecimens are provided for research. Using this model, biospecimens are collected based on real-time requests from the research community instead of being collected based on the prediction of future requests. We describe the lessons learned by two bioresources that have operated successfully using a prospective model for over three decades. Our goal is to improve other bioresources by increasing utilization of biospecimens that honor consented donors who provide biospecimens to the research community; this provides strong evidence of stewardship of the public trust...

Short-term storage of ovaries during their transport from the collection sites to the specialized laboratories allows the recovery of thousands of oocytes from females of high genetic value, endangered species, and companion or transgenic animals, which sometimes die unexpectedly in the field, or are ovariectomized for medical reasons. Therefore, several studies have been performed to find ideal protocols to preserve oocyte viability during ovarian tissue transport, thus ensuring the success of techniques that are performed after the storage, such as cryopreservation and/or in vitro follicle culture...

Quality specimens from biobanks are key resources to support reproducible research. Sustaining biobanks requires robust management. We recently published a pilot survey that indicated that over half the participating biobanks had business plans in place and another third were working on business planning. While the results provided a clue to the status of business planning in biobanking, it was concluded that a longer and more in-depth survey and analysis were required. In April 2017, an extended survey was distributed worldwide in English, French, Chinese, German, and Spanish, through multiple channels...

Biobanking is increasingly important in studying complex heterogeneous diseases. Therefore, it is essential to ensure the sample quality after long-term storage for reliable downstream analyses. The Clinical Biobank of the Jessa Hospital and the University Biobank Limburg (UBiLim) hold a continuously growing collection of hematological samples, including May-Grünwald-Giemsa (MGG)- and Perls' Prussian Blue (PPB)-stained bone marrow (BM) smears, stored at room temperature (RT) for up to 20 years. In this study, we investigated the effect of short- and long-term storage on the quality of DNA and RNA extracted from these BM smears to assess their fitness-for-purpose in downstream molecular applications, including agarose gel electrophoresis, bio-analyzer analysis, quantitative polymerase chain reaction (qPCR), and targeted next-generation sequencing (NGS)...

Blood is a biological fluid that contains multiple blood fraction and cellular components. High-quality blood specimens are essential prerequisites for various downstream applications such as molecular epidemiology studies, genomics, and proteomics studies. Currently, protocols and research publications concerning the collection, handling, preservation, and stability of blood or blood fractions are constantly emerging. Moreover, standardized guidelines are a requirement for biorepositories to tightly control preanalytical variables originating from these procedures and obtain high-quality blood specimen for downstream analyses...

Leukocytes function as central effectors in innate immunity (such as phagocytosis) as well as adaptive immunity (e.g., antigen-dependent T cell activation), and serve as an important resource in the fields of translational medicine, precision medicine, and cell therapy. Isolation of leukocytes from whole blood is necessary for high-quality RNA and downstream research. This process is susceptible to the variability of many factors, such as blood collection, isolation reagents, and extraction methods. In this study, three methods were applied for leukocytes separation, followed by RNA extraction and quality testing to evaluate the methods...

BACKGROUND AND AIM: It is increasingly recognized that biomedical research has serious reproducibility issues, which could be overcome at least in part by standardized processing of biomaterials. Therefore, professional biobanks have emerged, positively influencing sample and data quality. However, quantitative data about a biobank's contribution to published results are still hard to find, although they could serve as valuable benchmark figures for the community. We therefore aimed to report usage data from the MedUni Wien Biobank facility regarding its prospective fluid cohorts...

Animal-derived products are widely used in sperm cryopreservation for their cryoprotective properties. These components, however, tend to be replaced because of sanitary risks. STEMALPHA.CRYO3 (Ref. 5617; Stem Alpha, Saint-Genis-l'Argentière, France), called "CRYO3," is a chemically defined preservation medium currently used for freezing human tissue and adult stem cells. The aim of this study was to evaluate the effect of a CRYO3-based medium on ram sperm freezing regarding in vitro parameters and in vivo fertility...

The ability of various pectin polysaccharides to modify the morphological structure of ice during the phase transitions from water to ice was studied. Pectins were isolated from Sosnowsky's hogweed Heracleum sosnowskyi Manden (heracleuman-N6HS), tansy Tanacetum vulgare L. (tanacetan-N7TVF), and Rauwolfia serpentina Benth callus (rauwolfian-N8RS). Pectins were isolated by multistep extraction. The effect of pectins was assessed using osmometry, thermographic analysis, and cryomicroscopy. A concentrate of leukocytes was used as the sample for the subsequent freezing step...

AIM: To ensure that sample quality meets the requirements of experimental research, the gynecology and obstetrics biobank of the Nanjing Drum Tower hospital designed different quality control methods for relevant types of samples. A range of quality control procedures has been formulated. METHODS: The sample types were frozen tissue, paraffin-embedded tissue, optimal cutting temperature (OCT)-embedded tissue, plasma, buffy coat, serum, blood clots, and urine. Different categories of samples from a random selection of 1% of cases were analyzed for quality control experiments: (i) frozen tissue, buffy coat, and blood clots: RNA and DNA were extracted and the concentration, purity, and integrity were determined; (ii) paraffin-embedded tissue: morphological observations were made after hematoxylin-eosin staining and immunohistochemical detection of β-actin or CD10; (iii) OCT-embedded tissue: hematoxylin-eosin staining and immunofluorescence detection of β-actin; and (iv) frozen tissue samples derived from different organs of 18 fetal autopsy specimens with different cold ischemia times (CITs), 0-12 hours, 12-18 hours, 18-24 hours, and 24-48 hours, were chosen to study RNA quality...
