This suggests the need for better planning by these biobanks around what new biospecimens to collect and store and more deliberate approaches to determine the value of existing biospecimen collections to make operational decisions. Existing biospecimen collections may comprise part of the biobank inventory (where decisions are needed around availability or continued storage) or external collections (where decisions are needed to consider their addition to the inventory). However, there has been limited discussion about how to value these collections. This paper proposes a guideline for the valuation of existing collections based on a two-stage process that involves consideration of features under two broad categories: \"ELSI\" factors and \"Biospecimen and Data\" factors. The first \"initial-valuation\" stage is based on the consideration of five key questions related to each of the main factors and will, in many instances, suffice. This approach can identify salient features of a collection that may have a dominant impact on the value. However, in other instances, a second \"extended-valuation\" stage may be needed to make a more in-depth assessment of the features of a collection. The overall value can then be summarized and/or assigned a score and compared with valuations of comparable collections. The latter might include another collection occupying a similar storage volume within the biobank, a collection from a similar group of donors, or a similar collection stored by another affiliated biobank. In summary, we hope that these guidelines and discussion serve to highlight key factors and an approach to valuing existing collections to improve biobanking efficiency and sustainability.</p>","PeriodicalId":55358,"journal":{"name":"Biopreservation and Biobanking","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143804801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From the moment of collection in the field, transport media must ensure tissue viability by providing the necessary nutrients until laboratory processing for culture or cryopreservation. This study aimed to evaluate the effects of temperature and storage duration on tissue viability and cell growth using two types of skin transport media: Dulbecco's modified Eagle medium (DMEM) supplemented with 15% fetal bovine serum and 0.9% physiological saline solution. Skin fragments were collected from the inguinal region of five captive gray-brocket deer (<i>Subulo gouazoubira</i>) and divided into small samples, which were randomly assigned to each transport medium. The samples were stored at 5°C and 24°C for 24 and 72 hours, followed by cryopreservation and thawing to assess histomorphology, apoptosis (TUNEL test), cell growth, viability (Trypan blue and MTT assay), and mitotic index. The results showed that physiological saline solution is as efficient as DMEM in maintaining tissue viability, with 80% of viable cells observed and no significant difference after storing in different skin transport media (<i>p</i> > 0.05). Cell morphology and apoptosis did not change in response to media, temperature, or storage duration. We recovered metaphases from all skin tissue storing conditions, with a similar mitotic index to those presented in other cell culture studies from deer biopsies. These results showed the feasibility of storing skin tissue samples during 24 and 72 hours at 5°C and 24°C in different transport media guaranteeing the cell growth and viability for genetic studies and reproductive biotechnologies. The study may contribute to sampling collection in places where displacement with large equipment is limited, allowing the establishment of simplified skin transport protocols as an important step to accessing genetic material from individuals inhabiting isolated localities.</p>","PeriodicalId":55358,"journal":{"name":"Biopreservation and Biobanking","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143733379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
