However, the use of fresh samples is limited to the use at field conditions because the analysis is performed under laboratory conditions. Thus, this study aimed to develop a simpler procedure for storing dry semen at 28 °C to reduce cold storage costs. For this, semen samples were evaluated according to established quality semen parameters, a protocol for dry, and 3 sterilization treatments of dry semen were applied to the store. The integrity of the DNA was evaluated every two months, using fresh semen, dry semen (untreated), and particles 3C to compare the peaks by flow cytometry. The results indicated that all samples evaluated before and after drying showed no significant difference in the DNA content. UV-treated semen showed a 1C peak in the histogram up to 180 days of storage and a non-significant difference (<em>P &gt; 0.05</em>) from fresh control in the number of DNA particles up to 120 days and untreated only showed a 1C peak up to 120 days. The developed method may become an interesting procedure to serve as a reference peak for practical flow cytometric analysis, not only in the field of fish biology but also in biomedical and agricultural sciences. Furthermore, dried semen can become a tool for the preservation of genetic material and is a promising low-cost storage technique for biobanking.</p></div>","PeriodicalId":10897,"journal":{"name":"Cryobiology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140650603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One promising approach is stem cell therapy, particularly multipotent mesenchymal/stromal stem cells (MSCs). These cells have shown significant efficacy in addressing various diseases in livestock that exhibit resistance to conventional therapies. Adipose tissue-derived MSCs (ADSCs) have garnered attention due to their accessibility and robust expansion potential. The current study comprehensively characterises buffalo ADSCs (bADSCs), confirming their identity as MSCs capable of differentiating into diverse cell lineages—the identified characteristics position bADSCs as promising candidates for applications in regenerative medicine, applicable in veterinary contexts. Notably, the study established that a cryoprotective solution comprising 10 % dimethyl sulfoxide and 90 % fetal bovine serum is optimal for preserving bADSCs. This cryoprotective solution maintains vital parameters, including viability, apoptosis, senescence, cell adherence, adherent cell viability, metabolic and clonogenic efficiency, and the activity of reactive oxygen species and trilineage differentiation potential following thawing. These findings lay the foundation for developing a cryo-banking system for bADSCs. Subsequent research efforts are focused on exploring the therapeutic potential of bADSCs in specific disease models and clinical settings. The outcomes of such investigations may pave the way for innovative and effective treatments, further enhancing our understanding of the regenerative capabilities of bADSCs.</p></div>","PeriodicalId":10897,"journal":{"name":"Cryobiology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140641113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Faster cooling and warming rates enable lower concentrations and perfusion times, reducing toxicity. Since warming rates necessary to avoid ice formation during recovery from vitrification are typically faster than cooling rates necessary for vitrification, warming speed is a major determining factor for successful vitrification. Dielectric warming uses an oscillating electric field to directly heat water and cryoprotectant molecules inside organs to achieve warming that's faster and more uniform than can be achieved by heat conduction from the organ surface. This work studied 27 MHz dielectric warming of rabbit kidneys perfused with M22 vitrification solution. The 27 MHz frequency was chosen because its long wavelength and penetration depth are suitable for human organs, because it had an anticipated favorable temperature of maximum dielectric absorption in M22, and because it's an allocated frequency for industrial and amateur use with inexpensive amplifiers available. Previously vitrified kidneys were warmed from −100 °C by placement in a 27 MHz electric field formed between parallel capacitor plates in a resonant circuit. Power was varied during warming to maintain constant electric field amplitude between the plates. Maximum power absorption occurred near −70 °C, with a peak warming rate near 150 °C/min in 50 mL total volume with approximately 500 W power. After some optimization, it was possible to warm ∼13 g vitrified kidneys with unprecedentedly little injury from medullary ice formation and a favorable serum creatinine trend after transplant. Distinct behaviors of power absorption and system tuning observed as a function of temperature during warming are promising for non-invasive thermometry and future automated control of the warming process at even faster rates with user-defined temperature dependence.</p></div>","PeriodicalId":10897,"journal":{"name":"Cryobiology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0011224024000488/pdfft?md5=aeaf52e3b1acbf7ebd38948c73ede8f5&pid=1-s2.0-S0011224024000488-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140618730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
