However, due to overfishing and long-term artificial breeding, the germplasm has degraded in recent years, and the wild germplasm has been listed as critically endangered. It is urgent to protect the germplasm resources of <em>Larimichthys crocea</em>. Cryopreservation may be an alternative way, however, the toxicity of cryoprotectants and the complicated preservation procedure that uses a programmable freezer has greatly increased the difficulty of cryopreservation. Therefore, in this study, we aimed to explore an efficient, convenient, inexpensive and low toxicity method for cryopreservation of mature testes in this species. The cryoprotectants of dimethyl sulfoxide (Me<sub>2</sub>SO), ethylene glycol (EG), propylene glycol (PG) were selected to cryopreserve the mature testes with liquid nitrogen in simple style. Finally, the testes were cut into blocks (1.0 cm<sup>3</sup>) with cryoprotectants of 20 % PG and 15 % Me<sub>2</sub>SO, placed at a position 10 cm above the liquid nitrogen for 10 min, then plunged into liquid nitrogen, resulting in high survival rate of 64.17 % at 3 days post cryopreservation. And the recovery rate of spermatogonia was more than 70 %. Subsequently, the cells viability were further detected by qRT-PCR, <em>in situ</em> hybridization (ISH) and germ cell transplantation. These results suggested that the spermatogonia from cryopreserved testes had high viability, which could migrate and colonized after transplantation. The present study first established cryopreservation protocols of mature testis in <em>Larimichthys crocea</em>, which will serve as a promising tool to protect Sciaenidae and other fish germplasm resources.</div></div>","PeriodicalId":10897,"journal":{"name":"Cryobiology","volume":"120 ","pages":"Article 105293"},"PeriodicalIF":2.1,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144864717","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}

After a recovery period in culture, the cell membranes regained their integrity, despite being temporarily permeable right after rehydration. Additionally, the inclusion of inulin helped to reduce the residual moisture content and increase the stability of the lyophilizates, while also preserving metabolic activities and the ability to differentiate (including IL-1β release after stimulus). Trehalose and inulin work well together as a lyoprotectant, lowering the stress that THP-1 cells experience during the lyophilization process.

The blue mussel (<em>Mytilus galloprovincialis</em>) is an important species for the aquaculture industry and a useful model for studying cryopreservation in marine invertebrates. Declining mussel seed availability over the past decade, combined with the growing demand for year-round hatchery production, has increased interest in developing effective cryopreservation methods for gametes and embryos. However, cryopreservation remains challenging, particularly for marine invertebrate oocytes, as it requires balancing cryoprotectant cytotoxicity with sufficient cell protection during freezing and thawing. Moreover, the molecular, structural, and functional changes associated with oocyte cryopreservation in invertebrates are still poorly understood. This study examines the effects of two commonly used cryoprotectants, dimethyl sulfoxide (DMSO) and ethylene glycol (EG), on <em>M. galloprovincialis</em> oocytes under a monitored slow freezing (MSF) protocol. Using an integrative analytical approach combining proteomics, functional assessments, and structural analyses, we provide a comprehensive understanding of cryoprotectant-induced changes. Our findings reveal that cryoprotectants cause significant proteomic alterations, with DMSO having more pronounced effects. These alterations are associated with increased oxidative stress, an insufficient antioxidant response, and disruptions in meiosis restart mechanisms, ultimately delaying larval development. Cryoprotectant-induced oxidative stress may also weaken the oocyte membrane, leading to rupture during the MSF protocol and subsequent fertilisation failure post-thawing. These results provide evidence that EG is less cytotoxic than DMSO and suggest that supplementing cryoprotectants with antioxidants and membrane stabilizers could enhance success rates in the cryopreservation of oocytes from mussels and other marine invertebrate species.</div></div>","PeriodicalId":10897,"journal":{"name":"Cryobiology","volume":"120 ","pages":"Article 105288"},"PeriodicalIF":2.1,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144766769","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}

These processes face severe challenges due to the formation of ice crystals that can damage cellular structures. Cryoprotectants (CPAs) are vital in reducing this damage by inhibiting ice nucleation and growth. The present study examines the use of various CPAs, focusing on their ability to enhance the survival of <em>Bacillus coagulans</em> and <em>Streptococcus thermophilus</em> during cryo-freezing and lyophilization. Using density functional theory (DFT) calculations, we analyzed interactions between water molecules. We selected CPAs (sucrose, fructosofuranose, glucose, fructose, and glycerol) to predict their effectiveness in forming protective hydrate shells around bacterial cells. Our results indicate that sucrose, which has a low Gibbs free energy of solvation at low temperatures, provides the most effective cryoprotection. Experimental validation showed that a 12 % sucrose solution improves bacterial survival after lyophilization. We also investigated the effect of different freezing protocols on bacterial survival. Initial freezing at −18 °C and subsequent storage at −80 °C were the optimal methods, maximizing cell survival. The findings contribute to a deeper understanding of cryopreservation and lyophilization processes, with potential applications in biotechnology and biomedical fields.</div></div>","PeriodicalId":10897,"journal":{"name":"Cryobiology","volume":"120 ","pages":"Article 105282"},"PeriodicalIF":2.3,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144569739","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}
