Abstract

Background

Although skin vitrification is a tool used to create biobanks for wildlife, its appropriate use can vary in a species-specific manner. Since there are no studies on the conservation of lesser grison skin.

Objective

We proposed to assess two vitrification techniques on the in vitro dynamics of cells recovered from cryopreserved skin.

Methods

Skin (9.0 mm³) was cryopreserved using solid-surface vitrification [SSV group] and direct vitrification in cryovials [DVC group]. Non-cryopreserved skin fragments were used as a control (control group). All fragments were assessed for morphology, viability, degree of apoptosis, population doubling time (PDT), metabolism, reactive oxygen species (ROS) levels, and mitochondrial potential (ΔΨm).

Results

No differences were observed between the groups regarding morphology and metabolism. However, only the cells from the DVC group exhibited viability and PDT rates similar to the control group (p < 0.05). Both vitrification techniques, DVC and SSV, resulted in significant changes in apoptosis, ROS levels, and ΔΨm compared to the control group (p < 0.05).

Conclusion

Although both vitrification techniques promote the recovery of lesser grison somatic cells, DVC maintained a more significant number of cell quality parameters than SSV. These results are the first steps toward forming biobanks of genetic resources in this species.

期刊介绍： Gene Reports publishes papers that focus on the regulation, expression, function and evolution of genes in all biological contexts, including all prokaryotic and eukaryotic organisms, as well as viruses. Gene Reports strives to be a very diverse journal and topics in all fields will be considered for publication. Although not limited to the following, some general topics include: DNA Organization, Replication & Evolution -Focus on genomic DNA (chromosomal organization, comparative genomics, DNA replication, DNA repair, mobile DNA, mitochondrial DNA, chloroplast DNA). Expression & Function - Focus on functional RNAs (microRNAs, tRNAs, rRNAs, mRNA splicing, alternative polyadenylation) Regulation - Focus on processes that mediate gene-read out (epigenetics, chromatin, histone code, transcription, translation, protein degradation). Cell Signaling - Focus on mechanisms that control information flow into the nucleus to control gene expression (kinase and phosphatase pathways controlled by extra-cellular ligands, Wnt, Notch, TGFbeta/BMPs, FGFs, IGFs etc.) Profiling of gene expression and genetic variation - Focus on high throughput approaches (e.g., DeepSeq, ChIP-Seq, Affymetrix microarrays, proteomics) that define gene regulatory circuitry, molecular pathways and protein/protein networks. Genetics - Focus on development in model organisms (e.g., mouse, frog, fruit fly, worm), human genetic variation, population genetics, as well as agricultural and veterinary genetics. Molecular Pathology & Regenerative Medicine - Focus on the deregulation of molecular processes in human diseases and mechanisms supporting regeneration of tissues through pluripotent or multipotent stem cells.
