Simplified cryopreservation media preserve deer skin cells for wildlife biobanking
Published in Biology, Journals, Vitrification.
Published October 11, 2026. A study published in Biopreservation and Biobanking on October 9 examined simpler media for preserving deer skin tissue, with potential applications in wildlife genetic-resource banks.
UNESP researchers compared conventional laboratory media with saline-based formulations containing table sugar and dimethyl sulfoxide. They tested slow freezing and needle-immersed vitrification in red brocket deer (Mazama rufa) and marsh deer (Blastocerus dichotomus).
Fibroblast cultures could be established after thawing, and the simplified media performed comparably to conventional formulations in the reported tests. Results depended on both species and method: in red brocket deer, slow freezing preserved more viable cells, while vitrification produced higher mitochondrial-activity measurements.
Scope: The findings concern sampled skin tissue and subsequent cell culture. They do not demonstrate preservation of a whole animal or establish a human cryonics protocol. The study suggests a route toward more accessible somatic-cell biobanking, with species-specific validation still necessary.
