Hypothermic storage of equine isolated hepatocytes.

The research article focuses on determining the best technique for the cold storage of horse liver cells, or equine hepatocytes. The study concludes that University of Wisconsin Solution (UW) preserves these cells effectively at 4 degrees Celsius for at least 24 hours.

Research Aim and Methodology

The principal objective of this research paper was to identify the ideal methods for the hypothermic – or cold – storage of equine isolated hepatocytes, a type of horse liver cell. The cell’s viability post-storage would be determined by specific factors such as the kind of storage medium used, cell density in the storage suspension, and the duration of preservation.

Findings and Evaluations

• The study noted that hepatocytes stored at 4 degrees Celsius in Hanks’ Balanced Salt Solution (HBSS) and Williams’ Medium E (WE) for 24 hours had very low viability. The cells displayed numerous cell membrane blebs, a bubble-like anomaly that reveals cell damage, a low attachment rate, and reduced MTT rates. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) reduction rate is commonly used to evaluate cell metabolic activity, and a decrease indicates lowered cellular health and functionality.
• In contrast, hepatocytes stored in University of Wisconsin Solution (UW) for 24 hours at a density of 12.5 x 10(6) cells/ml were found to maintain high viability of over 70%, typical and intact morphology, high cell attachment rates, and strong MTT reduction. These findings highlight UW as an effective preservation solution for equine isolated hepatocytes.

Conclusion

Through this study, the researchers demonstrate that University of Wisconsin Solution (UW) is an effective solution for the storage of equine isolated hepatocytes. It allows for hepatocytes obtained from slaughterhouse organs to be stored at a temperature of 4 degrees Celsius at a density of 12.5 x 10(6) cells/ml for at least 24 hours without significant deterioration in their functionality or structural integrity.
