Abstract

In this study, we investigated the temporal post-mortem limits, within which there will be guarantees of obtaining living cells from several tissues of sheep and cattle and the effect of vitrification on the ability of cells from tissue stored at different times. Muscle tissue and auricular cartilage were stored at 4°C for 5, 48, 72, 96 and 216 h post-mortem (hpm). Tissue samples were sorted into two groups: one group was in vitro cultured immediately after storage and the other was vitrified after storage and then in vitro cultured. In cattle and sheep, no differences in subconfluence rates were observed between the two experimental groups. At the same time, no significant differences were observed in the number of days required in culture to reach confluence between non-vitrified and vitrified groups when tissues were stored at 4°C for different times. In sheep, while the population doubling times (PDT) were similar in cartilage cells from vitrified and non-vitrified tissues and stored at 4°C for 5 and 216 hpm, PDT of muscle cells were longer in 216 hpm stored groups than in 5 hpm stored groups. In bovine, although the PDT of muscle cells were similar for 5 and 216 hpm and both vitrified and non-vitrified tissues and the PDT were longer in cartilage cells from vitrified than from non-vitrified tissues. In conclusion, although storage times and vitrification have different effects on tissues from cattle and sheep, this study showed that living cells could be obtained from all groups. Therefore, cartilage and muscle tissues can be stored at 4°C for 216 hpm and used for cyrobanking.
