Preserving genetic material in cryogenic conditions presents a viable alternative for the protection of species' gene variability. However, there is an enormous need to establish and test cryopreservation protocols that are suitable for each diverse cell type to guarantee technical success in the long run. Considering this, fibroblasts from jaguar (Panthera onca), oncilla (Leopardus tigrinus), and pampas cat (Leopardus colocolo) were subjected to cell characterization and then cryopreservation in different cryoprotectant solutions (2.5%, 10% dimethyl sulfoxide [DMSO] or CryoSOfree?). Further testing was conducted to determine each solution's performance in preserving cell viability. In culture, a growth curve to assess cellular growth potential showed that exponential proliferation lasts for about the first 50 hours of in vitro culturing, declining in pace afterward. L. colocolo and L. tigrinus presented no difference in cell viability while using 2.5% DMSO protocols. P. onca cells did not present difference on viability for both concentrations of DMSO. Protocols using CryoSOfree resulted in a decreased viability of P. onca fibroblasts. Morphological differences between fibroblasts among the species were noted under bright field microscopy and scanning electron microscopy. L. colocolo and P. onca cells are fusiform, and L. tigrinus are spherical. All cells presented cytoplasmic projections. Transmission electron microscopy revealed vacuoles and secretion granules, indicating intense cell activity after thawing. Differences found in the efficiency of cryopreservation protocols according to the type of cryoprotectant indicate that species react differently to freezing and thawing processes. This research evaluates key aspects of in vitro protocols for cryopreservation of wild animals, which need to be optimized to guarantee successful cell culturing. More suitable protocols lead to increased efficiency in establishing fibroblast cryobanks and also facilitating the use of wild cats' cells in cloning techniques, contributing directly to preserving wild fauna.
