Cell viability after freezing and thawing of five Acipenser baerii gonad-derived cell lines. Cell viability was measured immediately after thawing of frozen cells that were stored for 24 to 27 days in liquid nitrogen. More than 79.6 % post-thaw cell viability was observed in all the cell lines except ABG6 that showed 57.6 % cell viability. Non-frozen cells were used as a control. All data are mean ± SD of three the independent experiments. Different letters indicate significant differences, p < 0.05
