The primary results showed : using m199 as diluents containing 20 % bovine serum, it is better to freeze the cells slowly freezing at fist then increase freezing speed ( for example, from 0 to - 6 freezing speed is about - 0. 05 a minute, from - 6 to - 40, freezing speed is about - 0. 5 a minute ), studies on effect of various concentration of dmso demonstrate that about 12. 5 % dmso gave the highest post - thaw percentage of viable cells. the concentration of bovine serum had no different effect on the percentage of the viable embryo cells of misgurnus auguillicaudatus. the embryo cells derived 6 from the later stage of blastula offish is more resistant to the cryogen than the cells of early stage of blastula. the cells preserved in liquid nitrogen at - 196 were thawed and cultivated, a few cells were found adhere to the surface of culture vessel when the percentage of viable cell was more than 30 %. the cells in only two culture vessels were found to proliferated and gave rise to many small morphologically undifferentiated cells
研究初步表明:以細胞培養液m199 （含2既的小牛血清，常規量雙抗）為凍存稀釋液對泥鰍胚胎細胞冷凍保存宜採取先慢后快的方式（例如，從0一一6 ，凍存速度為一0 . 05 / min ，再以一0 . 5 / min的速度從一6一一40 ） ; dmso的保護效應濃度為12 . 506左右;小牛血清的濃度對泥鰍胚胎細胞的成活率影響不明顯;囊胚晚期細胞抗凍性比中早期強;通過對不同批次的凍存細胞解凍培養，解凍后成活率為30 %以上細胞培養
