cell breeding meaning in Chinese

细胞育种

Different from mammals , the early embryos of fish can not be preserved for the long period at the very low temperature ( - 196 ) . therefore , three methods were usually applied to cryogenic preservation of the fine and rare species of fish : 1 ) perserving fish spermatozoon in cryogenic condition . researchers have had systematically studied on this technique for many years , and this technique has been utilized in application and made a lot of effects ; 2 ) combining with the techniques of cell engineering ( nuclear transplantation and electric fusion etc . ) , and through the process of culturing histiocyte of fish , cryopreservation and re - culture after thawing , carrying out somatic cell breeding of fish . the past studies showed that the nucleolus of somatic cells of fish have totipotency
多年来，国内外学者对各种鱼类精液的冷冻保存进行了大量的系统研究，目前这项技术已达到实用水平，并日益发挥作用；二是对鱼类培养的组织细胞冷冻保存，通过鱼类细胞的培养、超低温冻存、解冻后再培养过程，结合细胞工程技术(如核移植、电融合等)进行体细胞育种；大量的研究结果表明鱼类体细胞核具有发育的全能性，随着细胞培养技术、细胞工程技术日益发展成熟，完全具备实现鱼类物种种质长期保存的理论基础和技术条件。
