鱼类培养细胞核发育潜能的研究

STUDIES ON THE DEVELOPMENTAL POTENTIALITY OF CULTURED CELL NUCLEI OF FISH

  • 摘要: 本文用细胞核连续移植方法,从鲫鱼囊胚细胞的继代培养细胞,获得一尾存活达三年之久的移核鱼,但性腺未分化,不育。并从性成熟的鲫鱼短期培养肾细胞,获得一尾完成发育的性成熟的成鱼。实验结果提示鱼类囊胚细胞的继代培养细胞核和已分化的成鱼体细胞核仍具发育的全能性,为用细胞核移植方法进行鱼类体细胞育种的可能性提供了依据。

     

    Abstract: By means of the serial nuclear transplantation technique, the authors obtained an nuclear transplant fish from subcultured cell originated from the blastula cells of the crucian carp (Carassius auratus L.). This nuclear transplant fish survived for three years, but its sexual glands were undifferentiated. The authors have also abtained an sexually mature adult fish from short-term cultured kidney cell nucleus of an adult crucian carp.Results of the experiment implied that the subcultured cell nuclei of fish blastula cells and the specialized somatic cell nuclei of adult fish still retained their developmental totipotency, and thus, it indicated that there is a possibility of fish somatic cell breeding through the use of the nuclear transplantation.
