摘要: 为了研究藏獒体细胞生物学特性和保存藏獒遗传资源,采用组织块法建立了2株藏獒成纤维细胞系,对体外培养的细胞形态、增殖能力和部分生物学特性进行了分析。结果表明,体外培养的藏獒细胞呈现典型的成纤维细胞形态,生长良好,增殖能力强,测定的细胞群体倍增时间为46.1 h;经免疫荧光染色,细胞表达波形蛋白;F5代细胞正常二倍体核型率为91.4%,藏獒核型2n=78,X染色体为亚中着丝粒染色体,Y染色体为端着丝粒染色体。本研究所建立的藏獒体细胞系为开展藏獒体细胞核移植研究提供了材料。

Abstract: In order to study biological characteristics of Tibetan Mastiff somatic cells and preserve genetic resource, two fibroblast cell strains from Tibetan Mastiff were established by tissue culture. In vitro culture cell morphology, hyperplasia ability and some biological characteristics were researched. Tibetan Mastiff cells in vitro culture appeared typical morphology of fibroblast cells, grew well and had strong hyperplasia ability. Population doubling time of the cells was 46.1 h. Vimentin expression in the cells was confirmed by immunofluorescence staining. The rate of F5 cells with normal diploidy (2n=78) was 91.4%. Moreover, longer X chromosome belonged to submetacentric chromosome, but Y chromosome did telocentric chromosome. Tibetan Mastiff cell strains eslablished in the study offered the materials for the Tibetan Mastiff somatic cell nuclear transfer research.
