摘要: 本研究利用组织块贴壁培养法对鲁西黄牛、蒙古马、北京鸭和狼山鸡等4个品种体外培养细胞的生长、分化规律进行了研究。通过绘制其生长曲线和在激光共聚焦显微镜下拍摄细胞生长过程,初步分析成纤维细胞的生长、分化规律。试验结果表明,4个品种的细胞生长曲线均呈明显的“S”形,家畜和家禽的细胞潜伏期和停滞期的长短以及细胞群体倍增时间均有明显差异,蒙古马和狼山鸡体外培养细胞的单个细胞分裂期也有显著差异,蒙古马为97 min,而狼山鸡为85 min。本试验构建的4个品种成纤维细胞系不仅使畜禽遗传资源在细胞水平永久保存下来,而且为分子生物学研究提供宝贵材料。

Abstract: In order to study on the growth and differentiation rule of cells cultured in vitro of Luxi cattle,Mongolia horse,Peking duck and Langshan chicken,the vitro four cell lines were established successfully in this study with tissure attachment culture method. Analysis on the growth and differentiation rule of fibroblast cell through rendering the growth curve and photographing the cells growth process by Confocal Laser Scanning Microscopy. The experimental results indicate that: the four cell growth curves are all showed significantly sshape, the length of retention period and incubation period are obviously different between livestock and poultry cells , and the doubling time for livestock and poultry cells are also, in addition, the single cell division period of Mongolia horse and Langshan chicken cells cultured in vitro are obviously different too, the former is 97 min and the latter is 85 min.

Key words: livestock and poultry; fibroblast cell; growth rule; growth curve; division period
