摘　　要：应用组织块培养法从胎牛耳部分离培养了胎牛成纤维细胞。应用PCR方法鉴别了细胞的性别。选择雌性成纤维细胞,进行了形态观察、生长曲线测定、染色体分析。结果表明,分离培养的细胞具有正常的大小、形态、分裂增殖特性和染色体数目。胎牛成纤维细胞的培养方法的建立以及其相关的生物学特性的分析,有利于给同种和异种体细胞克隆牛研究提供形态良好、染色体数目正常的供体细胞,同时也为体细胞转基因等其他领域的研究提供了基础条件。The bovine fetal otic fibroblast cells were isolated using tissue bulk attachment. The gender of fetus was identified using PCR. The fibroblast cells from female fetus were chosen for further morphologic observation,growth curve and chromosome analyzing. The results indicated that the cells had normal morphology,multiplication characteristics and chromosome number. The establishment of culture method and related biological characterization analysis of bovine fetal fibroblast provided not only a ready supply of somatic cells for the intraspecies and interspecies cloning of macaque but also fundamental conditions for somatic transgene and other related fields.
