摘　　要：本研究旨在建立一种简单易行、获取细胞纯度高的绒山羊附睾上皮细胞体外培养体系。10~12月龄绒山羊附睾头部分别采用酶消化法和改良组织块消化法进行原代培养,利用免疫细胞化学染色法和免疫荧光化学法对细胞进行鉴定,同时利用流式细胞仪和CCK法分别检测细胞纯度和增殖情况,在电镜下观察细胞超微结构。结果表明,两种培养方法所获的细胞均呈岛屿状克隆生长和较好的增殖能力,具有活跃的分泌和代谢功能;上皮细胞特异性的角蛋白18和附睾特异性的谷胱甘肽过氧化物酶5(GPx5)的表达以及流式细胞仪结果显示,两种方法所获细胞均为纯度较高的附睾上皮细胞,但改良组织块消化法获得原代细胞需要的时间长,酶消化法获得原代细胞时间短,获得的细胞量大。本研究结果为进一步研究绒山羊附睾上皮功能提供了良好的基础。The aim of this study was to establish a simple and feasible in vitro culture system for high purity epididymal epithelial cells from cashmere goat.The primary cells were obtained from epididymal caput of 10-12 months cashmere goat using enzymatic dispersion and improved tissuepiece digestion method.The cells were identified by immunocytochemistry and immunofluorescence methods.Cell purity and proliferation were also investigated respectively by flow cytometry and CCK method.Ultrastructures of epididymal epithelial cells were observed under transmission electron microscope.The results showed that the cells obtained by both methods were in islandlike clonal growth and good proliferation ability,and possessed active secretory and metabolic function.The expression of epithelial special cytokeratin 18 and epididymal special glutathione peroxidase 5（GPX5）and the result of flow cytometry showed that both methods could obtain high purity epididymal epithelial cells.The primary cells obtained by improved tissue-piece digestion method took a long culture time,compared to that the primary cells obtained by enzymatic dispersion method which took a short culture time with more cells.These results provided a good foundation for further study on the function of epididymal epithelial cells of cashmere goat.
