摘要: 旨在改良牛子宫内膜细胞原代培养方法,并鉴定其特征。分别比较了单纯组织块培养法和先组织块培养后再消化纯化的方法对牛子宫内膜细胞进行培养以及纯化。经免疫荧光染色方法对两种方法获得的牛子宫内膜上皮细胞进行角蛋白表达鉴定。研究结果表明:先组织块培养后再消化纯化的方法获得的牛子宫内膜上皮细胞形态良好,纯度较高。因此,组织块培养后再消化纯化得到的牛子宫内膜上皮细胞是一种操作简单、高效的方法,用该方法得到的细胞可以在体外传至4~5 代,此结果为牛繁殖生理及其机制模型的建立奠定基础。

Abstract: The aim of this study was to improve the primary culture method of bovine endometrial cells and to identify their characteristics. Tissue pieces culture method and tissue pieces culture first again after digestion and purification methods were used respectively to isolate and culture bovine endometrial cells. The tissue-specific expression of cytokeratin genes in mammary epithelial cells was identified by immunofluorescent cytochemical staining. The results show that the tissue pieces culture first again after digestion purified method can acquire high percent of live cells and high purity of cells. Therefore, this method is an easy repeatable method for bovine endometrial epithelial cells culture in vitro. The cells obtained by this method can be cultured up to 4-5 passages in vitro, the culture of bovine endometrial cells in vitro establishes a foundation for research of physiological and mechanism of bovine reproduction.
