摘要: 通过体外细胞培养方法研究大豆异黄酮对奶牛乳腺上皮细胞增殖及泌乳性能的影响。取对数生长期的奶牛乳腺上皮细胞,用无血清培养基培养24 h,使细胞同步化后分组试验。试验分空白对照组(0 mg/L大豆异黄酮)和添加不同浓度大豆异黄酮(1、10、100、1000 mg/L)组,培养48 h后,采用CASY 细胞计数仪检测细胞增殖能力与活力,高效液相色谱检测β-酪蛋白和乳糖,甘油三酯检测试剂盒检测甘油三酯的分泌情况。结果表明,与对照组相比,10、100、1000 mg/L大豆异黄酮组奶牛乳腺上皮细胞的增殖能力与活力显著增强(P<0.05);细胞分泌β-酪蛋白、乳糖和甘油三酯的能力也显著提高(P<0.05)。因此,添加10、100、1000 mg/L大豆异黄酮均能促进奶牛乳腺上皮细胞增殖及提高其泌乳性能,且呈一定的浓度依赖性。

Abstract: Effect of isoflavones on the proliferation and lactation of mammary epithelial cell of dairy cow were determined in vitro. The mammary epithelial cells during the logarithm growing period were cultured with serum-free medium for 24 h and synchronized. The experiments were assigned into 5 groups(0,1,10,100 and 1000 mg/L isoflavones).After 48 h treated with different concentration of isoflavones,the proliferations and viabilities of cells were determined by CASY cell count technology. The secretion of β-casein and lactose of cells were determined by high efficiency liquid chromatography(HPLC) and the secretion of triglyceride of cells were determined by triglyceride test kit. The results showed that 10,100 and 1000 mg/L isoflavones significantly improved dairy cow mammary epithelial cell proliferation(P<0.05) and the secretion of β-casein,lactose and triglyceride compared with the control group(P<0.05).Therefore,10,100 and 1000 mg/L of isoflavones could advance the proliferation and lactation of mammary epithelial cell of dairy cow,and it was concentration-dependent.

Key words: isoflavones; mammary epithelial cell of dairy cow; proliferation; lactation; high efficiency liquid chromatography
