| 基金项目： | 课题受山东省中医药科技发展计划项目(2009222)资助;课题名称:褐藻多糖硫酸酯对人肾小管上皮细胞间质转分化影响的实验研究 |
| 摘 要： | 背景:肾间质成纤维细胞体外研究时间点的选取多在72h以内,但对于体外长时间动态观察培养过程中成纤维细胞增殖及胶原分泌规律少见报道。目的:观察人肾间质纤维化来源的成纤维细胞体外增殖及胶原蛋白合成的规律。方法:采用组织块培养法获取、纯化并鉴定肾间质纤维化来源的人肾间质成纤维细胞,选取第3代对数生长期细胞用于实验。MTT比色法及Masson三色染色结合图像分析法分别检测体外培养第1,3,5,7,9天细胞的吸光度值和成纤维细胞胶原蛋白染色阳性细胞的平均吸光度值。结果与结论:肾间质成纤维细胞体外生长曲线呈"S"形,体外培养第3～5天为细胞倍增时间,随培养时间延长,胶原蛋白由线状分布转变成片状分布,其中以第3～5天增长最快(P<0.05)。结果证实,肾间质成纤维细胞在体外培养第3～5天增殖能力和胶原合成活性最强。 |
