摘要
本研究旨在建立一套可靠的窦房结细胞取材分离、纯化培养技术。取Wistar乳鼠的窦房结组织进行原代细胞培养 ,随机分两组 :常规方法组与差速贴壁结合 5 溴脱氧尿核苷 (BrdU)处理组。结果 :①在培养的窦房结细胞中观察到三种不同形态的细胞 ,即梭形细胞、三角形细胞与不规则形细胞。其中梭形细胞最多 ,且形态结构与电生理特征符合窦房结起搏细胞的特点。三角形细胞与心房肌三角形细胞特征相似。②常规方法培养中窦房结梭形细胞所占比例为 45 % ,而差速贴壁技术结合BrdU处理的纯化培养中梭形细胞达 6 8%左右 (P <0 .0 1)。结论 :用差速贴壁结合BrdU处理的纯化培养可明显提高窦房结梭形细胞的比例 ,是一种可靠的窦房结细胞培养技术
