发布时间:2018-07-24 15:40
【摘要】:目的优化SD乳鼠心肌细胞和心肌成纤维细胞的体外分离培养的条件和方法。方法分别用胰酶、Ⅱ型胶原酶依次消化分离心肌组织,再通过两次差速贴壁分离法分别收集、培养乳鼠心肌细胞和心肌成纤维细胞。光学显微镜下分别观察心肌细胞和心肌成纤维细胞的基本形态特征的变化,原代心肌细胞行心肌肌钙蛋白免疫荧光鉴定,而心肌成纤维细胞则用第2代行波形蛋白免疫荧光鉴定。结果心肌细胞在2~4 h开始贴壁生长,12~24 h贴壁速率大幅增加,并出现自发性搏动,48~72 h心肌细胞粘合成簇,细胞成活率,纯度均达95%以上;心肌成纤维细胞第2~4代细胞生长良好,纯度高达98%以上。结论此种方法可得到产量大,纯度高,活力好的心肌细胞和心肌成纤维细胞,为心血管疾病的基础与临床研究提供了理想的实验模型。
