摘要
目的：建立便捷，成熟的新生大鼠心肌细胞体外培养方法。方法：本实验对常用的培养方法加以改进．采用胰蛋白酶及Ⅰ型、Ⅱ型胶原酶共同消化法，分离新生大鼠心肌细胞，并对体外培养的心肌细胞的存活率、活力及纯度进行鉴定。结果：分离的心肌细胞存活率为96％，培养3d后有60-80％的细胞开始搏动，搏动频率平均50次／min，心肌细胞纯度在75％以上。结论：本实验建立的新生大鼠心肌细胞体外培养方法是成熟，可靠的。
Objective： To establish a convenient and mature method of isolation and culture of cardiomyocytes in neonatal rat. Methods： Cardiomyocytes of neonatal rat were isolated in trypsin and collagenase. Then the livability, energy and the purity of cardiomyocytes were identified. Results： The livability of cardiomyocytes was 96 % ; 60%- 80% beating cardiomyocytes were observed and the beating frequency of cells was 50 beats/min after 3 days. The purity of cardiomyocytes was 75 %. Conclusion： This method of isolation and culture of cardiomyocytes in neonatal rat was mature.
