The gene changed heart muscle cells -- called cardiomyocytes -- into natural pacemaker cells.

该基因将心肌细胞（称为心肌细胞）转变为天然起搏细胞。

Their method involves placing heart muscle cells, cardiomyocytes, onto biocompatible gels with structural color properties.

他们的方法涉及将心肌细胞、心肌细胞置于具有结构颜色特性的生物相容性凝胶上。

They have the ability to differentiate into myocytes with structural and functional properties of cardiomyocytes and into many other cell types.

它们具有分化成具有心肌细胞的结构和功能特性的肌细胞以及许多其他细胞类型的能力。

That's due to sort of disorganized ion movement within the cardiomyocytes, and it could also be due to a disrupted electrical conduction system within the heart.

这是由于心肌细胞内某种杂乱无章的离子运动引起的，也可能是由于心脏内的电传导系统被破坏了。

First, it's super important to remember that in each case, the injury to cardiomyocytes isn't permanent, meaning it's reversible and the cardiomyocytes don't die (which is how this differs from myocardial infarction).

首先，务必记住每种情况下，心肌细胞损伤不是永久性的，即可逆，心肌细胞不会死亡；这也是与心肌梗死的区别。
