Abstract

Contractile cardiomyocytes in various parts of the heart differ in shape, size, ploidy, and other parameters. However, it is not known whether their population is heterogeneous within each heart chamber. In this paper, dry weight and ploidy of cardiomyocytes were estimated in different parts of rat left ventricle. It was found that the dry weight of cardiomyocytes in medial part of left ventricular anterior wall is higher than in other parts of the ventricle. Cardiomyocyte ploidy is the same in different regions of the left ventricle.

摘要

心脏不同部位的收缩性心肌细胞在形状、大小、倍性和其他参数方面存在差异。然而，每个心腔内的心肌细胞群体是否存在异质性尚不清楚。在本文中，对大鼠左心室不同部位的心肌细胞干重和倍性进行了评估。结果发现，左心室前壁内侧部分的心肌细胞干重高于心室的其他部位。左心室不同区域的心肌细胞倍性相同。
