Myocyte diameter
WebJul 1, 1998 · In hearts from adult Swiss mice fixated in systole we found a left ventricular diameter of 2.0 mm, left ventricular wall thickness of 1.5 mm, and an intraventricular septum thickness of 1.3 mm ( Fig. 1 ). For C57BL/6J mice these data are 2.0 mm, 1.1 mm and 1.0 mm, respectively. WebThe myocyte diameter in both ventricular walls and septum in JVS mice was longer than that of the control mice. On electron microscopy, the percent of mitochondria in the myocyte was 66% in JVS mice, and 37% in control mice. The percent of lipid fraction in JVS mice was six-fold higher than that in control mice.
