Figure 3. Clonally dominant cortical cardiomyocytes.

Figure 3

a–c, 6 weeks post-fertilization (wpf) ventricular surface (a, b) and confocal slice (c), indicating cortical (Cor, arrow), primordial (Pr, arrowhead), and trabecular (Tr) muscle. d–g, 8 wpf ventricular surface indicating a large green basal clone (d–f), and section indicating 3 muscle types (g). h, 90 dpf ventricular surface, showing only a few large cortical clones. i, 90 dpf ventricular section. j, %Surface area occupied by 90 dpf clones (56 clones, 10 ventricles); basal clones representing each ventricle are circled. k, Surface clones per ventricle (n=10). Scale bars, 50 μm (a–g); 100 μm (h, i)
