Additional file 1: Figure S1. of Inhibition of Oct 3/4 mitigates the cardiac progenitor-derived myocardial repair in infarcted myocardium

Showing immunostaining signals for Ki67, phosphorylated histone-3 and EdU from sham myocardium. Representative immunostaining images from sham hearts. α-Actin (green) was used to stain cardiomyocytes. Ki67 (red), PH3 (red), and EDU (red) were used to examine myocyte proliferation. (Staining results from other groups are presented in Fig. 3f–k.) Scale bar: 100 μm. The detailed procedure is described in Materials and methods. (TIF 365 kb)
