IHC staining (400x) for number of the vasa vasorum and numbers of CD34+, Flk-1+, Sca-1+ cells in left ventricular myocardium (n = 8). G) The number of vasa vasorum (red arrows) was remarkably higher in normal control than in obesity. * vs. normal, p < 0.0001. H) The number of CD34+ stain cells (yellow arrows) was significantly higher in normal control (A) than in obesity (B). * vs. normal, p < 0.001. I) The number of Flk-1+ cells (green arrows) was notably higher in normal control (C) than in obesity (D). * vs. normal, p < 0.001. J) The number of Sca-1+ cells (pink arrows) was notably higher in normal control (E) than in obesity (F). * vs. normal, p < 0.001. MA, MB, MC, MD, MA, and MAF indicated dotted line area (i.e., the vasa vasorum) was magnified for 1000x. Scale bars in left lower corner represent 20 μm.
