Figure 2 (A) Left ventricular (LV) voltage map in a healthy animal in which three percutaneous catheter-based injections of iron-loaded myogenic precursor cells (MPC) were performed at the LV apex (black dots). (B) Corresponding magnetic resonance imaging 90 min after MPC implantation (long axis and apical short axis black-blood T2-weighted turbo spin echo imaging) showing the three sites of injection (arrows) on the four-chamber view into normal myocardium with good anatomical agreement (two sites of injection were intersected on the two-chamber view, arrows). (C) Corresponding hematoxylin (upper panel) and Perls stain (lower panel) of implanted iron-loaded MPC into healthy apical LV myocardium (x100).
