Three months later, autologous CSCs (n=11) or vehicle (n=10) were infused into the infarct-related artery. At this time, all indices of left ventricular (LV) function were similar in control and CSC-treated pigs, indicating that the damage inflicted by the infarct in the 2 groups was similar; 1 month later, however, CSC-treated pigs exhibited significantly greater LV ejection fraction (echocardiography) (51.7\u00b12.0% versus 42.9\u00b12.3%,\n              <jats:italic>P<\/jats:italic>\n              &lt;0.01), systolic thickening fraction in the infarcted LV wall, and maximum LV dP\/dt, as well as lower LV end-diastolic pressure. Confocal microscopy showed clusters of small \u03b1-sarcomeric actin\u2013positive cells expressing Ki67 in the scar of treated pigs, consistent with cardiac regeneration. The origin of these cycling myocytes from the injected cells was confirmed in 4 pigs that received enhanced green fluorescent protein \u2013labeled CSCs, which were positive for the cardiac markers troponin I, troponin T, myosin heavy chain, and connexin-43. Some engrafted CSCs also formed vascular structures and expressed \u03b1-smooth muscle actin.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Intracoronary infusion of autologous CSCs improves regional and global LV function and promotes cardiac and vascular regeneration in pigs with old myocardial infarction (scar).
