The histology for the MI + MPIO group further showed the colocalization of Prussian blue and F4/80 staining, indicating that an appreciable amount of MPIO was incorporated in macrophages (Fig. 3c,d). No F4/80-positive or Prussian blue�Cstained http://www.selleckchem.com/products/Maraviroc.html cell was observed in the Sham + MPIO heart. These results suggested that a large number of MPIO-labeled macrophages mobilized, infiltrated, and engrafted into the infarcted area of the heart, thereby causing distinguishable signal attenuation in the T2*-weighted MRI. CNR at the MI site was calculated to quantify the infiltration of MPIO-labeled inflammatory cells into the MI site. The negative CNR values indicated hypointensities around the MI site (Fig. 4a). The more negative the CNR was, the more attenuated the signal at the MI site relative to the normal myocardium. The continuous CNR attenuation in MI + MPIO group suggested ever-increasing MPIO-labeled inflammatory cell infiltration. The CNR decreased dramatically within 1 week post-MI and changed only minimally between 7 days and 14 days post-MI. The CNR at the corresponding sites http://www.selleck.cn/products/Paclitaxel(Taxol).html for the two control groups did not show large variation over the experiment course. A two-way repeated-measures analysis of variance showed a significant difference in CNR values between the three treatment groups (P http://www.selleckchem.com/products/pirfenidone.html among the three groups. The CNR represents the difference of signal intensity between the MI site and normal myocardium. Therefore, these results suggest that not only a global infiltration of MPIO-labeled cells occurred at the MI site but also possibly a redistribution of MPIO-labeled cells between the MI site and normal myocardium. The redistribution notion was excluded, however, since a relatively stable signal intensity was observed in the normal myocardium over the course of each experiment. Thus, these CNR data suggest a global MPIO-labeled inflammatory cell migration and infiltration into the MI site. Figure 3a illustrates the anatomic morphologic changes occurring 7 days after the MI. LVEF, a standard clinical measurement, was used to evaluate the resulting alterations in post-MI cardiac performance. Ventricular hypertrophy quickly develops following an MI in the murine model. LVEF in the MI group decreased dramatically within 1 week post-MI and then somewhat stabilized; the LVEF in the sham group did not alter much over the course of the experiment (Fig. 4b). A two-way repeated-measures analysis of variance showed a significant difference in LVEF between the three treatment groups (P
