概要 | Background-CXC-chemokine receptor 4 (CXCR4) regulates the retention of stem/progenitor cells in the bone marrow (BM), and the CXCR4 antagonist AMD3100 improves recovery from coronary ligation injury by mobilizing stem/progenitor cells from the BM to the peripheral blood. Thus, we investigated whether AMD3100 also improves recovery from ischemia/reperfusion injury, which more closely mimics myocardial infarction in patients, because blood flow is only temporarily obstructed.Methods and Results-Mice were treated with single subcutaneous injections of AMD3100 (5 mg/kg) or saline after ischemia/reperfusion injury. Three days later, histological measurements of the ratio of infarct area to area at risk were smaller in AMD3100-treated mice than in mice administered saline, and echocardiographic measurements of left ventricular function were greater in the AMD3100-treated mice at week 4. CXCR4(+) cells were mobilized for just 1 day in both groups, but the mobilization of sca1(+)/flk1(+) cells endured for 7 days in AMD3100-treated mice compared with just 1 day in the saline-treated mice. AMD3100 upregulated BM levels of endothelial nitric oxide synthase (eNOS) and 2 targets of eNOS signal |
