A fraction of 1% CXCR4+/CD11b+/CD206+ cells in a total-heart non-myocyte suspension after MI and DMOG treatment would mean around 7 × 105 (10 × 7 × 106 × 0.01) CXCR4+/CD11b+/CD206+ cells exceeding the numbers of injected reparative M2-like macrophages (2 × 105) by far. This evidence concerns the gene CXCR4 and myocardial infarction.
