Left ventricular ejection fraction (EF%) in MI (33.5 ± 4.9), MSCs (42.4 ± 2.0), Ad-HGF-MSCs (44.2 ± 2.6), SMHs-MSCs (52.3 ± 2.9), and Ad-HGF-SMHs-MSCs (62.1 ± 3.0) groups was significantly decreased (P < 0.01) compared to the sham group (79.7 ± 3.4). This evidence concerns the gene HGF and myocardial infarction.
