Figure 5.

Echocardiographic evaluation of cardiac function. Histograms representing ΔLVEF (A) and ΔLVFS (B) from baseline to before sacrifice (30 days). Differences between groups were globally estimated using one-way analysis of variance. (C): Representative M-mode echocardiographic images in the parasternal long axis view. Abbreviations: control-MI, myocardial infarction induced but no treatment; ΔLVEF, change in left ventricular ejection fraction; ΔLVFS, change in left ventricular fractional shortening; MI-fibrin, myocardial infarction treated with fibrin alone; MI-UCBMSC, myocardial infarction treated with umbilical cord blood mesenchymal stem cells; Sham-UCBMSC, no myocardial infarction but implantation of fibrin-cell patch.
