Acute Myocardial Infarction Reduces Respiration in Rat Cardiac Fibers, despite Adipose Tissue Mesenchymal Stromal Cell Transplant

Figure 1

Electrocardiogram (ECG) records and infarct size after acute myocardial infarction (AMI) in female rats. (a) Representative ECG profiles (as analyzed in bipolar lead I) showing no alterations in the Sham group (upper graph), while the ECG of infarcted rats (lower graph) showed a pathological Q wave (empty arrow) and an ST-elevation (filled arrow). Calibration is seen in (a), right side; (b) bar graph showing the infarct size (%) in the PBS treatment and AD-MSC treatment groups after AMI; # in relation to the Sham group. (c) Representative images from the hearts stained with 2,3,5-triphenyltetrazolium from the Sham group and 24 h and 8 d after myocardial infarction. Noninfarcted, viable tissue is stained in red, whereas the infarcted region is unstained (white). Scale bar: 0.4 cm.
