General pathological changes of in situ and transplanted hearts with and without MI. Animals were divided into the following groups: in situ without MI (I-sham group), in situ with MI (I-infarct group), transplantation without MI (T-sham group), and transplantion with MI (T-infarct group). A: representative images of wheat germ agglutinin (WGA)-stained (FITC labeled) noninfarcted areas (top) and gross inspection of PSR-stained heart transverse sections (bottom). B: statistical comparisons of cardiomyocyte cross-sectional areas derived from WGA staining. *P < 0.05 by intragroup comparisons with data of 3 days; §P < 0.05 by intergroup comparisons (i.e., I-infarct vs. T-infarct groups and I-sham vs. T-sham groups) between data from the same time point.
