OSM Enhances Angiogenesis and Improves Cardiac Function after Myocardial Infarction

Figure 3

OSM treatment attenuated cardiomyocyte apoptosis after MI. (a) Representative digital micrographs showing cardiomyocyte apoptosis in the border zone of all groups of mice. Bar: 25 μm. (b) Western blot assay of cleaved caspase 3 and caspase 3 in the border zone of the six groups of mice. (c) Quantitative analysis of cardiomyocyte apoptosis after MI in counts/high-power field (HPF). (d) Quantitative data of the expression of cleaved caspase 3 in the six groups of mice. The values are means ± SD. versus WT group, versus WT + MI group, and versus Oβ−/−S group. in each group.
