FGF-9 Inhibits Infarct and Fibrosis in the Post-MI Diabetic Myocardium.

<p><b>A-F</b>: Representative images of Masson’s trichrome stained sections are shown depicting infarct (<b>A-C</b>) and interstitial fibrosis (<b>D-F</b>) for control and experimental groups 2 weeks post-MI. Single arrows represent infarcted myocardium. Double arrows represent interstitial fibrosis. <b>G</b>: Histogram of quantitative infarct size analysis suggests a significant decrease in infarct size in the MI+FGF-9 group compared to the MI group. <b>H</b>: Histogram of mean left ventricular cardiac myocyte cross sectional interstitial fibrotic (IF) area (mm²). n = 5–8 animals/group. *p<0.05 vs. sham and #p<0.05 vs. MI.
