Figure 2: FGF23 is present in cardiomyocytes of mice with a cardiac restricted overexpression of the macrophage chemoattractant MCP- 1. (A) Confocal images and statistical analysis of FGF23 in 6-month-old mouse myocardial tissues. Con indicates healthy wild-type controls and iHF represents the MCP-1 overexpressing strain which develops ventricular dilatation up to 6 months and dies because of heart failure. (B) RT-PCR of FGF23 from human tissue samples. DCM and ICM indicate dilated and ischemic cardiomyopathy, respectively.
