To assess the status of catecholamine storing vesicles, immunohistochemistry was performed for chromogranin A in Rb1F2/F2:Trp53F2-10/F2-10 (A) and Rb1F2/F2:Trp53F2-10/F2-10:TEC1 (B) and synaptophysin in Rb1F2/F2:Trp53F2-10/F2-10 (C) and Rb1F2/F2:Trp53F2-10/F2-10:TEC1 (D) adrenal medullas. Scale bar, 50 µm. Electron micrographs of Rb1F2/F2:Trp53F/F (E; original magnification, x50,000) and Rb1F2/F2:Trp53F/F:TEC1 (F; original magnification, x50,000) chromaffin cells showing the overall density and morphology of vesicles (arrow). H&E staining of Rb1F2/F2:Trp53F2-10/F2-10 (G) and Rb1F2/F2:Trp53F2-10/F2-10:TEC1 (H) heart sections that shows structural remodeling of the Rb1F2/F2:Trp53F2-10/F2-10:TEC1 hearts (as indicated by arrows).
