Histological and myocardial fibrosis analyses. (A) Gallego’s trichrome staining (scale bar = 100 μm) of remote, border, and infarct tissue sections showing collagen deposition (green), healthy muscle (yellow), and nuclei (pink). (B) Masson’s trichrome (scale bar = 100 μm) in MI heart sections, staining collagen scar in light green and healthy myocardium in Ponceau fuchsin. (C) Representative images of fibrosis analysis with Picrosirius red staining in remote and infarct myocardial zones under bright field, displaying collagen (red) and cardiac muscle (pink), and under polarized light showing collagen I (red/yellow) and collagen III (green) fibrils in the same tissue sections (scale bar = 50 μm).
