Fig. 2From: High fat diet altered cardiac metabolic gene profile in Psammomys obesus gerbilsRepresentative Masson Trichrome-stained myocardial sections from Psammomys obesus gerbils fed with normal diet (a, b) or with high fat diet (c-f) during 16 weeks. Trichrome Masson staining was performed to detect fibrotic areas (collagen fibers stained in green; indicated by arrows in a-e). Myocardial sections were obtained at 400-fold (a-e; scale bars: 50 μm) and 1000-fold (f; scale bar: 20 μm) magnification. In animals fed with normal diet, cardiac cells were arranged orderly, with structured cardiac muscle fiber organization and little collagen fiber deposit (a, b). In 16-week high fat diet fed animals, Trichrome Masson-stained myocardial sections showed diffuse fibrosis (mostly in perivascular areas; c and d) and lipid deposit (f)Back to article page
