Pathological change in isoprenaline-caused rat cardiac fibrosis model. A piece of the heart tissue from each rat in the ISO rat model was fixed with formalin, and then it was embedded in paraffin. Thin sections were cut and stained with hematoxylin and eosin (H&E) (a), Masson’s trichrome stain (b). Rats were grouped vehicle (control) rat hearts or ISO (fibrotic) rat hearts. Representative views from each group are presented. The numbers in the views represent the groups of rats in the experiments
