A–C Bright-field images of isolated adult zebrafish hearts, 2 years of age: wild-type fish, remodeled plna R14del mutant heart and non-remodeled plna R14del heart. D–F Hematoxylin and eosin staining of the three conditions to identify nuclei, with zoom-in at indicated regions. G–I Picro-sirius red staining of collagen deposition for the three conditions, collagen fibers are shown as red staining. J–L Oil Red O staining for fat/lipid of the three conditions. All stainings were performed on WT n = 3, plna R14del n = 3, two experimental replicates. Zoom-in of each indicated region is included. Images were taken at a magnification of ×20. Scale bars are 200 µm for whole-heart tile scans and 50 µm for zoom-in regions. A atrium, V ventricle, BA bulbus arteriosus.
