| Caption | Spongiform degeneration of the neonatal PikfyveGt(AT0926)Wtsi/PikfyveGt(AT0926)Wtsi (PikfyveBeta-geo/Beta-geo) mouse heart. Saggital sections of neonatal wild-type (WT) and homozygous mutant mice stained with H&E. The atria (At), ventricles (V), and lung (L) of WT littermates exhibit normal morphology. At higher magnification, atrial and ventricular myocytes strongly stain with H&E. There is no apparent vacuolation. Homozygous mice have reduced H&E staining of atrial myocytes consistent with reduced myofibrillar content. In the homozygous mutants, both atria and ventricles have vacuoles (arrows), with a high level of vacuolation in the atria. Smaller vacuoles (arrowheads) give the myocytes (identified by heavily stained myofibrils (white arrow)) a foamy appearance. | ||||
