Fig. 1From: Immune-complex glomerulonephritis in cats: a retrospective study based on clinico-pathological data, histopathology and ultrastructural featuresHistological and ultrastructural findings in cases of MGN (a, b) and MPGN (c, d). Masson’s Trichrome section of a glomerulus with moderate mesangial sclerosis and thickening of glomerular basement membrane associated to protein deposits (a). Electron microscopy shows sub-epithelial electron dense deposits in the GBM (arrows) (b). PAS section of a glomerulus shows remodeling of the glomerular basement membrane, mesangial interposition and mesangial matrix increase (c). Electron microscopy reveals immune complexes in the basement membrane associated with an increase of thickening (arrows) (d)Back to article page
