Scale bar = 1 μm. b Dark and shrinking epithelial cell (EC) losing contact with neighbouring cells (arrow). Scale bar = 1 μm. c Epithelial cell flattened surface devoid of surface specializations (arrows). Scale bar = 0.5 μm. d Disrupted structure of intercellular junctions (arrowheads). Scale bar = 0.5 μm. e Thickened basement membrane (white asterisk) of blood capillaries. Scale bar = 1 μm. f Extracellular matrix containing abundant amorphic substance (black asterisk) and fragmented collagen fibers (CF). Scale bar = 2 μmBack to article page
