a Jones silver staining shows holes in the glomerular basement membrane (circle). Original magnification × 630, scale bar represents 50 μm. b Electron microscopy shows the ultrastructural correlate to these holes: infolding of the podocyte cytoplasm into the glomerular basement membrane, most of them with underlying densities (red arrows). This finding is characteristic for the podocyte infolding glomerulopathy (PIG). Transmission electron microscopy, original magnification × 10000, scale bar represents 1000 nm)
