Fig 4 Electron micrograph (February 2004) shows increased amounts of mesangial basement membrane (mbm) material and obliteration of capillary loops (ocl). There were no electron-dense deposits in capillary loop basement membrane (clbm). Abbreviations: pc, podocyte; pcfp, podocyte foot processes. Bar = 2 μm.
