Electron microscopy image used to measure volume density of glomerular components. (A) Image of glomerular profile showing podocytes (Podo), mesangium (Mes), capillary lumen (CL), and Bowman's space (BM). (B) Image of a glomerular profile with counting grid. Glomerulus was defined as the minimal string polygon surrounding the glomerular tuft. The number of grid points falling on each of the four defined glomerular components was counted and used to calculate the volume density of each component. Scale bar = 10 μm.
