Figure 3 (A–C) Podocalyxin (pod) and ezrin in a renal glomerulus of a 10‐year‐old child presenting with diffuse mesengial proliferation. The large inset (magnified from the small inset) shows the granular pattern of podocalyxin distribution. Note the largely overlapping immunofluorescence of both antibodies in podocytes (arrow; yellow in C). In addition, ezrin is located on the apical cell membranes (probably microvilli) of proximal tubuli and in parietal glomerular cells (Bowman's capsule; arrowhead in (B)). (C) Scale bar 20 µm.
