Hematoxylin/eosin staining, and immune stains for Ki-67 (proliferative marker) and WT-1 (podocyte marker) in negative control glomeruli and glomeruli with hyperplastic podocytes. Negative control glomeruli with A hematoxylin/eosin staining, B negative Ki-67 staining and C positive WT-1 staining in podocytes. Hyperplastic podocytes with hematoxylin/eosin staining (D and G), positive Ki-67 staining (E and H) and negative WT-1 staining (F and I) from two collapsing glomerulopathy cases.
