Fig. 2

Central fibrosis area (CFA) consisted of fibrillar collagens in addition to matrix collagens. a–d Immunostaining for collagen I (a), collagen III (b), collagen IV (c), and collagen VI (d) (magnification × 400). Collagen III, one of the major fibrillar collagens, was present in CFA (arrows) in addition to non-fibrillar collagens, collagens IV and VI. Collagen I was weak-positive. e Electron microscopy showed enrichment of fibrous collagens (right side) in CFA, distinguishing them from mesangial matrix components in the mesangium (left side) (magnification × 6000)
