Histological changes and tenascin-C expression in the kidneys of diabetic rats. A: Hematoxylin-eosin staining; B: Periodic acid-Schiff staining (400 ×); C: Immunohistochemical staining; D: Pathological scoring of tenascin-C (TNC). Scale bar: 20 μm. Representative immunohistochemical images and immunohistochemical scores for TNC in renal section are shown. aP < 0.05 compared with the NC control group. NC, n = 6, DN, n = 6. NC: Normal rat renal section; DN: Diabetic rat renal section; HE: Hematoxylin-eosin; PAS: Periodic acid-Schiff; TNC: Tenascin-C.
