Fig. 3From: Role of NOD2 and hepcidin in inflammatory periapical periodontitisRepresentative images of the immunohistochemical expression of hepcidin in periapical tissue. Hepcidin-positive staining could be observed in induced rat periapical inflammatory lesions. Rat periapical tissue showed a negative observation of hepcidin in control group. Hepcidin was expressed on the ECM in periapical lesions. e Quantitative analysis of the hepcidin expression. Original magnification: ×4 (a and c), ×40 (b and d)Back to article page
