Decreased Expression of Semaphorin3A/Neuropilin-1 Signaling Axis in Apical Periodontitis

Figure 2

Sema3A/Nrp1 were decreased in rat periapical lesions. (a) Immunohistochemical staining of Sema3A-positive cells in rat periapical lesions at different stages. (b) Immunohistochemical staining of Nrp1-positive cells in rat periapical lesions at different stages. Cells positive for Sema3A/Nrp1 are indicated with arrows. Observation was performed under ×400 magnification, scale bar = 5 μm.
