Differences of immunohistochemical profiling of MOC-31, caveolin-1, connexin-43, Ki-67 in ameloblastic fibroma, ameloblastic fibrodentinoma, ameloblastic fibro-odontoma, and odontomas

Figure 4 Immunoexpression of Ki-67 in ameloblastic fibroma, ameloblastic fibro-odontoma, and odontoma. A: Ameloblastic fibroma with nuclear positivity in 5% of cells with staining in ameloblastic cells; B: Ameloblastic fibro-odontoma with immunoexpression in 4.5%, involving both ameloblasts and odontogenic mesenchymal cells; C: Odontoma, which was negative for protein immunoexpression. Immunohistochemistry, Ki-67, A-C: × 20.
