Figure 3

Microphotographs showing rat facial nuclei submitted to immunohistochemistry of different markers. Animals were submitted to the transection of the facial nerve (with amputation of the nerve stumps) (B, D, F, H) or submitted to a sham operation (A, C, E, G), 7 days before the sacrifice. The figures A-D show glial fibrillary acidic protein (GFAP) immunoreactivity, figures E-H show neurofilament (NF) ones in coronal sections of the facial nucleus of rats. The figures C, D and G, H represent higher magnification of areas inside the nuclei showed in figure A, B and E, F, respectively. Arrowheads show GFAP immunoreactive astrocytes and arrows point to NF immunoreactive neurons. The GFAP immunoreactivity is increased in the cytoplasm and processes of astrocytes of the facial nucleus of the lesioned rats (B, D). Furthermore, NF immunoreactivity is increased in the cell body of neurons and neuropil of the facial nucleus of the lesioned rats (F, H). Bars = 100 μm (E, F), 50 μm (A, B, G, H), 25 μm (C, D).
