Effect of rotenone on astrocytes in cervical and lumbar SC. Representative photomicrographs of double immunofluorescent staining for TUNEL (red) and GFAP (green) a marker for astrocytes, performed in cervical and lumbar SC coronal slices (5 μm). In cervical and lumbar slices from SC, GFAP-positive astrocytes did not show TUNEL-positive IR in control or rotenone administered rats. GFAP-immunostaining was enhanced in experimental rat SC. Images taken at 200x magnification (n≥4).
