Presence of glial cells in the substantia nigra pars compacta (SNc). Representative merged confocal micrographs showing the presence of NG2+ cells (green) with TH+ cells (red, top row), with OX42+ cells (red, middle row), and with GFAP+ cells (red, bottom row) at day 30 after lesion, L30 (A) and at day 15 after transfection with 15 days of lesion, L15T15 (B). Graphs showing the mean fluorescence intensity (MFI) for NG2 (C), OX42 (D) and GFAP (E). The scale bars = 20 μm are common for all the micrographs. ns = not significant. ***P < 0.001 when compared with the intact condition. £ = P < 0.001 when compared with L30. One-way ANOVA with Newman-Keuls post hoc test. n = 4 different rats for each condition. GFAP, glial fibrillary acidic protein; NG2, Neuron/Glial type 2.
