Immunodetection of proliferation, progenitor and neuronal markers, and BrdU was carried out as previously described7 (link),93 (link). Primary antibodies used were rabbit anti-DCX (1:750, Cell Signaling Technology Inc.), goat anti-DCX (1:250, Santa Cruz Biotechnology), rabbit anti-Ki67 (1:250, Abcam), mouse anti-NeuN (1:300, Millipore), mouse anti-GFAP (1:8000, Sigma), goat anti-Sox2 (1:2000, R&D Systems), rat anti-BrdU (1:300, Abcam). As secondary antibodies Alexa (1:500, Molecular Probes) and DyLight (1:500, Abcam) conjugated antibodies were used. NucBlue (Life Technologies) was used as nuclear dye. Slices were mounted on gelatin-coated slides with Fluoromont-G (Electron Microscopy Sciences).
