Newly born neuroblasts migrate from the SVZ to peri-infarct cortex after stroke. a–c, Cells double labeled (arrows) for DCX (red), BrdU (green), and overlap (yellow) in white matter (b), the white matter/cortical interface (a), and peri-infarct cortex (c) at day 7 after stroke after SVZ microinjection of BrdU. Three-dimensional confocal reconstructions of cells in b and c are presented as viewed in the x–z (bottom) and y–z (right) planes. d, e, Cells double labeled (arrows) for DCX (red) and GFP (green) migrate through peri-infarct cortex at day 7 after stroke after SVZ microinjection of lentivirus/GFP. f, Cells double labeled for DCX and GFP extending extensive local processes into peri-infarct cortex at day 14 after stroke after SVZ microinjection of lentivirus/GFP. Scale bars, 25 μm.
