SOX2 and ischemia: ↑ BrdU in 85% of lesioned cortex at 7 days post ARA-C ↑ BrdU/NeuN, BrdU/Hu in ischemia cerebral cortex ↑ SOX-2 at 30 days post-ischemia – ventricular region AAV-FGF group ↑ BrdU/NeuN, BrdU/Hu compared to non-FGF group 2× ↑ SOX-2 at 30 days post ischemia ↓BrdU/GFAP at 30 days post-ischemia
