GFAP+ NSCs and DCX+ neuroblasts in SVZ are not labeled with EYFP. A, Fluorescent micrographs depicting the absence of EYFP expression in GFAP+ (red) neural stem cells of both dorsolateral and ventral tip of SVZ on day 10 after TM. Boxed area is shown at higher magnification in A1–A3. B, Consistently, no DCX++ (red) neuroblasts in SVZ expressed EYFP. B1–B3, Higher-magnification images of boxed area in B. CC, Corpus callosum; LV, lateral ventricle. Scale bars: A, B, 50 μm; B3, 30 μm.
