Figure 9.
Talpid3 mutant glia scaffold is abnormal and insufficient for progenitor migration. (A–C) P5 dentate gyrus immuno-stained for GFAP and Sox2. Loss of GFAP fibres in the ML (ML) and radial fibres stretching through the GCL is seen in the mutant (Ta3fl/flNesCre). Sox2+ progenitors are evenly distributed across the glial scaffold in the control (Ta3fl/flNesCre). In the mutant (Ta3fl/flNesCre) many progenitors are found clustered on a single fibre (Solid arrow). Box indicates region of higher magnification. Scale bars: 75 μm (A), 25 μm (B, C).
