(A) E15.5 WT and Prdm16 cKO cortical sections
immunostained for PAX6, TBR2 and pH3. The ventricular zone (VZ) and
subventricular zone (SVZ) are indicated. Arrows show examples of
TBR2+/pH3+ cells in the SVZ of WT cortex. Top plot
shows quantification of PAX6+/pH3+ and
TBR2+/pH3+ cells. Lower plot indicates the number of
TBR2+ cells (n=5).
(B) Cell cycle exit analysis. Arrows indicate examples of
KI67+/EdU+ cells. The fraction of
KI67−/EdU+ cells relative to EdU+
cells was quantified (n=5).
(C) Clonal analysis of radial glia. The number of cells per clone was
analyzed. Pie charts indicate the percentage of clones containing cells with
multipolar morphology (arrow). Data represents mean ± SE; statistical
analysis is unpaired Student’s t test (*p < 0.05, **p <
0.01, *** p < 0.001; n.s., not significant). Scale bars: 50 μm
(A), 20 μm (B, C).
