Early born neuronal populations are overproduced in Sall1−/− mice. (A,B) Tuj1 (green) staining identified an increase in preplate size at E12.5 in Sall1-deficient animals (B) compared with controls (A). (C) Quantification of cortical cell number at E11.5 and E12.5. *, P<0.05; **, P<0.01. (D,E) CSPG (red) immunostaining of the subplate (bracketed region) and marginal zone identified an increase in these structures in Sall1−/− mice (E) compared with controls (D) at E14.5. Note: CSPG is also expressed by the meninges at the pial surface. (F,G) Reelin (red) immunostaining identified an increase in Cajal-Retzius cells in Sall1−/−mice (G) compared with controls (F) at E14.5. (A,B,D–G) Sections are counterstained with DAPI (blue). PP, preplate; PC, progenitor population; IZ, intermediate zone; SP, subplate; CP, cortical plate; MZ, marginal zone; P, pial surface. Scale bar: 100 μm (A,B); 200 μm (D,E); 400 μm (F,G).
