Figure 3. Reduce expression of Vimentin, Pax6, and proliferation suggest a loss of radial glial stem cell in Jag1 mutants.
(A-B) RNA In situ hybridization using a Vimentin probe and (C-D) Immunohistochemistry using anti-Pax6 antibody on sagittal sections show thinner expression in Jag1 mutant. Quantification of Vimentin (I) and Pax6+ (J) labeling shows decrease expression in mutants compared to control. Antibodies against p-HH3 (E-F, K) and Ki67 (G-H, L) show decrease expression in the VZ. Scale bar = 200μm. All graphs show means ± SEM. *, p<0.05; **, p<0.01; ***, p<0.001. Cx, cortex; dLGE, dorsal lateral ganglionic eminence.
