Figure Legend Snippet: (A) Ai9 is seen in the cortical hem and its derivatives in an E12.5 control and Lmx1aCre; β-Catenin GOF brain. (B) Reelin staining in the same section as (A). (C) TRP73 staining at E14.5 co-localizes with Ai9 in the control but is undetectable in the β-Catenin GOF brain. (D) Genes enriched in CR cells are downregulated in midline tissue β-Catenin GOF brains at E14.5. (E, F) Reelin, βIII-Tubulin and NEUN staining is seen in Ai9+ cells in control brains (arrowheads). In β-catenin GOF brains there is no detectable Reelin (open arrowheads) (E) but βIII-TUBULIN and NEUN staining is seen in Ai9+ cells. (G, J) UMAPs representing tdTomato+ cells from E14.5 control and β-catenin GOF midline, color-coded by cell type (G); by age (H); by genotype (I); showing the expression of Wnt3a, Reln and tdTomato (J). (H) Heatmap of scaled expression of top 10 differentially expressed genes in control and β-Catenin GOF neurons. (I) Dot plots showing scaled expression levels of CR cell enriched genes in control and β-Catenin GOF neurons. Scatterplot in (D) displays Mean ± SEM. Statistical test(D): Multiple Mann-Whitney Tests; p < 0.0001; *p < 0.05; **p < 0.01; ***p < 0.001; ns if p value > 0.05. For (A-C, E-F), N ≥ 3 brains (biologically independent replicates); for (D) N=6 (control), 7 (GOF) biologically independent replicates. Scale bars: 100 μm (all images in A, B, C, E and F).
Techniques Used: Control, Staining, Expressing, MANN-WHITNEY, IF-P
Figure Legend Snippet: (A) UMAPs from representing tdTomato+ cells from control and β-Catenin GOF, color-coded by cell type; by genotype; and by pseudo-differentiation trajectory derived from Monocle3. (B) Normalized mRNA expression of Pax6, Eomes/Tbr1, Neurog2, Neurod2, Dcx and Tbr1 across the pseudo-differentiation axis for control (blue) and β-Catenin GOF (red). Thick lines represent Loess smoothed curves. (C) TBR2 staining is seen in Ai9+ cells in controls (arrowheads) but not in β-Catenin GOF brains. Dashed lines mark the ROIs in which TBR2+Ai9+ cells were quantified. (D) The Eomes and Foxj1 expression trajectory along the pseudo-differentiation axis in control neurons (E) Ai9 reporter expression at E12.5 comparing Lmx1a Cre and Foxj1 Cre activity. Foxj1 Cre is not active in hem progenitors but is seen in CR cells and the choroid plexus epithelium. (F) Genes enriched in CR cells are unchanged in midline tissue of Foxj1Cre; β-Catenin GOF brains at E14.5. (G) TRP73 and REELIN staining co-localizes with Ai9+ cells in the hippocampal fissure in both control and Foxj1Cre ; β-Catenin GOF brains at E16.5 and E18.5. Scatterplots in (C) and (F) display Mean ± SEM. Statistical test (C): Shapiro-Wilk normality test, followed by Welch’s two sample t-test, (F) Multiple Mann-Whitney Tests; p < 0.0001; *p < 0.05; **p < 0.01; ***p < 0.001; ns if p value > 0.05. For (C), N=3 (biologically independent replicates), (E), N=5 (biologically independent replicates), (F), N=6 (biologically independent replicates), (G), N=3 (biologically independent replicates). Scale bars: 100 μm (all images in C, E and G).
