Figure Lengend Snippet: Fig. 4. AS3MTd2d3 expression perturbs NSC fate and spindle orientation with evidence of centrosome localization. (A) Overview of the experimental approach. Cortical cells were isolated from E15.5 littermate control or AS3MTd2d3-Tg mice across two biological replicates. (B) UMAP embedding of integrated scRNA-seq cell type annotation (n = 30,246). (C and D) Trajectory inference and pseudo-time analysis between control and AS3MTd2d3-Tg. (E) E15.5 brain sections stained as indicated. in utero electroporation at E13.5 and BrdU injection at E14.5. (F and G) Quantification of the percentage of RFP+BrdU+Sox2+ or RFP+BrdU+Tuj1+ cells among the RFP+BrdU+ cells (Control, n = 5; AS3MTd2d3, n = 7). (H) Subcellular localization of Flag-AS3MTfull or Flag-AS3MTd2d3 in E14.5 brain sections, stained as indicated. (I) Quantification of the centrosome integrated intensity marked by γ-tubulin (AS3MTfull, n = 7; AS3MTd2d3, n = 18). (J) E14.5 brain sections stained as indicated. in utero electroporation at E13.5. Dotted line indicates orientation of the sister chromatids (α). (K) Quantification of the percentage of cortical progenitors within each 30° interval (Control, n = 6; AS3MTd2d3, n = 6). Scale bars, (E) 20 μm and [(H) and (J)] 10 μm. Bar graphs show the means ± SEM. Statistical significance is defined by unpaired two-tailed t tests for Sox2 and Tuj1 staining analysis, Welch’s t test for centrosome staining analysis, Kolmogorov-Smirnov test for trajectory analysis, and two-way ANOVA with Bonferroni’s post hoc test for comparisons among multiple groups; *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001; *****P < 0.00001. NSC, neural stem cell; NSC_M, NSC in mitosis; IPC, intermedi- ate progenitor cell; IPC_M, IPC in mitosis; PN, projection neuron; MG, microglia; CR, Cajal-Retzius; VZ, ventricular zone.
