Figure Lengend Snippet: Figure 2. RBL2 regulates cell fate specification between neuroepithelium and neural crest (A) RBL2 is necessary for neuroectoderm formation. Immunostaining of neuroectoderm markers in Scramble and RBL2 KD cells. Scale bar, 100 mm. (B–D) RBL2 controls the balance between neuroepithelial versus neural crest specification. (B) qPCR, (C) western blot, and (D) flow cytometry analysis of SOX1, PAX6, p75, and SOX10 in RBL2 KD and Scramble at day 4 neuroectoderm. (E) Loss of RBL2 in neuroectoderm specification changes the expression of Wnt and Notch pathway components and HoxA-D genes (see Table S1 for full results). (F) Principal-component analysis (see Table S1 for full results). All data are shown as mean ± SD (n = 3). Statistical analysis was performed by two-way ANOVA with multiple comparisons with Tukey correction; ****padjusted < 0.0001, ***padjusted < 0.001, **padjusted < 0.01, *padjusted < 0.05. See also Figures S2 and S3.
