(A–C) ChAT immunolabeling and mosaic analysis of retinal explants cultured with DMSO (A), Wnt3a (B), and XAV939 (C) (N = 6 each), showing Voronoi tessellations, Voronoi areas, nearest-neighbor plots, and frequency distributions for ChAT+ SACs.
(D) Voronoi domain RI (VDRI) and nearest-neighbor RI (NNRI), effective radius (ER), and ChAT+ cell numbers in retinal explants cultured with DMSO, Wnt3a, and XAV939. Plots show means ± SEM. N = 3 biological replicates, each with 3 technical replicates in one experiment. The p values were calculated with one-way ANOVA and post hoc Tukey test.
(E) Pax6 immunolabeling and quantification of P14 wild-type and Ctnnb1cKO retinas, showing ectopic Pax6+ cells in the IPL and ONL in Ctnnb1cKO retinas. Plots show means ± SEM. N = 3 biological replicates, each with 3 technical replicates in one experiment. The p values were calculated with an unpaired t test in pairwise comparisons.
(F) Schematic of the radial migration route of newborn amacrine cells. Scale bars: 50 μm (A–C) and 100 μm (F). See also Figure S7.
