Boxplot showing thionin-positive cell count average in the SG (II–III) and IG (V–VI) lamina in NTD (n = 9) and DS (n = 10). Statistical analysis revealed a significantly greater number of cells in SG compared to IG for both NTD and DS (Wilcoxon signed rank test, NTD p = 0.004; DS p = 0.027). No significant differences were found in the SG and IG layers between groups (Mann–Whitney rank sum test). *p < 0.05
