Comparison of AMG in wild type, <i>mam^ΔC</i> and <i>N^55e11</i> mutant embryos and embryos overexpressing <i>Notch</i> and <i>EGFR</i> signaling components during mid and late embryogenesis.

The number of AMG found in a single CNS segment of wild type, mamΔC and N55e11 mutants and embryos overexpressing the NICD (UAS-NICD sim-GAL4), Su(H) (UAS-Su(H) sim-GAL4), mam (UAS-mam sim-GAL4) or spi (UAS-sspi sim-GAL4) in the midline and embryos overexpressing spi in the midline of mam mutants (mamΔC UAS-sspi/mamΔC sim-GAL4) at stages 13 and 16 is shown. Results are shown as means ± SEM and the sample size is indicated in parentheses. Stage 13 ANOVA: F8,110 = 140.18, P = 0.0001 and stage 16 ANOVA: F7,90 = 147.99, P = 0.0001. Within a column, treatments with different letters are significantly different (Tukey-Kramer HSD, P<0.05).
