Fig. 4. Inhibition of Ena/VASP function does not perturb patterning of the PSM. (A,B) Embryos stained for ß-tubulin, which outlines the periphery of cells, shows that expression of AP₄-mito (A) or FP₄-mito (B) does not alter the distribution or morphology of cells in the PSM following gastrulation. (C-H) Inhibition of Ena/VASP function does not affect the intensity or distribution of paraxial protocadherin (PAPC; C-E) or MyoD (F-H). Injected side is marked with an asterisk in each panel. Anterior is at the top. PAPC: AP₄-mito, n=10; FP₄-mito, n=17. MyoD: AP₄-mito, n=7; FP₄-mito, n=17. Scale bar: 100 µm.
