Fig. 6. Analysis of neural plate markers following DAPT treatment at different embryological time points. Graphs show the percentage of embryos with strong, weak or ectopic expression. Scoring was carried out as indicated for Fig. 5. Numbers shown above the bars indicate the total number of embryos analysed. On the x-axis is shown the developmental time point when embryos were placed in DAPT inhibitor: C, control; 44, 76, 110 = cell stage; eG, early gastrula stage.
