Fig. 1. Analysis of cell behaviors in wild-type embryos. (A-H) Cross
sections through the anterior neuroepithelium of mGFP (green) and DAPI (blue)
labeled embryos. Dorsal is towards the top in all panels; developmental stages
are indicated in the upper right corner. C is a composite of multiple focal
planes. All other panels are single frames. The insets in C and D are higher
magnifications of the boxed in areas. s, superficial cells; d, deep cells;
lat, lateral region; med, medial region. Double arrowheads indicate the
angular orientation of cells, the dotted red line in C indicates the midline
of the neural keel and the dotted white line in D outlines the neural keel.
Scale bar: 20 µm.
