Fig. 6. Zebrafish dorsal organizer formation impaired by NB 12E. (A) Schematic representation of the observation for early development of zebrafish. (B) Brightfield images of the wild-type (WT) embryos at the indicated stages after the injection of 7 μM RSL3/12E/4C and PBS (the injection volume is 1 nL). The red arrow indicates the reduced ventral tail fin. The frequency of embryos with the indicated patterns is shown in the bottom right corner of each panel. Lateral views with anterior to the left. Scale bar = 500 μm.
