Fig. 8. Ectopic expression of mouse Snail also increases neural crest production in the chick hindbrain. Electroporations were carried out as described in the legend to Fig. 1. (A,B) GFP expression and DiI labelling identifying neural crest emigrating from the hindbrain. In C a similar embryo shows ectopic rhoB expression (blue). (D) A high power view of premigratory and migratory neural crest. Arrowheads indicate regions of ectopic expression. Note the amount of rhoB-positive cells at the level of r5.
