Fig. 9. Snail controls neural crest migration. One blastomere of a two-cell stage embryo was injected with 700 pg of SnailGR (A,D), its dominant negative (B,E) or SlugGR (C,F) treated with dexamethasone at stage 16, fixed between stages 22 and 23, and the expression of the neural crest markers Slug analysed. (A-C) Injected side (arrowhead). (D-F) Uninjected side of the embryos shown in A-C. The leading edge of migration is indicated with a broken line. Note that SnailGR (A,D) and SlugGR (C,F) produces a stronger migration in the injected side; while the injection of ZnFXsnailGR (B,E) leads to an inhibition in the migration of the crest cells.
