Fig. 3. Phenotypes after blastomere injection at four to eight cell stage of Wise RNA (B,E,H,K,N,Q) or antisense morpholino oligonucleotides (C,F,I,L,O,R) in comparison with control embryos (A,D,G,J,M,P) assayed by whole-mount in situ hybridisation at neurula stages. Marker is noted on the left of the panel. In most embryos, lacZ RNA was co-injected as a lineage tracer (blue staining). Injected side is to the left of each panel.
