Fig. 2 Neurod:EGFP transgene expression at 48 hpf in hsp:wnt8 embryos HS at sphere stage. (A) Control embryos in which GFP (green) is expressed in the head and central nervous system. A range of phenotypes was seen in HS embryos (B, D). GFP expression delineates a shortened trunk and absence of eyes (B), and a severely shortened and twisted posterior axis (C). In an embryo without discernible structures, GFP expression shows evidence for neural induction (D). (in A′–D′, the GFP signal is shown without brightfield). GFP.
