Fig. 8. Belladonna regulates Vax gene expression in the preoptic area. Anterior is
to the left in the dorsal views of heads of noi-/-
(noi) (A,B), shh-injected noi-/-
(noi+shh) (C,D), bel-/- (bel) (E,F), and
shh-injected bel-/- (bel+shh) (G,H) embryos. Note
that the expression of Vax genes is reduced in the preoptic area but not in
the optic stalk and ventral retina of bel-/- embryos (E,F,
compare with Fig. 2G,J).
Abbreviations: os, optic stalk; poa, preoptic area; r, retina.
