Fig. 3. Fgf signaling is not affected in the tailbud of wnt3a/wnt8
morphants. The expression of sprouty4 was examined at the 5-somite
(A-D) and 10-somite (D-H) stages in wild-type (A,E), wnt3a MO (B,F),
wnt8 MO (C,G), and wnt3a/wnt8 morphants (D,H). All embryos
are shown in dorsal views of the tailbud, with anterior to the top.
