Figure Caption

Fig. 3 Roles of Wnt Signaling Components in Pouch and CB Cartilage Development(A–L) Alcama immunohistochemistry (green) shows defects in pouches in mutant, fzd8a-MO, and transgenic embryos. Identifiable pouches are numbered. UAS transgenic embryos (capitalized) were doubly positive for nkx2.3:Gal4VP16. Scale bar, 40 μM.(M–X) Whole-mount views of dissected facial cartilages. Arrows indicated fused or abnormal CB cartilages. Arrowhead indicates abnormal hyoid cartilage in fzd8a-MO embryos.(Y–AA) Superimposition of initial (blue) and final (red) still images from time-lapse recordings of fifth pouch development in wild-type, wnt11r^-/-, and wnt4a^-/- embryos. Colored lines indicate cell tracks (shown also below merged images), with filled circles denoting final positions.(AB) Average pouch cell speed in wild-types and mutants. Data represent mean ± SEM and p values are shown for each comparison.See also Figures S1 and S2 and Movies S3, S4, and S5.
