Fig. 1

Expression patterns of fzd genes examined in this study.

Name of each gene is indicated at top left corner. Panels Aa, Ba, Ca, Da, Ea, Fa, Ga, Ha, Ia, Ja are left side views at 1-somite stage, anterior to the top. Panels Aa′, Ba′, Ba′ ′, Da′, Da′, Ha′ are dorsal views with anterior to the top. Panels Ab, Bb, Cb, Db, Eb, Fb, Gb, Hb, Ib, Jb are left side views at 18 hpf stage, dorsal to the top. Panels Ac, Bc, Cc, Dc, Ec, Fc, Gc, Hc, Ic, Jc are left side views at 30 hpf, dorsal to the top. Da′ ′ ′ and Db′ are flat mounted view of fzd4 at 1-som. and18 hpf, respectively. Anterior to the top for D′ ′ ′, and to the left for Db′. Da′ ′ ′ shows only right half of the embryo. The left edge of the embryo corresponds to the midline. For descriptions, see main text. All images are taken at the same magnification. Abbreviations: cp, cranial placode; nm, neuromast; prim., posterior lateral line primordia. Scale bar in Da′ ′ ′ is 200 μm, and one in Jc and for all is 100 μm.
