Fig. 3
Expression patterns of lgr4 in zebrafish embryos. (A–H) lgr4 expression was examined by whole-mount in situ hybridization at the 5s, 15s, and 18s stages and at 24 hpf. Dorsal views from the anterior (A, C, E, and G) to the posterior (D and F). A vegetal pole view of the tail-bud region (B). A lateral view, anterior to the left (H). Arrow indicates Kupffer’s vesicle; arrowheads indicate the brain ventricular zone; asterisks indicate the weak and ubiquitous expression of lgr4 in the head. bvz, brain ventricular zone; e, eyes; fb, forebrain; kV, Kupffer’s vesicle; mb, midbrain; npb, neural plate border; nt, neural tube; op, optic primordia; ov, otic vesicles.
