Fig. 5 Expression of zebrafish apcdd1 and effects of functional knockdown on embryonic patterning. A-G. Domains of expression of various markers of gastrula-stage embryos. Expression of chd in the organizer and vent in ventrolateral mesoderm (A, B, animal pole view) and dkk1 in the organizer (C, lateral view). The organizer is expanded laterally at 6 hpf in apcdd1l morphants, and there is a corresponding contraction of ventrolateral tissue. At 10 hpf, expression of brachyury-a (ta) in the notochord (D) and otx2b in the anterior neural plate (E) (dorsal views, anterior up) are expanded in apcdd1l morphants, whereas expression of ventral marker tp63 in epidermal ectoderm (G, lateral view) is contracted. At this time, expression of bmp4 at the ventral midline (F, dorsal view) begins to upregulate and expand in apcdd1l morphants, presaging subsequent ventralization. At least n = 15 zebrafish embryos were examined for each time point and experimental condition.
