Fig. 3. Expression of the X. laevis noggins at the stages 24 and 26. (A–F) Results of the whole-mount in situ hybridization. All embryos are shown from the right side, anterior to the right, dorsal upward. Embryos shown on C and F were cleared in the mixture of benzyl benzoate and benzyl alcohol. (D1–F4) Histological sections of embryos hybridized in whole-mount. (D1 and D2) Sections of embryos at stage 24 at the levels indicated on (D). (F1–F4) Sections of embryos at stage 26 at the levels indicated on (F). On D1, F1 and F2, dorsal to the top; on D2, F3 and F4, anterior to the right. Abbreviations: Ba—branchial arches; Cg—cement gland; Fb—fore brain; H—heart; Hb—hind brain; Mes—mesencephalon; Nc—neural crest cells; Nt—neural tube; Not—notochord; Ov—otic vesicle; Pe—presumptive pigmented epithelium; Ret—retina; Sm—somites. |
