Fig. 5. Expression of vgll4l and vgll4 at advanced neurula and tailbud stages. (A-I) vgll4l expression. (J-O) vgll4 expression. (A) Dorsal view, anterior to the right. (B, D, F, G, K, M, O) lateral view, anterior to the right. (C, H) Transversal section. Black dashed lines in B and G indicate the positions of the cuts made to give cross-section in C and H. (E, I, N) Higher-magnification views of head region. (J) Anterior view, dorsal to the top. (L) Dorsal view, anterior to the top. (F) Negative control, vgll4l sense probe. (A-B) Asterisk, vgll4l epidermal expression. (A) Arrowhead: vgll4l neural folds expression. (B, D) Arrowhead, vgll4l expression in the migrating neural crest. E, G, I: Arrowhead, vgll4l branchial arches expression. (C) Black arrow, vgll4l expression in the internal layer of the ectoderm. (D, G) Black arrow, vgll4l skin expression. (D, G, H) Red arrow, vgll4l notochord expression. (O) Negative control, vgll4 sense probe. (J-N) Arrow, vgll4 expression in the prospective brain. (J-L) Red arrowhead, vgll4 expression in the migrating neural crest. (M-N) Red arrowheads, vgll4 branchial arches expression. (K, L, M) White arrowhead, vgll4 somites expression. n, notochord. OpV, optic vesicle. OtV, otic vesicle. |
