FIG. 1. Anterior neural markers occupy the same position in explants as in intact embryos. (A) Fate of ectodermal cells in the stage
10-minus gastrula. A point in the dorsal midline, at the midpoint between the bottle cells and the animal pole, was stained with Di-I
(asterisk). Blue lines indicate outline of representative Keller explant. (B) In tailbud embryos (face view, stage 27), the marked point (arrow,
yellow cells) occupies the face plate, between the eyes and posterior to the cement gland. e, eyes; cg, cement gland; ncz, nonciliated zone.
(C) Marking the same region in explants using a glass bead (gb). (D) Explant at tailbud stage (stage 23) stained for cement gland (XAG-1),
and the midbrain–hindbrain boundary (En-2). The glass bead left a hole in the explant (gb) posterior to cement gland. (E) Expression of En-2
and XAG-1 in stage 23 embryo (face view). Image published in: Holowacz T and Sokol S (1999) Copyright © 1999. Image reproduced with permission of the Publisher, Elsevier B. V. Larger Image Printer Friendly View |
