Figure 1. Whole-mount in situ hybridization
analysis of XBMP-7 transcripts. (A]
Animal view of stage 9 embryos. (Left)
Sense RNA-hybridized embryo; (right) antisense
RNA-hybridized embryo. (B-Dl
Stage 10.5 embryos. (3)A nimal (left] and
vegetal (right] views; (C] lateral view; (Dl
vegetal view. (E,F) Stage 20 embryos. (E)
Dorsal view; (F) anterior view. (G,H) Stage
22 embryos. (GI Lateral view; (HI dorsal
view. XBMP-7 transcripts are detectable in
the entire marginal zone mesoderm including
the organizer region (arrows in B-Dl.
Note that the ectoderm of both blastulae
and gastrulae strongly express XBMP-7
mRNA and the expression is lacking in the
endoderm. XBMP-7 transcripts are expressed
predominantly in the cement gland
and eye anlagen (arrowheads in E,F). At
early tailbud stages XBMP-7 is expressed in
the cement gland, heart anlage, proctodeum,
eyes, and midline of the anterior
neuroectoderm (arrowheads in G,H]. Dorsal
is to the top in D, F, and G, and to the
right in B and C. Anterior is to the left in E,
G, and H. Image published in: Hawley SH et al. (1995) Copyright © 1995. Image reproduced on with permission of the Publisher, Cold Spring Harbor Laboratory Press. This is an Open Access article.
