Fig. 3. Whole-mount in situ analysis of Xom expression. (A) Vegetal
view of a Xenopus embryo at stage 9 shows asymmetric expression
of Xom. It is likely that Xom is most highly expressed in ventral cells,
because by stage 10.5 transcripts are clearly excluded from the
organizer (B). Apparent lack of expression in vegetal tissue is
probably due to poor probe penetration. (C) Dorsal view of an
embryo at stage 12.5; expression is excluded from the anterior neural
plate and the dorsal midline. (D) Dorsal view of an embryo at stage
14. Expression is becoming restricted to two domains, one anterior
and one posterior. The posterior domain surrounds the lateral and
ventral regions of the embryo. (E) Lateral view of an embryo at stage
20. The anterior domain has resolved to mark the dorsal region of the
eye. The posterior domain includes the ventral region of the embryo
and (out of the plane of the photograph) the dorsal midline in the
trunk. (F) Lateral view of an embryo at stage 32 shows expression of
Xom in the dorsal part of the eye, in the proctodeum and in the
tailbud. Scattered expression is also visible in the dorsal midline,
which may be due to migrating neural crest cells. Image published in: Ladher R et al. (1996) Copyright © 1996. Image reproduced with permission of the publisher and the copyright holder. This is an Open Access article distributed under the terms of the Creative Commons Attribution License.
