Fig. 3. X-Delta-1 is expressed in the ventral
ectoderm in a punctate pattern that anticipates
a-tubulin expression. (A-C) Xenopus embryo
(stage 11) stained in whole mount for the
expression of X-Delta-1 by in situ hybridization.
View of the ventral side is shown in A, a lateral
view in shown in B and a transverse section is
shown in C. Note that X-Delta-1 is expressed by
scattered cells within the inner layer of the
ventral ectoderm (A,C), in addition to cells (B,
arrowheads) that are localized to stripes within
the neural plate where primary neurons will
form (np). (D,E) a-tubulin expression is first
detected by in situ hybridization at stage 12 in
the ventral ectoderm (D). Lateral view shows
that a-tubulin is expressed by scattered cells in
the non-neural ectoderm (nne) but not in the
neural plate (np). bl, blastopore. Image published in: Deblandre GA et al. (1999) Copyright © 1999. Image reproduced with permission of the publisher and the copyright holder.
