FIG. 4. Both X. laevis Slug promoters
drive specific expression in
NCCs. Constructs containing the GFP
coding region under the control of the slug
or slug promoter were injected into
one blastomere of a two-cell stage embryo,
and GFP levels were monitored throughout
early development. The dashed lines
indicate the midline of the embryo. e, eye
vesicle; c, cement gland. With both constructs,
a pattern similar to that for endogenous
Slug was obtained. Note that at
stage (St.) 25 NF, migrating cells colonizing
the branchial arches were still GFPpositive,
but the signal was weaker because
the acquisition time required to
detect it was three times longer (inset in
the upper right panel).
