Fig. 2. Luminescence profiles of
[Ca2+]i in embryos injected with
aequorin into different locations at the
8-cell stage. (A) Aequorin injected
into ventral micromeres is located in
the ventral ectoderm during
gastrulation. When injected into
equatorial locations of either (B)
ventral or (C) dorsal micromeres, it
becomes located in the ventral and
dorsal mesoderm, respectively.
(D) Aequorin injected into the
macromeres is located in the
endoderm during gastrulation. In each
panel the inset illustrates the location
of the injection site (left) and the
subsequent location of the aequorin
during gastrulation (on the right;
shaded zone). Under all these
injection protocols, no significant
[Ca2+]i increase was detected.
AP, animal pole; VP, vegetal pole;
V, ventral; D, dorsal.
