Figure 4. Cm-XBMP-7 induces cement
glands in animal cap ectoderm. Animal cap
explants from embryos injected with dominant-
negative constructs. Uninjected control
animal caps, at stage 35 equivalent, remain
as atypical epidermis (A). Animal cap
explants, at stage 35 equivalent, from Cm-
XBMP-7 mRNA (0.8 ng)-injected embryos
differentiate into cement glands (BJ, as revealed
by pigment aggregation. (C] Histological
sections of animal caps from Cm-
XBMP-7 injected embryos at stage 40 equivalent.
Open arrows indicate ectopic cement
glands. (D) Coinjection of wild-type XBMP-7
mRNA (0.8 ng) with Cm-XBMP-7 mRNA
(0.8 ng] blocks cement gland formation. (E)
Ectopic expression of wild-type activin
mRNA (0.5 ng) results in elongation of animal
cap explants. (F) Coinjection of wildtype
activin mRNA (0.5 ng] with Cm-activin
