sna-1 expression after ectopic expression of ntl in intact embryos (A,B; stained for Ntl protein and sna-1 mRNA) and after activin A treatment of animal caps (C,D; stained for Sna-1 protein). (A) Germ ring-stage embryo. Ntl protein is ectopically expressed in animal regions of the embryo. sna-1 expression is restricted to the germ ring, its endogenous expression domain. (B) Sphere stage. Ntl protein is ectopically expressed and overexpressed in the right part of the embryo (separated by dashes). sna-1 is more strongly expressed at the margin of the right part of the embryo. (C) Expression of Sna-1 protein upon incubation of the animal cap for 5 hours in medium containing activin A. (D) No Sna-1 expression upon incubation in control medium. The animal caps are slightly spread. |
