Fig. 4. Generation of POP-1 polarity at the AB2 division. (A,B) Example
of an a/p division of an AB2 cell in a
goa-1(RNAi);gpa-16(RNAi) embryo; EMS also divided a/p. (C,D) Division
of laser-fused AB2 cells in a wild-type embryo. (E,F) Division of
an AB2 cell in a devitellinized wild-type embryo after grafting on
a wild-type P2. (G,H) Division of an AB2 cell in a
devitellinized wild-type embryo after grafting on a mom-2 mutant
P2. Panels labeled as in Fig.
2; images of PKL-2 staining are superimposed on the DAPI images in
F and H with midbodies indicated by arrows.
