Fig. 2. POP-1 in wild-type and mom mutant embryos. Images are of
AB32 stage embryos. (A,B) Wild-type. (C,D) mom-2(or42)
mutant. (E,F) mom-2(or42);mom-5(RNAi) embryo. Left panels show
embryos stained for POP-1; chevrons indicate examples of sister cells. Right
panels show DAPI and PKL-2 images superimposed; small arrows indicate examples
of midbodies between sister pairs. For each of the sister pairs indicated in D
(small arrows), the anterior sister has low POP-1. POP-1 staining is cell
cycle-dependent and not detected in prophase or anaphase nuclei (large arrows
in B,D) (see also Lin et al.,
1995). In all panels anterior is left; in B,D and F ventral is
down (arrowhead indicates the P4 cell).
