Fig. 1. — PAR-3 localization within polarizing epithelial cells. DNA is blue (in this and all subsequent figures). Anterior is left. C. elegans embryos are ∼50 μm. (A-C′) PAR-3 in polarized intestinal and pharyngeal cells (A), in intestinal precursor cells (IPCs) that are beginning to polarize (B), or during polarization (C). The boxed regions in B,C are shown in B′,C′ and show colocalization of PAR-3 with HMR-1. (D,E) PAR-3 colocalization with HMP-1 (D) and PAR-6 (E) in IPCs at the onset of polarization. (F) Stills from Movie 2 of IPCs expressing PAR-3^YFP (see Movie 2 in the supplementary material). Dashed line indicates the future apical surface. A focus of PAR-3^YFP (arrowhead) is shown over time (minutes). (G) Lateral view of polarizing epidermis (bracketed region) showing apical PAR-3 (arrow) and PAR-6. Scale bars: 2.5 μm.
