PAR-1::GFP is expressed ubiquitously during embryogenesis and is enriched in the embryonic germline. Photomicrographs of live embryos expressing PAR-1::GFP. PAR-1::GFP is enriched at cell cortices and segregated preferentially to the germline. In each panel, the embryonic stage is indicated in the upper left and the names of the germline blastomere for that stage is indicated in the lower right. Solid arrowheads indicate the two primordial germ cells (Z2 and Z3). A smaller open arrowhead in the 2-fold stage panel points to the lobe of one of the primordial germ cells (Abdu et al., 2016). Scale bars: 5 μm.
