Fig. 4. The cdc-25.1(gf) defect is specific to the E lineage. (A) mom-2 embryos produce extra mesoderm at the expense of endoderm, as seen by anti-PHA-4 staining, which marks pharyngeal precursors (descendants of the MS blastomere). (B) cdc-25.1(gf); mom-2 embryos have similar amounts of mesoderm as mom-2 mutants alone. (C,D) The embryos in A,B have similar cell numbers measured by counting DAPI stained nuclei: (C) mom-2 embryo in A; (D) the cdc-25.1(gf); mom-2 embryos in B. C. elegans embryos are approximately 50 µm in length.
