"In wild-type animals, the ablation of E results in embryos that arrest embryonic development with no endoderm. In Fig. 5E we show that early E blastomere ablation in
cdc-25.1(gf) animals results in the complete absence of intestinal cells, indicating that the extra intestinal cells in
cdc25.1(gf) animals result exclusively from the additional cell divisions of the E cell descendants"
