Fig. S1. Delta expression profile at the fifth cleavage (32-cell stage). (Aa) Double-fluorescence and DIC picture of a 32-cell stage embryo stained for Delta (olive). (Ab,Ac) Confocal images of the Aa embryo with nuclei in blue. In Ac only, the outlines of the Delta expression domain have been conserved to count number of Delta-positive cells.
Table S1. Average calculated number of cells expressing Delta, Gcm, FoxA and T-brain over time, and total number of embryos analyzed by confocal microscopy for each gene at the various developmental stages tested. The �+� column reveals the number of cells that express the gene studied, the �−� column designates the number of cells at the center of the ring that do not express that gene. Numbers in between parentheses indicate s.d.
