Figure 3From: Genome-wide analysis of the sox family in the calcareous sponge Sycon ciliatum: multiple genes with unique expression patternsExpression of SciSoxB and SciSoxC during embryogenesis. SciSoxB is strongly expressed in oocytes and during cleavage (A); the expression gradually decreases from the late cleavage (B, top right) to pre-inversion (B, bottom left), becoming limited to the cruciform cells (cc) in pre-inversion stage embryos (B and C) and macromeres (asterisk) of pre-inversion stage embryos (C) and larvae (D). SciSoxC is expressed in oocytes (E) and during cleavage (F); in pre-inversion stage embryos expression is limited to macromeres (asterisk) (G, H) and becomes undetectable in the larvae (I). All images are of glycerol-cleared slices of sponges containing developmental stages, except of D, demonstrating an isolated larva.Back to article page
