Figure 3From: Evolution of the Pax-Six-Eya-Dach network: the calcisponge case studyExpression of Pax, Six and Eya genes in adult sponges. A-C; SciPaxB is expressed in all choanocytes and a fraction of mesohyle cells. D-F, SciSixA and G-I, SciEya, are expressed in choanocytes of the radial chambers, but not choanocytes located in the upper region remaining in asconoid organization. A, D and G are upper parts of whole young sponges, B, E and H are magnifications of radial chambers, C, F and I are plastic sections through the radial chambers. Abbreviations: me, mesohyl cells; ch, choanocytes; arrows indicate strongest expression.Back to article page
