Figure 4

AmSoxC shows cell specific expression in the ectoderm from early embryogenesis through post-settlement: (A) Early cleavage stage. (B) Prawnchip stage. (C) Initiation of gastrulation at the early donut stage. (D) Transverse section of C. (E) Donut stage embryo, during gastrulation. (F) Longitudinal section of E. (G) Pear stage. (H) Longitudinal section of G showing that expression is restricted to the ectoderm. (I) Planula stage. (J) Longitudinal section of I. The cell specific expression in the ectoderm continues and oral pore staining is observed. (K) Post settlement polyp. Though the ectodermal cell specific expression becomes weaker, the oral pore staining is still maintained. Paired arrows on a panel of the figure indicate that the next panel is a section in the plane of the arrows (e.g. D is a transverse section of the embryo shown in C).
