Expression of two potential targets of FGF signaling, NvSprouty and NvChurchill. The expression profile of NvSprouty largely follows that of NvFGF8A and NvFGF1A during embryogenesis, with a few notable exceptions. NvSprouty is first expressed in presumptive endoderm during blastula-stages (a). During gastrulation, NvSprouty is expressed broadly in the blastopore and invaginating endoderm as well as at the apical tuft (b, c). In planula development, the oral/aboral expression pattern remains, although it expands orally such that expression is seen in the ectoderm and endoderm of the apical tuft (d, e) in the ectoderm and endoderm of growing tentacles (e, f) and in a broad domain in the pharynx (df). Transcripts to the zinc finger transcription factor NvChurchill are not detectable during cleavage (data not shown) and gastrulation (g). Expression begins during planula stages (h) in body wall endoderm near the oral pole. During polyp formation, expression is restricted to a ring of cells in the pharyngeal endoderm (il), where it remains expressed throughout juvenile stages (k, l). The asterisk denotes the blastopore and future oral pole. (ph pharynx; at apical tuft; ten tentacle; t. ect tentacle ectoderm; t. end tentacle endoderm, b. end body-wall endoderm) All embryo views are lateral, except (c), (j), and (l), which are oral views
