Expression patterns of S. kowalevskii foxA - E. Spatial expression pattern of S. kowalevskii foxA - foxE. Animals are oriented as indicated in cartoons for the corresponding stage if not otherwise specified. For a detailed description of the expression patterns see text. Panels 1 to 5; ectoderm = light gray, mesoderm = light blue, endoderm = dark gray, black arrows in panel 4 point at the forming furrows at the boundary between the proboscis and collar and collar and trunk respectively. Panels 6, 11, 16, 19, 21, and 31 show surface views. Panels 17/18 are lateral views. (10) Panel 10 shows a dorsal view, white arrows points at the forming gill pores, the black arrow points at the gap of ectodermal foxA expression at the dorsal collar, inlay shows lateral view. (15) Inlay in panel 15 shows ventral view on the mouth opening, white arrow points at the mouth opening. (20) White arrow in panel 20 points at the endodermal expression domain of foxB. (30) White star in panel 30 indicates the ectodermal expression domain of foxD at the base of the proboscis. The inlay shows a closeup of the posterior gut region. An: animal pole; Veg: vegetal pole; L: left; R: right; A: anterior; P: posterior; D: dorsal; V: ventral; ao: apical organ; cb: ciliated band; gp: gill pore. Brightness and contrast of pictures were adjusted when appropriate to match overall appearance of the figure.
