Expression patterns of S. kowalevskii foxF - L1. Spatial expression pattern of S. kowalevskii foxF - foxL1. Animals are oriented as indicated in cartoons of Figure 2 (1-5) for the corresponding stage if not otherwise specified. For a detailed description of the expression patterns see text. Panels 4, 8, 9, and 17-19 show surface views. (5) White arrow in panel 5 points at endodermal expression domain of foxF at the tip of the proboscis, black arrow points at the heart-kidney complex. Inlay shows dorsal view of the pharynx, black arrow points at the heart-kidney complex. White asterisk indicate expression in the pharyngeal mesoderm. (9) Panel 9 shows dorsal surface. Inlay shows ventral surface. (10) Arrow in panel 10 points at dorsal mesoderm. Inlay shows dorsal view of the pharynx, black arrow points at dorsal mesoderm. (15) Black arrow in panel 15 points at posterior endoderm expression of foxI. Inlay shows dorsal view of the forming gill pores. (20) Inlay shows dorsal view of the forming gill pores. Black arrow heads point to gill pouch endoderm. (30) Inlay shows dorsal view of the forming gill pores.
