Fig. 4. Crip1 spatial expression pattern during X. laevis embryogenesis. Embryonic stages are indicated in each panel. The white dashed circles depict the cement gland. (A) At stage 3, embryos were negative for crip1 expression (lateral view). (B) Anterior view of a stage 13 embryo. Crip1 was expressed in the anterior neural plate (black arrowhead). (C) The anterior view of a stage 20 embryo shows crip1 expression of in the anterior neural tissue (white arrowhead). (D-H) Lateral views with anterior to the left. (I-K) Ventral views with anterior to the top. (D) At stage 25 crip1 transcripts were detected in the migrating cranial neural crest cells (orange arrowhead) and at the dorsal side of the embryo (green arrowhead). (E-F, I) Crip1 was expressed in the hyoid arch (ha), in the dorsal aorta (da) with a stronger expression in the posterior part (green arrowhead) and in the ventral blood islands (violet arrowhead). (G-H) In later stages crip1 transcripts were strongly detected in the head mesenchyme, namely the quadrate cartilage (QC), ceratobranchial cartilage (CBC), and ceratohyal cartilage (CHC) as well as. Crip1 transcripts were in the dorsal aorta (da) detected. Furthermore, crip1 was expressed in the pronephric tubule convolute (black arrow) and in the posterior cardinal vein (pcv). The stomadeum including the region where the cloaca will form (blue arrowhead) as well as the tip of the tail (yellow arrowhead) showed a strong crip1 expression, too. (J-K) Also the second heart field (red arrowhead) and ventral aorta (va) were positive for crip1. Image published in: Hempel A and Kühl SJ (2014) Copyright © 2014.
