Figure 3. Neural markers expressed in the Stage 29 shark embryos.
Immunostaining staining for GFAP (A, B, D), Tuj1 (C, E) and HNK-1 (F-H), in a st.29 embryo. GFAP stained neural tube (A) and lateral line (arrowhead in D), spinal nerves (arrows in B) and migrating myoblasts (arrow in D). Lateral line (arrowhead in E) and spinal nerves (arrow in E) are also positive for Tuj1. F show a cartoon of a stage 29 embryo with line indicating the level of images in figures.
