Fig. 6

EphB receptors are surface-localized at the roof plate boundary. (A) Ephrin-B2/Fc binds to HC axons only within the commissure (arrow) at 3 dpf. (B) Ephrin-A2/Fc affinity probe indicates surface localization of EphA receptors in the HC, the habenular neuropils, stria medullaris and tract of the habenular commissure at 3 dpf. (C–F) Higher magnification view of the right habenula labeled with the nuclear stain Syto-11 (C), acetylated tubulin (D) and Ephrin-B2/Fc (E) shows that EphB receptors are surface-localized at the medial boundary of the habenula (arrowhead). (G, H) Ephrin-B2/Fc binding is detected in a wild type (G) but not in a mutant (H) at 2 dpf. (I–L) Immunofluorescence with a pan EphB antibody at 2 (I, K) and 3 (J, L) dpf. Labeling is detected in wild type habenular commissure axons, with stronger label in the commissure at 3 dpf (I, arrow). Mutant axons are labeled at 2 dpf (K, arrow), but not at 3 dpf (L). rHb: right habenula; lHb: left habenula.
