Fig. 8. Anti-ß-catenin antibody stainings of wild-type embryos (A-G). (A-C) Confocal photographs of a z-multilevel apicobasal scan (0-6 indicate 3 µm steps) through the neural plate. No local accumulation of the epitope can be distinguished. (D-F) A similar scan through the neural keel, to illustrate the incipient apical localisation of ß-catenin (arrows) (0-16 indicate the distance in µm). (G) The neural tube, in which the epitope is clearly concentrated apically (arrows).
