Effects of pard3 suppression on apical determinants. Immunohistochemistry was performed on transverse cryosections of wild-type and pard3 morphants. Phalloidin was used to label actin (red) in all panels. (A–B) Transverse cryosections of wild-type and pard3 morphants stained with phalloidin (red) and PrkCi immunoreactivity (green). Arrows mark longitudinal fibers in the ellipsoid. (C–D) Cryosections stained with phalloidin (red) and Crb immunoreactivity (green). (E–F) Cryosections stained with phalloidin (red) and ZO-1 immunoreactivity (green). Sections were also counterstained with DAPI (blue). ONL = outer nuclear layer; OPL = outer plexiform layer; INL = inner nuclear layer. Scale bar = 10 µm.
