Figure 7. Retinal cross-sections obtained from tg21 mice no b-wave mice and control littermates were stained for GPR179. Positive staining is seen as punctate distribution in the outer plexiform layer of control mice, and is absent from retinas of tg21 no b-wave (nob) mice. Abbreviations: OPL represents the outer plexiform layer; ONL represents the outer nuclear layer; INL represents the inner nuclear layer.
