Fig. 10. Localization of nectins at the apicolateral boundaries of the pigment and non-pigment epithelia. (A) Localization of nectin 1, nectin 2, nectin 3, afadin, P-cadherin and ZO-1 at the apicolateral boundaries of the pigment and non-pigment epithelia. Wild-type (left,) nectin 1^–/– (middle) and nectin 3^–/– (right) mice. (B) Localization of nectin 1 at the apicolateral boundaries of the pigment epithelia, but not at those of the non-pigment epithelia in nectin 3^–/– mice. (C) Localization of nectin 3 at the apicolateral boundaries of both the pigment and non-pigment epithelia in nectin 1^–/– mice.. PE, pigment epithelia; NPE, non-pigment epithelia; R, retina. Insets show higher magnifications of the boxed areas. Scale bars: 50 µm.
