Fig. 8. Developmental analysis of the localization of nectin 1, nectin 2, nectin 3 and afadin at the apex-apex junctions between the pigment and non-pigment cell layers of the ciliary epithelia. E15.5 (left), E16.5 (middle) and P0 (right) mice. The bottom row shows DIC microscopic images. PE, pigment epithelia; NPE, non-pigment epithelia; L, lens; R, retina. Insets show higher magnifications of the boxed areas. Scale bars, 50 µm.
