... Three types of intercellular junction were observed in the developing retina of Xenopus laevis. The first type is similar to the zonula adhaerens described in various epithelial tissues (Farquhar & Palade, 1963) and occurs between adjacent cells at the outer border of the optic vesicle (Figs. 2, 4). ...
