Junctional complexes have been investigated in the epiblast of young chick embryos by examination of freeze-fracture replicas and of sections of comparable specimens stained with lanthanum nitrate. By means of freeze-fracture, tight junctions were shown to be present in the unincubated embryo (stage 1 of Hamburger and Hamilton). The number of ridges or grooves was found to vary between 2 and 10 near the dorsal border, whereas isolated ridges were found more ventrally. Lanthanum was unable to… CONTINUE READING
